PROCESSO DE OBTER UM CONJUNTO INCLUINDO UM TUBO DE METAL E UM CORPO CIRCUNDANTE

摘要

A method of making an assembly including a metal tube and a surrounding flange member comprises providing an abutment shoulder at the open end of the tube, passing a spacer sleeve along the tube into engagement with the shoulder, placing the flange member in engagement with a flange of the sleeve and welding one end of the spacer sleeve to the shoulder and the other end thereof to the flange. It is alternatively possible for the flange and sleeve to be integrally formed, in which case only welding to the shoulder is required.
