The socket pipe fittings are mainly divided into high-pressure pipe connection fittings which are formed by die-casting forging of round steel or steel ingots, and then formed by lathe machining, and the pp resin modified polypropylene low-pressure pipe is connected with the curved elastic double-ducted socket. Double-melt pipe fittings.
The socket connection series includes: socket welding connection (SW), butt welding connection (BW), threaded connection (TR), curved elastic double-melt socket connection.
The socket fittings are subjected to pressure grades. Generally, the pressure grades of the socket welding and butt welding joints are classified into 3000LB (SCH80), 6000LB (SCH160), and 9000 (XXS). The pressure rating of the pipe fittings is divided into 2000LB, 3000LB and 6000LB.
The nominal pressure of the curved elastic double-pressure pipe fittings: PN2.5MPa.
Common socket fitting types:
90 degree socket welding elbow, 45 degree socket welding elbow, socket welding equal tee, socket reducer tee, socket weld union, socket weld cap, socket weld Hoop, socket welding reducer joint, socket welded pipe table, double socket pipe clamp, single socket pipe clamp, socket type pipe joint, socket welding pipe hoop, socket thread elbow, forged thread buckle Head, forged elbow, forged socket elbow, forged socket tee, forged socket tee, forged union, forged high pressure union, forged thread union, forged stainless steel Union, internal thread union, inner wire union, forged threaded union, Y-type tee, internal thread elbow, internal thread tee, internal threaded cross, female threaded hose, internal threaded pipe, Four-way, cap, plug, pipe hoop, inner wire, outer wire, concentric, eccentric head, single and double socket pipe, live joints, etc.
Pipe fittings manufacturing standards refer to: CJ/T 321-2010, ASME B16.11, HG/T 21634-1996, MSS SP-83, MSS SP-79, MSS SP-97, MSS SP-95, GB/T 14383-2008 , SH/T3410-96, GD2000, GD87, 40T025-2005, etc., can also be produced according to the drawings for non-standard processing.
Commonly used raw materials for socket pipe fittings are generally divided into carbon steel, stainless steel, alloy steel, polypropylene ppr and so on.
Commonly used carbon steel grades are Q235, 20#, A105, etc.;
Commonly used grades of stainless steel are 304, 304L, 316, 316L, 321, 00Cr17Ni14Mo2, etc.;
Commonly used alloy materials are 15CrMo, 1Cr5Mo, 16Mn, 12Cr1MoV, F11, F22, 10CrMo910, etc.
Other materials: copper alloy, nickel alloy, etc.
The socket fittings are mainly used in sectors and fields such as petrochemical, medical and health, electric power, aerospace, military, fire, metallurgy, shipbuilding, gas, nuclear power, and environmental protection, which are subject to high pressure and precision.
