4.Oil Jetties.
5.Loading and unloading gantries.
6.Off- Shores Platforms.
7.Warehouses.
8.Foam application through spray nozzle and foam sprinkler.
Operation
1.During operation, water is charged between the foam vessel and the foam bladder, thereby causing the pressurization of foam concentrate stored inside the foam bladder to a pressure, as that of fire water supply.
2.The Foam Concentrate is injected in the fire- water stream due to pressure drop at the foam proportioner. Foam proportioner provides accurate and automatic proportioning of foam concentrate within its flow range with very low proportioning losses.
Specification
Foam vessel is designed and fabricated to ASME Sec. VIII Div. for a maximum working pressure of12.06 Bar and Hydro tested to a pressure of 18.09 Bar. Internal surface is coated with coal tar epoxy and external surface with fire –res epoxy paint. Lifting lugs are welded to the vessel. Vertical Vessel is provided with legs supports and horizontal vessel with saddle supports. Anchoring holes are drilled in the base plate of supports. Anchor bolts are also supplied with the unit. Foam Bladder is made of Nylon reinforced nitrile rubber, which is fixed inside the vessel.
