Water supply polyethylene pipes - the future of water supply systems

Ease of transportation, speed of installation, environmental safety ... It is thanks to these properties that water - supply polyethylene pipes go to the leading positions in the construction of piping systems. They are also practically non-corrosive and capable of withstanding a hydraulic shock.

There is another parameter, which is very important for both customers and installers. If we compare how much a polyethylene tap pipe costs, its price, unlike metal, is much lower.

Polyethylene pipes made of polyethylene of different types - high, medium and low pressure - are manufactured and, depending on the material, the field of application of the product is determined.

The highest density, surprisingly, in polyethylene produced by low pressure. The polyethylene pipes made of it are used in pressure pipelines. Pumping on them can not only liquid, but gas. Also, such pipes are used where the liquid is moved by gravity. For example, in sewage systems.

The field of application of polyethylene pipes is extensive. Although they are involved mainly in water supply systems - external and internal, but are installed in both drilling and electrical work. Polyethylene has dielectric properties, it does not electrify. Therefore PE pipes are used as cases for high voltage cables .

There is only one "but". High temperatures water pipes can not tolerate polyethylene pipes, therefore for hot water supply are unsuitable, as well as in fire extinguishing systems.

Determine which pipe is required in one or another field of application, it is possible by marking. For example: polyethylene water pipe PE-32 SDR 21 means that the polyethylene pipe has an outer diameter of 32 mm, a wall thickness of 2 mm. Such pipes are used in the sphere of household and drinking purposes.

The assembly of pipes depends on the diameter and operating conditions of the pipeline. Pipes are connected in a single system with the help of fittings - universal fixators. With their help also in the pipelines are installed devices with shut-off and control valves in the case of external water supply, and sanitary - in the case of internal.

Connections PE pipes are disconnected and non-removable. Untypical connections include welding and gluing, to detachable joints - flanged (using nuts) and bell.

Mounted water-supply polyethylene pipes as a detachable method, and non-removable.

Welding is used mainly in outdoor plumbing systems, in large diameter pipes. Welded joints are convenient in case of underground and above-ground pipeline laying and allow maintaining the flexibility and strength of the system along the entire length.

Pipelines of small diameters, especially used in internal systems, are glued using a special glue or installed with the help of detachable connections. The latter provides convenience in maintenance of water pipes and during repair work.

Pipe made of polyethylene - the future of the pipeline industry. The scientist has only to invent a substance that will withstand the heat.
