Seamless Carbon Steel Pipe Reducer Suppliers in China - Concentric & Eccentric Factory, ASME B16.9

A pipe reducer is an essential fitting used to connect pipes of varying diameters within a pipeline system. This component facilitates a smooth transition between different pipe sizes, effectively regulating flow speed and pressure by altering the fluid channel area. For instance, it enhances flow from larger to smaller diameters while slowing it down from smaller to larger diameters. Additionally, pipe reducers accommodate discrepancies in equipment interfaces and optimize pipeline layouts to mitigate resistance or stress caused by abrupt diameter changes. The two main types are concentric and eccentric reducers, which find extensive application in 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 trusted supplier and factory based in China, we offer high-quality pipe reducers designed to meet various industrial needs, ensuring reliability and performance for your pipeline systems

    Frequently Asked Questions
    Q What material grades are available for carbon steel 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 piping applications.
    Q Which stainless steel grades do you supply for pipe fittings?
    We supply stainless steel pipe fittings in ASTM A403 grades including WP304, WP304L, WP316, WP316L, WP321, and WP347, covering standard and low-carbon variants 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 conforming to 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, designed for high-temperature and high-pressure piping systems in power generation and petrochemical industries.
    Q What surface treatment options are available for pipe fittings?
    We offer four standard surface treatment options: anti-rust oil, black paint, electric galvanized, and hot-dip galvanized. These treatments help protect the fittings from corrosion during storage, transportation, and installation.
    Q Which surface treatment is recommended for outdoor or harsh environments?
    Hot-dip galvanizing is generally recommended for outdoor or harsh environments due to its thicker zinc coating and superior long-term corrosion resistance compared to electric galvanizing or anti-rust oil treatments.
