FLEXIBLE DOUBLE-CONTAINMENT PIPING SYSTEM

摘要

a dual system of underground pipeline transports fluid from the outlet of a pump (37) disposed above an underground storage tank (13), to the inlet of a distributor (35) of liquid surface, e.g. gasoline, is a r in order to prevent the fluid being pumped etenue running of underground pipeline system.in the environment. we can test or replace from the surface of the piping system without digging or penetrate the soil at the place of installation of the tank.a coupling assembly and disassembly for a particularly advantageous system implements a cooperation between the primary inlet (22) and a secondary conduit (19) of the primary conduit so as to define an annular space (27) in which u00e9ventu these leaks are completely contained in said primary conduit.the connection is provided by the coupling of pump and distributor, each internal pipe (23), an adapter (15) of the external conduit, coupling threaded male (20) and compression fittings (17, 18).we can use the system in a station with multiple tanks and multiple distributors, using connectors installed in chambers (12) are used.
