Correct Fill Line for Chemical Tanks
Correct Fill Line for Chemical Tanks, when filling chemical and water storage tanks, the correct fill line is important for the safety of persons and equipment and prevent loss of product. The fill line is a pipe system attached to the tank and generally made from PVC, CPVC or PE pipe to ensure compatibility with the chemicals being stored in the tank.
These fill pipes are available as bsp sockets, PN16 flanges with an optional chemical-grade valve with camlock or tanker connection for quick connecting and disconnecting after filling.
Tanker fill lines are available as standard up and over internal and external pipework, anti-foam fill lines for foaming chemicals and pumped suction lines which run from low level in the tank to low level outside the tank.
External Chemical Tank Fill Lines
Exterior chemical tanks fill lines are mounted on to the external wall of the tank, mounted to the outside of the chemical tank, run up the side and fill from the top of the tank. These fill pipes either terminate in a BSp socket or a PN16 flange which allows fittings and valves to be fitted to connect to a tanker.

Anti-Foaming Fill Pipes
Anti-foaming fill pipes are supported inside the tank and run to the floor to prevent foaming for chemical such as firefighting foam concentrate. These fill pipes run up the outside wall of the tank and through the roof of the tank.
Some installations require the pipework to go from low level in the tank to the tank roof to connection to pipework in the factory or in the plant. These suction lines are internally mounted in the tank and terminate in either a BSP socket or a PN16 flange on the top of the tank.
This combination pipework gives a fill on the outside of the tank for tanker connections but runs to the low level inside the tank reducing foaming during filing.
Overflow pipework is generally required to prevent overfilling the chemical, wastewater, or process tank. These can be a high-level overflow or pipped to low level terminating in a flange for plant room installations. In a bunded tank a bund alarm is recommended letting plant maintenance personnel know the tank has overfilled.
Suitable Venting of For the Tank
Correct venting of the tank is required as tanker fill lines generally pump into the tank at a greater rate than a standard lid vent tank allow air within the tank to escape. Some chemicals such as HCL will need to be vented to a scrubber.
The Correct Fill Line for Chemical Tanks for your storage tanks depends on the chemical you are storing, how its delivered, and the requirements for your tank and pipework within the factory. These pipes will need to be mounted to the tank securely and- for more details on the correct fill lines for your next chemical storage tank, please get in touch with us today.
