Forged Lap Joint Stub End Fittings
The Forged Lap Joint Stub End Fittings are manufactured using advanced hot forging techniques, which refine the grain structure of the steel and eliminate internal voids. The result is a dense, high-strength pipe fitting that delivers superior performance in petrochemical, refinery, and high-pressure process piping systems.
Available in carbon steel ASTM A105 as well as stainless steel grades SS304 and SS316, these forged lap joint stub ends combine the economic advantages of carbon steel with the corrosion resistance of stainless steel where required. Each fitting is machined to precise dimensions after forging, ensuring perfect matching with lap joint flanges and smooth butt weld preparation. As a professional supplier of forged steel pipe fittings, we guarantee 3000 PSI pressure integrity on every piece.

Our forging workshop is equipped with induction heating furnaces, 1000 ton forging presses and CNC machining centers, enabling complete in-house production from billet to finished product. Every batch of forged lap joint stub end fittings is tested for chemical composition, tensile strength, hardness and dimensional accuracy.
We maintain strict process control records and can provide heat treatment charts, material certificates and third party inspection reports. Our quality team has more than a decade of experience serving international engineering contractors, and we are committed to delivering forged pipe fittings that meet the highest expectations.
Forged lap joint stub end fittings have a denser grain structure and higher mechanical strength than cast fittings. The forging process eliminates internal porosity and shrinkage defects, making forged fittings the preferred choice for 3000 PSI high pressure service.
Yes. We offer forged stub ends in SS304 and SS316 stainless steel in addition to carbon steel ASTM A105. Stainless steel forged fittings are ideal for corrosive media where carbon steel is not suitable.
Our standard forged range covers 1/2 inch to 24 inch. Larger diameters can be produced by forging plus machining, please contact our engineers with your specific requirements.
Yes, every order can be supplied with EN 10204 3.1 mill test certificates showing chemical composition and mechanical properties. Third party inspection by SGS or BV is also available upon request.
