Double Wall Containment Piping Systems
Asahi/America has been providing double containment piping systems to meet Environmental Protection Agency (EPA) standards for over 25 years. As the innovator and patent holder of many double containment specialty devices, Asahi/America is best equipped to help engineers and designers fabricate and install double containment piping systems.
Our systems are engineered to protect our eco-system from the dangers of exposed aggressive chemicals. Additionally, the EPA has directed the underground transport of hazardous materials be protected from release into the environment in its Standard 40 CFR, Part 280 & 281. In order to be in compliance, systems must:
Double containment should be specified for more applications than regulated by the EPA. Hazardous chemicals should be protected from escape in areas where there are chemicals transported above work stations, or any other potential safety hazards due to exposure to the media.
Asahi/America has been the industry leader in engineered thermoplastic double contained piping systems for decades. Our systems have been successfully installed with confidence across a broad range of industries. Ranging in sizes from 1x2 to 16x20 and above, choosing Asahi/America provides maximum flexibility in system engineering and design. For the varying requirements of double containment, Asahi/America provides a variety of piping system options.
