Fuel Storage

Petroleum storage tanks and cryogenic storage facilities (liquid natural gas, LPG, ethylene, ammonia, etc.) require sensitive monitoring in order to allow for ample warning of elevated temperatures prior to combustion. By providing advanced notice of rising temperatures, appropriate steps can be taken to prevent disaster. Senkox HSD™ Linear Hot Spot Detectors are an ideal solution to fill this role.

The flexible Senkox HSD Linear Heat Sensor cables can be directly mounted around the tank. The system provides real-time temperature monitoring and also detects the precise location of hot spots. As a result, safety personnel have real-time data of the thermal conditions of the storage tanks. This feature provides advanced warning and extra time for working personnel to counteract the repercussions of overheating.

Floating roof tanks are vulnerable to elevated temperatures due to the highly abrasive environment and presence of flammable gases. HSD Linear Hot Spot Detectors are most likely to occur near the secondary seal of a floating roof tank, as these are the areas that suffer most from high abrasion and the presence of flammable gases. The HSD  sensors are installed along the secondary seal of the floating roof tank to provide real-time data regarding temperature changes.

Spherical storage tanks are commonly located in areas of high fire risk. HSD sensors are installed on the surface of the sphere, allowing continuous temperature monitoring. Detection of any hot spots will trigger location specific sprinkler systems.
