Product Description

ASTM A790 UNS S31803/2205 Duplex Steel Thick Wall Seamless Pipes

Wenzhou Shangle Steel Co., Ltd. (Shangle) founded in 2017,is a comprehensive company integrating industry and trade.As a leading supplier of stainless steel products in Wenzhou, it has a wide range of products in stock that have been rigorously tested and are ready to be shipped.

 

About Grade UNS S31803

Stainless steel alloy grades such as UNS S31803 prove to be particularly useful in applications that are susceptible to stress related corrosion cracking. SCC or stress related corrosion cracking in pipes can have harmful effects on not only the workers in the factory but also to the business itself. Since ASTM A790 UNS S31803 Duplex Steel Seamless Pipe is resistant to SCC, the piping system becomes durable and it has longevity in comparison to conventional steels.

Besides having superior resistance to SCC, the ASME SA 790 UNS S31803 Pipe has improved mechanical characteristics like higher yield strength, which incidentally is almost twice that of a traditional austenitic stainless steel alloy. Pipes under specification ASTM A790, are produced either in a seamless manner or they have a welded construction. The automatic welding process used to weld the ASTM A790 Pipe is to be done without the use of any filler metal. The specification also calls for determining the percentage of elements used to alloy both ASTM A790 Grade UNS S31803 Welded Pipe and seamlessly constructed ones as well. Testing is also an important parameter of these pipes. In addition to a nondestructive electric test, the ASTM A790 UNS S31803 Seamless Pipe is required to conform to the values of tension test, flattening tests, hydrostatic tests as well as a hardening test. Perfect impex is a large manufacturer and supplier of these pipes and we produce all kinds and variations of the product. The advantage to choose ASTM A790 Grade UNS S31803 Pipe manufacturer is to get 5 to 10% discount price compare to stockist and supplier in Mumbai and Prime quality material with Mill test Certificate.
