Abstract: A continuous process for lining pipes with thermosettable polymer made from prepolymer and curing agent, comprising the steps of: heating and degassing the prepolymer and storing it in a first storage tank; providing the curing agent in liquid form at a curing temperature in a second storage tank; recycling the prepolymer and the curing agent between the storage tanks and a mixing head which is selectively operable to mix and discharge the reagents; arranging each pipe with its longitudinal axis inclined at an angle to the horizontal; introducing a selected amount of the polymer mixture into the pipe at a predetermined rate so that the liquid material flows down along the pipe; and shifting the pipe to a horizontal position and spinning the pipe about its axis to distribute the material, spinning continuing until the material has set.

Abstract: A method of lining a pipe with settable material including the steps of arranging the pipe with its longitudinal axis inclined at an angle to the horizontal, introducing a selected amount of liquid material into the pipe at a predetermined rate so that the liquid material flows down along the pipe, shifting the pipe to a horizontal position and spinning the pipe about its axis to distribute the material, spinning continuing until the material has set. The method is particularly applicable for lining pipes with polyurethane. For pipes with end flanges end faces of the lining material can be formed integral with the lining.

Abstract: There is described a method of joining a first metallic structural member, which comprises a metallic member having a coating of a heat-degradable material on one surface thereof, to a second metallic structural member which comprises a metallic member, along abutting edges by forming a welded joint between the abutting metal edges of the metallic members in which method the metallic member and the coating of the first structural member are separated along that edge of the first structural member which is to be welded to the second structural member by a heat shield which substantially prevents heat being transferred from the welded joint, during the formation thereof, to the coating.

Abstract: A method of lining a pipe with thermosetting synthetic plastics material including the steps of arranging the pipe with its longitudinal axis inclined at an acute angle to the horizontal, introducing liquid lining material into the pipe at a predetermined rate for a predetermined time, shifting the pipe to a horizontal position shortly before or at the completion of introduction of the liquid material, spinning the pipe about its axis and blowing hot air axially through the pipe after spinning has started but before the lining material has set thereby to remove entrained air bubbles. The method is particularly applicable for lining pipes with polyurethane, especially pipes with end flanges and covers to form an end face of the lining material.
