Quality Analysis of Bright Annealed Stainless Thin-walled Welded Pipe Steel Tubing

SUS304 (0Cr18Ni9) austenitic stainless steel material is used for stainless steel thin-walled welded pipe, and the strip thickness is 0.20mm. After forming, the billet pipe is welded, and then the tube is reduced and stretched for many times. After cleaning and drying, the tube is annealed brightly (solution treatment). The thin-walled stainless steel pipe is made of SUS304 (0Cr18Ni9) austenitic stainless steel with a thickness of 0.20mm. After forming, the billet pipe is welded and stretched for several times. After cleaning and drying, the pipe is annealed brightly.

The annealing of stainless steel thin-walled welded pipe adopts advanced gas shielded bright annealing furnace equipment. Its furnace structure is linear continuous, novel and unique. In order to prevent oxidation of the pipe and the increasing of the carbon during annealing, decomposing ammonia gas is fed into furnace and stainless steel pipe for combustion protection. The heating temperature is 1050 C. Stainless steel pipes are heated and cooled rapidly to obtain annealed stainless steel pipes. Bright annealed stainless steel pipes have uniform single-phase austenite structure with bright surface and no oxidation.
In the production of bright annealed stainless steel pipes, some quality problems are prone to occur during annealing due to the influence of production management, operation, process technology and other factors
