Buttweld fittings are pipe fittings used to change the pathway of a
pipeline (elbows), reduce/increase the pipe bore size (reducers),
branch (tees, cross) or blind a pipeline (butt weld cap); Buttweld
fittings are available in multiple shapes (elbows, tees, reducers,
crosses, caps, stub ends), material grades (carbon, high-yield
carbon, low-alloy, stainless, duplex, and nickel alloys),
and dimensions (2 to 24 inches in seamless or welded, 26"-72" in
welded ).

FAQ
Q:Customer asked for butt weld fittings in A105:
A: Most common carbon steel buttweld fitting material is A234WPB.
It is equivalent to A105 flanges, however there is no such thing as
an A105 or A106 butt weld fitting.
A106 Gr.B is for pipe grade. The A234WPB fittings are made from
A106GR.B pipes. A105 is a material from Bar forged to be High
pressure Fittings or Flange
Q: Customer requests “Normalized” butt weld fittings:
A: This is also a misconception since flanges are available in A105
and A105 N, where N stands for normalized.
However, there is no such thing as A234WPBN. Manufactures normalize
their butt weld fittings was considered that normalized heat
treating process was done, Espeically for the elbows and Tees
Customer needing “normalized” butt weld fittings should request
WPL6 fittings which are high yield and are normalized as a standard
procedure.
Q: Customer forgets to mention pipe schedule:
A: Buttweld fittings are sold as per pipe size but pipe schedule
must be specified to match the ID of the fitting to the ID of the
pipe. If no schedule is mentioned, we will assume a standard wall
is requested.
Q; Customer forgets to mention welded or seamless butt weld
fitting:
Butt weld fittings are available in both welded and seamless
configuration. A seamless butt weld carbon steel or stainless steel
fitting is made of seamless pipe and is generally more expensive.
Seamless pipe fittings are NOT common in sizes bigger than 12”.
Welded pipe fittings are made of ERW welded carbon steel or
stainless steel pipe. They are available in sizes ½” to 72” and are
more affordable than seamless fittings.
Q: What does Short Radius (SR) or Long Radius (LR) means?
A: 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 a pipe bend that is equal
to the size of the fitting, so a 6” SR 45 has a bending radius that
is 6” nominal pipe size.
Q: What is a 3R or 3D elbow pipe fitting?
A: First, the terms 3R or 3D are used synonymously. A 3R butt weld
elbow has a bending radius that is 3 times the nominal pipe size. A
3R elbow is equal to 3D Elbows
Features /Characteristics
Elbows: Such pipe fittings are used to change the direction of the flow. Elbows They are majorly available in two standard types - 90 and 45 degree angles owing to their high demand in plumbing. The 90-degree elbow is primarily used to connect hoses to water pumps, valves, and deck drains, while the 45 degree elbow is mostly used in water supply facilities, electronic and chemical industrial pipeline networks, food, air-conditioning pipelines, garden production, agriculture, and solar-energy facility.
