Pipe replacement is a secondary option since repairing pipes through trenchless pipe rehabilitation allows for least possible damage to land and properties that are around the work area. Some pipes are beyond repair and a total replacement must be done. Pipe replacement has come a long way since the extremely hassle days of open cut excavation. New methods are more environment and property-friendly. Pipe bursting is a trenchless pipe replacement solution that is becoming a staple among pipe restoration companies. It’s not really a popular method and a lot of people still wonder about this pipe replacement method so here’s a short and concise guide about pipe bursting.

Pipe bursting method in summary

So what exactly is pipe bursting? It’s a replacement method in which the original pipe is purposely broke and split into small pieces while expanding the size of the pipe hole. The new pipe is pulled during the breaking process. There are actually many types of pipe bursting applications but the most commonly used are the pneumatic and static bursting. Pneumatic pipe bursting uses a hammer and expander head to break the old pipes while also enlarging the size of the pipeline. Static pipe bursting doesn’t use any hammer as it only uses either a cable/chain to pull the bursting head and bursts & split the existing pipes. Both pneumatic and static can be used for sewer pipelines but static is the only suitable method for water line pipe replacement. The need for excavation will depend if the crew is able to find suitable entry and exit pits. If they’re unable to find one then they have no other option but to excavate ―— but the excavation is negligible due to the low damage.

What pipes are applicable for pipe bursting?

Virtually all pipes can be busted with the pipe bursting method. Some pipes may be difficult to break but with the right equipment, calculations, and planning ―— most pipes can be broken and split.

Equipment needed for a pipe bursting operation

The primary equipment that is required for pipe bursting are the winch (pulling) machine, expander head, cables, and the hydraulic power generator. Both pneumatic and static used the mentioned tools but pneumatic uses more of a hammer than a bursting head. The winch machine is used to pull in the expander head and the new pipes into position. Most of the equipment is powered by one or more hydraulic generators.

Why pipe bursting is steadily being a preferred option for pipe replacement

Pipe bursting might not be the most popular method for replacing pipes but it’s continually being considered and used by a lot of repair companies. These companies are starting to realise that pipe bursting is actually an efficient method that doesn’t cause heavy disruption to the public as well as the properties that are within reach of the project area. The little need for trenches means heavy excavation is not needed ―— saving a lot of time and money in repair.
