Knowing more about Existing Pipes in Pipe Bursting
When it comes to pipe bursting; the old or pipes that need to be replaced are referred to as the existing pipes. These existing pipes are often designated between “fracturable” or “non-fracturable”. By identifying if the pipes with this specific classification; the pipe contractor will be able to conclude what type of pipe bursting method they will use as well as the suitable set of tools and supplies. Most old type of pipe materials can be easily fractured while others need a bit of adjustments to be perfectly splintered with the right type of pipe bursting method.
- Concrete pipes
-These pipes are pretty common and can be easily fractured through the pipe bursting method. The reason why it can be easily break is because the materials are a bit fragile and can easily crack if applied with the right force. Take note that not all concrete pipes are not easy to break; reinforced or encased pipes are tougher than your usual concrete which is why it needs a specialised type of pipe bursting to be shattered.
- Clay pipes
-Clay pipes were commonly used in the past but was steadily replaced by metallic pipe materials. New and improved clay pipe materials in sewer lines are still used today. Clay pipes that aren’t too thick can be applied with bursting easily since it can fracture with ease.
- Iron and steel pipes
-It may seem difficult to bursts iron and steel pipes due to it being metallic, but despite these materials’ high durability; it can still be broken by pipe bursting. However, a combination of pipe splitting and specialised roller blades must be used for easy cutting of these steel pipes.
- PVC, HDPE, and other types of plastic
-These types of plastic pipes also need a unique approach when it comes to pipe bursting. Plastic pipes require a mix between bursting and splitting applications in order to break without any problems. Also, the bursting tool must be adjusted according to the right size of the plastic pipe to optimise the efficiency of the pressure when bursting. In most pipe bursting applications, its HDPE that is used to replace the existing pipe since its flexible and still a tough pipe material.
- Grooved metal and plastic pipe materials
-These pipes are not easy to fracture due to its structure and materials. If pipe bursting can’t be used for these pipes then the only way to replace these pipe materials is by excavating them. However, new pipe bursting methods can be used to make it more effortless when fracturing these kinds of pipes.
- Brick Pipes
-Brick pipes are rarely used in pipe installations but it’s still need to be considered for a better pipe bursting application. The type of pipe as well as the number of bricklayers needs to be accurately calculated to ensure that the force generated from the bursting or any other equipment used for pipe bursting will be enough to break the bricks. A strong pressure and durable bursting head must be for bricks that have thick layers.
