Material Specification of ASTM A671 Pipe and ASTM A672 Pipe

The ASTM A671 standard outline the performance of pressure vessels manufactured from welded pressure vessel steel plates. Usage of ASTM A671 pipe in petrochemical projects mainly involves the transportation of steam, petroleum products, chemical media, and high-pressure process fluids. They are medium and high-pressure industrial piping system suitable. Some of the salient features of these pipes include stable weld quality, the manufacturing of large diameter and thick-walled pipes and customizable heat treatment and non-destructive testing based on engineering requirements. In order to ensure pipes' safety and reliability in petrochemical industries, the ASTM A671 standard specifies stringent criteria for inspection. Before delivery every batch of ASTM A671 EFW welded pipes has to go through a number of tests.

ASTM A672 Pipe is carbon based stainless steel. It is used in high-pressure applications used at moderate temperatures. These pipes are being sought after by various companies for petroleum and petroleum products, petrochemical industries, paper manufacturing, dye industries and many others. It is a common material used in the production of pipes and tubes that are used in water supply, drainage, chemical industries, and many other applications. Some of the manufacturing methods used for making these pipes are hot rolling, cold drawing, and heat expanding. They are extremely accurate in dimensions and have great strength. Along with the excellent mechanical property performance, the resistance against corrosion is also an added feature of pipes made from this material. Besides the natural corrosion resistance of the Pipes, the resistance can be improved even further by surface treatments are possible. They can be painted with black or colored oil paint, varnished, or with anti-corrosion oils. These Pipes can even be subjected to hot-dip galvanization.
