TECHNICAL SHEET FOR I.P.S. PIPES AND THREADED FITTINGS 1. Components of I.P.S. raw materials I.P.S. threaded fittings are manufactured with high molecular homopolymer polypropylene (H-PP). This material was especially chosen for it confers grater resistance on products subjected to high temperature pressures and for the hardness of thread which it gives to the fittings. This raw material presents the following main characteristics: 1.1 Chemical resistance The H-PP is a polyolefinic polymer that features a high molecular weight, therefore it is more resistant to chemicals and other products (such as acid or basic substances, like lime or cement for instance) with which it may be in contact Our technical department has a complete list of chemical resistance to different products according to international standards. 1.2 Resistance to stray currents Like most thermoplastic products, H-PP is a poor electrical conductor. 1.3 Soundproofness The elasticity of H-PP makes possible to absorb and eliminate almost all the vibrations that normally occur in iron pipes. It is therefore highly soundproof at no extra cost. 1.4 Low thermal conductivity H-PP low thermal conductivity (0.22 W/ m K) (0.19 Kcal/m C) reduces the heat dispersion of the fluid that it conveys. Further, it decreases the condensation which normally forms itself on the outside of metal pipes under specific hygrometric conditions.
1.5 Low pressure loss The inside surface of H-PP pipes is rather smooth and presents few irregularities (0.0070 u) which entails a reduction in pressure loss. As a consequence limestone cannot build inside the pipe. 1.6 No toxicity The raw material used for the production of IPS Threaded System is absolutely non toxic and complies with current national and international regulations. 1.7 Easy workability The IPS Threaded System consists in a complete and integral system for the conduction of fluids. It includes seat valves, threading tools, taps, minivalves, crossover pipes, flanges with gaskets, sealer and almost 30 different types of fittings. Following our installation recommendations you can be sure to reduce completely the probability of human factor mistakes. Scopes and Advantages of I.P.S. threaded system I.P.S. Threaded System products were design to convey pressurized hot and cold water, for the following uses: -Sanitary systems -Heating and air-conditioning systems Besides it can also be used for: -Compressed air installations -Watering systems for green-houses and gardens -Transporting liquid stuff -Industrial applications This system includes all the necessary parts to realize a complete installation from the beginning to the end. I.P.S. Threaded System puts an end to corrosion problems since it is made with corrosion resistant material. It has a wide range of application, due to its high temperature pressure resistance. High resistance to chemical agents, which makes it apt for the flowing of liquids with aggressive agent contents.(according to chemical tables provided by the producer).
It is made with opaque polypropylene, it is a non-pollution material on which algae cannot develop. It is recyclable with no risk of air pollution. It is therefore environment friendly. It is not attacked either by galvanic currents nor by parasitic currents. It does not transmit smell nor flavour to the conveyed liquid Ensuring the long working life of your piping system Using the I.P.S. Threaded System you can be sure that you are installing materials in which the producer guarantees at least 50 years of constant use. That is possible because we are sure about our raw materials and because we use special additives that avoid ageing in thermoplastics. I.P.S. s raw materials is mixed with the following additives: - IRGANOX, non-toxic stabilizer which preserves the product against premature ageing due to high temperatures - ANTI UV CIBA- GEIGY, compound which prolongs the effective life of the piping installation exposed to sun rays. 2. Physical Characteristic of I.P.S. s raw material Density: 0.902 g/cm3 / 0.0012 lb/ cubic inch Modulus of Elasticity: 15.000 N/mm2 Vicat softening point: 150 C / 302 F Lineal coefficient of expansion: 0.11 mm/m C Tensile Strength at yield point: 330 N/mm2 3. Products of the I.P.S. Threaded System
I.P.S. 4x4: It s an H-PP four layers pipe produced by our exclusive method of coextrusion, where we concentrate the properties provided by the additives where we exactly need them. For example: The inner layer has anti-oxidant additives to prevent premature ageing and to ensure a non-toxic channel for the conveyed fluid during the whole service life of the system. The outer layer has anti-uv additives to protect the pipe against solar exposure. I.P.S. 4x4 PLUS: It s the same H-PP four layer pipe, but with adding of an external thermoplastic foamy layer. This outer layer is co-extruded with the pipe and it gives to the 4x4 PLUS excellent thermal properties. For example: Coefficient of thermal conductivity of H-PP K= 0.19 Kcal/m C Coefficient of thermal conductivity of the foam K= 0.054 Kcal/m C Coefficient of thermal conductivity of a 4x4 Plus of ¾ K= 0.036 Kcal/m C Fittings: I.P.S. Threaded System offers almost 30 different types of fittings, produced by moulded inyection, with the same H-PP. Fittings with metallic insert: We also provide fittings with bronze-nickel inserts for the connection of taps or to provide the connection between threaded system and fusion system. 4. Mechanical Characteristics 4.1 Traction resistance The H-PP provides to the whole I.P.S Threaded System excellent properties for the traction resistance, specially on the threads. The higher Modulus of Elasticity of the H-PP, comparing it with other thermoplastics, confers to the I.P.S. products proper resistance to tractive stress. The threads of our system supports even stresses of 1500 kg / 3304 lb. This property ensures a tight union between pipe and fitting even at high temperatures and pressures.
