Introduction to Steam Distribution -

When the boiler main isolating valve (commonly called the crown valve) is opened, steam immediately passes from the boiler into and along the steam mains to the points at lower pressure. The pipework is initially cooler than the steam, so heat is transferred from the steam to the pipe.
