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, Pam, petrokimia, 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 dan ECCENTRIC REDUCER ?
CONCENTRIC REDUCER
The open ends of a concentric reducer are aligned and centered one to the other. Secara amnya, 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. Kelengkapan (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: bebibir, elbows, couplings, unions, spools, reducers, bushings, tees, diverter tees, crosses, topi, plugs, barbs and valves. Although valves are technically fittings, they are usually discussed separately.
Badan pemasangan paip biasanya diperbuat daripada bahan asas yang sama dengan paip atau tiub yang disambungkan: Tembaga, keluli, PVC, CPVC atau ABS. Sebarang bahan yang dibenarkan oleh paip, kesihatan atau kod bangunan (mengikut mana yang berkenaan) boleh digunakan, tetapi ia mesti serasi dengan bahan lain dalam sistem, cecair yang disalurkan, dan suhu dan tekanan di dalam (dan luar) sistem. Kelengkapan tembaga atau gangsa di atas kuprum Biasa dalam sistem paip dan paip. Ketahanan api, rintangan kejutan, kekuatan mekanikal, anti-kecurian dan faktor lain juga mempengaruhi pilihan bahan untuk kelengkapan paip.

Kelengkapan silang membolehkan percabangan paip, membolehkan pengagihan air atau cecair lain ke pelbagai lekapan atau kawasan. Mereka biasanya digunakan dalam sistem bekalan air, sistem pengairan, dan sistem pemanasan.
Butt Weld Cap Kami adalah pengeluar butt weld cap dan membekalkan semua jadual dalam jenis bahan seperti keluli karbon, keluli tahan karat, keluli aloi. Zizi menghasilkan penutup paip di ASME, DARI, JIS dan piawaian lain yang diperlukan. Penutup paip adalah salah satu kelengkapan paip yang biasa digunakan untuk menghentikan bendalir dengan menutup di hujung paip. Ia boleh didapati dalam jenis kimpalan punggung, jenis kimpalan soket dan jenis berulir, dan topi buttweld lebih popular memandangkan prestasi yang baik, sambungan yang stabil dan julat pemilihan dimensi yang besar.
