Low, Medium and High Pressure Boiler Tube

Most plants have medium pressure boilers producing steam for space heating: many need steam for other purposes as well. Boiler water requirements for boilers have changed radically over recent years. The old 'Lancashire' and 'Economic' boilers had large heating surfaces and low heat transfer rates: scale deposits would do no more harm
