Butt-Welded Pipe Fitting Elbow Suppliers, Dealer, Manufacturer And Exporter In India

A Butt Weld Pipe Fitting Is Designed To Be Welded On Site At Its End(S) To Connect Pipe(S) Together And Allow Change In Direction Or Pipe Diameter, Or Branching Or Ending. This Fitting Then Becomes Part Of A System For Transporting Fluids (Oil, Gas, Steam, Chemicals. In A Safe And Efficient Manner, Over Short Or Long Distances. Other Types Of Fittings Can Be Threaded Or Socket Welded.

Long And Short Radius

Elbows Are Split Into Two Groups Which Define The Distance Over Which They Change Direction; The Center Line Of One End To The Opposite Face. This Is Known As The “Center To Face” Distance And Is Equivalent To The Radius Through Which The Elbow Is Bent.
The Center To Face Distance For A “Long” Radius Elbow, Abbreviated Lr Always Is “1½ X Nominal Pipe Size (Nps) (1½D)”, While The Center To Face Distance For A “Short” Radius Elbow, Abbreviated Sr Even Is To Nominal Pipe Size.

You Will Often Hear Sr45 Elbow Or Lr45 Elbow. The 45 Or 90 Refers To The Angle Of The Bend For Buttweld Fitting To Change The Direction Of Flow. A Long Radius Elbow (Lr 90 Elbow Or Lr 45 Elbow) Will Have A Pipe Bend That Will Be 1.5 Times The Size Of The Pipe. So, A 6 Inch Lr 90 Has Bending Radius That Is 1.5 X Nominal Pipe Size. A Short Radius Elbow (Sr45 Or Sr90) Has Pipe Bend That Is Equal To The Size Of Fitting So A 6” Sr 45 Has Bending Radius That Is 6” Nominal Pipe Size.
