MS Lap Joint Flanges Available in Following Metals & Grades

Mild Steel

Our MS Lap Joint Flanges are designed for piping systems that require frequent dismantling or precise bolt alignment. Functioning as a loose backing flange, it slides over a stub end (which is welded to the pipe), allowing the flange to rotate freely for easy bolt hole matching. As a specialized MS Lap Joint Flanges Manufacturer in Mumbai and Maharashtra, we fabricate these from high-quality Mild Steel, offering a cost-effective solution for low-pressure applications. These flanges are ideal for water lines and non-corrosive fluids where stainless steel is not required. Choose a trusted MS Lap Joint Flanges Supplier in India for reliable, economical piping components that meet international standards.

Benefits and Application of MS Lap Joint Flanges

Simplified Bolt Alignment: The flange rotates freely around the stub end, allowing the bolt holes to align perfectly with the mating flange without having to rotate the pipe itself.

Cost-Effective Solution: Made from Mild Steel, these flanges offer a significant price advantage over stainless steel for non-corrosive applications like water distribution and structural plumbing.

Easy System Maintenance: Since the flange is not welded to the pipe, the connection can be quickly disassembled for cleaning, inspection, or replacement of gaskets.

Some FAQ


What is the primary advantage of using an MS Lap Joint Flange?	The main advantage is the ability to swivel around the pipe, which simplifies bolt alignment and eliminates fit-up difficulties during installation.
Are you an MS Lap Joint Flanges Supplier in Mumbai?	Yes, we are a leading supplier in Mumbai with ready stock to fulfill orders across Maharashtra and India efficiently.
Do I need a stub end to use with this flange?	Yes, a Lap Joint flange must be used with a stub end (collar), which is welded to the pipe while the flange remains loose behind it.
Do MS Lap Joint flanges rust?	Yes, mild steel will rust if untreated. We supply them with a coating of red oxide paint or oil to provide protection during storage and transport.
What sizes do you manufacture?	We manufacture standard sizes ranging from 1/2" NB to 24" NB, and we can also fabricate larger custom sizes upon request.
Can these flanges be used for high-pressure systems?	They are typically used for low-to-medium pressure applications (Class 150 or 300) because they have lower fatigue strength than weld neck flanges.
Do you provide Mill Test Certificates?	Yes, we provide Mill Test Certificates (MTC) with our supplies to verify the quality and grade of the mild steel used.
Is welding required for the flange itself?	No, the flange itself is not welded. Only the stub end is welded to the pipe, which prevents the flange from contacting the fluid directly.
