ASTM A105 carbon steel lap joint flanges are designed for applications where easy disassembly and reassembly of the piping system are required. Unlike other flange types, lap joint flanges consist of a flat flange and a loose backing flange that allows for the pipe to be easily removed or replaced without removing the entire flange assembly. Made from ASTM A105 carbon steel, these flanges are suitable for high-pressure and high-temperature environments, offering strength and durability. They are commonly used in industries such as oil and gas, petrochemical, and power generation. The lap joint design simplifies alignment and allows for the flange to be positioned at various angles to facilitate maintenance and adjustments.
