Forged carbon steel socket pipe is the most widely used connection accessories for high-pressure pipelines. It is formed by die forging blanks of round steel or steel ingots, and then machined to form by lathe. The series connection forms of socket pipe fittings include: socket welding connection ( SW), butt welding connection (BW), threaded connection (TR), and socket fittings are classified into: 45° elbow, 90° elbow, tee, cross, union, pipe clamp, plug
The pressure rating of socket and socket fittings is generally divided into 3000LB (SCH80), 6000LB (SCH160) and 9000 (XXS) in the form of socket welding and butt welding connection. The pressure grades of pipe fittings in the form of threaded connections are divided into 2000LB, 3000LB and 6000LB.
Socket fittings are generally divided into: carbon steel, stainless steel, alloy steel,
Carbon steel material: Q235, 20#, A105, etc.;
Stainless steel material: 304, 304L, 316, 316L, 321, 00Cr17Ni14Mo2, etc.;
Socket fittings are mainly used in petrochemical, medical and health, electric power, aerospace, military, fire protection, metallurgy, shipbuilding, gas, nuclear power, and environmental protection and other departments and fields that require high pressure and precise dimensions.
