Inflatable stoppers prevent toxic spills

摘要

A range of large-diameter pipe stoppers designed to prevent accidental pollution of waterways is being introduced by Air Springs Supply. The OFR pollution stoppers from Pronal are installed in water and sewerage pipes. They inflate in emergencies, blocking the pipeline and preventing a toxic spill.rnThey can be inflated using a gas cylinder (typically nitrogen) or by industrial compressed air systems.
