Alloy 20 is a nickel-iron-chromium based, austenitic alloy with excellent corrosion resistance in chemical environments containing sulfuric acid and many other aggressive media. This alloy is stabilized with niobium to resist intergranular corrosion. Alloy 20 may provide potential cost savings when carefully compared to higher nickel-based alloys, while out performing standard stainless steels.
Reducing pipe is also called size head, used to connect different sizes of pipe; Generally, it is divided into two kinds of concentric reducing tube and eccentric reducing tube. When the projection of the two ports after the reducing tube stands up is concentric circles, it is called concentric reducing tube, and the projection of the eccentric reducing tube is a small circle tangent to the outer circle.Reducing pipe standard: national standard, American standard, British standard and various non-standard high pressure stamping.
