A554 201 Round Polished Welded Stainless Steel Pipe Corrosion Resistant

ASTM A554 201 Corrosion Resistant Round Polished Welded Stainless Steel Pipe For Construction Industry

Classification of stainless steel pipe: stainless steel seamless steel pipe and stainless steel welded steel pipe (seam steel pipe) basic two categories. According to the outer diameter shape of steel tube can be divided into round tube and special-shaped tube, what is widely used is circular steel tube, but also have a few square, rectangle, semicircle, hexagonal, equilateral triangle, octagonal special-shaped steel tube.

For the steel pipe under fluid pressure to carry out hydraulic test and ray flaw detection to test its pressure ability and quality, under the specified pressure does not leak, wet or expansion for qualified, some steel pipe according to the standard or the requirements of the side test, flaring test, flattening test.

Seamless stainless steel tube, also known as seamless stainless steel tube, is made of steel ingot or solid tube blank by perforation of wool tube, and then made by hot rolling, cold rolling or cold dialing. The specifications of seamless steel pipe are expressed by the number of millimeters of outer diameter * wall thickness.

304 stainless steel tube full name SUS304 stainless steel tube.

SUS304 stainless steel pipe belongs to the American brand of stainless steel pipe material, domestic brand is equivalent to 0Cr19Ni9 stainless steel pipe, usually replaced by 0Cr18Ni9.

The mechanism of stainless steel rust prevention is the formation of dense oxide film alloy elements, isolated oxygen contact, prevent continued oxidation. So stainless steel is not "rust free
