What we make today
Stainless Steel Elbow
We manufacture high-precision stainless steel elbows—including 45°, 90° long radius, and 90° short radius configurations—engineered to change flow direction seamlessly in industrial piping systems. Produced in compliance with ASME B16.9 and JIS standards using premium 304 and 316L grades, our elbows deliver exceptional corrosion resistance and pressure tolerance for chemical, oil and gas, and water treatment applications.
Stainless Steel Reducer
Our stainless steel reducers, available in concentric and eccentric designs, provide smooth pipe-size transitions while maintaining optimal flow control and minimizing system turbulence. Engineered to ASME B16.9 and DIN specifications, these fittings are precision-machined to handle demanding high-pressure environments across industrial manufacturing and processing facilities.
Stainless Steel Tee
S&S manufactures equal and reducing stainless steel tees designed to split or combine fluid flow with maximum structural integrity. Conforming to ASME B16.9 and ASTM A403 global standards, our tees feature uniform wall thickness and superior weldability, ensuring leak-free performance in high-stress industrial piping networks.
Stainless Steel Cap
Designed to securely seal pipe ends and pressure vessel openings, our heavy-duty stainless steel caps protect piping systems against leaks, contamination, and pressure loss. Built to ASME B16.9 specs, these end-caps offer maximum durability, extreme temperature resistance, and long-term reliability for critical process industries.
Stainless Steel Stub End
Our Type A and Type B stainless steel stub ends are manufactured for seamless integration with lap joint flanges, allowing for easy inspection and cost-effective piping alignment. Made from high-grade stainless steel to meet ASME B16.9 standards, they provide flexible, corrosion-resistant connections ideal for systems requiring frequent maintenance.
