Cold feed is cold water that supplies boiler water for heating system. Expansion tank relieves excess pressure buildup in heating system.
The Cold feed should enter the supply line rather then the return as not to thermo shock a boiler and the expansion tank is to protect the system from excessive pressureAs water is heated it expands causing higher pressures the tank acts an asorber for this expansion
Oh, what a lovely question! In a direct system of cold water supply, the purpose of the cold feed pipe is to bring fresh, cold water into your home's plumbing system. This pipe ensures that you have a constant supply of cold water for drinking, cooking, and other daily activities. Just like adding a touch of blue to your painting to create depth and balance, the cold feed pipe plays a crucial role in maintaining a harmonious flow of water throughout your home.

If you are referring to a regular building, the cold water feed pipe goes directly to all cold faucets, toilets and hot water tank. The purpose seems obvious.
Which pipe connects to where on the Wessex flange i.e. feed to pump connection and feed to expansion tank and hot water taps?
Probably due to an airlock in the cold water system (feed pipe).
To save the piping from breaking during thermal expansion (day/night, summer/winter). They provide the needed space to expand withought breaking the system.
The alternator oil pipe on combo van leaking does feed the vacuum and the return pipe.
Pipe Expansion Joint
pipe
Expansion joints are used on long runs (over 100 feet) of pipe or ducts where the expansion of steel will create stress on the pipe or its supports. for every 1 degree change in metal temperature the pipe will expand 6 millionths of a foot per foot of length. on a steam pipe 400 foot long carrying 750 degree steam this expansion would amount to a change in length of the pipe of 1.632 feet. this could tear down the supporting structure if this expansion weren't relieved by an expansion joint every 100 feet. expansion joints could be flexible corrugated pipe, reinforced rubber sheet, sliding pipe joints, or expansion loops, among other things.
