Tubing Stainless Steel 316

316 stainless steel tubing is a hollow round steel, mainly used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial tubinglines, as well as mechanical structural components. In addition, the bending, torsional strength of the same, light weight, it is also widely used in the manufacture of mechanical parts and engineering structures. Also used for the production of various conventional weapons, barrels, shells and so on.


Stainless steel tubing is a hollow round steel, mainly used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial tubinglines and mechanical components. In addition, the bending, torsional strength of the same, light weight, it is also widely used in the manufacture of mechanical parts and engineering structures. Also used for the production of various conventional weapons, barrels, shells and so on. This type of steel tubing can be divided into stainless steel tubing and stainless steel welded tubing (with seam tubing) two categories, according to the different manufacturing process can be divided into: hot rolling, extrusion, cold and cold rolling of these basic types, according to sectional shape can be divided into circular tubings and special-shaped tubings, widely used is a circular steel tubing, but also some square, rectangular, semi-circular, hexagonal , equilateral, octagonal and other profiled stainless steel tubing.


To withstand the fluid pressure of the steel tubing are to carry out hydraulic test to test its pressure-resistant capacity and quality, under the prescribed pressure does not occur leakage, wetting or expansion for qualified, some steel tubings should be based on the standard or demand-side test, expansion test, flattening test.


Seamless stainless steel tubing is also known as stainless steel seamless tubing, is made of ingot or solid tubing through piercing into the capillary, and then by hot rolling, cold rolling or cold dial made. The specification of seamless steel tubings is indicated by the diameter of the wall thickness mm.

 

316 stainless steel has good welding performance. All standard welding methods can be used for welding. Welding can be used according to use, respectively, using 316Cb, 316L or 309Cb stainless steel filler rods or electrodes for welding. In order to obtain the best corrosion resistance, the welding section of 316 stainless steel needs to be welded back fire treatment. If 316L stainless steel is used, no soldering back fire treatment is required.
