Double wall pipework for fuel furnaces & emergency generator systems

Computer data centres rely on complex power backup systems involving diesel-generator units. Double wall FOGS pipe systems are being installed between tanks, pump room and the generator.
Several double wall storage tanks, each with a capacity ranging between 100m³ to 120m³, are buried in the vicinity of the building. Liquid tight access chambers are installed on each manway.
A typical data centre has an underground fuel storage capacity ranging from 300m³ to 800m³ to feed the generator units.
The remote fill points, installed in a liquid tight chamber, centralizes the 4” fill lines (one to each of the 4 underground tanks as well as a 2 1/2” lubricant oil delivery line and a 2 1/2” used lubricant oil suction line. All pipe runs are double wall, flexible pipework.
The feed & return line from tank to generator room runs into secondary ducts. Between 1 to 4 primary lines can be inserted into secondary ducts with diameters 3 1/2”, 4 1/2” and 6”. Both primary pipes and secondary ducts are laid in continuous runs, without buried inaccessible joints. At both ends the primary pipes are sealed with the secondary duct by means of flexible boots and special donuts. The boots are equipped with a valve for eventual continuous monitoring of the interstitial space.
