Haihao Group is pleased to announce that a domestic shipyard recently purchased a batch of high-quality pipe fittings from Haihao Group, including ASME B16.9 A403-WP304L SMLS tees. These pipe fittings are used in ship piping systems, with sizes ranging from DN80 to DN300. ASME B16.9 A403-WP304L SMLS tee is a key component to ensure the reliability and efficiency of the shipboard piping system.
ASME B16.9 A403 WP304L SMLS tees
Ship piping systems demand pipe fittings that can withstand harsh marine environments and rigorous operational conditions. The ASME B16.9 A403-WP304L SMLS tee is designed to meet these stringent requirements. These tees are manufactured seamlessly (SMLS), meaning they are formed from a single piece of metal without any welded joints. This seamless construction provides superior strength and integrity, essential for the high-pressure and high-stress conditions found in marine applications.
The ASME B16.9 A403-WP304L SMLS tee is made from A403-WP304L stainless steel, a material known for its excellent corrosion resistance and mechanical properties. The chemical composition of A403-WP304L includes a low carbon content, which enhances its weldability and reduces the risk of carbide precipitation during welding. The main components of A403-WP304L are:
Carbon (C): ≤ 0.03%，Chromium (Cr): 18.0 – 20.0%，Nickel (Ni): 8.0 – 12.0%，Manganese (Mn): ≤ 2.0%，Silicon (Si): ≤ 0.75%，Phosphorus (P): ≤ 0.045%，Sulfur (S): ≤ 0.03%
These elements work together to provide the ASME B16.9 A403-WP304L SMLS tee with its outstanding corrosion resistance, especially in chloride-rich environments typically found in marine settings. The low carbon content in A403-WP304L helps prevent sensitization and intergranular corrosion, which are crucial factors in maintaining the integrity of ship piping systems.
The mechanical properties of the ASME B16.9 A403-WP304L SMLS tee include:
Tensile Strength: ≥ 485 MPa，Yield Strength: ≥ 170 MPa，Elongation: ≥ 40%
These properties ensure that the ASME B16.9 A403-WP304L SMLS tee can withstand the mechanical stresses and pressures encountered in shipboard operations. The high tensile and yield strength, combined with excellent elongation, make these tees suitable for dynamic and static loads in ship piping systems.
In addition to its mechanical robustness, the ASME B16.9 A403-WP304L SMLS tee offers superior corrosion resistance, an essential feature for components exposed to seawater and humid marine atmospheres. The high chromium and nickel content in the alloy forms a passive oxide layer on the surface, protecting the material from rust and corrosion. This makes the ASME B16.9 A403-WP304L SMLS tee particularly suitable for long-term use in ship piping systems, where reliability and durability are paramount.
