asme b16.11 bs3799 union sw/thread forged fitting

Socket union is a pipe connection piece machined after die forging of round steel or steel ingot. Its connection form is socket welding and screw thread connection. Socket welding is to insert steel pipe into socket for welding. The main manufacturing standards are ASME B16.11, MSS SP 83. Socket unions are divided into two types: equal diameter and different diameter.
The socket union is composed of a socket, a socket, a socket, etc. It is characterized in that there is a socket on the socket, and the socket and socket are located at both ends; the design is reasonable, the operation is simple, the practicability is strong, and the operation quality is improved. and convenience.
The pressure rating of socket union is generally divided into 3000LB (SCH80), 6000LB (SCH160) and 9000 (XXS) for pipe fittings in the form of socket welding and butt welding. The pressure grades of pipe fittings in the form of threaded connections are divided into 2000LB, 3000LB and 6000LB.
   Socket elbow materials are generally divided into: carbon steel, stainless steel, alloy steel, etc.
Carbon steel material: Q235, 20#, A105, etc.;
Stainless steel material: 304, 304L, 316, 316L, 321, 00Cr17Ni14Mo2, etc.;
Socket unions can be widely used in pipes of different diameters, mainly for petrochemical, medical and health, electric power, aerospace, military, fire protection, metallurgy, shipbuilding, gas, nuclear power, and environmental protection, etc. departments and fields. It can also be used for water meters and Valves. Due to the socket structure, the cost of the pipe joint is reduced. The installation, use and maintenance are extremely convenient, and at the same time, it has a very high leak-proof ability, which is widely accepted by the market.
