SS 316 Weld Neck Flanges Available in Following Metals & Grades

Stainless Steel 316

Our SS 316 Weld Neck Flanges are engineered for critical high-pressure and high-temperature piping systems. Featuring a long tapered hub, this design transfers stress from the flange to the pipe, providing structural reinforcement and reducing turbulence. As a premier SS 316 Weld Neck Flanges Manufacturer in Mumbai and Maharashtra, we utilize marine-grade Stainless Steel 316 to ensure exceptional resistance to chlorides and acidic corrosion. These flanges are butt-welded to the pipe, making them ideal for hazardous applications. Choose us as your trusted SS 316 Weld Neck Flanges Supplier in India for durable, leak-proof connections that meet global ASME and ASTM standards.

Benefits and Application of SS 316 Weld Neck Flanges

Enhanced Structural Integrity: The tapered hub design reinforces the flange, distributing stress evenly to the pipe and preventing dishing under high pressure or vibration.

Superior Corrosion Resistance: Made from Stainless Steel 316, these flanges offer excellent protection against pitting in chloride environments and marine atmospheres compared to SS 304.

Unrestricted Flow: The flange bore matches the pipe ID, ensuring smooth fluid flow with minimal turbulence and erosion, which is crucial for sensitive process lines.

Some FAQ


What is the main advantage of a Weld Neck Flange over a Slip-On Flange?	Weld neck flanges have a tapered hub that provides higher strength and better stress distribution, making them safer for high-pressure applications.
Are you an SS 316 Weld Neck Flanges Supplier in Mumbai with ready stock?	Yes, we are based in Mumbai and maintain a significant inventory of standard sizes to ensure quick delivery across Maharashtra.
Do these flanges come with a specific bore size?	Yes, the bore of the flange is machined to match the inside diameter of your specific pipe schedule to ensure a smooth transition.
What implies "SS 316" in the product name?	SS 316 indicates the material is Stainless Steel Grade 316, which contains molybdenum for superior corrosion resistance in chloride environments.
Can you manufacture flanges to custom dimensions?	Yes, as a specialized SS 316 Weld Neck Flanges Manufacturer in India, we can fabricate custom sizes and schedules per client drawings.
Do you provide material test certificates?	We provide complete Mill Test Certificates (MTC) in accordance with EN 10204 3.1 with every supply to verify chemical and physical properties.
What pressure classes are available?	We supply flanges in all standard pressure classes, including 150#, 300#, 600#, 900#, 1500#, and 2500#.
How are these flanges attached to the pipe?	They are attached via a full penetration V-butt weld connecting the end of the flange hub directly to the end of the pipe.
