Types of Carbon Steel Pipe Reducer

Carbon Steel Concentric Reducer

Concentric Reducer

The concentric reducer is made with both inlet and outlet on a common center line. Compare with eccentric type, it is less costly to manufacture adaptable to most piping installations.

Carbon Steel Eccentric Reducer

Eccentric Reducer

The eccentric reducer has the reducing outlet end off center. In contrast with concentric reducer, that can be hung or suspended flush against a flat ceiling or wall.

Butt Weld Reducer Weight Chart

The weight chart is available in concentric and eccentric reducer which based on the ASME / ANSI B16.9 . The weight for the size more than DN1200 (NPS 48) is calculated on the basis of thickness 9.53mm.

What is Buttweld Pipe Reducer?

Steel pipe reducer is used in piping system to change the diameter of pipe. ANSI / ASME B16.9 Butt weld pipe reducer is an pipe connector or pipe joint that reduces the size of pipe from larger diameter to smaller. The reduction in size is mainly equal to the average smaller and larger pipe diameter. It comes in two types that Concentric Reducer and Eccentric Reducer. The Concentric Pipe Reducer is used in vertical piping system. The Eccentric Pipe Reducer is used in horizontal piping system.

Stainless Steel Pipe Reducer Dimensions

Stainless Steel Concentric Reducer

BW Concentric Reducer

Concentric Reducers are used to join pipe or tube sections of different diameters on the same axis. They provide an in-line conical transition between pressurized pipes of differing diameters.

Stainless Steel Eccentric Reducer

BW Eccentric Reducer

Stainless steel eccentric pipe reducer fitting is manufactured with the smaller outlet off center to the larger end, which allows it to align with only one side of the inlet.

Seamless Reducer

It is manufactured from seamless steel pipe, the manufacturing methods are hot and cold forming process. Usually the diameter is below 24 inch.

Weld Reducer

Weld reducers are manufactured from Welded Pipe with filler material (ERW & EFW pipes cannot be used to manufactured fittings). Large diameter fittings are manufactured from steel plate. The process is rolling the steel plate, then welding, forming by hot or cold.

Stainless Steel Pipe Reducer Weight

The weight chart of butt weld reducer is covering the size from 3/4 inch to 24 inch, and available in Schedule 20, STD, 40, 80, 120, 160.

Inspection of ASTM A403 WP316 Concentric Reducer

Inspection

1. Visual the surface of Concentric Reducer body. Such as dents, die marks, porosity, undercuts etc.
2. Check the marking. Such as size, material code, material grade, thickness, heat no.
3. Measure the size. Such as large and small end diameter, thickness, height of end to end.
