SS 304 Weld Neck Flanges Manufacturer and Supplier in India

Starting From 48Rs/Pcs

SS 304 Weld Neck Flanges Available in Following Metals & Grades

Our SS 304 Weld Neck Flanges are engineered for high-pressure applications requiring maximum structural strength and leak integrity. Featuring a distinct tapered hub, these flanges transfer stress from the flange to the pipe, preventing deformation under heavy loads or vibration. As a leading SS 304 Weld Neck Flanges Manufacturer in Mumbai and Maharashtra, we utilize high-quality Stainless Steel 304 to provide reliable corrosion resistance for standard industrial environments at a cost-effective price. These flanges are butt-welded to the pipe, ensuring unrestricted flow and reducing turbulence. Choose a trusted SS 304 Weld Neck Flanges Supplier in India for durable connections that meet global ASTM and ASME standards.

Benefits and Application of SS 304 Weld Neck Flanges

Structural Reinforcement: The tapered hub design reinforces the connection, distributing stress evenly to the pipe, which is critical for systems experiencing temperature fluctuations or vibration. Cost-Effective Durability: SS 304 offers excellent resistance to atmospheric corrosion and oxidation, making it a budget-friendly alternative to SS 316 for non-marine, high-pressure applications. Seamless Flow: The bore of the flange is machined to match the ID of the mating pipe, eliminating turbulence and erosion at the joint, which extends the life of the piping system.

Some FAQ


What is the main advantage of a Weld Neck flange?	The tapered hub provides structural reinforcement, making it the strongest flange design available, ideal for high-pressure and critical applications.
Are you an SS 304 Weld Neck Flanges Supplier in Mumbai?	Yes, we are headquartered in Mumbai and supply certified flanges to projects across Maharashtra and the rest of India.
How is this flange attached to the pipe?	It is attached via a specific "butt weld" where the beveled end of the flange hub is welded directly to the beveled end of the pipe.
Does the bore size matter for Weld Neck flanges?	Yes, the bore must match the inside diameter (schedule) of the connecting pipe to ensure a smooth transition and prevent turbulence.
Can SS 304 flanges be used in high temperatures?	Yes, SS 304 retains its strength and oxidation resistance at high temperatures, making it suitable for steam and hot gas lines.
Do you provide Mill Test Certificates?	We provide complete Mill Test Certificates (MTC) in accordance with EN 10204 3.1 with every supply to verify material chemistry and mechanics.
What is the difference between SS 304 and SS 304L?	SS 304L has a lower carbon content, which improves weldability and reduces the risk of corrosion after welding (sensitization).
What pressure ratings do you manufacture?	We manufacture SS 304 Weld Neck flanges in all standard pressure classes, from 150# up to 2500# for extreme pressure requirements.
