Buttweld Fittings

Stainless Steel Buttweld Fittings what we can provide Stainless Steel PipeElbow, Tee, Cap, Reducer and Stub End and size we can producing from 1/2 to Diameter 80.


Buttweld Elbow

Butt Weld Elbows are designed to change the direction of pipeline in a certain degree, Such as 90, 45°, 180° or some Special Degree such as 60°. Their Radius are available in Short Radius (SR), Long Radius (LR), 3D, 5D, 10D…… Generally speaking, only 90° Elbow and 180° Elbow has Short Radius Pattern. Some clients also call the Elbows with Larger Radius than LR as Bend. Pipe Bend only has Butt Weld Type.


Key Elements for ordering Stainless Steel Buttweld Fittings Elbow: Type, Diameter, Wall Thickness,Degree, Radius and Materials. Eg: 90 Degree BW Elbow 24SCH 20 LR ASTM A403 WP316.

BW Tee

Steel Pipe Tees are used as a branch connection fittings and offers a 90 Degree branch to the main pipe. The branch has same size with Run Pipes (Equal Tee) or has smaller dimensions than the Main pipe (Reducing Tee).


The key Elements Description of Buttweld Tees are Type, Diameter, Wall Thickness and Material. Eg: BW Reducing Tee 10" X 8"  SCH10, BW, ASTM A403 WP 310S. ANSI B16.9.

Stainless Steel Pipe Reducer

Steel Pipe Reducer are only available in Butt Weld End type. It is used to connect different sizeds Pipes and Adjust the flow. It can be divided into Concentric Reducer and Eccentric Reducer.


How to order a Stainless Steel Pipe Reducer? The Elements are the same as Buttweld Pipe Tees. Eg: Concentric Reducer 4x3 Sch 120, BW END, A403 WP304

Buttweld Pipe Cap

Stainless Steel Buttweld Fittings Pipe Cap is Welded to the Pipe End to close the Pipeline. As a Butt Weld Fitting which has Seamless and Welded Type. Seamless Pipe Cap is more Common and Welded Pipe Cap usually has Large Diameters.


The Description of Butt Weld Pipe Cap Example like that : Seamless Cap 8Sch 40,Butt Weld End, ASTM A403 WP310, ANSI B16.9

Stub End

Stub End Also known As Lap Joint Stub End, it is used with Lap Joint Flanges to replace Welded Fanges. We supply Type A Stub End; Type B Stub End and Type C Stub End for customers. We also offer Short Pattern and Long Pattern Stub End. The Dimension Range of stub End From 1/2 to 24.

Size, Schedule, Type, Length and Material are necessary Element for Butt Weld Stub End

Advantages For Stainless Steel Buttweld Fittings

Stainless Steel Buttweld Fittings Manufacturing Process

The general process include:

CuttingHeatFormingHeat TreatmentBeveled

For Seamless Buttweld Pipe Fittings, they are made by Cold Drawn or Hot Forming, and Welded Buttweld Fittings usually Adopt Seam Welding to get their shape.

Questions for Stainless Steel Buttweld Fittings

The Dimensions for Buttweld Fittings:

NPS 1/2to NPS 80( or DN15 to DN2000 )

The Schedule For Pipe Fittings:

Schedule, usually Shortened as Sch, is an American Standard that Refers to Wall Thickness of a Pipe or Buttweld Pipe Fitting. ASME standard defines the Wall Thickness as Sch 10s, Sch 20, STD, Sch 40, XS, Sch 80, Sch 100, Sch120, Sch140, Sch160 and Sch XXS. The Schedule is Higher and The Wall is Thicker.
