    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 for low-temperature applications.
    Q Which stainless steel grades do you supply for pipe fittings?
    We supply stainless steel pipe fittings conforming to ASTM A403, including grades WP304/304L, WP316/316L, WP321, and WP347, suitable for a wide range of corrosive and high-temperature environments.
    Q Do you offer Duplex and Super Duplex Stainless Steel fittings?
    Yes. We provide Duplex and Super Duplex Stainless Steel fittings to ASTM A815, covering UNS S31803, UNS S32750, and UNS S32760, which are 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, covering grades WP1, WP12, WP11, WP22, WP5, WP9, and WP91, which are commonly used in high-temperature and high-pressure piping systems.
    Q What surface treatment options are available for pipe fittings?
    We offer multiple surface treatment options including anti-rust oil, black paint, electric galvanized, hot-dip galvanized, and 3LPE/3LPP coating, ensuring long-term corrosion protection for various service environments.
    Q What is the difference between 3LPE and 3LPP coating?
    3LPE (Three-Layer Polyethylene) is typically used for pipelines operating at temperatures up to 80°C, while 3LPP (Three-Layer Polypropylene) is suitable for higher operating temperatures up to 140°C. Both provide excellent anti-corrosion and mechanical protection for buried or submerged pipelines.
