Product Description

CARBON STEEL BUTTWELD PIPE FITTINGS


Bangdong Supply Carbon Steel Seamless Pipe Fittings ,Carbon Steel Welded Pipe Fittings ,Carbon Steel Spiral Welded Pipe Fittings .We are specialized in offering carbon steel fittings which are used in various engineering applications and can be availed in various grades like Astm A234 , ASTM A860, ASTM A350, astm a420 wpl6 ,ASTM A106 Grade B these grades are available in the form of carbon steel fittings. Multimetals India offers a complete range of pipe fittings such as carbon steel reducer, carbon steel elbow, carbon steel tee, carbon steel cross, carbon steel stub ends and Carbon Steel Pipe bends.



Buttweld pipe fittings comprises of long radius elbow, Concentric Reducer, eccentric reducers and Tees.They are an important part of industrial piping system to change direction, branch off or to mechanically join equipment to the system. Buttweld fittings are sold in nominal pipe sizes with specified pipe schedule. BW fitting`s dimensions and tolerances are defined as per ASME standard B16.9.

Butt Weld fittings are also called Welded Pipe fittings. These welded fittings in carbon steel and stainless steel offer many advantages compared to threaded and socketweld fittings. The later are only available up to 4-inch nominal size whereas butt weld fittings are available in sizes from ½" to 102".



LR 90 Elbow: Fittings that change direction in a piping system are called elbows. The directional change is given in degree such as 45 or 90. Long radius 90 degree elbow has the center line of elbow at 1.5 x NPS from eblow end. 3R elbow has center line at 3 x NPS from elbow end.

LR 45 Elbow: Long radius 45 degree elbow changes the direction by 45 degrees.

LR 45D Elbow


SR90 Elbow: Short Radius 90 degree elbow is same as LR90 except for the measurement between end of elbow to center line is 1 x NPS.
LR 180 degree Bend: Long Radius 180 degree return bend allows complete reversal of flow. The distance between end of elbow and center line is 3 x NPS.
SR 180 degree Bend: Short Radius 180 degree return bend allows complete reversal of flow but in a much tighter turn. The distance between end of elbow and center line is 1 x NPS.

Alloy pipe fitting (633)


Tee: Butt weld pipe Tee allows a 90 degree branch off from a running pipe.This allows for connecting auxiliary equipment to a pipe. A tee is welded on both side to the pipe, leaving the branch open for branch off.

Alloy pipe fitting (373)


Reducing Tee : Butt weld reducing tee has a branch that is smaller than main run. This allows for branching off to a smaller pipe of equipment from the main run.
Concentric Reducer: A concentric Reducer is also called welded concentric coupling. It allows from connecting a large pipe to a smaller pipe by means of welding. A concentric reducer allows welded connection between two pipes with the same center line.

Alloy pipe fitting (698)


Eccentric Reducer: An eccentric reducer is also called welded eccentric coupling. It allows for welding a large pipe to a smaller pipe with an offset center line. The offset of the center line in an eccentric reducer is; Offset = 1/2 x (Largest ID - Smallest ID)

Welded Stub End: Stub ends are used with Lap Joint Flange to welded onto the pipe.

Butt Weld Pipe Fitting Bevel

All welded pipe fittings have bevelled end to allow for ease of welding. This bevel allows for full penetration weld in most cases. There are two types of bevels;

Plain Bevel and Compound Bevel.


Buttweld Pipe Fitting Specification & Standards

Welded pipe fittings are made as per ASME spec B16.9. Asme B16.9 covers factory made wrought steel butwelding fittings in sizes 1/2" to 102". This standard however does not cover low pressure corrosion resistant buttwelding fittings. See MSS SP-43, Wrought Stainless Steel Butt-Welding Fittings.

Common Materials for Welded Pipe Fittings

Carbon Steel Welded Fitting:

A234 WPB is the most common material used for carbon steel butt welded fittings.

ASTM A234 WPB is the Standard Specification for Piping Fittings of Wrought Carbon Steel and Alloy Steel for Moderate and High Temperature Service.

How a Butt Weld Fitting is Made?

A butt weld pipe fitting is made by the process of hot forming that includes bending and forming to shape. The starting material of butt weld fitting is a pipe that is cut to length, heated and molded into specific shapes by means of dies. Heat treatment is also done to remove residual stresses and obtain desired mechanical properties. Read the link here to get more in depth detail of butt weld fitting manufacturing.

Benefits of Butt Weld Pipe Fittings

Welded connection offers more robust connection

Continuous metal structure adds to the strength of the piping system

Buttweld fittings with matching pipe schedules, offers seamless flow inside the pipe. A full penetration weld and properly fitted LR 90 Elbow, Reducer, Concentric reducer etc. offers gradual transition via welded pipe fitting.

Option of various turn radius using Short Radius (SR), Long Radius (LR) or 3R Elbows

Cost effective compared to their expensive threaded or socket weld counter parts.

Stainless Steel Welded Fittings are also available in SCH 10, allowing a more thinner wall option.

Stainless Steel Butt Weld Fittings are more common in SCH 10 and SCH 40 configuration.

All butt weld fittings have beveled ends as per ASME B16.25 standard. This helps create full penetration weld without any extra preparation needed for the butt weld fitting.

Butt weld pipe fittings are most commonly available in carbon steel, stainless steel, nickel alloy, aluminum and high yield material. High yield butt weld carbon Steel Pipe fittings are available in A234-WPB, A234-WPC, A420-WPL6, Y-52, Y-60, Y-65, Y-70. All WPL6 pipe fittings are annealed and are NACE MR0157 and NACE MR0103 compatible.


Butt weld fittings is one of the most popular connection type in pipeline systems. It always been required in large quantities in different industries, and especially for the large diameter pipelines.
