MS Socket Weld Flanges Available in Following Metals & Grades

Mild Steel

Our MS Socket Weld Flanges are engineered for secure connections in small-bore piping systems where high pressure and structural strength are required. Unlike slip-on flanges, these feature a recessed socket where the pipe is inserted and fillet-welded on the outside, ensuring a strong, leak-proof joint. As a leading MS Socket Weld Flanges Manufacturer in Mumbai and Maharashtra, we use high-quality Mild Steel to ensure durability and weldability. These flanges are ideal for hydraulic and steam lines where flow restriction must be minimized. Choose us as your trusted MS Socket Weld Flanges Supplier in India for precision-engineered components that meet international standards.

Benefits and Application of MS Socket Weld Flanges

Superior Joint Strength: The socket design offers static strength equal to slip-on flanges but with significantly higher fatigue resistance, making it ideal for systems with vibration.

Simplified Alignment: The pipe inserts directly into the socket recess, automatically aligning it and eliminating the need for tack welding or special clamping fixtures.

Cost-Effective Durability: Manufactured from Mild Steel, these flanges provide a robust and economical solution for high-pressure non-corrosive applications compared to stainless steel.

Some FAQ


What is the main purpose of an MS Socket Weld Flange?	It is designed for small-bore piping (typically up to 4 inches) in high-pressure systems to provide a strong, leak-proof connection with good fatigue strength.
Are you an MS Socket Weld Flanges Supplier in Mumbai?	Yes, we are a Mumbai-based supplier with a comprehensive stock of mild steel flanges ready for immediate delivery across Maharashtra and India.
Why is an expansion gap necessary in the socket?	A gap of approximately 1/16 inch (1.6mm) is required between the pipe end and the socket bottom to allow for thermal expansion during welding.
Do MS Socket Weld flanges rust?	Yes, mild steel is susceptible to rust. We supply them with a protective coating of red oxide paint or oil to prevent corrosion during storage and transit.
What sizes do you manufacture?	We specialize in manufacturing sizes from 1/2" NB to 4" NB, as socket weld flanges are generally not used for larger diameters due to stress factors.
Can these flanges be used for high-pressure applications?	Yes, they are suitable for high-pressure ratings (up to Class 1500 or higher) and provide a more reliable seal than threaded flanges in vibrating systems.
Do you provide Mill Test Certificates?	Yes, we provide Mill Test Certificates (MTC) with our supplies to verify the chemical composition and mechanical properties of the mild steel.
How is the flange welded to the pipe?	The pipe is inserted into the socket, withdrawn slightly to create the expansion gap, and then a single fillet weld is applied around the hub on the outside.
