WebUsing expansion joints to deal with thermal movement. If there is no room for an expansion loop, then an expansion joint capable of axial movement should be used. An example of such a product would be expansion bellows. When an expansion joint is being used, consideration must be given to the pressure in the pipe.

WebThermal expansion. When the temperature of aluminium is increased, the metal expands and this is called thermal expansion. One example of thermal extension is that if, for example, the temperature of a piece of aluminium alloy 6063 is -20 ̊C and its length is 2700 mm long, and it is heated to a temperature of 30 ̊C, it will subsequently be ...
