6 Coating: Definition, Types, and Applications Definition The 3-layered Polyethylene (3LPE) is a multilayer, thermoplastic coating designed to provide maximum long term corrosion resistance and mechanical protection to steel pipes. This Technology has the advantages of superior adhesion, cathodic disbondment and impact resistance, where these properties are essential for maintaining pipeline integrity, and durability. Advantages of 3LPE coating in general 1- High Corrosion Protection The 3LPE coating composition guarantees extreme adhesion property of the PE to the steel pipes which ensures no corrosion to the steel and also high resistance to cathodic dispondment in the field. 2- Flexibility of production The flexibility of the 3LPE coating technology gives the ability to apply the coating to steel pipes ranging from ½ to 1 with a wide range of thicknesses meeting any requested standard or customer needs. 3- Very Good Mechanical, Physical, and Chemical Protection The strong layer of polyethylene provides high mechanical and physical strength to the steel pipes that permits it to endure all handling and transportation accidents which consumes money and time to repair, while the chemical structure of the polyethylene provides high protection from soil and wear conditions. Additionally the following advantages are achieved in the 3LPE Systems: High resistance to penetration. High impact strength. Types of Coating: 3LPE( 3 layered polyethylene coating Fusion Bonded Epoxy (FBE) Internal lining High rigidity. High elasticity and resistance to tearing. High electric insulation. High resistance to chemicals and oxidization Withstand high temperatures ; PE resists up to 70 o C, while PP resists up to 1 o C 11

7 Future Iron Pipes applies several types and applications of coatings: 1. Fusion Bonded Epoxy (F.B.E.) Coating FBE coating provides long-term corrosion protection at any condition, The coating is done using electrostatically spray guns that provides uniform and well distributed layer all over the pipe surface. The thickness of the FBE coating is up to 00 microns. F.B.E. coating can be applied per any international standard and any customer specifications. The process of the coating is summarized as follows: Pipe cleaning: This process is done by shooting the pipe with small granules to remove any impurities of oil or corrosion and make the pipe cleaned equivalent to Sa 2 1/2 standard according to PSI 325 and to reach a roughness degree of Rz 0-90 microns according to ISO Heating: The pipes shall be heated according to the raw material specifications of the manufacturer (usually to a degree of -200 o C) in order that the epoxy layer adhere to the pipe surface. Epoxy coating : In this process the pipe is coated with epoxy powder resin as a base layer to protect the pipes from corrosion, this powder is sprayed electrostatically to a thickness larger than 50 microns according to PSI325, thickness is also modified to match any international standard or customers requests. 2. 3LPE coating The composition of the 3 layers is: Base layer (Epoxy) : The base layer is an Epoxy layer that protects the steel, improves the adhesive surface and the resistance to cathodic dispondment. Adhesive layer : This layer role is to improve the adhesion of the polyethylene layer to the epoxy layer and to strengthen its resistance to peeling. Polyethylene layer : Protects the pipe from any mechanical damage or corrosion, it also works as an electric insulator to the steel pipe. 13

8 Polyethylene or Polypropylene coating: In this process the coating is done via co-extrusion technology meaning that the adhesive and the PE or PP are together extruded at the same time through a common exit with thicknesses of microns for adhesive and thickness of PE or PP according to the following table: Cut-Back: The length of the cut back shall be at least 0mm for pipes sizes <, while for pipes sizes larger than the cut back shall be mm with a beveling angle of <30 o unless otherwise noted by the customer. Pipe size (inches) Thickness Normal Medium Large Printing: Each pipe is marked according to appropriate standards mainly the following characteristics are identified: Up to 1.5 mm 1. mm 2.5 mm 1. mm 2.0 mm 2.7 mm mm 2.2 mm 2.9 mm Data are in accordance to PS325 and DIN3070 Cooling: The coated pipe is to be cooled immediately after extrusion to have sufficient surface hardness before the cut back and testing 1.

