About Buttweld Fittings

• Butt welding is a commonly used technique in
  welding that can either be automated or done by
  hand on steel pieces. It is used to attach two
  pieces of metal together such as pipe, framework
  in factories, and also flanges.

Elbow

• An elbow is a pipe fitting employed between two
  lengths of pipe or tubing to connect pipes and
  change of direction, these elbows may be machined
  for butt welding (BW) or socketed welding (SW)
  etc.

Equal Tee

• Butt-weld Equal Tees are widely used in wide
  range of industries such as power generation,
  shipbuilding, oil gas, pulp and paper mills,

Unequal Tee

• Unequal Pipe Tee is a type of fitting that has a
  T shape and is used to join two or more plumbing
  pipes. Due to its corrosion resistance, sturdy
  and durable properties, these unequal tees are
  capable of withstanding high pressure
  temperature and resisting to corrosion.

Reducing Tee

• The reducing tee is used as the branch has a
  smaller diameter as the run-pipe. A reducer can
  be used either as a nozzle or as diffuser
  depending on the mach number of the flow.

Equal Cross

• Cross fittings may stress pipes as temperatures
  change, because they are at the center of four
  connection points. Similar to an equal tee, this
  equal cross has 4 ends of the cross are in equal
  diameter.

Reducing Cross

• The Reducing cross is a type of the pipe
  fittings. Reducing Cross is also called as
  unequal pipe cross, it is the pipe cross which
  the four branch ends are not in the same
  diameters.

Concentric Reducer

• A concentric reducer is used to join pipe
  sections or tube sections on the same axis.
  The concentric reducer is cone-shaped, and is
  used when there is a shift in diameter between
  pipes.

Eccentric Reducer

• An eccentric reducer is a fitting used in piping
  systems between two pipes of different diameters.
  They are used where the diameter of the pipe on
  the upstream side of the fitting is larger than
  the downstream side.

Pipe Cap

• Caps, usually liquid- or gas-tight, cover the
  otherwise open end of a pipe. A cap attaches to
  the exterior of a pipe and may have a
  solvent-weld socket end or a female-threaded
  interior.

Stub End

• The Stub End, which essentially a short length of
  pipe, which has one end that is flared outwards
  and the other end prepared to be welded to pipe
  of the same Nominal Pipe Size (NPS), material and
  of a similar wall thickness.
