Polyethylene pipes are universal thanks to the excellent characteristics of the material. More and more applications in everyday life finds pipe HDPE. Installation can be done with your hands, if you do everything by the rules. This does not require a special qualification.
A Great demand for HDPE pipes caused by high quality material
In the house or in the country of HDPE pipe are made:
For the drinking water to acquire pipes with a diameter of not more than 60 mm with a wall thickness of 4 mm. They should be designed for a working pressure of fluid in the system is not lower than 1MPa. Advantage is no corrosion and the metallic taste of the water. If you want to arrange a hot water supply, it is necessary to know that at a temperature of 800With the polyethylene is softened, and at its further increase begins to melt. In this regard, you should choose the brand not lower than PE80. Hot water pipes can also be fitted with a PE-RT or PN20, they can withstand heating up to 1100C. For conditions that is enough.
We Must distinguish between pipes for water supply and pressure. For normal operating conditions of the water are the Bay of 25 m length with a wall thickness of at least 2 mm. If the main artery runs under good pressure and has a diameter more than 25 mm, the drainage is taken inch pipe. In any case, a recusation shall be smaller cross-section than the General water supply.

Before installation, select the connection method, which can be as follows:
The connection Method is selected depending on the following factors:
Most durable work welded and flanged connections. Threaded coupling with seal resistant to stress. Installation of HDPE pipes for water supply with compression fittings is usually done on private land for watering systems of plants.
The weakest connection socket. They are used only in non-pressure pipelines except in those cases where the connection is welded.
For the HDPE pipes are mainly used plastic fittings, but there are also stronger versions of steel, cast iron, copper and brass. They differ in design and can be welded, threaded, press-connection. For plastic pipes are predominantly used compression fittings where the fixing clamp is a split ring of solid plastic material with notches, and the sealing - tightness of the sealing rings.
As well As other connecting devices, compression fittings come in several forms:
Before the water-pipe must first draw his pattern with all the fittings and valves. Flattened tube tends to curl, so it is attached with clamps or pressed in straight 2 days.
If you have chosen to install the HDPE pipe, installation often done with compression fittings.
Connections compression fittings are convenient to use when the installation of HDPE pipes in the country. The system is easy to assemble in the spring on the site and in the fall removed.
Plug-in connections in remote places are made.It is convenient to apply Electrometry with a built-in heater. The fitting connects 2 tubes, then turn on his heating and welding takes place with the formation of a permanent knot. Price of the device is high, but the method is effective and often used.
Despite the possibility of dismantling the compression fittings you should replace the rubber seals when re-installing. This will ensure high reliability design.
When installing the HDPE pipe, installation for diameter more than 40 mm should be preferably done by means of metal flanges. To do this, the edges of pipes cut with a pipe cutter at a right angle at the finished layout. Then welded polyethylene sleeve with collars, and they set flanges of metal. Another way is to mount the compression tube flange to lock the smooth polymeric portion of the joint. Then installed a conventional flange which is secured by studs and bolts with the same part that is installed on the end of the steel pipe.
Flange connection allows you to connect valves, regulators, valves and tubes among themselves.
In the same way as metal, can be welded HDPE pipe. Installation with your own hands produce with the help of special equipment with electric heating of the junction.
The Cost of installation of HDPE pipe by welding depends on the diameter, but to a value of 63 mm price is usually the same and is around 200 RUB over the joint.
When applying electric coupler installation costs are the same as when butt welding, but it's more expensive. In the end the cost is much better.
The Efficiency of the harvested water is tested by filling with water for 2 hours. The system then raises the pressure and maintain it for 30 min. Tubing inspect for leaks.
In the operation process, the system status is constantly monitored. With proper Assembly, it will operate long enough.
When installing the HDPE pipe, installation is done mainly by welding or compression fittings. If the rules for installation connections will be airtight and durable for many years.