9 - Coating continuity. The test is done via a holiday detector that detects any porosity in the coating, for each millimeter kv are applied to the coating on a condition that the voltage doesn t exceed 25 kv according to PSI Peeling test This test is done after 2 hours of the coating according to DIN and PSI 325 and the average required force to remove the coating must be according to the following table Coating type Test at o C Test at o C 3LPE 0 N/mm 25 N/mm Quality Control Procedure and Methodology Future Iron Pipes adheres to stringent procedures in testing its products, these procedures are based on the local and international standards, and built to assure the client satisfaction by our products. - Indentation (impact) test The impact test is done by dropping a weight with a 25 mm diameter ball head from an elevation of one meter on several points and the energy produced must be as shown in the following table: Nominal pipe diameter Less than 2.5 From Above Impact energy per mm of coating thickness 3.5 J.3 J 5.0 J Then the continuity test is done to ensure that there are no holes or penetrations in the coating according to PSI Penetration assessment According to the DIN the penetration depth must not exceed 0.2 mm at a temperature of o C and 0.3 mm at a temperature o C. - Elongation at break point. This test is done according to PSI 99 part 3. In this test a pipe is coated without adhesive layer and then the elongation of the specimen is measured at the breaking, the shape and dimensions of the specimen must be according to model A of the standard, the tension speed must be 25 mm/min and the elongation ratio at the break point must be 350%. 1 17

10 Our Quality control plan is summrized as : Properties Method of Test Pipe Surface Visual every pipe blast cleaning and Roughness Using special measuring devices Minimum Production Control twice per shift Internal cement lining: Introduction about the industry The internal cement mortar lining provides protection to the pipeline in two ways. First, it is a cement pipe within a steel pipe, and second, by creating a Zone of Alkalinity. This zone between the cement lining and the pipe wall, neutralizes the corrosive properties of the liquid medium and blocks corrosion of the pipe wall. In effect, the Zone of Alkalinity serves as a second layer of defense against internal corrosion. Unlike other types of internal linings, which allow pipe corrosion to spread down the line once they are chipped or damaged in any spot, the cement lining prevents corrosion from spreading along the pipe wall. Surface preparation Visual 0% inspection Pipe temperature after induction heating Heat sensor continuously Appearance and continuity Visual every pipe Manufacturing Process The lining is applied by using a high-speed centrifugal process. By using this method, excellent quality control of the cement-mortar lining is maintained. The cement linings FIP produces are dense, smooth, uniform, well bonded to the pipe wall, and offer very little frictional resistance to the flow of water. The pipe is spun at a very high rate accompanied by vibration to produce a dense lining. This highspeed lining brings water and latence to the lining surface. The latence is immediately washed out of the pipe with water. The immediate result is a smooth, dense, and well-compacted cement-mortar lining. After the application process, the linings are then cured by sealing the pipes ends for 5 days to prevent too rapid loss of moisture from the mortar. The process of lining the cement internally is summarized as follows: Coating Thickness testing According to standards twice per shift Stage Description Illustration Cut back Visual every pipe Cleaning The internal surface of the pipe is cleaned from any mill residues or tabulations or any accumulation of dirt, rust or oil and grease. Holiday inspection According to standards 0% of all pipes Impact resistance According to standards one per order Lancing The machine is calibrated to apply a specific amount of cement according to the pipe size and the required thickness of the coating and then the cement is applied to the pipe using a cement hose. Adhesion (Peeling resistance) test According to standards on one pipe each 0 coated pipes Spinning The pipe then is spun to distribute the cement uniformly using centrifugal spinning in this way the water to cement ratio is lower and the lining will have improved cement strength. Indentation test According to standards one by order Elongation test According to standards Raw material change Curing After spinning the water is expelled from the pipe then the pipe is closed with a cap to ensure good hydration of the cement mortar, the humidity and temperature are controlled to maximize the strength of the mortar 1 19

