A pipe connection having a protective interior coating, with the integrity thereof being maintained during assembly of the pipe connection by welding. This is achieved by the use of a heat deflecting material that prevents damage to the interior coating from heat generated incident to welding at the weld-affected zone. During assembly of the pipe connection, mating, coacting compressible materials are brought into engagement and thereby compressed to ensure a fluid barrier along the pipe connection after assembly by welding.
