Which repair method involves enclosing the original piping system?

The correct approach involves encapsulation, which is a method designed specifically for enclosing the existing piping system. This process typically entails wrapping or covering the pipe with a protective layer or material that isolates it from external elements, thereby preventing further deterioration or leaks. Encapsulation is often utilized to manage damaged pipes without the need for complete replacement.

Using this method can enhance the pipe's lifespan by providing additional structural support and protection. It can be particularly useful in situations where the original pipe is still structurally sound but needs extra safeguarding against environmental factors or internal corrosion.

Other methods, such as welding, involve joining or repairing sections of pipe rather than enclosing the entire system. Inspection refers to assessing the condition of the piping rather than performing repairs. Patch repair is focused on addressing specific defects or leaks in a localized area, rather than encompassing the entire piping system.
