Fittings are used in a piping system to change a direction or function, which is mechanically joined to the system. Likely 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.

The buttweld and forged steel fittings tie in perfectly with the pipe assortment and include a wide variety of different types and schedule sizes in line with our pipe and flange programme. AFF supplies seamless and welded butt weld fittings from stock with dimensions ranging from ½” to 24?. Our scope of supply includes sizes up to 100? according to customer specifications. Forged steel fittings are available in threaded and socket weld versions; dimensions ¼” to 4? and pressure classes 3.000 lbs, 6.000 lbs and 9.000 lbs. The fittings are produced by leading manufacturers in accordance with the highest quality requirements.

Elbows, Tees, Reducers and Caps are some of the fittings in our range.


Elbow fittings 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.



Tee fittings are 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 tee fittings are engineered to close tolerances and precise dimensions.



There are two types of reducer fittings – Concentric and Eccentric.

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.
Concentric Reducers have 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.

Eccentric reducers are also called bell reducers, they have 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.
This 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.



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