Piping system for hazardous fluids

摘要

The leakage of hazardous fluid from the pipe sections or from between the pipe sections is monitored by butting concentric pipe section sets which define a cylindrical leakage collection and monitoring means to a special fitting which has a pair of seals and a passage to the collection means therebetween, so that leakage at the pipe intersections is collected and passed to the normal pipe-defined leakage collection and detection apparatus used to monitor pipe section leakage.
