MS Blind Flanges Available in Following Metals & Grades

Our MS Blind Flanges are heavy-duty solid plates used to terminate piping systems or seal nozzle openings. Unlike slip-on flanges, these have no center bore, providing a complete block to fluid flow. As a trusted MS Blind Flanges Manufacturer in Mumbai and Maharashtra, we fabricate these from high-quality Mild Steel, offering high tensile strength for pressure testing applications. They are commonly used in waterworks, firefighting, and structural projects where corrosion resistance is less critical. Choose a dedicated MS Blind Flanges Supplier in India for economical, robust sealing solutions that comply with international dimension standards.

Benefits and Application of MS Blind Flanges

Economical Sealing: Mild Steel provides a highly cost-effective solution for permanently or temporarily sealing pipe ends compared to stainless steel alternatives. Pressure Testing Utility: Due to their solid construction and high mechanical strength, these flanges are ideal for isolating sections of piping during pressure performance tests. Maintenance Flexibility: Installing a blind flange allows maintenance crews to easily unbolt the line end for future cleaning, inspection, or system expansion without cutting pipes.

Some FAQ


What is the primary function of an MS Blind Flange?	It is a solid disk used to completely block the end of a pipe or a vessel opening, stopping the flow of fluids.
Are you an MS Blind Flanges Supplier in Mumbai?	Yes, we are headquartered in Mumbai and maintain a robust inventory of mild steel flanges to serve clients across Maharashtra and India.
Do these flanges require painting?	Yes, because Mild Steel is susceptible to rust, we typically supply these flanges with a protective coat of red oxide paint or oil.
Can MS Blind Flanges be used for high pressure?	Absolutely. Their solid design makes them capable of withstanding significant internal pressure, often higher than open-bore flanges.
How do you install a blind flange?	It is bolted to a mating flange (like a Weld Neck or Slip-On) with a gasket placed in between to create a tight seal.
Do you manufacture custom sizes?	Yes, as a flexible MS Blind Flanges Manufacturer in India, we can fabricate custom thicknesses and diameters based on your drawings.
Is this flange suitable for corrosive chemicals?	No, Mild Steel is not recommended for corrosive environments. For such applications, stainless steel or coated flanges are necessary.
What standards do your flanges meet?	Our flanges are manufactured to meet global standards such as ANSI B16.5, BS 10 (Table D, E, F), and DIN specifications.
