Steel pipe fittings is a long hollow section steel, a large number of channels for transporting fluids such as oil, gas, water, gas, steam, etc. In addition, practice bending, torsional strength of the same lightweight, so it is widely used in manufacturing mechanical parts and engineering structures. Also used in producing all kinds of conventional weapons, the barrel, shells and so on.
Stainless steel pipe fittings Classification: Seamless and welded steel pipe points (pipe joints) two categories. By cross-section shape can be divided into tube and shaped tubes, round steel is widely used, but there are some square, rectangular, semi-circular, hexagon, equilateral triangle, octagon and other special-shaped pipe.
For the steel pipe to withstand fluid pressure test should be conducted to test the pressure of hydraulic capacity and quality, the provision does not leak under pressure, wet or expansion of qualified, some steel but also according to the requirements of the standard or demand side, curling test, flaring test, flattening tests.
Seamless: Seamless steel pipe or solid steel ingot is made of the capillary tube by the piercing, and then by hot rolling, cold rolling or cold call is made. Specifications of seamless steel pipe with outer diameter * thickness mm numbers. Hot-rolled and cold rolled seamless steel pipe points (allocated) seamless two.
Hot-rolled seamless steel tube sub-normal, low, medium pressure boiler pipe, high pressure boiler steel pipe, steel pipe, stainless steel pipe fittings, oil cracking pipe, steel and other steel and other geological.
Cold (allocated) Subject to sub-normal seamless steel pipe, low and medium pressure boiler pipe, high pressure boiler steel pipe, steel pipe, stainless steel pipe fittings, oil cracking pipe, other steel, but also including Carbon Steel Tube, Alloy Thin steel, stainless steel thin-walled steel pipe, shaped steel.
Hot rolled seamless tube outer diameter generally greater than 32mm, wall thickness 2.5-75mm, cold-rolled seamless steel pipe diameter can go to the Department 6mm, wall thickness can be 0.25mm, outer diameter thin-walled tube to 5mm thickness can be less than 0.25mm, cold than hot-rolled high dimensional accuracy.
Stainless steel pipe fittings with the social and economic development, its application has also been more widely popular. Will certainly bring a new change in all areas.
