Stainless Steel Concentric Reducer is manufactured according to ASME B16.9, American standard for buttweld pipe fittings.

Stainless steel buttweld fittings is known for the high strength, excellent corrosion withstand and long service life. They are suit for air, water, oil and natural gas applications. Schedule of buttweld fittings refers to the wall thickness, higher schedule pipe fittings can bear higher pressure. Sch 10s, Sch 40 and Sch 80 pipe reducer is more common.

Zizi is manufacture, exporter of ASME butt weld pipe fittings, we have stainless steel 316 reducers in stocks and offers 5” x 3” Sch10S Concentric reducer A403 WP316 for Singapore with best price.

Pipe Reducer Catalogue

Stainless Steel pipe reducer can be divided into concentric reducer and eccentric reducer.

Concentric reducer is symmetrical, the center of two end are on the same line, while eccentric reducer is not symmetrical and usually used in the vertical pipeline.

According to the manufacturer technique, it also divided into seamless reducer and welded reducer. Large diameter reducer often is welded in order to save cost.

Based on their materials, there are stainless steel reducer, carbon steel reducer or alloy steel reducer.

Zizi is manufacturer of copper nickel pipe fittings include concentric reducer, nipple, 90° Elbow, Equal and Reducing Tee, Cap, Coupling, Bushing and Union.

C71500 is a commonly used copper nickel alloy with good corrosion resistance, copper nickel C71500 pipe fittings is very suitable for marine industries. Copper nickel concentric reducer has beautiful golden appearance because of the high content of copper.

We have various copper nickel pipe fittings in stocks and export 10” x 12” sch 80 C71500 concentric reducer to South Africa.

What is Copper Nickel C71500?

Copper nickel C71500 is also know as Copper Nickel (70/30), offers extraordinary resistance to corrosion and stress corrosion cracking, as well as moderate strength, workability and weld-ability. The chief composition is copper, and it also contains 30% nickel and  limited additions of manganese and iron.

More details for wrought copper nickel C71500 is defined in ASTM A466 and ASME SB466.

Recently we supplied 10” x 8” sch 40 concentric reducer ASTM A420 WPL6 ASME B16.9 to Malaysia. Those pipe reducers are all qualified by ISO manufacturer and attached with MTC. The material ASTM A420 WPL6 are sourced from a long-term cooperative formal factory.  We set the most reasonable price as well based on the high quality requirement.

We also manufacture and export other butt weld fittings such as 90 Degree Elbow, 45 Degree Elbow, Equal Tee, Reducing Tee Pipe Cap and Stub End.

Package of ASME B16.9 Concentric Reducer

• The 10” x 8” concentric reducer is packed into wooden cases with plastic film wrapped.
• The pipe reducers larger than 16” are packed on wooden pallet.

Types of Pipe Reducer

Pipe reducers are only available in buttweld end. There are two main types of pipe reducer: concentric and eccentric reducer.

According to the form material, it also can be divided into seamless reducer and welded reducer.

Q&A for Concentric Reducer ASTM A420 WPL6

What is ASME B16.9 Conc Reducer?

ASME B16.9 is the fabricate standard for butt weld fittings.

Pipe reducer is buttweld pipe fitting. It is a short section of pipe with two outlet in different sizes. Usually the outlets are round. It is used to reduce the diameter of pipeline so that named as reducer. The center of the concentric reducers’ outlets is on the same line.

ASME B16.9 Concentric Reducer

What is ASTM A420 WPL6?

ASTM A420 WPL6 is one kind of low temperature carbon steel (LTCS). It is a material for buttweld fittings with good performance at low temperature service. ASTM A420 also covers carbon steel and alloy steel for low temperature service wrought fittings.
