Buttweld Fittings

We supply a wide range of Buttweld Fittings. Widely used in Oil, Gas, Filtration, Refrigeration, Refining, Petrochemical and Offshore Industries.

Buttweld Fittings are used in a piping system to change a direction or function, which is mechanically joined to the system. Probably the simplest way to achieve this would be to bend the pipe in the direction required, but this process will stretch and thin the outer wall of the pipe whilst thickening and wrinkling the inner wall of the pipe. This results in flow resistance and accelerated wall erosion.

A second method sometimes used is a mitred joint, where steel Buttweld Fittings are cut to the correct angle and welded together to achieve the desired change. Whilst the cross-section area and wall thickness are maintained a great deal of efficiency is lost due to friction and turbulence resulting from the severe change in direction; for example a single-mitred bend offers about six times the resistance of a swept elbow. 
 

 

 

Buttweld Elbow Fitting

The Buttweld Elbow Fitting is a pipe fitting installed between two lengths of pipe or tube allowing a change of direction, usually 180°, 90° or 45°. The ends are machined for Butt Welding when the two ends differ in size, it is called a Reducing or Reducer Elbow.

Most elbows are available in short radius or long radius of types. The short radius elbows have a center to end distance equal to the NPS in inches, while the long radius is 1.5 times the NPS in inches. 
 

 

 

Buttweld Tee Fitting

Buttweld Tee Fittings are widely used in industrial tubing to merge or divide fluids and do not require special tubing preparation before applications. Available in different threading specifications and various grades Buttweld Tee Fittings are engineered to close tolerances and precise dimensions.

 

 

Buttweld Cross Fitting

Buttweld Cross Fittings are used in several industries for providing leak free and torque free sealing in any piping or tubing connection. Offered in various grades Buttweld Cross Fittings are reckoned for their close tolerances and excellent finishes.

 

 

Buttweld Cap Fitting

The function of a Buttweld End Cap Fitting is to block off the end of a line in a piping system. The Buttweld Cap is fitted by placing the end cap over the open line and welding around the joint.

 

Buttweld Stub End Fitting

Stub Ends are installed in pairs and mated together with two Lap Joint Flanges. The surface of the stub end has a phonographic serrated gasket surface which prevents leakage at the joint. Using stub ends allows sections of the line to be opened for cleaning, inspection or quick replacement etc, without the need to re-weld.

 

 Eccentric / Concentric Reducer Fitting

There are two options available, of Concentric Reducer or Eccentric Reducer.

 An Eccentric Reducer, also called a Bell reducer, has two female (inside) threads of different sizes with centers so designed that when they are joined, the two pieces of pipe are not in line with each other, but they can be installed so as to provide optimum drainage of the line.

The fitting is designed with the smaller outlet off center to the larger end, allowing it to align with only one side of the inlet. The reducer fittings are designed to be welded with ease and offer superior strength and leak resistance.

Eccentric Reducer must be installed with straight side up to prevent trapping air at the pump suction. They are designed to allow simple connection of different sized pipes. These can be used as pipe reducers, flexible connectors and vibration eliminators.

Eccentric Reducers eliminate noise and isolate vibration in the pipeline, reduces stress, eliminates electrolysis and protects against start-up surges.

 A Concentric Reducer joins the tube sections on the same axis. They connect unequal size pipes that have a common centerline and are used for TC transitions in vertical tubing.

A Concentric Reducer has different size ends to mate hose or tubing of different diameter that joins tube sections on the same axis. Since virtually all piping systems go through changes in diameter either in the run or at the equipment connections, a reducer serves the dual purpose of changing the piping diameter and at the same time that of handling the expansion, misalignment or vibration problem.

While there are published transition sizes and face to face dimensions, it is seldom that the cataloged sizes refer to what is required on the jobsite. Hence, the face to face dimensions as well as the two flange sizes are varied to fit the application. Thus, Custom reducers are easily manufactured as per the specifications.
