Engineered for the most aggressive corrosive environments, the STAINLESS STEEL SEAMLESS TEE WP316 is a premium-grade pipe fitting designed to excel where standard alloys fail. Constructed from 316 stainless steel—an austenitic alloy containing 2-3% molybdenum—this tee offers unparalleled resistance to chloride-induced corrosion, pitting, and crevice attack. Compliant with ASTM A403 standards, its seamless construction ensures uniform strength and leak-free performance, making it indispensable for industries where material reliability is non-negotiable.
Superior Corrosion Resistance: The addition of molybdenum enhances the alloy's ability to withstand harsh media, including seawater, sulfuric acid, and chloride solutions. It outperforms 304 stainless steel in marine, chemical, and pharmaceutical applications where aggressive corrosion is a constant threat.
High-Temperature Stability: With a service temperature range from -196°C to 870°C, the tee maintains its mechanical properties under thermal cycling, making it suitable for both cryogenic and high-heat environments, such as refinery crackers and chemical reactors.
Robust Mechanical Properties: Boasting a tensile strength of 500-700 MPa and excellent ductility, the tee resists deformation under high pressure (up to 20,000 PSI for small sizes) while allowing easy welding and machining.
Precision Manufacturing: Each tee undergoes rigorous testing, including radiographic inspection and chemical analysis, to ensure compliance with ASTM A403/ASME SA403 standards. The seamless design eliminates weak points, providing consistent performance across all sizes (1/8" NB to 48" NB) and wall thicknesses (SCH 5S to SCH XXS).
Marine Engineering: Used in seawater intake systems, offshore platforms, and ship hull piping, resisting chloride corrosion and biofouling.
Chemical Processing: Handles aggressive chemicals like hydrochloric acid, sodium hypochlorite, and brine in petrochemical plants and fertilizer production facilities.
Pharmaceutical & Biotechnology: Meets the stringent purity requirements of sterile environments, used in drug synthesis reactors and bioprocessing pipelines.
Desalination Plants: Ideal for high-salinity water treatment systems, where it withstands the corrosive effects of brackish water and anti-scaling chemicals.
Q: Is WP316 magnetic?
A: In its annealed state, WP316 is non-magnetic. Cold working or welding may induce slight magnetism, but it remains non-magnetic for most practical applications.
Q: How does WP316 compare to WP316L?
A: WP316L has a lower carbon content (<0.03%), which reduces the risk of intergranular corrosion during welding, making it preferable for welded structures in severe environments.
Q: Can this tee be used with hydrogen peroxide?
A: Yes, 316 stainless steel is highly resistant to oxidizing agents like hydrogen peroxide, making it a standard choice for chemical processing involving such substances.
Q: What is the expected lifespan in a coastal environment?
A: With proper maintenance, the tee can last 20+ years in coastal areas, far exceeding the lifespan of 304 stainless steel due to its molybdenum-enhanced chloride resistance. Regular rinsing with fresh water will further extend its service life.
