Reliable Blind Flange Manufacturer in India Offering Carbon Steel, Alloy Steel & Stainless Steel Blind Flanges in ASTM A105, A350 LF2, A182 F304, F316, F11 & F22 Grades

Peekay Metal Corporation is a leading Blind Flange Manufacturer in India, offering robust and precision-crafted solutions for critical industrial systems. Blind flanges are solid discs used to isolate or terminate piping systems, ensuring complete shut-off where necessary. They are essential in pressure vessel openings, testing lines, and maintenance operations, providing a secure seal without allowing flow through. With their ability to withstand extreme pressure and prevent leakage, blind flanges play a vital role in systems across industries like oil & gas, petrochemical, power generation, and water treatment. We provide Weld Neck Flanges, engineered for strength, durability, and leak-proof performance.

As a trusted Blind Flange supplier in India, we provide a wide variety of blind flanges in different materials, pressure classes, and sizes to meet diverse application requirements. Our blind flanges are manufactured using high-quality stainless steel, carbon steel, and alloy steel, ensuring durability, corrosion resistance, and long service life. Each flange undergoes strict quality checks to comply with international standards. Whether used for sealing off unused pipeline sections or providing access for future expansion, our blind flanges deliver reliability and performance you can count on.

Blind flanges are flat flanges having no bore, and their purpose is to close the end of pipelines, valves or pressure vessels in the safest and most reliable manner possible. They find wide applications in those industries where they are in need of frequent inspection, pressure testing or temporary isolating flow. The blind flanges will prevent leakage, preserve downstream equipment, and also enable easy access to the system later in case of expansion or modification of the entire pipeline without necessarily dismantling the entire pipeline.
Blind flanges have a very diverse variety of materials, including carbon steel, alloy steel, stainless steel, and duplex steel, and they can be used in high pressure as well as extreme-temperature applications. Their strong construction provides them with high resistance to mechanical and corrosion stress and long-term deformation. Blind flanges are available in different pressure classes and international standards and provide a reliable way to use any critical piping system in the oil and gas, as well as petrochemical, power and process sectors.

Client Project Summary of Blind Flange Exporter in India

The client project deals with the provision of high-quality Blind Flanges to be used in the critical piping systems in industries that have high pressure and temperature environments. These blind flanges were made of high-quality carbon steel, alloy steel, stainless steel and were made according to the ASTM and ASME specifications to guarantee high strength, dimension, and performance, and long life. Tough quality control processes were addressed in all the manufacturing steps such as checking of raw materials, checking of dimensional, checking of pressure rating, and mechanical property tests. The project was done on time and provided safe, reliable and leak-proof closure solutions to key industrial operation.
