Abstract
Method of lining a tubular structure with a plastics liner pipe comprising the steps of:—temporarily reducing an outside diameter of the liner pipe by passing the liner pipe through a roller system;—cooling the liner pipe once its outside diameter has been reduced and applying a thermal restraint;—transporting the liner pipe to an installation site remote from the roller system;—removing said thermal restraint; and—installing the liner pipe in said tubular structure at said installation site.
Claims21
A method of preparing a plastics pipe for transport, comprising:
- temporarily reducing an outside diameter of the pipe by passing the pipe through a roller system;
- cooling the pipe once its outside diameter has been reduced and applying a thermal restraint;
- transporting the pipe to an installation site remote from the roller system;
- removing said thermal restraint;
- and
- installing the pipe at said installation site.
The method of claim 21, wherein the tubular structure is a fluid transport pipeline.
The method of claim 21, wherein the plastics liner pipe is a synthetic polymer pipe.
