Forged Fittings
What is a Forged Fitting
- Forged Fittings are use for associating or connecting pipes, pumps, valves, & other equipments to create a piping systems below size of 2 or 4 inches in diameter.
- There are mainly two types of forged fittings called socket-weld fittings which are connected to pipes by fillet welds and second one is threaded fittings in which the pipe is screwed onto the fittings.
- The ASME B16.11, MSS SP 75, MSS SP 83, MSS SP 95 specifications cover forged fittings for both socket weld and threaded to fit ASME B36.10 and ASME B36.19 carbon, alloy, stainless steel and nickel alloy pipes of small bore size.
- It is manufactured from solid blocks of steel, that are machined to obtain the final required shape within the tolerances set by the applicable specifications
- The class of the fitting represents the maximum allowed pressure that the device can withstand.
- Class 3000 fittings are used for pipes in schedule 80/XS; Class 6000 for pipes Sch. 160; Class 9000 fittings for pipes with larger wall thickness (XXS).
- Forged Fittings joints are made by bolting together two Forged Fittings with a gasket between them to give a seal.

Quality Control
Our forged fittings will be inspected before shipment, including NDT ( PT, MT or UT test), dimension examination, PMI test. The chemical analysis and mechanical properties test is per heat number, corrosion test and other inspections are upon client’s requirement.
How to Order
When you want to get a quote or release a PO to us, pls clear the information:
Fittings type + End type ( NPT/BSP or SW) + Class + Size + Material + Standard + Order Quantity
For example, you want to buy 100 pcs 90 Elebow 3000# SW 1” for your system in stainless steel 316, the piping design is to ASME, so the description would be:
90 Elbow, 1” 3000#, A182 F316, ASME B16.11, 100PCS
Please don’t hesitate to contact us if you have any question.
