ASTM A270 / ASME SA270 TP316LSanitary Stainless Steel Welded Pipe
ASTM A270 sanitary pipe is specifically designed for use in the food, dairy, beverage, and pharmaceutical industries where cleanliness and sanitation are of utmost importance. The pipe is also subjected to various tests such as hydrostatic testing, eddy current testing, and pneumatic testing to ensure that it meets the required standards. Additionally, the pipe is polished to a specified finish to eliminate any surface imperfections that could harbor bacteria or other contaminants.
ASTM A270 Sanitary Stainless Steel Pipe Specification
ASTM A270 sanitary stainless pipe usually refers to the small pipe
diameters, normally from 1/2” to 2 1/2”, thickness from 0.049 in

What the Difference Between Sanitary Seamless and Welded Pipe?
Sanitary seamless pipes are produced by piercing a solid billet of stainless steel and then drawing it over a mandrel to create the desired shape and size. This process results in a pipe with a smooth, continuous surface that is free from any welds or seams.
Sanitary welded pipes are made by rolling a flat strip of stainless steel into a tube shape and welding the edges together using a Tungsten Inert Gas (TIG) welding process. This process can result in a pipe with a slightly uneven surface due to the presence of the weld seam.
Both types of pipes can be used in sanitary applications as long as they meet the required standards for cleanliness, corrosion resistance, and surface finish. However, seamless pipes are generally preferred in applications where a completely smooth surface is required to prevent the buildup of bacteria and other contaminants.
