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.
