Buttweld Fittings
Industrial Pipe Fittings for Changing Direction, Branching & Diameter Transitions — Manufactured as per ASME B16.9 & MSS SP-43
Product Overview
Buttweld Pipe Fittings
Buttweld Pipe Fittings is defined as a part used in a Piping System, for Changing Direction, Branching or for change of Pipe Diameter, and which is Mechanically joined to the system. There are many different types of Fittings and they are the same in all Sizes and Schedules as the Pipe.

Types
Fitting Range
Elbow 45°/90° LR
Long Radius Elbow for smooth flow direction change at 45° and 90°.
Elbow 90° SR
Short Radius Elbow for compact piping layouts requiring 90° turns.
Elbow 180° LR/SR
Return Elbow for complete flow reversal in Long and Short Radius.
End Caps
Used to close the end of a pipe in pressure piping systems.
Reducer Concentric
Concentric Reducer for inline pipe diameter reduction with aligned centerline.
Reducer Eccentric
Eccentric Reducer for offset centerline diameter reduction, prevents air pockets.
Tee — Equal & Reducing
Equal and Reducing Tees for branching flow in piping networks.
Stub End (MSS SP-43/B16.9)
Used with Lap Joint Flanges for easy alignment and rotation in piping.
Swage Nipple — Conc. & Ecc.
Concentric and Eccentric Swage Nipples for pipe size reduction with threaded or plain ends.
