ASTM A182 ASME B16.11 Forged Fittings, Socket-Welding and Threaded

Name: ASTM A182 ASME B16.11 Forged Fittings, Socket-Welding and Threaded
Brand: Wenzhou Kidy Pipeline Materials Co., Ltd.

The socket fitting is mainly a high-pressure elbow pipe accessory formed by forging round steel or steel ingots into blanks and then processed by a lathe. Its connection form is socket welding (Socket Welding SW), where the steel pipe is inserted into the socket hole for welding. The common product categories of socket fittings include: socket cap, socket 45 ° elbow, socket 90 ° elbow, socket equal diameter four-way, socket equal diameter four-way, socket equal diameter three-way, socket different diameter three-way, socket pipe clamp, socket movable joint, etc. Screw fittings refer to threaded fittings made of materials such as stainless steel, alloy steel, carbon steel, etc., suitable for connecting various pipelines. The types of threaded pipe fittings can be subdivided into more than ten types, covering various forms such as straight connections and curved connections, including threaded elbows, threaded tees, threaded pipe clamps, threaded pipe caps, threaded unions, threaded short joints, reducing short joints, hexagonal external threads, threaded pipe plugs, and threaded cores. The use of socket fittings is mainly suitable for high-pressure pipelines that require high pressure, equipment with precise size requirements, and various other high-pressure fields such as petrochemicals, medicine and health, power, aerospace, fire protection, metallurgy, shipbuilding, gas, nuclear power, and environmental protection.
