Propane tanks are an approved tank to hold propane in its gas form and liquid form. There are many sizes and types of propane tanks and they all serve a specific need.
Stationary tanks are usually used for businesses, farms, and homes. These tanks generally come in sizes to hold 120, 250, 325, 500, and 1000 gallons. These tanks can either be installed above ground or below ground. These tanks are serviced and filled by your propane provider and can be filled to the maximum allotment of 80%.
These tanks have special valves required for safety when dealing with propane. These valves include:
- Fill Valve- Used to attach a delivery hose to the tank for filling.
- Vapor Return Valve- Used to maintain pressure when filling.
- Relief Valve- Used to bleed off excess pressure in emergency situations.
- Liquid Withdrawal Valve- Used to govern amount of LP gas withdrawn from the tank.
Along with these valves, the tank must also have two types of working gauges.
These gauges include:
- Float Gauge- Used to determine amount of propane in the tank.
- Fixed Level Gauge- Used to warn when the level is about to reach the maximum 80% fill.
