Stainless Steel 316

Our SS 316 Stub End Fittings are butt-weld components designed to work in conjunction with Lap Joint Flanges, creating a flexible and cost-effective connection. The stub end is welded to the pipe, while the backing flange remains loose, allowing for easy rotation and alignment. As a specialized SS 316 Stub End Fittings Manufacturer in Mumbai and Maharashtra, we utilize marine-grade Stainless Steel 316 to ensure superior resistance to chlorides and pitting in aggressive environments. These fittings are ideal for systems requiring frequent maintenance or quick disassembly. Choose us as your trusted SS 316 Stub End Fittings Supplier in India for high-quality, corrosion-resistant piping solutions.

Benefits and Application of SS 316 Stub End Fittings

Marine-Grade Durability: Manufactured from SS 316, the wetted surface offers exceptional resistance to salt water and chemical corrosion, ensuring longevity in harsh conditions.

Cost Optimization: By using a high-grade SS 316 stub end with a lower-cost carbon steel backing flange, you achieve the required corrosion resistance at a fraction of the total cost.

Simplified Installation: The rotating backing flange eliminates bolt-hole alignment issues, significantly reducing installation time and effort in complex piping systems.

Some FAQ


What is the function of an SS 316 Stub End?	It provides a flanged connection point where the actual sealing surface is made of corrosion-resistant SS 316, while the bolting force is applied by a separate backing flange.
Are you an SS 316 Stub End Fittings Supplier in Mumbai?	Yes, we are a Mumbai-based supplier with a comprehensive stock of marine-grade stub ends to support projects across Maharashtra and India.
Why choose SS 316 over SS 304 for stub ends?	SS 316 contains molybdenum, which offers far superior resistance to chlorides, acids, and marine environments compared to SS 304.
What is the difference between Short Pattern and Long Pattern?	Short Pattern stub ends are compact and used with lower pressure flanges, while Long Pattern stub ends are longer to accommodate heavier backing flanges.
Can I use a Carbon Steel flange with an SS 316 Stub End?	Yes, this is the primary advantage. The SS 316 stub end handles the corrosive fluid, while the cheaper carbon steel flange handles the mechanical load.
Do you provide Mill Test Certificates?	Yes, we provide Mill Test Certificates (MTC) as per EN 10204 3.1 with every order to verify the material chemistry and mechanical properties.
Is welding required for installation?	Yes, the stub end must be butt-welded to the pipe end. The backing flange is slipped onto the pipe before this welding takes place.
What sizes do you manufacture?	We manufacture SS 316 stub ends in sizes ranging from 1/2" NB to 24" NB and can also fabricate custom sizes for specific project requirements.
