(1) Preferred pipe materials When selecting steel pipe materials, metal materials are generally considered first. When metal materials are not suitable, non-metal materials are then considered. For metal materials, steel pipes are preferred, and non-ferrous metal materials are considered later. Amo

There are many types of heat treatments for stainless steel pipe fittings, including solution treatment, stabilization treatment, stress relief treatment, and weld heat treatment. 1. Solution treatment is to heat stainless steel pipe fittings to the austenite zone to fully dissolve chromium and o

What is normalizing steel pipes? Normalizing steel pipes is a heat treatment that improves the toughness of steel. After the steel component is heated to 30~50°C above the Ac3 temperature, it is kept warm for some time and then air-cooled. The main feature is that the cooling rate

The anti-corrosion spiral steel pipe for water supply and drainage is a layer of polyethylene (PE) resin, ethylene-acrylic acid copolymer (EAA), epoxy (EP) powder, and non-toxic polypropylene (PP) with a thickness of 0.5 to 1.0 mm melted on the inner wall of the steel pipe. Or steel-plastic composit
