ASTM A312 Standard For Stainless Steel Pipes

ASTM A312 Standard For Stainless Steel Pipes

Stainless steel is a high-alloyed steel. Its mechanism forms a dense oxide film made of alloying element to prevent oxidation. In the chloride environment, stainless steel also corrodes quickly. The corrosion rate is even faster than carbon steel. Chloride ion exists everywhere in our daily life such as salt, sweat, seawater, sea wind and soil. Therefore, stainless steel does not mean that it does not get rusty forever. If you want to protect it well, you need to keep it clean and dry. 

ASTM A312 standard for stainless steel tube mainly contains seamless pipe and straight-seam weld pipe, details as follows,

Major grade: TP304, TP304L, TP304H

                   TP316, TP316L, TP316H

Pipe end:   plain ends,bevel ends,threaded

Packing and Delivery

We wrap the pipe bodies around with woven strip and put them into wooden cases,then carry by container ships.

Inspection

Usually,we will inspect the size of out diameter and wall thickness before shipment.

Application 

Maybe you wondered which conditions we used the stainless steel pipes. They are used in a wide range of applications and various industries. Furthermore, TP304 and TP 316 series have reached the food standard. In addition,TP316 series is applicable in surgical operations and medical tools.
