Harsh Flanges stands out as a top manufacturer and supplier of BLRF (Blind Raised Face) Flanges, proudly based in Mumbai, India. These flanges are designed to effectively seal the ends of piping systems, valves, or openings in pressure vessels, making them crucial for situations where isolation, pressure testing, or future expansion is necessary. Our BLRF flanges are crafted in line with international standards like ANSI/ASME B16.5, B16.47, and DIN, and come in a variety of sizes and pressure classes. Renowned for their precise dimensions, corrosion resistance, and robust structural integrity, Harsh Flanges caters to industries such as oil & gas, petrochemicals, power generation, and marine engineering.
We produce our BLRF flanges using materials like carbon steel (ASTM A105), stainless steel (A182 F304/F316), and alloy steel (F11/F22), carefully chosen based on the specific service environment. These flanges boast impressive tensile strengths of up to 550 MPa, yield strengths exceeding 250 MPa, and elongation rates of 20% or more, ensuring they are both strong and flexible. The raised face (RF) design enhances gasket compression, delivering a dependable, leak-tight seal even under moderate to high-pressure conditions. Each BLRF flange from Harsh Flanges undergoes rigorous inspection for flatness, hardness, and surface finish to comply with global engineering standards.
