ASME B16.11 ASTM A105 Threaded And Scoket Coupling

Coupling: A coupling is a short pipe used to connect two pipes. Also known as external connector or internal wire. Pipe clamps are widely used in civil construction, industry, agriculture and other fields due to their convenient use. According to the connection form, there are socket welded pipe clamps and threaded pipe clamps, which are further divided into single socket pipe clamps and double socket pipe clamps; Threaded pipe clamps are divided into single interface pipe clamps and double interface pipe clamps According to material classification, there are: carbon steel, stainless steel, alloy steel pvc, Plastic, etc. The connection methods include threaded connection, welding, and fusion welding. According to its manufacturing process, it can be divided into two types: forging and casting. Forging refers to the process of forming steel ingots or round bars by heating and forging, and then threading them onto a lathe. Casting refers to the process of melting steel ingots and pouring them into a fixed pipe clamp mold, and then cooling them down to form the product.

Pipe couplings made of round steel or steel ingots are machined after forging. Their connection form is socket welding (SW), where steel pipes are inserted into socket holes for welding. Therefore, they are called "pipe couplings" and their main manufacturing standards are ANSI/ASME B16.11 and GB/T 14383-2008. The varieties of socket clamps include double socket clamps and single socket clamps. There are two types of double socket pipe clamps: equal diameter and reduced diameter, and reduced diameter double socket pipe clamps can also be concentric or eccentric. Tube clamps can be widely used for pipes of different diameters, including single, three-way, four-way, etc., and can also be used for water meters and valves. Due to the use of socket structure, the cost of pipeline joints is reduced, and installation, use, and maintenance are extremely convenient. At the same time, it also has leak prevention capability, which has great market prospects.
