Stainless Steel Sanitary Tube

Stainless Steel Sanitary Tube
ASTM A270/EN10357/DIN11850

Our stainless steel sanitary tube complies with ASTM A270 standards. Crafted from cold-rolled stainless steel strip, its chemical composition is meticulously controlled to improve weldability. The resulting weld bead undergoes cold-working to achieve a seamless finish, rendering the longitudinal weld nearly imperceptible. Subsequent bright annealing in a carefully controlled environment preserves the tubing's structural integrity at its maximum

Manufacture Processes




The Bright Annealing process in Vinmay  is performed in a controlled atmosphere containing inert hydrogen gas at 1040℃. Annealing is a typically used to reduce hardness , increase ductility and eliminate internal stresses.While the controlled atmosphere reduces the surface oxidation to a minimum which results in a brighter surface and a much thinner oxide layer. Picking is not needed after bright annealing since the oxidation is minimal. Since there is no pickling , the surface of stainless steel sanitary tube is much smoother which results in better resistance to pitting corrosion.

After the process, bright annealed finish has a bright, reflective appearance, but may have some cloudiness slightly different from MF (Mill Finish) 



Inside Bead Removed

Vinmay has full set of online inside bead removing equipment,bringing smooth surface for inner weld seam to meet clean purpose, and controlling the height of weld seam for precision request.  It's an important process for pipes of fluid field or food industry.

Internal Polishing

In order to produce stainless steel sanitary tubes, we have introduced a semi-automatic internal wheel polishing line. The flexible polishing wheel and fine abrasive on the surface of the steel pipe and micro-cutting are used to  achieve the polishing  process.

The roughness is an important parameter for measuring the quality of internal polishing, while our capacity is 0.2-0.7 Ra
