Pipe Reducers are the component in a pipeline that reduces the pipe size from a larger to a smaller bore (inner diameter).
We produce pipe creducer include oncentric reducers, eccentric Reducers, seamless or welded, with dimensions and tolerances according to Asme/Ansi B16.9 and EN 10253-4
Standard: ANSI B16.9 / 16.28, ASTM A53/A106, API 5L, ASME B36.10M---1996, DIN2605 / 2615 / 2616, JIS P2311/2312
Surface treatment: Transparent oil, rust-proof black oil or hot galvanized.
Welded pipe fittings are made as per ASME spec B16.9. ASME B16.9 covers factory made wrought steel butwelding fittings in sizes 1/2" to 48". This standard however does not cover low pressure corrosion resistant buttwelding fittings. See MSS SP-43, Wrought Stainless Steel Butt-Welding Fittings.
A234 WPB is the most common material used for carbon steel butt welded fittings.ASTM A234 WPB is the Standard Specification for Piping Fittings of Wrought Carbon Steel and Alloy Steel for Moderate and High Temperature Service.

Tensile Requirements
Even welding and smooth weld line, can be substitute for seamless tube after drawing and cold rolling.
This Standard covers overall dimensions, tolerances, ratings, testing, and markings for wrought factory-made buttwelding fittings in sizes NPS 1 ⁄ 2 through 48 (DN 15 through 1200).
Fittings may be made to special dimensions, sizes, shapes, and tolerances by agreement between the manufacturer and the purchaser.
Abrasion resistant material:Ceramic lined, Ceramic tile lined , Bi-metal clad pipe
Reducers are usually concentric but eccentric reducers are used when required to maintain the same top-or bottom-of-pipe level.
A reducer can be used either as nozzle or as diffuser depending on the mach number of the flow.
A reducer allows for a change in pipe size to meet hydraulic flow requirements of the system, or to adapt to existing piping of a different size.
Special design available All the production process are made according to ISO9001:2000 strictly.
