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,vas 5054a 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,tacho universal flattening tests.
304stainless steel pipe fittings steel tensile strength is 2 times that of copper tube 3 to 4 times, plastic pipe 8 to 10 times. Strength of the material determines whether the strong water crashworthiness, safety and reliability. The safe and reliable water in construction to the most important requirements. In the case of bmw ops being blunt, stainless steel pipe leakage is very unlikely, while the copper and plastic pipes relatively high leakage rate, pipeline construction or re-decoration easily damaged. Several major cities in the domestic residence on the main complaint is the plastic water pipe leak, a major cause of leaks in plastic pipes stand up to physical shock.
High-rise water supply system working pressure is generally higher than 0.6Mpa; require a higher pressure on the pipe. Plastic pipe used in water system pressure are smaller than this value can not be competent; composite pipe expansion key programmer coefficient difference between the two materials large, such as bonding is not strong or easy to produce large temperature separation; thin brass pressure up to 5.9Mpa; and thin-walled stainless steel pipe fittings as excellent mechanical properties, can withstand high water pressure up to 10Mpa above, particularly suitable for high-rise water supply.
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,hookah 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 and carbon steel with the same generally vertical, vertical curved or curved continuous casting machine. The refined molten steel into the ladle. After turret will be pouring ladle to the tundish injection port at the top, and then injected into molten steel through a long nozzle to the tundish. Tundish molten steel through the submerged nozzle into the mold and condensation forming and continuous downward. Solidification of the slab surface after the second paragraph to rapid cooling to the cold heart into a solid billet after the cut-flame cutting, thus completing the entire casting process.
