Pipe cracking is a specialized method of rehabilitating underground pipelines that involves inserting a new pipe into an existing damaged or deteriorated pipe, using hydraulic pressure to crack and expand the old pipe while simultaneously inserting the new pipe. Here’s a general overview of the process:
INSPECTION:
The first step in pipe cracking is to inspect the existing pipeline to assess the condition and identify any areas of damage or deterioration.
PREPARATION:
Once the damaged sections of the pipeline have been identified, the pipeline is cleaned and prepared for pipe cracking. This may involve removing any debris or build-up from the inside of the pipe and ensuring that the surrounding area is clear of any obstacles.
PIPE CRACKING:
Pipe cracking involves inserting a new pipe into the existing damaged pipe and using hydraulic pressure to crack and expand the old pipe while simultaneously inserting the new pipe. This is typically done through a small access point, minimizing disruption to the surrounding area.
JOINT SEALING:
Once the new pipe has been inserted and expanded, the joints between the old and new pipes are sealed to ensure that the pipeline is watertight and structurally sound.
INSPECTION AND TESTING:
After the pipe cracking process is complete, the pipeline is inspected to ensure that the repair has been successful and the pipeline is functioning properly. This may involve our team using cameras or sensors to inspect the repaired area and conducting pressure tests to ensure that the pipeline is structurally sound.
Pipe cracking can be an effective method of rehabilitating underground pipelines, as it minimizes the need for excavation and disruption to the surrounding area. However, it is important to note that pipe cracking may not be appropriate for all types of damage or deterioration, and more extensive repairs or replacement may be necessary in some cases.
