Astm A269 A249 Small Size Stainless Steel Pipe Boiler Round Tube Piping

Stainless steel precision tube surface treatment is more stringent than ordinary stainless steel tube.
The surface of the precision stainless steel tube has the following requirements: the surface of the tube body is free from scratches and scars; The wall thickness is uniform and smooth, and the pipe mouth is complete without burrs; The inner wall is smooth, and there is no leakage welding sand hole at the weld.
Usually, the surface of ordinary pipe is rough and needs to be treated twice. In the appearance of the advantage than ordinary stainless steel well more than a little bit.

Ordinary stainless steel pipe commonly used material is generally 201, slightly requirements will use 304,316L almost rarely used.

The commonly used material of stainless steel precision tube is generally 304 and 316L, which is more prominent than ordinary stainless steel tube in material performance. In addition to the precision stainless steel pipe factory before, need to go through a number of mechanical properties test, such as: hardness test, bending test, compressive strength test and so on. In the late machining performance is often better than ordinary pipe.
