Permanent Virtual Circuit (PVC) A permanent virtual circuit (PVC) is a connection that is permanently established between two or more nodes in frame relay and asynchronous transfer mode (ATM) based networks. It enables the creation of a logical connection on top of a physical connection between nodes that communicate frequently or continuously.
PVC (POLYVINYL CHLORIDE) is, by far, the most common. plastic material used for plastic pipe. Its basic properties are. chemical inertness, corrosion and weather resistance, high. strength to weight ratio, electrical and thermal insulators. The service temperature is 140Â°F. PVC has been used. successfully for 40 years in such areas as chemical. processing, industrial plating, chilled water distribution, deionized water, and chemical drainage. Care should be. taken to avoid using with Ketones, Chlorinated.
