Safe options for the hazardous leakage containment of underground piping systems

drain conduit, leak detection and they may be retrofitted to existing fittings and valves. Velcro type flexible containment piping system Constructed of durable seamless welding (not sewing) PVC,PU or EVA film. These units are made using transparent film, easy shields that break sprays while containing them (they will not leak out).They are also low price and easy to install.

have easy shields that break sprays without containing them and units that are moderately contained and can be flush as well as drain connected, which are low priced and adaptable to most sites. The weakness lies in cleaning after leaks, and the risk of them leaking on their own. LCH offers custom-made PVC, PU, EVA, FEP, ECTFE, PTFE and grass fibres flexible containment fittings, flanges, valve covers and enclosures. They may also be subject to dimensional constraints as they can be equipped (at an additional cost) with a purge and

Containment pipes were initially developed as a means of containing a fluid that might escape from the primary pipes and for preventing hazardous materials from endangering people or contaminating soil, groundwater or air. Double containment piping systems are very economical and reliable methods for protecting against accidental or intentional leaks of corrosive or hazardous fluids caused by failure of either the primary carrier pipe or its components. The secondary piping is made of plastic and steel. A popular approach to preventing overheating is to totally enclose the gasketed/packed area in a tightly sealed enclosure, which is typically capable of withstanding some internal pressure or vacuum from the outside and therefore assuring better control of external leakage from all parts of the body. Splash guards are constructed by durable sewing of fabrics. These units
