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 nature, such as New York City's Chrysler Building. 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. Such as stainless steel pipes, stainless steel is more due to wear and pressure marks than other metal materials of the same thickness, so the turnover rate of the local population during the construction of the sidewalk 316l stainless steel pipe, which is the material of choice for designers. Straights allow depth. Hot-rolled, hot extruded steel tube, 140mm in diameter and is equal to not more than 5% of the nominal wall thickness of decorative stainless steel pipe, the maximum depth of less than 0.5mm; cold drawn (rolled) steel is not greater than the nominal wall thickness of 4% stainless steel pipe, The maximum depth of not more than 0.3mm. E, both ends of the pipe should be cut at right angles, and clear the glitch. Hot (hot extrusion) 54 ~ 480mm total of 45 kinds of steel pipe diameter; wall thickness of 4.5 ~ 45mm total of 36 species. Cold drawn (rolled) steel pipe diameter 6 ~ 200mm total of 65 species; wall thickness of 0.5 ~ 21mm total of 39 species. C, inside and outside surfaces of steel pipes shall not have cracks, folding, crack, crack, rolled off, there is separation and scarring defects, these defects should be completely removed (except for tube machining), outside the wall and not after clearing diameter than the negative deviation. Whoever does not exceed the allowable negative deviation of the other minor surface defects do not cleared. 316l stainless steel pipe stainless steel pipe _ _ Shengda-commerce provided by Tianjin Bao Bao Jie Shengda Trading Company.
