Sanitary ASTM A270 TP316L Stainless Steel Seamless Tube
ASTM A270 TP316L Stainless Steel Seamless and Welded Sanitary Tube
We are one of the biggest manufactures of stainless steel & duplex steel & alloy steel tubes and pipes in China. With development more than 20 years, we have accumulated a great many clients all around the world and Yuhong products also won the great praise among the customers.
ASTM A270 TP316L sanitary stainless pipe usually refers to the small pipe diameters, normally from 1/2” to 2 1/2”, thickness from 0.049 inch (1.24mm) to 0.15 inch (3.81mm). The maximum outer diameter of ASTM A270 TP316L tubing is 12 inch (316L.8 mm). ASTM A270 TP316L tubing using inch pound as the standard unit of measure. ASTM A270 TP316L Tube wall thickness tolerance shall not vary more than 12.5%.
ASTM A270 TP316L sanitary stainless steel pipe shall be noted below points during manufacturing processes:
1)ASTM A270 TP316L Seamless steel pipe should not contains any kind of welding processing.
2) ASTM A270 TP316L Welded steel pipe applied in automatic welding processing, but should not use metal materials as filler.
3) ASTM A270 TP316L Heavily cold worked (HCW) tubes shall be manufactured by cold working of not less than 35% reduction of thickness of both wall and weld to a welded pipe prior to the final anneal. Filler materials shall be noted added during welding process. The weld shall be 100% radio graphically inspected in accordance with ASME boiler and pressure vessel standards specification.
4) ASTM A270 TP316L Sanitary pipe could be furnished with hot finished or cold finished at Manufacture’s option.
