Reducers

Concentric Reducer

A concentric reducer joins two pipes of different sizes on a common axis. EN 10253-1 (Form 1 and Form 2) in S235, and ASME B16.9 in A234 WPB.

Change pipe size along the same axis

A concentric reducer keeps both pipes centred on the same axis. It is the reducer for vertical lines, pump discharges and most size changes where there is no risk of an air pocket or of deposits.

EN 10253-1 defines two forms: Form 1, shorter, and Form 2, longer with a more gradual cone. Under ASME B16.9 the length is set by the large end. Our reducers cover large end Ø 33.4 to 219.1 mm, small end Ø 26.7 to 168.3 mm, in black or galvanized S235 and painted A234 WPB.

On a horizontal pump suction line, use an eccentric reducer instead.

Manufacturing standards

Made to the following dimensional and material standards. Inspection certificate to EN 10204.

Standard

ASME B16.9

Factory-made wrought butt-welding fittings. North-American reference for dimensions and tolerances.

Standard

EN 10253-1

European standard for butt-welding pipe fittings, Part 1, carbon steel without specific inspection requirements.

Frequently asked questions

What is the difference between EN 10253-1 Form 1 and Form 2?

The length: Form 2 is longer and the change of diameter more gradual, which slightly lowers the pressure drop. Form 1 is more compact.

Concentric or eccentric: how to choose?

Concentric for vertical lines and pump discharges; eccentric on horizontal lines to avoid an air pocket (pump suction, flat side up) or to let the line drain (flat side down).

How do I specify a reducer in a quote request?

Give both outside diameters and both wall thicknesses, for example 114.3 × 3.6 – 76.1 × 2.9, with the standard and the finish. The easiest way is to add the references from the table below to your quote list.
