Biggest ASME SA270 Polished Dairy Tube Supplier in India
The Stainless Steel Sanitary Tube is a sanitary grade of stainless steel tubing that comes in both welded and seamless forms. ASTM A270 Sanitary Tubing solutions are used in the dairy and food industries, as well as bio processing equipment, and have a particular surface treatment. All of these tubes have been hot-treated. The ASTM A270 standard is used for manufacturing BPE Stainless Steel Tubing solutions.
These tubes are typically constructed from cold-rolled stainless steel strips. Their chemical ingredients are carefully managed to improve weldability. ASME BPE Pipe is also bright annealed in a controlled environment to provide optimal structural integrity.

The ASTM A270 Tubing solution is finished in 180, 240, or 320 grit. 180 is a fine grit that aids in the removal of scratches left by coarser grits. The 240 grit also aids in the removal of surface imperfections on metals such as stainless steel. The 320 grit is a very fine grit that is used for gentle sanding.
ASTM A270 tubes are made of acid-resistant austenitic stainless steel. It has been cold worked to achieve a minimum tensile strength of 700 MPa. Sanitary Stainless Steel Tubing Supplier primarily serves the dairy industry with 3A tubing. 3A tubes are sanitary and can be used in food processing equipment.
Sanitary Stainless Steel Tubing Supplier mechanically polishes the surface with various abrasives. Electropolishing on 316 Stainless Steel Sanitary Tubing, on the other hand, employs chemicals and electricity to dissolve the surface. Inclusions cannot be removed by mechanical polish, however electropolish makes the surface featureless.
