Buttwelding Fittings Catalogue

  • To Change Directions

Butt Weld Elbows are used to connect two pipes with same or different nominal diameters, and to make the pipe turn to a certain direction of 45 degree or 90 degree.

Types: 90 Degree Elbow, 45 Degree Elbow, 180 Degree Elbow. Stainless Steel Pipe Bend

  • To Provide Branches

Butt Weld Tees are used to join three different pipes forming a junction. It is normally called as “3-way fitting”. It symbolizes an alphabet “T” which include two inlets and single outlet.
There are two types that Equal Tee and Reducing Tee.

  • To Block Pipeline

Butt Weld Caps are used to weld and block end of pipeline. We call it as Pipe Cap and End Cap.

  • To Reduce Pipe Dimensions

Butt Weld Reducers are connected with pipes in different diameters.
Concentric Reducer, Eccentric Reducer, Reducing Elbow

  • To Use With Flanges

Lap Joint Stub Ends are used in combination with a lap joint flange to make flanged connections.

Package of Stainless Steel Buttweld Fittings

We marked all Stainless Steel Buttweld Fittings with Grade, Lot No, Size, Standard and Schedule Thickness. The workers wrapped Stainless Steel Pipe Fittings with film individually. For the small diameter pipe fittings, we will pack them into wooden cases in the end, and use pallets to pack large diameter pipe fittings.

Buttweld Fittings vs Socket Weld Fittings

  • Standard

ASME B16.9 for buttweld fittings
ASME B16.11 for socket weld fittings

  • Dimensions

BW : 1/2″ to 48″

SW: 1/8″ to 4″

  • Manufacturing

BW: Hot Forming

SW: Forging

  • Price

Normally, the price of socket weld fittings is higher than butt weld fittings in similar size. But the extra cost of butt weld is higher for installation, considering labor cost and skilled welder.
