7 5.2 AREA TO BE COATED The coating density (120 lbs./ft) and thickness shall be controlled so that the coating weight on any joint All pipe specified in the CONTRACT shall be coated over approximately half of the circumference of the pipe to within a "cutback" of 4 inches from each end. The longitudinal center of the area to be coated shall be offset approximately 150 degrees from the seam weld on the pipe. The area to be coated is also shown in Figure 1. The exposed surfaces of the casing pipe and the "cutback" areas and bevels shall be free of coating and overspray. 5.3 COATING THICKNESS The finished coating shall be uniformly applied to a nominal thickness of 105 mils over 120 o of the outer circumference of the pipe, and feathered down over the adjacent 30 o to zero thickness as shown in Figure 1. The 30 degree feathered zone shall decrease in thickness more or less continuously to no less than half the nominal abrasion resistant coating thickness (in addition to the thickness of the FBE) at 15 degrees beyond the full thickness area. The minimum thickness shall be 90 mils and the maximum, 120 mils. No abrasion resistant coating is required on the remaining half of the pipe. 5.4 WEIGHT FIGURE 1 is not less than the theoretical weight, calculated using the thickness limits specified in Section 5.3 and in the CONTRACT. The theoretical weight of abrasion coating per unit length of abrasion coating is as follows: Coating ThicknessWeight (mils)(lbs./ft) 30" Riser Casing 38" Bundle Casing Specification for Material and Application of Abrasive Resistant Coating on Steel Line Pipe 7 of

8 nominal MANUFACTURING < with clean, dry lint free rags using hydrocarbon solvents (xylol mineral spirits) Bevel Protectors and End Caps Bevel protectors shall be removed from the joint ends and be replaced by suitable caps to prevent coating material entering the bore. The end caps shall be installed in such a manner that they do not cause damage to the pipe markings inside the bore Masking 6.1 TRANSPORTING, HANDLING AND STORING OF LINE PIPE CONTRACTOR shall be responsible for the safe transportation, handling and storage of the pipe according to COMPANY specification number SP 051. Care should be taken not to damage or obscure the markings inside the pipe. The pipe shall not be racked in more than three tiers. If CONTRACTOR intends to move the pipe before the coating is cured, then the reasons for this, the time between coating and the move and procedures for handling shall be included in CONTRACTOR's work plan. 6.2 UNDERCOATING AND PREPARATION FBE Undercoat The abrasion resistant coating shall be applied to pipes which have been coated with fusion bonded epoxy according to COMPANY specification Inspection and Cleaning If the pipes are moved or handled between coats, then they shall be visually examined for dents, laps, defective bevels, damage to the coating and other obvious defects in order to avoid coating unusable pipe. CONTRACTOR shall record the pipe numbers of the defective pipes, mark the pipes and remove them from the stack to be coated. Salts and dirt shall be removed. Organic contaminants shall be removed Anodes, bevels and "cutback" areas described in Section 5.2 shall be masked to prevent overspray. Any coating or overspray which is inadvertently deposited on these areas must be removed Abrasive Cleaning The fusion bonded epoxy coating shall be roughened by light sweep blasting over the area to be coated with the abrasion resistant coating. Before sweep blasting, each joint of pipe shall be uniformly dried to completely remove all moisture and to prevent any condensation of moisture on the pipe. FBE coated pipe temperatures shall be at least 5º F above the dew point. Ends of the pipe shall be protected with plugs that prevent entry of abrasive into the pipe interior during blasting. Any abrasive entering the pipe shall be removed prior to coating. The blasting shall be done with a virgin abrasive mix described in CONTRACTOR's approved work plan. To remove all dirt, mill scale, rust, corrosion products, oxides, paint and other foreign matters. The surface shall have a uniform appearance; very light shadows, streaks or discolorations may be considered acceptable; however, at least 95% of the surface shall have a uniform light cleaned non lustrous surface. The compressed air for blasting shall be free of water and oil. Adequate separators, filters, or traps shall be provided. The blasting media working mix shall be selected to produce an anchor pattern profile of not less than 2.0 mils nor more than 4.0 mils. This blasting shall not remove more than 4 mils from the area to be coated with the anti abrasion coating and shall not remove any significant amount of coating Specification for Material and Application of Abrasive Resistant Coating on Steel Line Pipe 8 of 17

