Learn About Dual Containment Pipes
Dual Containment Pipes made of HDPE (High-Density Polyethylene) are a type of piping system that consists of two separate pipes—one inside the other. The inner pipe carries the primary fluid or substance being transported, while the outer pipe acts as a secondary containment layer. This design creates a double-walled structure that provides an additional layer of protection against leaks, spills, or potential environmental contamination.

Dual containment HDPE piping is used to enhance safety and prevent potential hazards in situations where the transported substances are hazardous, corrosive, or environmentally sensitive. By having a secondary containment layer, any leaks or breaches in the inner pipe are contained within the outer pipe, reducing the risk of harm to personnel, the environment, and infrastructure. This makes dual containment HDPE pipes ideal for industries such as chemical processing, wastewater treatment, and other applications where containment and environmental protection are critical.
In dual containment HDPE piping systems, the inner pipe is typically secured within the outer pipe through various means such as brackets, spacers, or other support mechanisms. Allowing the inner pipe to be free-floating inside the outer pipe is generally not recommended, as it could compromise the effectiveness of the containment system and create potential points of stress or contact that may lead to wear or damage.

Fusing pipes in a dual containment system can be a complex process due to the presence of two separate pipes. The inner and outer pipes can be fused separately before being assembled into the dual containment system. This become increasingly difficult the longer your system becomes. An alternate to this is a special techniques developed by WGS Plastic Services though years of experience which has been developed to fuse both pipes in conjunction with each other. Both pipe is typically fused using standard butt fusion techniques, which involve heating the ends of the pipes and then pressing them together, with specific pressure to create a seamless joint.
