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.

Socket Weld Elbow Fittings

The Socket Weld Elbow Fitting is a pipe fitting installed between two lengths of pipe or tube allowing a change of direction, usually 90° or 45°. The ends can be be machined for screwed (usually female), or socketed. 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.

Socket Weld Tee Fittings

Socket Weld Tee Fitting is used to either combine or split a fluid flow. The most common Socket Weld Tees have the same inlet and outlet sizes, but ‘Reducing’ Socket Weld Tees are available as well.

Socket Weld Cross Fittings

Socket Weld Cross Fitting has one inlet and three outlets, or vice versa.

Socket Weld Couplings

Socket Weld Pipe Coupling fitting connects two pipes to each other. If the material and size of the pipe are not the same, the fitting may be called a ‘Reducing Coupling’ or Reducer, or sometimes an Adapter.

Socket Weld Cap Fittings

Socket Weld Cap is a type of pipe fitting, usually liquid or gas tight, which covers the end of a pipe to stop flow. A Cap has a similar function to a Plug.

Socket Weld Union Fittings

Socket Weld Union Pipe Fitting is similar to a Coupling, except it is designed to allow quick and convenient disconnection of pipes for maintenance or fixture replacement. While a Coupling would require either solvent welding or being able to rotate all the pipes adjacent as with a Threaded Coupling, a Union provides a simple nut transition, allowing easy release at any time.

Pipe Nipples and Barrel Nipples

Pipe Nipple or Barrel Nipple is defined as being a short stub of pipe which has two male ends. Nipples are commonly used for plumbing and hoses, and second as Valves for funnels and pipes.

Concentric Swages and Eccentric Swages

The most common use of Swaging is to attach fittings to pipes or cables (also called wire ropes); the parts loosely fit together, and a mechanical or hydraulic tool compresses and deforms the fitting, creating a permanent joint. Pipe flaring machines are another example. Flared pieces of pipe are sometimes known as “Swage Nipples,” “Pipe Swages,” or “Reducing Nipples.

Socket Weld Reducing Inserts

This is a Socket Weld version of a Bush. Reducer Insertscomply with MSS Standard SP-79. They enable standard Socket Weld Fittings to be used for making any combination of pipe line reductions, quickly and economically. Socket Weld Reducer Inserts serve the same purpose as Threaded Reducing Bushings with threaded fittings.

Buttweld Branch Outlet Fittings

“Outlet” is a generic term for all branch type connections. They can come with Threaded, Socket Weld, and Butt Weld end connections. The most common types are used in place of a Tee. A hole is cut in the side of the pipe, the Outlet is welded in place over the hole and then the additional length of pipe is attached to the Outlet.

Similar to reducing Tees, Outlets are usually described by two sizes. The Run or Header size refers to the pipe on which the Outlet is mounted. The Outlet or Branch size refers to the length of pipe branching off of the run.

This type of fitting is contoured to match the curve on the Header Pipe and beveled on the Branch side to mate up with a beveled piece of the branch pipe.

Screwed Plugs

Screwed Plug pipe fitting closes off the end of a pipe. It is similar to a Screwed Cap but it fits inside the fitting it is mated to.

Screwed Bushes & Hex Bushes

Screwed Bushes and Hex Bushes are pipe fittings of which the external thread is larger than its internal thread to allow two pipes of different sizes to be connected together. A pipe fitting with male and female threads that extends a run by joining two pipes of different diameter.

Also, a removable lining or sleeve inserted or screwed into an opening to limit its size, resist wear or corrosion, or serve as a guide.

Pipe Nipples and Barrel Nipples

Pipe Nipple or Barrel Nipple is defined as being a short stub of pipe which has two male ends. Nipples are commonly used for plumbing and hoses, and second as Valves for funnels and pipes.

Male / Female 90° Street Elbows

Street Elbow is a type of plumbing or piping fitting intended to join a piece of pipe and another fitting at an angle. The difference between a “Street Elbow” and a regular Elbow is the nature of the fittings on either end.

A Street Elbow has a female fitting (hub or FIP) on one side and a male pipe or MIP fitting on the other end. The advantage of the Street Elbow is that it can be connected directly to another fitting without having to use a short connecting piece called a pipe Nipple.

They can be used in water supply, drainage, sewer vents, central vacuum systems, compressed air and gas lines, HVAC, sump pump drains, and any location where plumbing fittings would be used to join sections of pipe.