9 from the half of the pipe which is left exposed. The blast shall be directed more or less in the direction of the center of the 120 degree arc of the pipe that will receive the full thickness, leaving the 15 degrees on both sides as a transition area. CONTRACTOR shall remove any abrasive remains left in the pipe after blasting. For consistent surface finish and anchor pattern a stabilized abrasive working mix shall be maintained by frequent small additions of new grit (dry sand or steel) commensurate with abrasive consumption. Infrequent large additions shall be avoided. The abrasive working mix shall be maintained clear of contaminants by continuous effective operation of blasting machine scalping and air wash separators. Anchor patterns will be verified by the CONTRACTOR by taking anchor patterns on both ends of the first ten (10) joints blasted. Thereafter, tests will be conducted on both ends of every twenty fifth (25) joints. The test must be conducted with Istex Presso Film or equivalent and measured with the appropriate gauge. The COMPANY Representative shall maintain the test results and include them with inspection reports Final Surface Preparation The area where the pipe leaves the cleaning station after sweep blasting shall be well illuminated (500 lux) to permit visual inspection of the condition of the cleaned surfaces to locate defects. The blastcleaned surface shall not be contaminated with dirt, dust, metal particles, oil, water, or any other foreign matter from any source, nor shall the anchor pattern be destroyed or burnished by pipe transport systems, processing equipment, tools, or follow up cleaning with abrasive sanders. Following abrasive cleaning and prior to coating application, all dust, or other loose contaminants remaining on the surface or entering the interior of the pipe shall be blown off with clean, dry, oil free compressed air in a manner not affecting the other clean pipe or pipe to be coated. When compressed air cleaning facilities are not available, vacuum cleaning or other suitable methods may be used. Any pipe not coated within two hours after blasting, if the dew point is less than 50º F, shall be reblasted. In addition, any pipe not coated within 30 minutes after blasting, if the dew point is greater than or equal to 50º F, shall be reblasted. An anchor pattern removed by excessive grinding, will be reblasted before coating. Determination of what constitutes excessive grinding is to be made by COMPANY s authorized representative. Typically any continuous ground area of more than 0.5 square feet or a total ground area of more than 2 square feet per joint will be considered excessive. If the anchor pattern is destroyed, the ground areas shall be checked by ultrasonic testing to ensure that the remaining thickness exceeds the minimum required in accordance with COMPANY specification PS The surface condition of the material shall be approved by the COMPANY s Representative prior to the application of the coating. Pipe surfaces not acceptable by the COMPANY s Representative for coating will be recleaned at no extra cost to the COMPANY. When required by the COMPANY, the material will be subjected to an external acid wash after blasting but prior to coating. Prior to the commencement of the coating, the CONTRACTOR shall furnish the COMPANY, for review and approval, detailed procedures and specifications regarding the actual acid wash operations the CONTRACTOR proposes to utilize for the job. 6.3 COATING APPLICATION General CONTRACTOR shall be familiar with and strictly follow the coating manufacturer s specifications and recommendations for the application, curing Specification for Material and Application of Abrasive Resistant Coating on Steel Line Pipe 9 of 17

10 temperatures and curing time for the fusion bonded epoxy system used. If required by COMPANY, CONTRACTOR shall work with the manufacturer and/or his representative to eliminate any difficulties that might arise in the application of the coating. The coating shall be sprayed to the nominal thickness in Section 5.3 and CONTRACTOR's approved work plan described in Section The CONTRACTOR shall give particular care and attention to keeping the pipe and the coating dry during application Equipment CONTRACTOR shall provide spare equipment (pumps, nozzles, etc.) to ensure production is continuous and no breakdowns occur due to equipment cleaning or repairing. Coating shall be applied with equipment which conforms to the coating manufacturer's recommendations for humidity, and dew point temperature and CONTRACTOR's approved work plan described in Section Multiple Coats The CONTRACTOR shall not allow more than the coating manufacturers recommended maximum time to lapse between coats. CONTRACTOR shall cover or shelter the pipes to prevent rain or mist from settling between coats. If more time does lapse, the COMPANY may, at COMPANY's option require CONTRACTOR to remove the coating or to sweep blast the surface according to Section Curing The coating shall be cured according to the manufacturer's recommendation. It will be the responsibility of the coating applicator to take immediate corrective measures when conditions exist which adversely affect the external coating operation with respect to cleaning, application or material performance. NOTE: Temperature at the coating station and post application curing time shall be closely monitored to comply with the limits set by the coating manufacturer. A best temperature and cure time can usually be determined after the first few joints are coated Marking If the paint stenciled pipe markings applied at the pipe mill are removed in the coating process, CONTRACTOR shall record the markings and paint stencil them on the inside surface of the pipe after coating. Paint markings shall be weather and sunlight resistant End Caps/Bevel Protectors If bevel protectors were removed to install pipe caps, CONTRACTOR shall re install them before shipping or storing the pipe. 6.4 IN PROCESS INSPECTION AND TESTING COMPANY Inspection COMPANY shall have full and free access to every part of the coating yard and the on/off loading facilities of CONTRACTOR to inspect the coating materials, equipment, and CONTRACTOR s work. CONTRACTOR shall provide reasonable assistance to COMPANY at every stage of inspection. COMPANY reserves the right to inspect the work but is in no manner obligated to supervise the work CONTRACTOR Inspection and Testing CONTRACTOR shall furnish all material, equipment, and qualified personnel to perform the examinations and testing specified herein.

