Sixty years, architects have been made of stainless steel to build cost-effective permanent structures. Many of the existing buildings fully explained this choice is correct. Some are very ornamental in 304 stainless steel, such as Chrysler Building in New York City. But in many other applications, the role of stainless steel is not so dramatic, but it plays an important role in the aesthetics and performance of buildings. For example, when stainless steel is more due to wear and resistance to indentation than other metal materials of stainless steel pipes of the same thickness, so the construction of sidewalks in the turnover rate of the local population, it is the material of choice for designers. And appearance quality A, according to GB14975-2002 "stainless steel seamless pipe" provides the length of pipe is usually (not length) hot-rolled steel 1.5 ~ 10m, hot extruded pipe is equal to and greater than 1m. Cold drawn (rolled) pipe wall thickness 0.5 ~ 1.0mm were, 1.0 ~ 7m; wall thickness greater than 1.0mm were, 1.5 ~ 8m. Such can be divided into stainless steel seamless pipe and welded stainless steel pipe (pipe joints) into two categories, according to different manufacturing processes can be stainless steel tube: hot-rolled, extruded, cold drawn and cold rolled it several basic types, Press the cross-sectional shape can be divided into tube and shaped tubes, round steel widely used, but there are some square, rectangular, semi-circular, hexagonal, equilateral triangle, octagonal shaped stainless steel. For withstand fluid pressure hydraulic pipe must withstand the test of capacity and quality, leakage does not occur at a predetermined pressure, wet or expansion of qualified decorative stainless steel pipe, steel pipe but also according to some standard or demand side curling test, flaring test, flattening test. Seamless stainless steel pipe, also known as stainless steel seamless pipe, steel ingot is made of perforated or solid through the capillary tube, and then by the hot-rolled, cold-rolled or cold call is made. Seamless steel pipe wall thickness specifications mm diameter * number indicates.
