Chlorine Service

While Resistoflex Plastic-Lined Piping Products can be used in dry chlorine service, The Chlorine Institute states that it may be more economical to use carbon steel - as long as the system will be operated in the temperature range between -20°F and 300°F (-30°C to 150°C), and if no moisture will be introduced.

Contact The Chlorine Institute at 1-202-775-2790 for information regarding the use of metallic piping systems for dry chlorine service.

There are many locations, such as injection points or the downstream side of barometric loops, where moisture may make PTFE or PVDF-lined pipe a more attractive alternative than carbon steel. In these locations, you should design for wet chlorine rather than dry chlorine. If PTFE-lined pipe is used, the temperature limit is 300°F (150°C). At temperatures above this, a reaction may result between the carbon steel outer shell and chlorine permeating through the PTFE liner, possibly causing a fire. If plastic-lined pipe is being considered for a pressurized chlorine liquid application for maximum working pressures, contact Resistoflex Technical Service at 989-671-3100.
