What is double walled piping?

Double walled piping is a type of pipe consisting of two separate walls or layers. The space between the two walls is typically filled with an insulating material. The purpose of the double wall is to provide an extra layer of protection against leaks or spills. If a leak occurs in the inner wall, the outer wall provides a secondary barrier to prevent the material from escaping into the environment.

Double walled piping is commonly used in industrial applications where the material being transported is hazardous or environmentally sensitive. It is also used in underground piping systems where leaks can be difficult to detect and repair.

The materials used to manufacture double walled piping vary depending on the application and the material being transported. Some common materials include stainless steel, fiberglass reinforced plastic (FRP), and high-density polyethylene (HDPE).

Regular inspections and maintenance are essential for ensuring the integrity of double walled piping systems. Leaks or damage to the inner wall should be detected and repaired promptly to prevent environmental damage or health hazards.
