What is the function of the expansion tank cap?- Taizhou Kelong Plastic Mould Co., Ltd.

An expansion tank cap is a small tank used to protect domestic hot water systems from excessive water pressure. The tank is partially filled with air to absorb water pressure and cushion the shock caused by water hammer. The air in the expansion tank also helps to absorb excess water pressure due to thermal expansion. When the water pressure in your domestic hot water system increases, the expansion tank absorbs this excess water pressure and protects the heating system.

Expansion Tank Caps Manufacturers tells you these tanks are made of rubber hoses of a large diameter that are secured to the fittings with clamps. When the pressure builds up, the working fluid will look for a weak point in the line to rupture. The expansion tank cap acts as an overpressure relief valve, preventing this failure. If the valve is broken, the working fluid will rush into the hose, causing a serious problem.

An expansion tank cap is one of the most important parts of your cooling system. It prevents the excessive expansion of plastic engine coolant flange and protects your radiator and other components. It can withstand up to 1.4 bar (20 PSI) of pressure. The expansion tank cap should always be replaced when you have your cooling system serviced.

There are several types of expansion tank caps. Some tanks are vented, while others are non-vented. When you choose an expansion tank, make sure it has a vented cap to prevent overflow. You may also need a catch can or an overflow system. You can also use both types of caps to prevent overflow.
