A method comprises diffusion metal coating of pipes carried out in a vacuum chamber which contains metal evaporators. Prior to coating process a metal is fed into the interior of each pipe with the melting temperature thereof being substantially below that of the pipe metal. The metal coating of pipes is effected at a temperature above the melting temperature of the metal disposed within the pipes which are continuously rotating about their axes while axially advancing through the metal evaporator.

Method for applying protective coating to metal pipes

Substrate supply and windup rolls are arranged in a housing arranged at each end of a vacuum coating chamber. Gate means provide for optionally sealing of one housing for loading and unloading purposes while simultaneously coating a continuous strip related to the supply and windup rolls of the second housing. Carriage means carry tension rolls at the extreme ends thereof and reciprocate across the coating chamber in operative association with said housings at the extremes of the reciprocating movement whereby to effect the coating and loading or unloading operations.
