GI Fittings Pipe Back Nut Maximum Pressure: - 25 BAR (363PSI) (2.5MPA) CLASS 150 Maximum Temperature: - 200°C (392°F) Tensile Strength: - 350MPA Suitable Applications: - Water, Oil, Gas, Petro-Chemical Product Description Our company’s products are divided into three types by type: heavy, medium and light ， According to the surface treatment, there are three types. Galvanized,electro-galvanized and black.The backnut is able to prevent self-loosening of the fittings. This is a common problem with older pipelines that need replacement. Product Parameters Standard: - EN10242 / ANSI / ASME B16.3 / DIN2950 / IS0 49 / NBR6943 / IS1879 / BS EN10242 Threaded Standard: - EN10226 / ASME B.1.20.1 / DIN2999 / ISO7-1 / ISO228 / IS554 / BS EN10226 Work Pressures： - PN25 / 2.5Mpa / 363PSI /CLASS 150 / 25Bar Certification： - UL Listed /FM Approved /CE /ABNT /TSE /SNI /ISI Elbow is mainly used to connect two equal diameter pipes perpendicular to each other at the right angle bend of the pipe, and the different diameter elbow is connected with two different diameters perpendicular to each other, so that the vertical pipes can be effectively and reasonably linked together. Technical Data Maximum Pressure: - 25 BAR (363PSI) (2.5MPA) CLASS 150 Maximum Temperature: - 200°C (392°F) Tensile Strength: - 350MPA Hardness: - HB150 (Brinell) Elongation Rate: - 10% Suitable Applications: - Water, Oil, Gas, Petro-Chemical Material: - Malleable Iron
