Looking for Raised Face Lap Joint Flanges, LJRF Flange, LJFF Flange, EN 1092-2 PN16 Lap Joint Flange Dimensions, ASME B16.47 / ANSI B16.5 LJ Flange, MSS SP-44 Lap Joint Flange, DIN 2642 Lap Joint Flange.
Bhavani Industries is a leading manufacturer and supplier of high-quality Lap Joint Flanges (LJ Flanges), delivering reliable solutions for piping systems that require easy disassembly, inspection, or frequent alignment. LJ Flanges are designed to be used with a stub end, which allows the flange to rotate freely around the pipe for effortless bolt alignment. This makes them ideal for low-pressure, non-critical applications across various industries.
LJ Flanges manufactured by Bhavani Industries conform to global standards such as ASME B16.5, ANSI, and MSS-SP-44, supporting pressure classes ranging from 150 to 900. These flanges are typically Flat Face (FF) and are offered in a wide selection of materials including carbon steel (ASTM A105), stainless steel (ASTM A182 F304/F316), and low-temperature carbon steel (ASTM A350 LF2). In this design, the stub end is welded to the pipe while the flange remains loose, enabling easy maintenance, rotation, and bolt-hole alignment in tight spaces.
Available in sizes from ½ inch to 24 inches, Lap Joint Flanges are commonly used in water treatment facilities, chemical processing plants, food and beverage industries, shipbuilding, and pharmaceutical pipelines. Their design allows for reduced material costs, especially in systems using exotic alloys, as only the stub end needs to match the pipe material. With features like easy installation, reusability, and alignment flexibility, LJ Flanges from Bhavani Industries are an excellent choice for efficient, cost-effective piping solutions.
