Credibility ,Bright annealing tube under a reducing atmosphere or in a vacuum protection, after high temperature solid melting and rapid cooling to get the stainless steel tube, requiring the inner surface has a very good surface roughness and cleanliness, is a comprehensive consideration of organizational stability corrosion resistance and workability of the pipe.
Bright annealed tube inner surface roughness Ra values and their own cleanliness is extremely demanding, so the particles can occur during transport and accumulation of fluid retention has been effectively curbed. In addition, the chemical composition of the pipe and the base material dimensional tolerances need to be strictly controlled to ensure the weldability of steel and the welding quality in the welding fumes, which can reduce the occurrence of particle generation and improving the corrosion resistance of welded parts, and smoothness.
Bright annealing tube production control:
The material of the stainless steel round bar is from Jiuli and Baosteel China, we control the quality from the very start. We polished three times to make sure the surface is perfect bright and smooth, and without any deficiency in quality. We have precision equipment to test according to the standard required and PMI test to check the material before delivery.
