Pipe Bursting

What is Pipe Bursting?

Pipe bursting is a trenchless method of replacing old, damaged, worn out, buried pipelines (such as sewer, water, or natural gas pipes) without actually digging a trench. Bursting and splitting by using the existing alignment to replace a pipe avoids the need to secure additional right-of-way to install the replacement pipe. Bursting and splitting can be used to upsize the pipeline increasing its flow capacity.

What is the process of execution?

  1. Advance a conical-shaped bursting head that has a diameter a few millimeters larger than the new replacement pipe, through the existing pipe.
  2. The radial expansion caused by the geometry of the bursting head surmounts the host pipe’s tensile and shear strength capacities, resulting in the fragmentation or splitting of the pipe.
  3. As the bursting head is pulled through the host pipe, the fragments are pushed into the resulting annulus, creating a cavity for the product pipe.
  4. The product pipe immediately follows the bursting head as it is simultaneously pulled or pushed into the newly formed cavity.

How is Pipe Bursting used?

  • Oil and Gas
  • Drainage and Sewer systems
  • Water Resources

Some projects where we have executed Pipe Bursting

  • Executed pipe bursting upto 450 mm dia, for sewer systems, for Delhi Jal Board.
  • Executed pipe bursting, for sewer systems, for Municipal Corporation of Greater Mumbai (MCGM).