11 Requirements Cement mortar lining shall be uniform in thickness, except at joints or other discontinuities in the pipe wall. Lining thickness shall be as listed in the Table below or as specified by the purchaser. Ends of lining shall be left uniform with regard to the longitudinal axis of the pipe, and the lining holdback shall be as specified by the purchaser for the type of joint required. The lining thickness requirements shall be maintained by mechanical-end retaining rings and verified by physical measurements. Pipe size (inch) Coating thickness (mm) Allowed tolerance (mm) , , , +3.0 according to PSI 325 Nominal pipe size Lining thickness tolerance In mm in mm in mm / -1/1 - +1/ -1., /1-1/1 - +1/ -1., +3.2 according to AWWA C Materials and Application Raw Materials Sand Fine aggregate for cement mortar consists of sea washed sand, with a 0% percent passed Sieve No.. Sand provided to the plant is usually sieved, to prevent any larger size stones, from enterning the mixture. When the source of material is changed, new sieve test is to be conducted. Cement A - Portland cement. The used cement is Portland cement,cement is stored in a weather-tight, dry, and well ventilated. Cement containing lumps is rejected and not used in the lining process. B -Sulfate resistance cement. Sulfate resistance cement (SRC) is primarily used when the nature of the environment is highly concentrated with sulfate that would generate several reactions that could attack the cement and damage it such as sewage water and highly concentrated soils. Applications: specially used for lining sewage usage pipes due its high durability and resistance against sulfate attacks. Advantages: Excellent durability to sulfate attack due to low C3A and low alkali content High strength Low alkali reduces the availability of the sulfate ions to react with the C3A thereby further improvement to sulfate attack resistance. Mixing & Application Preparations Before lining, surfaces to be lined shall be cleaned to assure the removal of any impurities and mill residues that could affect the adherence between the lining and the pipe internal surface, the mixture shall be homogenous without containing any impurities that affect the lining quality Placement During the application of the lining by a spinning machine, the entire quantity of mortar required for completion of the lining of the pipe section shall be placed without interruption. After the cement mortar has been distributed to a uniform thickness, the spinning speed is increased to produce a dense mortar with a smooth surface. Surplus water is removed by tilting the pipe when moving on the outbound rack. The lining at the ends of the pipe section shall be left square and uniform with regard to the longitudinal axis of the pipe, and the lining holdbacks shall be as specified by the purchaser for the type of joint required. The default ends have no holdbacks. Lining of Fittings The application of cement mortar lining to, tees, elbows, reducers, and other special sections, is accomplished by mechanical placement, or hand application and finished to produce a smooth, dense surface. Areas to be lined shall be cleaned to remove loose or other foreign matter that would interfere with the adherence of the cement mortar and, if necessary, shall be moistened with water just before the placing of the cement mortar. Curing Water The water used for cement mortar and for curing linings or coatings shall conform to the applicable requirements of ASTM C9. The used water is fresh potable drinking water free from injurious amounts of oil, acid, strong alkalies, salts, or organic matter. Immediately after completion of spinning, the pipe sections are moved to a curing area. Care shall be exercised to prevent damage to the lining. The total curing period shall be equivalent to 9 hr of moist cure and the minimum. The lining shall be kept continually moist until completion of the minimum specified curing period. On arrival at the curing area, but not later than 30 min after completion of the lining operation, pipe ends are covered with plastic during thecuring period. Sampling and Testing Mixed cement mortar for pipe-lining work are sampled from each working day. Compression test samples of (cm x cmxcm ) are prepared to satisfy the quality control requirements of the used standards or the client requirements. The samples shall attain compressive strength of 31 MPa (cylinder) in 2 days or at the time of shipment if less than 2 days

12 Repair Lining repair Defects, including but not restricted to sand pockets, voids, over sanded areas, blisters, and cracking as a result of impacts, shall be removed and replaced by hand or pneumatic placement to the same thickness as required for the cement mortar lining. Lining Cracks Temperature and shrinkage cracks in the cement mortar lining less than 1/1 in. (1. mm) in width need not be repaired, since they autogenously repaired under continuous soaking in water. Cracks wider than 1/1 in. (1. mm) shall be repaired by applying cement water grout, and spin the pipe to insure that the cracks are filled with the grout. Special Concerns The purchaser of cement mortar linings is cautioned about the following concerns: Soft, aggressive waters. Soft, aggressive waters, as well as prolonged contact with heavily chlorinated water, may be injurious to cement mortar linings. When this environment is anticipated, further studies may be necessary to determine the suitability of this type of lining. Flow velocity. Cement mortar linings perform best when flow velocities are in normal ranges. When the flow velocity exceeds approximately.1 m/sec, special studies may be required to determine the suitability of this type of lining material. Health Effects: Compliance with NSF/ANSI 1, or relevant health standards for Drinking Water System Components is necessary, and shall be confirmed.

