Definition of pipe

A pipe is a tubular section or hollow cylinder, 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 pipe is far stiffer per unit weight than solid members. In common usage the words pipe and tube are usually interchangeable, but in industry and engineering, the terms are uniquely defined. Depending on the applicable standard to which it is manufactured, pipe is generally specified by a nominal diameter with a constant outside diameter (OD) and a schedule that defines the thickness. Tube is most often specified by the OD and wall thickness, but may be specified by any two of OD, inside diameter (ID), and wall thickness.

Pipe is generally manufactured to one of several international and national industrial standards.1 While similar standards exist for specific industry application tubing, tube is often made to custom sizes and a broader range of diameters and tolerances.

Many industrial and government standards exist for the production of pipe and tubing.

The term "tube" is also commonly applied to non-cylindrical sections, i.e., square or rectangular tubing.

In general, "pipe" is the more common term in most of the world, whereas "tube" is more widely used in the United States. Both "pipe" and "tube" imply a level of rigidity and permanence, whereas a hose (or hosepipe) is usually portable and flexible.

Pipe assemblies are almost always constructed with the use of fittings such as elbows, tees, and so on, while tube may be formed or bent into custom configurations. For materials that are inflexible, cannot be formed, or where construction is governed by codes or standards, tube assemblies are also constructed with the use of tube fittings.Źródło: https://en.wikipedia.org/wiki/Pipe_(fluid_conveyance)

Ambulance water and sewer

plumber Hounslow The blocks may be different failures sewage.
Within a week, they are repaired by a team of plumbers employed in cooperatives.
In contrast, during the holiday season, or in the case of sudden death during the night, residents will be able to call the emergency water and sanitation and ask to come to the block where the accident occurred.
In some situations it may become necessary to purify the basement flooded by the sewage system before the tenants will be able again to enter it.

Sewer block can be cleaned using methods commonly used to clean drains, such as.

Pressure method.

Hot water in central heating

Early hot water systems were used in Russia for central heating of the Summer Palace (1710?1714) of Peter the Great in Saint Petersburg.
Slightly later, in 1716, came the first use of water in Sweden to distribute heating in buildings.
M?rten Triewald, a Swedish engineer, used this method for a greenhouse at Newcastle upon Tyne.
Jean Simon Bonnemain (1743?1830), a French architect, introduced the technique to industry on a cooperative, at Château du P?cq, near Paris. However, these scattered attempts were isolated and mainly confined in their application to greenhouses.
Tredgold originally dismissed its use as impractical, but changed his mind in 1836, when the technology went into a phase of rapid development. Early systems had used low pressure water systems, which required very large pipes.
One of the first modern hot water central heating systems to remedy this deficiency were installed by Angier March Perkins in London in the 1830s.
At that time central heating was coming into fashion in Britain, with steam or hot air systems generally being used. Perkins' 1832 apparatus distributed water at 200 degrees Celsius (392 °F) through small diameter pipes at high pressure. A crucial invention to make the system viable was the thread screwed joint, that allowed the joint between the pipes to bear a similar pressure to the pipe itself. He also separated the boiler from the heat source to reduce the risk of explosion.
The first unit was installed in the home of Governor of the Bank of England John Horsley Palmer so that he could grow grapes in England's cold climate. Źródło: https://en.wikipedia.org/wiki/Central_heating#Hot_water.
