Understanding Pipe Rerounding

First of all, let’s understand what pipe rerounding is. Pipes, whether made of metal or plastic, are typically designed to be cylindrical, with a round cross-section.

However, over time, various factors can cause pipes to become distorted. This results in an oval or irregular shape. This distortion is referred to as pipe ovality. Pipe rerounding can occur due to a range of reasons, including:

  • Ground Settlement: The shifting of the earth’s surface can cause pipes to settle unevenly, leading to ovality.
  • Corrosion: Rust and corrosion can eat away at the walls of pipes, weakening their structural integrity and causing them to deform.
  • Thermal Expansion and Contraction: Extreme temperature fluctuations can cause pipes to expand and contract. This can lead to what is called pipe ovality.
  • Installation Issues: Improper installation techniques can result in pipes being squeezed or bent, causing them to become oval.

Consequences of Pipe Rerounding

Pipeline ovality might seem like a minor issue, but it can have far-reaching consequences for your drainage system. Some of the potential problems include:

  • Reduced Flow: Oval pipes can impede the flow of water, leading to reduced water pressure and slower drainage.
  • Increased Risk of Leaks: Oval pipes are more prone to leakage and cracks, which can result in water damage to your property.
  • Costly Repairs: Addressing issues caused by pipe ovality can be expensive, especially if they result in major leaks or the need for pipe replacement.

Pipe Rerounding

Fortunately, there’s a solution to combat pipe ovality – Pipe Rerounding. This specialised drainage service involves restoring pipes to their original, round shape. 

Here’s how it works:

  • Inspection: A trained operative will inspect your drainage system to identify areas where pipeline ovality is present.
  • Reshaping Process: Various methods can be employed to reshape the pipes. One common technique involves using Pneumatic vibration that vibrates bedding around the pipe and then gently expands the pipe to its original round shape.
  • Quality Assurance: After reshaping, the plumber will ensure that the pipes are now perfectly cylindrical and free from defects.

Deflection testing proves to be an invaluable method for verifying the effectiveness of embedment placement and compaction in non-pressure flexible pipelines. This meticulous process entails the use of a certified proving tool systematically drawn through each segment of the sewer pipeline. 

Its primary purpose is to discern any instances where the pipe may have undergone compression, deformation, or obstruction, whether caused by a compaction gravel accumulation during the installation process or over compaction.

Benefits of Pipe Rerounding

 Pipe Ovality offers numerous benefits, such as:

  • Leak Prevention: By eliminating the ovality, the risk of leaks and cracks in your pipes is significantly reduced, saving you from potential water damage.
  • Extended Lifespan: Reshaping pipes can extend their lifespan, reducing the need for costly replacements.
  • Cost Savings: Investing in pipeline ovality reshaping is more cost-effective than dealing with major plumbing repairs or replacements.
  • Eco-Friendly: Improved water flow means less water wastage, making your plumbing system more environmentally friendly.
