Tuboscope

A replacement pipe section for a defective pipeline that includes two tubular members telescopically assembled so that the assembly has an adjustable overall length. The replacement pipe section includes a collar that can be disposed around and attached to both tubular members, thereby fixing the overall length of the assembly. The ends of the replacement section can then be attached to the fixed open ends of the pipeline to create a fluid-tight assembly. The replacement pipe section is particularly effective for permanently replacing a defective section of an internally coated pipeline.

Replacement pipe section for a defective pipeline

A coupled pipe assembly having a pair of opposed, axially positioned pipes each having opposed beveled ends and interior corrosion-resistant linings. A sleeve having heat-insulating material is inserted axially within the pipes with the heat-insulating material being positioned adjacent the opposed pipe ends to protect the corrosion-resistant linings from heat produced during the welding of the pipe ends. The sleeve has a uniform, continuous diameter along the entire length thereof.
