Mahesh Industries is a trusted manufacturer, supplier, and exporter of high-quality Raised Face (RF) Flanges, known for their strength, durability, and excellent sealing performance. Raised Face flanges are designed with a small raised area around the bore, which concentrates pressure on the gasket surface for a tighter, leak-proof seal. Ideal for high-pressure and high-temperature applications, our RF flanges are manufactured using premium materials such as stainless steel, carbon steel, and alloy steel. Compliant with international standards, Mahesh Industries' Raised Face Flanges are widely used in petrochemical, oil & gas, and industrial piping systems across the globe. ASME B16.5 Raised Face Flanges are commonly available in slip-on and weld neck types, offering reliable performance in various pressure applications. These flanges feature a small raised portion around the bore, which enhances gasket compression and provides a leak-proof seal. The height of the raised face depends on the flange's pressure-temperature rating, known as its class. For 150# and 300# Raised Face Flanges, the height is typically 1/16”, while for classes above 300#, it increases to 1/4”. A ring-type gasket fitting within the bore circle is used with these flanges, ensuring secure and efficient sealing under demanding conditions.
