Problem Statement

  • Pipelines are used in transportation of fluids like water, oil and gas, slurry, brine etc over long distances; damages to the pipelines can be due to coating, erosion, corrosion or mechanical damage etc
  • In traditional repair techniques, repairing of pipelines requires the flow of an internal fluid to be temporarily stopped to avoid a possibility of ignition or explosion of the internal fluid where temporary stopping of the internal fluid, result in huge losses

Technology

  • The apparatus for repairing pipes using composite wrap includes: 

  • Rotating Rings move within the guide grooves of the fixed rings
  • Roller Brush cleans the defective surface of the pipe repair the defective surface of the pipe by applying a layer of repair chemical to fill the damaged area
  • The said pressing roller exerts a rolling pressure on the sheathing material to provide a homogeneous adherence of the sheathing material to the defective surface of the pipe
  • Also, a motor with a pinion fixed with a fixed ring and a rotary gear assembly for rotating the rotating rings  wraps sheathing material over the defective area on the pipe
  • Repair chemical includes glass fiber, a thermoset resin, and an epoxy.
  • The flowchart below represents the method of  repairing the pipe using composite wrap:           

Key Features/Value Proposition

Technical Perspective:

  • The present invention provides an apparatus for repairing pipes using a composite wrap
  • Capable of repairing corroded straight pipes which has corrosion in the outer surface , where  repair can be carried out with out stopping the flow of gas or oil in the pipeline 
  • The pair of repair chemical dispensing rollers helps to  to wet the sheathing material wraps the defective surface of the pipe

Industrial Perspective:

  • Provides the wrap over the outer surface of the affected pipe with minimum workforce
  • Prevents leakage and capable of restoring maximum allowable transporting capacity of the pipeline
