Forged Fittings

Forged fittings is the forged steel pipe fittings, including threaded fittings (NPT fittings) and socket-welding pipe fittings (SW fittings), which are commonly for high pressure for piping connections. Similar to butt-welding fittings, forged fittings has various types, such as elbow, tee, coupling, plug, threaded, union, swage nipple, outlet branch fittings etc.

In the norm ASME B16.11, the forged fittings are up to NPS 4” only because they are threaded and Socket-weld ends. For large diameter, we can accept customized manufacturing as per drawings.

Kaysuns provides quality forged fittings for oil and gas, chemical, offshore, shipping building etc industries since 2007. We can offer forged fittings in material stainless steel 304/304L, 316/316L, 316Ti, 321, 321H, 347H, 317L, 310S, 904L, 254 SMO (A182 F44), duplex 2205, super duplex 2507,  nickel alloy such as monel 400, Hastelloy C276, Inconel 600, 625, 800H, 825 etc, as well ASTM A105, A182 F5 /F9 /F11 /F22 /F91, A350 LF2 / LF3 with standard ASME B16.11, BS 3799, etc. We also accept customized forging upon the design and drawing of client.

Connected End of Forged Fittings:

  1. Threaded and socket-weld is the common types for the forged fittings connection.
  • Threaded end has male and female types for connected – Male is for such street elbow, plug, bushing, nipple etc. Female is for elbow, tee, coupling etc.
  • We can offer both NPT and BSP threaded – NPT is default screw if there is no specific.
  • Socket-weld is one pipe end to insert the fittings for welding, SW end is for all the fittings except threaded.

Dimension of Forged Fittings

We supply stainless steel forged fittings various standards, including but not limited to the followings:

ANSI B16.11, BS3799, JIS B2302, MSS SP-83, ANSI B16.11, JIS B2316, MSS SP-83, MSS SP-79, MSS SP-97,GB14626, GB/T14383 etc.

Our Capacity

Our capacity is about 100 tons/month for types of threaded fittings and socket-weld fittings. We produce and supply the forged fittings class 3000 /6000 /9000, stainless steel and duplex steel flange are our strength. For small quantity of SS and DSS, we have ex-stock for immediate shipment.

Rate:  3000LBS, 6000LBS, 9000LBS ( SCH40S, 80S, XXS etc. for pipe nipple )

Dimension:  1/2” to 4” (DN15 ~DN100)

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.

Packing

The fittings are packed in carton firstly, then in plywood box for sea or air shipment. If you have any specific, please tell us when you order.

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.
