ASTM B729 UNS N08020 or Carpenter 20 Nickel content is different from conventional stainless steel levels. Alloy 20 Seamless Pipe contains copper and has high tolerance for sulfuric acid. In addition to sulfate, when chloride or acid (nitric acid and phosphate). In addition, each sample or component belonging to the ASTM B729 UNS N08020 pipe has been tested by static water testing or non -destructive electricity testing. AlLoy 20 can be used for heat exchangers, chemical and petroleum processing equipment.

Alloy 20 Pipe Suppliers
HT PIPE is a supplier and manufacturer of the Alloy 20 tube. Contact us to get more information and quotations for free!
We can provide seamless and welded pipes. Alloy 20 seamless pipes have an outside diameter range of 0.375 inches to 1 inch, and welded pipes range from 0.125 inches to 1 inch. Seamless pipes have higher pressure bearing capacity and strength than welded pipes. Wall thickness and weight also have something to do with seamless and welded pipes.
