Seamless Carbon Steel Concentric and Eccentric Pipe Reducers - China Suppliers & Factory – ASME B16.9

A pipe reducer serves as an essential fitting for connecting pipes of different diameters within pipeline systems. This component smoothly transitions between varying pipe sizes, allowing for efficient fluid flow management. By altering the fluid channel area, it regulates flow speed and pressure—accelerating flow from larger to smaller diameters and decelerating it from smaller to larger diameters. This adaptability is crucial for accommodating different equipment interfaces and balancing pipeline configurations, ultimately preventing resistance or stress from abrupt changes in diameter, Our pipe reducers come in two primary types: concentric and eccentric, widely utilized across industries such as chemical, construction, and petroleum, **Quick Details Table**, | **Product Types** | Bw concentric & eccentric Reducer |, |------------------------|---------------------------------------------|, | **Outside Diameter** | 1/2~60 (DN15~DN1500) |, | **Thickness** | SCH5s, SCH10s, SCH40, SCH80 |, | **Standards** | ASME B16.9, MSS SP-75, DIN 28011, JIS B 2312, EN10253-2 |, As a leading manufacturer and supplier in China, we pride ourselves on delivering high-quality pipe reducers directly from our factory.

    Frequently Asked Questions

    Q What carbon steel grades are available for pipe fittings?
    Our carbon steel pipe fittings are available in ASTM A234 WPB and WPC grades, as well as ASTM A420 WPL9, WPL3, and WPL6 grades, suitable for a wide range of industrial and low-temperature applications.
    Q Which stainless steel grades do you supply?
    We supply stainless steel pipe fittings conforming to ASTM A403, including WP304, WP304L, WP316, WP316L, WP321, and WP347 — covering standard, low-carbon, and stabilized grades for corrosion-sensitive environments.
    Q Do you offer Duplex and Super Duplex Stainless Steel fittings?
    Yes. We provide Duplex and Super Duplex Stainless Steel fittings per ASTM A815, including UNS S31803 (Duplex 2205), UNS S32750 (Super Duplex 2507), and UNS S32760, ideal for highly corrosive and high-pressure service conditions.
    Q What alloy steel grades are available?
    Our alloy steel pipe fittings are manufactured to ASTM A234 in grades WP1, WP12, WP11, WP22, WP5, WP9, and WP91, making them suitable for high-temperature and high-pressure piping systems in power generation and petrochemical industries.
    Q What surface treatment options are available?
    We offer four surface treatment options: anti-rust oil for temporary corrosion protection during storage and transit, black paint for basic surface protection, electric galvanized for a uniform zinc coating, and hot-dip galvanized for heavy-duty long-term corrosion resistance.
    Q Which surface treatment is recommended for outdoor or harsh environments?
    Hot-dip galvanizing is generally recommended for outdoor or harsh environments, as it provides a thicker and more durable zinc coating compared to electric galvanizing, offering superior long-term corrosion resistance.
