To define and secure boilers safely, some professional specialized organizations such as the American Society of Mechanical Engineers (ASME) develop standards and regulation codes.
When water is converted to steam it expands to over 1,000 times its original volume and travels down steam pipes at over 100 kilometres per hour.
Because of this, steam is a great way of moving energy and heat around a site from a central boiler house to where it is needed, but without the right boiler feed water treatment, a steam-raising plant will suffer from scale formation and corrosion.
At worst, it can lead to catastrophic failure and loss of life.
Frequently performed hydraulic services for apartments are repairing a leaky faucet or washing machines, which ceased to spin the laundry.
Similar situation may occur also in the case of hospitals.
Hand auger / hand spinner Hand augers are useful for clearing sink and bathtub drains. They are unsuitable for sending through flush toilets, because the wire might damage the bowl; also, flush toilets have relatively large drain pipes in which the narrow snake can be become tangled. (A 1?4-inch cable, for example, should never be used in a drain with a calibre of more than two inches.) Closet auger / toilet auger The closet auger (named after water closet) feeds a relatively short auger through a hook-shaped length of metal tubing..The hook shape makes it easier to feed the auger into the toilet.
A plastic boot on the end of the auger protects the finish of the visible porcelain.
Since most toilet clogs occur in the trap built into the bowl, the short cable is sufficient to break up or retrieve the greater majority of clogs. Źródło: https://en.wikipedia.org/wiki/Plumber%27s_snake
