Lap Joint Flanges

Lap Joint flanges are used primarily when quick assembly & dissembly of pipe line section is required under limited working pressure. We provide wide range of Lap Joint flanges that are designed as per the international standards of ASTM, ASME, API, AISI, BS, ANSI, DIN, JIS, MSSP and NACE. We also provide these flanges with mill test certificate as per EN 10204/3.1B. Lap Joint flanges are used on piping fitted with lapped pipe or with lap joint stub ends the combined initial cost of the two items being approximately one-third higher than that of comparable welding neck flanges.
