Plastic pipe is a tubular section, or hollow cylinder, made of plastic. It is usually, but not necessarily, of circular cross-section, used mainly to convey substances which can flow ? liquids and gases (fluids), slurries, powders and masses of small solids. It can also be used for structural applications; hollow pipes are far stiffer per unit weight than solid members.
Plastic pipework is used for the conveyance of drinking water, waste water, chemicals, heating fluid and cooling fluids, foodstuffs, ultra-pure liquids, slurries, gases, compressed air and vacuum system applications.
Replacing old water valve
When we find that in the house there is a water leak, the cause of which we can not define ourselves, we should immediately call a plumber. It is also important that we immediately shut the main water valve that shut off the water supply to taps and various water bodies existing in the home, and thus we prevent its further flooding. In new homes closing the main valve is not a problem, but in the case of older homes may be harder for us to determine which of the existing valves is the main water valve and an additional difficulty may be the same turn. In such a situation called our plumber will also replace the old water valve installed in our house.
Boiler - what is it?
A boiler is a closed vessel in which water or other fluid is heated. The fluid does not necessarily boil. (In North America the term "furnace" is normally used if the purpose is not actually to boil the fluid.) The heated or vaporized fluid exits the boiler for use in various processes or heating applications,12 including water heating, central heating, boiler-based power generation, cooking, and sanitation.
