Coupling is a kind of pipe fittings.Used to connect two pipes or change the flow rate of the pipeline.Pipe couplings are highly demanded in the market.

Forged coupling is a high pressure pipe coupling.It is made from round steel bar,and then machining the socket bores by CNC machine.Socket weld coupling can bear higher pressures than threaded couplings.

Forged couplings have two different connection methods to the pipes:threading and socket welding.Therefore there are three types of forge coupling: socket weld couplings,threaded couplings and socket weld to threaded couplings.

Accoding to the ends,Forged socket weld couplings have two types: full coupling socket weld and half coupling socket weld.Socket weld full coupling has both ends with socket welded;SW half coupling is only one end socket welded,the other end can be welded directly to a pipe.

According to the shapes,socket weld couplings can be divided into Straight coupling and reducing coupling socket weld.

We has big advantages on forged fittings.Especially carbon steel fittings and stainless steel fittings.During the past 20years,EATHU continuously improve the technology, update the equipments, and accumulated rich experience.Now we can provide high quality forged steel fittings with competitive prices .Also we always keep LARGE AMOUNT of raw materials and finished forged fittings products IN STOCK which allow us to short the delivery time and make the prices stable.

Socket Weld Half Coupling Dimension

(1) Dimensions in Millimeters.

(2) Average of socket wall thickness around periphery shall be no less than listed values. The minimum values are permitted in localized areas.

(3) Upper and lower values for each size are the respective maximum and minimum dimensions.
