Paper manufacturers rely on piping systems for the safe conveyance of Sodium Hypochlorite (NaOCI), commonly known as bleach, to whiten raw paper. One such manufacturer was experiencing leaks from corroded welds in their stainless steel Sch 40 316L piping system.
In order to provide a safer work environment and protect sensitive equipment, management sought a better solution for handling NaOCI in their manufacturing processes. Paper manufacturing is recognized as an extremely harsh application for any piping system. With that in mind, the owner felt that if any new system could last more than six years, the installation would be considered a success.
After investigating several types of piping systems, the Double-See™ Double Containment corrosive waste piping system in PVC/CPVC from GF Piping Systems was chosen as the solution. The pressure rated system offers ASME B31.3 installation compliance as well as a simultaneous joining design.
“Double-See was the only plastic piping system that could meet the requirements and handle the extremely harsh environment,” says Terence Zhao, Product Manager of Engineered Piping Systems for GF Piping Systems. “Easy installation combined with the use of GF Harvel Enviro King clear as the containment pipe to allow for visual leak detection and its UV resistant characteristics, made the system more attractive than other systems on the market.”
