SS 304 Socket Weld Flanges Available in Following Metals & Grades

Stainless Steel 304

Our SS 304 Socket Weld Flanges are engineered for secure, high-pressure connections in small-bore piping systems. Featuring a recessed socket design, the pipe is inserted and fillet-welded on the outside, ensuring a strong, leak-proof joint without internal welding issues. As a trusted SS 304 Socket Weld Flanges Manufacturer in Mumbai and Maharashtra, we utilize high-quality Stainless Steel 304 to provide reliable corrosion resistance and structural integrity. These flanges are ideal for steam, water, and non-corrosive chemical lines where flow restrictions must be minimized. Choose us as your preferred SS 304 Socket Weld Flanges Supplier in India for precision-made components that meet ASME B16.5 standards.

Benefits and Application of SS 304 Socket Weld Flanges

Strong Static Strength: The socket design provides static strength equal to a slip-on flange but significantly better fatigue resistance, making it suitable for vibrating systems.

Simplified Alignment: The pipe automatically aligns within the socket recess, eliminating the need for tack welding or special fixtures during installation.

Economical Performance: SS 304 offers excellent durability and oxidation resistance for standard industrial applications, providing a cost-effective solution compared to higher alloy grades.

Some FAQ


What is the primary use of a Socket Weld Flange?	They are designed for small-bore piping (usually 2 inches and below) in high-pressure systems where a strong, leak-proof joint is essential.
Are you an SS 304 Socket Weld Flanges Supplier in Mumbai?	Yes, we are a Mumbai-based supplier with extensive stock, serving industries across Maharashtra and India with quick turnaround times.
Why is an expansion gap needed inside the socket?	A 1/16 inch gap is left between the pipe end and the socket bottom to accommodate thermal expansion during welding, preventing cracking.
How does SS 304 compare to SS 316 for these flanges?	SS 304 is the standard grade suitable for most non-marine environments, while SS 316 offers higher corrosion resistance but at a higher cost.
What pressure classes do you offer for socket weld flanges?	We manufacture these flanges in pressure classes ranging from 150# to 1500#, suitable for various industrial pressure requirements.
Do you provide Mill Test Certificates?	Yes, we provide Mill Test Certificates (MTC) as per EN 10204 3.1 with all our products to guarantee material quality and compliance.
Can socket weld flanges be used for corrosive fluids?	Yes, but care must be taken as the gap in the socket can cause crevice corrosion; for highly corrosive fluids, weld neck flanges are often preferred.
What sizes are available in SS 304?	We specialize in sizes from 1/2" to 4" NB, as socket weld flanges are rarely used for larger pipe diameters due to stress factors.