14 Installation Applications Handling and storage: Heat shrinkable sheets: Heat shrinkable sheets are used to cover the welding areas between any two pipes in order to make sure that no corrosion is permitted in the area of welding to assure full protection of pipes. Future Iron Pipes recommends the use of these sheets since the moisture penetration to the pipes is a very costly issue to the water lines and a costumer can request this type of sheets at the facility A reasonable amount of care in handling the pipe should be taken during stockpiling. The necessary measures are taken to insure that the pipes will not be dropped, dragged, or bumped against other pipe or objects, or climbed on. Other items, such as, fittings, and accessories, will be stored in a convenient area away from construction traffic, protected from damage and theft. Safety precautions will be taken during jobsite storage and stockpiling. Coated pipes and fittings will be moved using a crane with a nylon sling or cushioned cable for safe handling. Handling: Basic installation of shrinkable sheets: Clean the area at which a penetration has occurred with steel wire brush, including cm of the PE coated pipes ends. Heat the pipe with a gas burner to o C. Apply the shrinkable sheets and make sure to press the sheet all over the pipe while heating the sheet and then heat the adhesive layer at the ends of the sheet. Advantages of shrinkable sheets: Field friendly No high pre-heat required Easy to install. Low cost. Pipes with beveled ends must be placed in an even and clean ground preventing any type of dirt or stones to contact the pipes this can be assured by using wooden stands that are covered with rubber to protect the coating from any accidental impacts. Lifting and transporting the pipes must be done by using soft non-metallic grips that can be used to bind the pipes without damaging the coatings. Storing: In planning to store the pipes, it must be taken into account to store the pipes in a way that ensures avoiding any unnecessary moving to the pipes bundles, also storing the pipes away from the transportation routes is another way to protect the bundles during storing. It s also recommended to use thick bases to lift the pipes over the ground to protect it from moisture. Bundles: The use of bundles is a good way to store the produced pipes, the pipes sizes that are bundled are 1/2,3/, 1 and 2 while other sizes are packed in a different manner for example a 2 bundle contains 50 pipes, also these bundles are separated with a minimum 3 distance of separation so that they do not contact each other 2 27

15 Bases and separators: Usually the bases and separators are made from wood which must not contain any nails or barks the following table can be very helpful to store the pipes in a proper way. Stockpiling highest above 2 meters is not recommended. Pipe size range Number of separators (layers between pipes) With internal lining Without internal lining mm No. of tones No. of wooden bases used < 2-20 >20 The minimum distance between wooden bases used (for.2m length pipes) must be meters to ensure that the weight of the pipes is distributed evenly on the bases also they must be level and have the same thicknesses, the following figure illustrates the way they must be placed The width of the wooden bases and separators must be at least 0 mm Lifting: The lifting of pipes must always be horizontal to overcome any expected slippage, or failure. It s really important not to use chains, gears or cables to lift the pipes which may cause undesired damage. Rubber or plastic coated slings are recommended for lifting the pipes The correct place to lift the pipes bundles from is ¼ the length of the pipe from each side as in the figure Using a Forklift: It s possible to use a forklift to lift the pipes but there are several considerations that must be done to assure no damages during lifting using forklifts 1- The fork surface must be wide and clean. 2- Pipes products may not be pushed with the forklift. 3- The fork surface must be covered with rubber to avoid damages during lifting - Place the forks of the forklift under the bundle in a way that assures balance of the bundles. 5- Calibrate the speed so that the pipes don t roll on the forks surface. Transporting: The transportation may be done via trucks, trains or ships. While transporting the pipes; the following shall be insured Make sure that there is no abrasion between the pipes or between the pipes and the truck bars, rubber or plastic may be used to cover the bars if necessary. Bases and separators must be used as in storing the pipes to assure the stability of the pipes during transportation, fastening lines also used to tie the bundles with the truck with a minimum width of 5 cm not to damage the coating. Plastic cabs are used to close the ends of the pipes so that dirt or spillages do not enter the pipes (specially drinking water pipes). The maximum number of pipes that are permitted on truck depends on the pipes sizes as in the following table. 2 29

16 Instructions to unloading personnel when arriving at the delivery site: 1. Make sure truck is parked on level ground. If not, have driver move truck to a level area. Engage hand brakes and chock wheels. 2. People not involved in the unloading of the trailer and the truck driver should remain clear of the unloading area. 3. The trucker s chains or straps should be removed from the load only after checking that the load has not shifted and will remain stable. Use caution straightening shifted loads.. Get sure that the forklift have a capacity rating sufficient to handle the load. 5. To prevent possible injury or damage, the forks should slowly enter the pack between the top and bottom boards of the pallet.. Steel bands used for packing elbows, tees, and other fittings should not be removed until the Pallet have been transported to the storage area and secured in a stable and safe manner. 7. Avoid unnecessary standing on the load. Do not remain on the load during unloading operations!. Do not use backhoes, end loaders, or other handling equipment to push or pull the load off the trailer. This is dangerous to unloading personnel and may damage the pipes, and/or their coating.
