A steel pipe reducer is the component in a pipeline that decreases the pipe size to a smaller bore. There are two main types of reducer: concentric and eccentric reducer. Some pipe reducers are manufactured by means of punch forming and others by bending, extruding, pushing, molding or machining.
The steel pipe reducer is used when liquid flow increases or decreases in small quantities. In order to prevent cavitation, it is also used to connect to the inlet hole of pump. Besides, it is also useful to connect joints in instrument like flow meter and control valve. The steel reducer also finds applications in sugar mills and distilleries, مضخات, البتروكيماويات, cement and construction industries and steel plants. It can be stored in fumigation-free boxes or wooden holders.

What’s the difference between CONCENTRIC REDUCER و ECCENTRIC REDUCER ?
CONCENTRIC REDUCER
The open ends of a concentric reducer are aligned and centered one to the other. عمومًا, this type of pipe reducer is used to modify the bore size of the pipeline by two (maximum three) measures, to avoid an excessive pressure drop in the pipeline.
If a larger reduction is needed, then a sequence of reducers shall be used to have a smooth and gradual adjustment of the pipeline bore size (vs. a drastic change).
For small bore size reductions, reducing flanges may be an alternative to buttweld reducers.
ECCENTRIC REDUCERThe open ends of an eccentric reducer are in an “offset” position one to the other.
Eccentric reducers are used, generally, for pipelines installed in a horizontal position (whereas concentric reducers are used for pipelines installed vertically or for the inlets of suction pumps, as top flat eccentric reducers).
PIPE REDUCERS MANUFACTURING PROCESS
CONCENTRIC VS ECCENTRIC REDUCER
The key difference between concentric vs eccentric reducer is the centricity of the inlet vs. the outlet of the fitting, which is perfect for a concentric reducer and offset of an eccentric reducer.
BW REDUCER MANUFACTURING PROCESS
Cold forming is the most common manufacturing process for seamless eccentric/concentric reducers (welded reducers are produced with the single or double seam weld process):
Pipe fittings are used in plumbing systems to connect straight sections of pipe or tubes, to accommodate different sizes or shapes, and for other purposes such as regulating (or measuring) fluid flow. These fittings are used in plumbing systems to control the transfer of water, gas or liquid waste within pipes or plumbing systems in domestic or commercial environments. تركيبات (especially uncommon types) require money, time, materials and tools to install and are an important part of plumbing and plumbing systems. Common pipe fittings mainly include: شفة, elbows, couplings, unions, spools, reducers, bushings, tees, diverter tees, crosses, قبعات, plugs, barbs and valves. Although valves are technically fittings, they are usually discussed separately.
