Brief description of the performance characteristics of Thin Wall Stainless Steel Tubing
Nov 03, 2018

The so-called Thin Wall Stainless Steel Tubing mainly refers to a stainless steel pipe with a wall thickness and an outer diameter ratio of less than 6%. At present, the building water supply Thin Wall Stainless Steel Tubing and pipe fittings contain more than 12% chromium, and iron alloys with austenite crystal structure properties formed by other metal elements are added as needed. The addition of nickel improves the ductility and toughness of the material, making the process easy to form and bending.

 

At the same time, in the process of processing the Thin Wall Stainless Steel Tubing, proper control of the carbon content can improve the welding performance of the material. The addition of molybdenum or manganese can improve the pitting and seizure resistance of the material. The reaction of chromium in the tube with oxygen and oxidant produces a passivation effect, forming a thin and tough dense passivation film Cr2O3 on the surface, which acts as a protective coating against corrosion.

 

The thin-walled stainless steel tube is treated by polishing, polishing, etc., which not only eliminates surface defects, but also makes the passivation film more delicate and dense to reduce the probability of pitting corrosion. At the same time, the inner wall of the pipe is smooth and the friction is small, which further improves the hydraulic performance of the pipe and saves consumption.