CONTRACTOR shall visually inspect the integrity and uniformity of all of the coating on each pipe. Discontinuities or abnormalities shall be circled with a waterproof marker. Markings shall be far enough from the imperfection or damaged area to allow surface preparation and patching to take place without obliterating the markings. The area shall be repaired using a method described in CONTRACTOR's approved work plan (see Section 4.3.1) Thickness Measurements Dry coating thickness shall be measured with a properly calibrated Mikrotest magnetic film thickness gauge, or equivalent, to ensure finished coated pipe has a minimum dry film thickness of 100 mils including FBE coating. The film thickness gauge shall be calibrated at a minimum of once every four hours against the coated substrate standard for 100 mils thickness, as defined by the U.S. Department of Commerce, National Bureau of Standards, Certified Coating Thickness Calibration Standards for Non Magnetic Coating of Steel. Six measurements of the dry film thickness shall be made on each pipe using a coating thickness gauge described in CONTRACTOR's approved work plan of Section Two measurements shall be taken within three feet of each end and two shall be taken within three feet of the center of the pipe. Measurements shall include one measurement on the center of coated when full thickness and one measurement approximately 1/8 of the pipe circumference beyond this area. If the coating thickness varies enough to be visually detected, then each pair of measurements shall include one at a high spot and one at a low spot in the coating. The measurements shall confirm that the combined thickness of both layers is within allowable limits determined as follows. Minimum Thickness: 100 mils (including FBE) Maximum Thickness: 150 mils (including FBE) Holiday Detector CONTRACTOR shall furnish, maintain, and operate a high voltage holiday detector of a type acceptable to COMPANY and shall locate and repair all holidays and damaged spots. The entire coated surface area shall be checked for holidays. CONTRACTOR shall furnish COMPANY a certification from the manufacturer of the holiday detector or from a testing agency acceptable to COMPANY that the unit has been properly adjusted and the voltage set within that range which is necessary for the detection of holidays in the type coating applied in accordance with this Specification. The adjusting mechanism shall be sealed. The holiday detector shall be checked and recalibrated, if necessary, every four (4) hours with an accurate D.C. voltage meter furnished by CONTRACTOR and by use on a control coated pipe with known holidays The search electrode shall be steel spring, wet sponge or conductive rubber CONTRACTOR shall test all coating applications immediately after coating for holidays, pinholes and discontinuities. Testing for coating flaws shall be in accordance with the latest edition of NACE RP 02. Minimum voltage shall never be less than 125 volts per mil of coating thickness All holidays and other coating defects shall be marked with non grease type markers and the number and types of holidays recorded for each pipe joint Any joint of pipe with unacceptable, unbonded, or non adherent coating and pipe with excessive damaged coating and/or holidays in excess of 10 per 40 feet joint length, shall be rejected and reblasted and recoated.

12 Patching repair limits will be based on 1 holiday per each foot of length with a maximum of 10 holidays for an average 40 foot joint and 13 holidays for an average 60 foot joint. Repetitious holiday counts near maximum shall be cause for rejection. In all cases, COMPANY s authorized representative, shall make the final acceptance/rejections determination In the event the specified dry mil average is not of sufficient thickness to prevent more than the maximum allowable holidays per 40 foot joint of pipe, then it will be the responsibility of the coating applicator to increase the thickness sufficiently to meet the specified maximum allowable holiday requirement. This increase in coating thickness and extra expense will be done only with authorization of the COMPANY s Representative Coated pipe requiring closer inspection of cured coating film by COMPANY s Representative shall be set aside at no additional cost Laboratory analysis of coating materials shall be conducted for each batch (or lot) at the COMPANY s discretion When requested, applicator shall furnish sufficient amount of cured coating to allow the COMPANY to perform infra red scans and/or Differential Scanning Calorimeter (DSC) to determine conformance with manufacturer s specifications Ring Samples A coated sample 12 in length shall be cut from the end of a joint of pipe, labeled by coating date, joint number, and batch number. The cleaning, heating, and application history shall also be included.
