In pipe bursting, one of the most integral components that determine the success of the operation are the pipes. Identifying the pipes are essential since the contractors will be able to create plans and used the right methods and materials. Choosing the wrong application will result in a substandard output. This article will tackle both the existing pipes(pipes that need to be replaced) as well as the types of pipes that are installed.
“Fracturable” and “Non-Fracturable” Pipes
It’s emphasised in the pipe bursting method that the existing pipes must be splintered or fractured so that the new pipeline will be inserted. Existing pipes are often identified between “fracturable” and “non-fracturable’’ in order for contractors to determine the suitable method in bursting the pipes. Most pipes can actually be fractured as long as the right method and other factors are considered by the contractor. Therefore, having an experienced, licensed and knowledgeable contractor will also affect the outcome of the operation.
Asbestos Cement Pipes
These cement pipes are actually great for pipe bursting method. However, there are some little changes done to the bursting head so that the bursts will be cleaner and more effective. What most contractors do is add cutter blades to make it easier to cut the pipes. In disposing the AC pipes, the contractor must be able to properly handle the disposal of the pipe according to the local standards of the county.
Most sewer lines that have clay pipes are easy work for bursting since old and damaged and clays can easily be splintered since its already delicate.
A lot of pipes before the 1970’s were made of cast iron pipes and have now been corroded. Property homeowners often lean to pipe relining for their oxidised cast iron pipes, but there are times when replacement is the only option. Again this is another type of pipe that bursting can easily splinter without any issues.
Ductile Iron & Steel Pipes
These pipes may be durable and strong, but pipe bursting can still push through the tough materials. A roller blade may be needed for better bursts.
Plastics pipes such as PVC, HDPE, MDPE, etc.
Plastic pipes are less durable than metal pipes like cast iron, steel, etc. This makes plastic pipes an easy target for bursting. However, there are cases in which both bursting and splitting must be combined to make it easier to completely destroy the existing pipe. Determining the strength and vulnerability of plastic pipes is also important.
New pipes that are installed
In most pipe bursting procedures, the new pipes that are pulled through to take place of the old pipes is HDPE. It’s no wonder that HDPE is preferred by contractors since its flexible and also an adaptable type of pipe. However there are other pipes besides HDPE such as VCP, RCP, and ductile iron. However these pipes are mainly used in static pipe bursting since they can’t be attached to one pipe string before the pipe bursting procedure.
