Equal and Reducing Butt-Welding Tee & Cross Pipe Fitting Suppliers - China Factory ASME B16.9

The Tee fitting is designed in the shape of a T and serves the essential function of connecting three pipes. It is commonly used in piping systems to split fluid flow from one pipe into two or to merge liquids from two pipes into a single outlet. This versatile fitting is perfect for various applications in plumbing and industrial systems.

The Cross fitting, distinguished by its cruciform shape, connects four pipes simultaneously. It is primarily utilized to facilitate multi-directional flow diversion or confluence of fluids among four separate pipes, making it an ideal solution for complex piping networks.

    Frequently Asked Questions
    What material grades are available for pipe fittings?
    We offer pipe fittings in Carbon Steel (ASTM A234 WPB, WPC; ASTM A420 WPL9, WPL3, WPL6), Stainless Steel (ASTM A403 WP304/304L, WP316/316L, WP321, WP347), and Alloy Steel (ASTM A234 WP1, WP5, WP9, WP11, WP12, WP22, WP91), as well as Duplex and Super Duplex Stainless Steel grades.
    What is the difference between WP304 and WP304L stainless steel?
    WP304L is a low-carbon version of WP304. The reduced carbon content in WP304L minimizes the risk of carbide precipitation during welding, making it more suitable for heavy welding applications and environments prone to intergranular corrosion.
    What surface treatments are available for pipe fittings?
    We provide four surface treatment options: anti-rust oil, black paint, electric galvanized, and hot-dip galvanized. Each treatment is selected based on the application environment and corrosion protection requirements.
    What is the advantage of hot-dip galvanized over electric galvanized?
    Hot-dip galvanizing provides a thicker and more durable zinc coating compared to electric galvanizing, offering superior corrosion resistance in harsh or outdoor environments. Electric galvanizing gives a smoother, more uniform finish and is typically used for applications requiring a better aesthetic appearance.
    Are Duplex and Super Duplex stainless steel fittings available?
    Yes, we supply Duplex and Super Duplex Stainless Steel fittings per ASTM A815, including UNS S31803 (Duplex), UNS S32750, and UNS S32760 (Super Duplex). These grades offer excellent resistance to stress corrosion cracking and pitting, ideal for demanding industrial applications.
    Which material grade is recommended for low-temperature service?
    For low-temperature service, ASTM A420 grades such as WPL3, WPL6, and WPL9 are recommended. These carbon steel grades are specifically designed to maintain toughness and impact resistance at sub-zero temperatures.
