Fracturable and Non-Fracturable Pipes in Pipe Bursting Method
Various methods are under trenchless pipe replacement and one of which is pipe bursting. The pipe bursting method is one of the most unique replacement solutions ever. This method destroys the old pipes and allows the new pipes to be inserted. It’s not your typical pipe repair where pipes have to be dig in order to be removed. This article will focus more on the types of pipes that can be broken by pipe bursting.
These pipes can be easily fractured through a pipe bursting application. Examples of fracturable pipes are asbestos cement, vitrified clay, concrete, and other ceramic materials. We will go in detail with each of these pipe materials.
Old clay pipes can be broken easily but vitrified clay pipes (VCP) are tougher. VCP may require more force since it’s a durable material. Old clay pipes can be busted with not much effort. Clay pipes applied in sewer lines usually have a diameter of 10 cm to 107 cm. These particular pipe materials are suitable for busting.
This pipe material is actually easy to bursts but handling it is troublesome. Asbestos causes health concerns if its particles become airborne. The contractor should know how to handle the asbestos wastes. They can also get help from the authorities for the proper handling of asbestos.
You rarely see any concrete sewer pipes anymore since it’s obsolete. Plain concrete just like the other ceramic materials are breakable. This makes these pipes perfect for bursting. It’s even easier to bursts concrete if it’s in poor condition.
These are actually pipe materials that are still under developmental stage. Despite its early development, some contractors have already used busting techniques on it. The bursting method was complete but there were a lot of adjustments. Bursting tools need to have the strength to puncture that’s suitable to the amount of brick layers.
A non-fracturable pipe doesn’t mean it can’t be bursted. You see, these pipes require special planning and equipment to be broken. Non-fracturable pipes are composed of either plastic or metallic pipe materials.
This pipe material was very popular during the 1970’’s to the 1980’s. In fact, it was used for all construction. Most cast iron pipes today are already old and deteriorated. This makes it easier to bursts. There are special considerations such as the type of cast iron and the age. Specific bursting tools are needed for splitting cast iron pipes.
PVC, HDPE, etc.
PVC and HDPE are plastic pipe materials used for a sewer line. These materials aren’t metal so it’s very brittle. It does require a mix of bursting and splitting methods to be broken. Furthermore, the contractor should identify the strength and quality of the plastic pipe.
These materials are certainly tough. A standard bursting technique won’t be enough to break steel pipes. For these tough pipe materials, a pipe splitting method is used. Roller blades are also added to the bursting tool for easier pipe-splitting.
