Introduction

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.


EATHU 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.

Marking & Packing

Products are packaged to ensure that there is no damage during transit. In case of exports, the standard export packaging is done in wooden cases. All forged fittings are marked with Grade, Lot No, Size, Degree, and our trademark. On special requests, we can also, make custom marking on our products.

Quality Assurance

At MetalGoods, all fittings and flanges are subject to strict inspection at each stage of the production process, from starting material purchasing to product dispatch. They are visually examined for conformity to ASTM, ASME, MSS, DIN, EN, and JIS codes and standards. Upon request, official certified Inspection Agencies can be called in to witness the material reports, dimensions and quality conformity of products.

Test Certificates

Manufacturer Test Certificate as per EN 10204 / 3.1B, Raw Materials Certificate, 100% Radiography Test Report, Third Party Inspection Report.
