Steel and malleable cast iron pipe fittings with threaded connections, if the working pressure is higher (but within 1.6Mpa), steel pipe fittings may be used. Stainless steel pipe Fittings Standard should include the standard of type parameters and stainless steel pipe fittings material standard. However, the material standard or the stipulation is incomplete, or lacks the quality technical requirement such as the order request, the inspection and the group batch rule, the quality proof and so on. Stainless Steel pipe fittings Material standard matching poor, often from their own standpoint, angle, rather than from the pressure piping throughout the standard system set out. The selection of the engineering, pipe standards have, but no corresponding forgings or castings standard. Water supply cast iron pipe fittings are cast by gray cast iron, water supply cast iron fittings have socket-type and flange-type two kinds, its use is similar to malleable cast pipes, with the following types: Cross Tube, T-tube (including three-bearing cross pipe, three-plate cross pipe, four-bearing cross pipe, four-plate cross pipe, double-bearing-T-tube, double-plate-shaped tube, three-bearing T-tube, three-plate-t-tube, double-bearing single-plate-t-tube, Tan Cheng Two-disc-T-tube, 90° bend tube, 45° bend pipe, fork tube, pipe for fire hydrant, casing and so on. Drainage cast iron pipe fittings are mainly socket bending pipe, 90° elbow, 45°y-shaped tee, 90°t-shaped tee, 90°ty-shaped tee, four-pass, four-way, Ty-shaped three-way, reducer four-pass, pipe hoop, T-shaped mouth tee, 45° elbow, Y-shaped reducer tee, socket cleaning mouth, s-shaped water bends, p-shape, floor drain and other varieties. Note: A variety of different joint fittings can be made of different materials, at present, plastic joint pipe has been widely used, because only the material is different, here will no longer repeat. The reality is stainless steel pipe forgings standard to borrow pressure vessel forgings Standard, did not consider the differences between the two, such as welding, film inspection and other provisions. Steel pipe fittings made of carbon steel, commonly known as wrought iron pipe fittings. It has good weldability and can be used in places where welding is required, such as steel pipe clamps are often used in boilers or water tanks and other steel equipment. The type test standard of stainless steel pipe fittings, only GB12459 and GB13401 standards stipulate the pressure calculation of the blasting test of steel butt welded seamless stainless steel pipe fittings and steel steel pipe fittings, and other type test standards or standards of implementation that ensure the quality of pipe fittings. Steel metal stainless steel pipe fittings In order to meet the different uses and conditions, the structure of threaded fittings is varied. The most used are elbows, tee and reducer.
we have our own pipe fitting factory since 1998 ,which covers 100 acres. In 1998, we invested and set up a new flange factory. Up to now, we have a complete production system, and become a professional and competitive group in this field.
