Piyush Steel is a trusted ASME B16.9 concentric butt-weld reducer manufacturer in India, offering a complete range of pipe fittings designed to meet global industrial standards. A concentric butt-weld reducer is used to connect pipes of different diameters while keeping the centerline consistent, ensuring a balanced flow. These fittings are essential in vertical piping, pump discharge lines, and gravity-fed systems, where uniform pressure and fluid alignment are necessary. Each fitting is produced in accordance with ASME B16.9 dimensions, ensuring high precision and compatibility with international piping systems.
Our concentric butt-weld reducers are available in various material grades to suit different process conditions. We supply stainless steel concentric reducers (304, 304L, 316, 316L), carbon steel reducers, alloy steel reducers (ASTM A234 WP11, WP22), and Duplex/Super Duplex concentric reducers for enhanced corrosion resistance and strength. These reducers are designed to perform reliably in applications involving high pressure, temperature fluctuations, and corrosive media. All fittings comply with ASME/ANSI standards and are manufactured with strict quality control, making them suitable for industries such as oil & gas, petrochemicals, power plants, and marine systems.
Table Of Content
Piyush Steel offers pipe size transition fittings in a wide range of sizes, starting from ½" NB up to 48" NB, with wall thicknesses from SCH 10 to SCH XXS. The reducers are available in both plain-end and beveled-end configurations, ready for welding. Butt weld reducer stainless steel variants are particularly suitable for food processing, chemical plants, and desalination projects due to their excellent corrosion resistance. For power and structural projects, carbon steel concentric reducers and alloy steel reducers provide the mechanical strength required for demanding environments. All reducers are supplied with Mill Test Certificates (MTC), and third-party inspection can be arranged on request.
One of the key benefits of using an ASME B16.9 concentric reducer is its symmetrical shape, which promotes even flow and reduces turbulence. This makes it ideal for vertical pipelines and tank inlet reducer fittings, where maintaining centerline flow is important. Concentric reducers are preferred in applications requiring uniform pressure distribution, while eccentric reducers are better for horizontal lines to prevent air accumulation. We also offer technical guidance to help clients choose the right reducer for their specific system needs.
With a large inventory and ready stock of high-pressure concentric butt-weld reducers, Piyush Steel is capable of meeting bulk orders and urgent project demands. We test our fittings for dimensional accuracy, pressure performance, and surface finish. As a leading ASME B16.9 reducer supplier in Mumbai, we cater to clients across India and export to countries in the Middle East, Southeast Asia, and Europe. Whether your requirement is for butt-weld concentric reducers in stainless steel, carbon steel, or alloy grades, we deliver quality you can trust with timely delivery and competitive pricing.
