ASTM A270 TP316L Sanitary Stainless Steel Seamless Pipe U Bend for Dairy and Food Industries
ASTM A270 covers the grades of seamless, welded and heavily cold worked austenitic and ferritic/austenitic stainless steel sanitary pipes. Seamless pipes are manufactured using a process that does not involve welding at any stage, while welded pipes use an automated welding process with no filler metal added. Heavy cold-worked pipes are cold-worked to a reduction of not less than 35% in wall thickness and weld thickness prior to final annealing.
All materials are supplied in heat treated condition and undergo rigorous testing including chemical analysis, mechanical tests such as reverse flattening test, hydrostatic test, or non-destructive electrical test.