4.2 Thermal Conductivity The H-PP has a very low thermal conductivity coefficient (0.22 W/m C / 0.19 Kcal/m C) or ( 0.0055 W/inch F / 0.0048 Kcal/inch F). This property provides economic advantages because you can save gas and electricity. You also ensure more comfort because you can have hot water in less time at the shower of your bathroom. With cold water, the H-PP avoids condensation on the external wall of the pipes during special hygrometric conditions. As a reference: Thermal conductivity of the copper K= 330 W/m C / 8.38 W/inch F 5. Quality Controls The products of the I.P.S. Threaded System are constantly tested according to National and international Standards. Tests during production: DIMENSIONAL TEST: The Quality Laboratory controls the dimension of the pipes at each hour of the day. They measure external diameter and wall thickness ensuring that the values are inside the standards of ISO, DIN and IRAM. The fittings are also tested so that they can accomplish standards of conic threads B.S.P.T. Withworth (ISO 7/1 Rc.) IMPACT TEST: Different samples of pipes are tested at 23 C for the impact of a standardized weight to see if they have proper mechanical resistance. This test is accomplished 3 times a day. PRESSURE TEST: The fittings are tested to the Hoop Stress Test giving them 65 kg/cm2 / 943 psi during one hour. TIGHT TEST: The unions of the fittings are tested so that with 25 kg/cm2 / 363 psi during one hour, they don t have to present leakage. DIMENSIONAL STABILITY: The samples of pipes and fittings are stabilized at 132 C / 269 F during two hours, and after cooling up to environment temperature, the Quality control laboratory test the dimensional parameters. By this test we control the pipes response to high temperatures and their linear expansion.
AGEING TEST: To be able to guarantee our products for at least 50 years we accomplish an extremely accurate test according to international standards. We put our pipes and fittings under severe temperature and pressure conditions during 1000 hs, that represent the constant normal use during 50 years. For example, for our 4x4: Test temperature: 95 C / 203 F Internal constant pressure: 15 kg/cm2 / 217.8 psi Test Time: 1000 hours RANGES OF APPLICATION ACCORDING TO DIN NORMS (with an effective life guarantee of 50 years) Temperature Years PN 10 20ºC/68 ºF 50 9.9 kg/cm2 143.7 psi 40ºC/104 ºF 50 7.0 kg/cm2-101.6 psi 60ºC/140 ºF 50 4.7 kg/cm2-68.2 psi 80ºC/176 ºF 25 2.3 kg/cm2-33.4 psi These ranges are established considering continuous use. In practice, when this use is not constant, its effective life is even longer.
Recommendations for a correct installation of IPS Threaded System Tools needed -Threading tool -Pipe cutter -IPS PLUS (Thread sealer with hemp) -Cutter -Hemp (for diameters bigger than 1 ¼ ) Steps for a correct installation 1) Cut the pipe with a Pipe Cutter in a perpendicular way from the axis of the pipe. 2) Take out carefully with a cutter the loosen plastic material product of the cut. 3) Introduce the threading tool in one of the edges of the pipe using the guide so that the tool reaches the border of the pipe in a perpendicular way. 4)Start threading clockwise making a little pressure over the border of the pipe. 5) Use your threading tool only just up to the metallic border of the tool. It's important to accomplish this advice, a deeper thread can produce leakage. 6) Turn the tool anti-clockwise and take out the loosen plastic material. Be sure to make a tidy work using a cutter. 7) Put the IPS PLUS sealer all over the thread of the pipe. 8) Connect the needed fitting turning it round clockwise. 9) Be sure to reach up to the top of the thread. 10) Remove the remaining sealer with your finger. 11) For diameters bigger than 1 ¼ you may use some hemp putting it clockwise inside the valleys of the trhead Important advices a) Our IPS PLUS sealer is designed also for high temperatures. b) For external piping systems you have to follow the producer's recommendations to avoid linear expansion problems. There are different solutions according to the environment temperature and the working temperature (hot water) -Holder batts - Fixed points - Changes of direction to compensate thermal expansion c) For outdoors piping systems you have to cover the pipes and fittings with UV Proof Tape (IPSolar) to avoid degradation of the plastic material. d) You may cover with paper your IPS Threaded System inside walls to allow linear expansion with lower stress. e) In connecting IPS Threaded System with metallic pipes you may use IPS fittings with metallic inserts.
