Reducers Fittings Size Chart

Reducers Fittings Dimension Chart (ASME B16.9)

Dimension H is the overall length of the reducer, and ASME B16.9 sets it by the large end size. The small end can be any standard size within that range. All dimensions are in mm.

Wall thickness follows the schedule of each connecting pipe, so we mark both end walls on the order. An 8" × 6" Sch 40 reducer, for example, carries an 8.18 mm wall on the large end and a 7.11 mm wall on the small end.

Reducer Fittings Grades We Supply

As a reliable Reducer Fittings Supplier, We offer a wide range of material grades to suit different fluid types, operating temperatures, pressure conditions, and industrial applications. We supply reducer fittings in carbon steel, alloy steel, stainless steel, duplex steel, and nickel alloys to meet diverse piping requirements.

• Carbon Steel Reducers: ASTM A234 WPB is widely used in oil, water, steam, and gas piping systems. We also supply ASTM A420 WPL6 for low-temperature applications and high-yield grades under MSS SP-75 for suitable pipeline requirements.
• Alloy Steel Reducers: ASTM A234 WP11, WP22, and WP91 are suitable for high-temperature applications in power plants, refineries, and industrial processing facilities.
• Stainless Steel Reducers: ASTM A403 WP304, WP304L, WP316, WP316L, WP321, and WP347 are used in applications requiring corrosion resistance and durability.
• Duplex and Super Duplex Reducers: ASTM A815 UNS S31803, S32205, and S32750 grades are suitable for demanding environments, including seawater handling and offshore applications.
• Nickel Alloy Reducers: Inconel, Monel, and Hastelloy grades are available for specialized applications involving aggressive chemicals, corrosion, and demanding operating conditions, subject to specifications and availability.

We help customers select suitable reducer fitting grades based on application requirements, relevant material standards, and project specifications.

Reducer Fittings Standards and Certifications

Reducer fittings are manufactured according to applicable industry standards to meet the dimensional, material, and performance requirements of industrial piping systems. Common standards include ASME B16.9 for butt-weld concentric and eccentric reducers, MSS SP-43 for light-wall stainless steel fittings, MSS SP-75 for high-yield pipeline fittings, and MSS SP-95 for swage nipples. Material specifications include ASTM A234 for carbon and alloy steel, A403 for stainless steel, A420 for low-temperature steel, A815 for duplex steel, and B366 for nickel alloy fittings. ASME B16.25 covers weld-end preparation.

As a reliable Reducers Fittings Supplier in India, we support quality assurance through ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certifications, along with applicable PED 2014/68/EU requirements. Documentation can include EN 10204 3.1 Mill Test Certificates, chemical and mechanical test reports, dimensional inspection reports, and Positive Material Identification (PMI) reports. EN 10204 3.2 certification and third-party inspections can also be arranged according to project requirements and availability.

Reducers Fittings Applications

• Pump Suction and Discharge Lines: An eccentric reducer fitting with the flat side up keeps air out of the pump suction, while a concentric reducer handles the discharge side.
• Oil and Gas Pipelines: Reducers fittings step the line down at metering skids, valve stations and delivery points.
• Refineries and Petrochemical Plants: Alloy steel reducers join large process headers to smaller equipment nozzles.
• Power Plants: WP22 and WP91 reducers carry steam and boiler feed through changes in line size at high temperature and pressure.
• Chemical Processing: Stainless steel 316L and duplex reducers connect large transfer lines to smaller reactors and dosing units.
• Pharmaceutical and Food Plants: Polished stainless steel reducers give smooth, easy-to-clean transitions in hygienic piping.
• Water Treatment and Desalination: Super duplex and 316L reducers join large brine and seawater mains to smaller treatment units.
• Pipe Racks and Drain Lines: Flat-on-bottom eccentric reducers keep rack lines level and let liquid drain, and many projects source them from a Reducers Fittings Supplier in India like us.
• Fire Protection and HVAC: Carbon steel reducers step down from large risers and chilled water mains to branch and coil connections.
• Shipbuilding and Offshore: Compact reducers join seawater cooling and fire fighting lines of different sizes on vessels and platforms.

Reducers Fittings Manufacturing Capacity and Export Capability

Our Vasai facility, near Mumbai, can manufacture up to 100 tons of reducers fittings every month. We form concentric and eccentric reducers from 1/2" to 24" NB on the large end, in carbon, stainless, duplex and alloy grades. Forming, heat treatment and machining all happen in one plant, which keeps lead times short and lets us combine grades and size pairs in a single order.

We can also export up to 100 tons every month, from one carton of samples to full container loads. We book cargo through Nhava Sheva (JNPT) and Mundra, and our team prepares every export document in-house, so shipments reach 85+ countries without delay at the port.
