Plastic pipes for water supply: size, price, selection

for devices water supply system Various materials can be used. Today, plastic pipes are quite popular for water, dimensions and rates that may vary over a fairly wide range. It can be difficult to make a choice in favor of a particular product. Offer to get acquainted with the peculiarities of plastic fittings, its costs and the recommended use of the area.

Regulatory and technical documents

Pipes used for the water supply must meet certain regulatory requirements. GOST 25151-82 specifies general requirements to the water system. Hygienic requirements for drinking water and the order of passage control is regulated by GOST 2874-82. Articles of polyethylene produced in accordance with the GOST 18599-2001 from PVC GOST P 51613-2000. There are other technical standards defining the procedure for water supply devices and lodging are certain requirements for the installation work. Parameters of free-flow devices are regulated by building codes.

Main characteristics

When selecting products for the plumbing device should focus on their characteristics. Parameters purchased product depend on the installation location. We offer to meet with the characteristics that should be taken into consideration when buying materials for the water supply.

The diameters of plastic pipes for water and other dimensions

In accordance with the regulatory requirements for plastic pipe 34 is installed in the size range of 10-1600 mm. The most widely used non-pressure product diameter 50-110 mm, a length of 8 m wall thickness -. 3.2 mm typically. In pressurized constructions diameter may be 63-315 mm.

The main overall dimensions of plastic plumbing products include:

1. Inner diameter.
2. Nominal diameter.
3. The wall thickness.
4. Length.

When selecting transverse dimensions of the installation location is taken into account. For outdoor system selected articles diameter 32-100 mm. For the interior of the material can be purchased with a smaller cross-section. For vertical risers enough diameter 32 mm for horizontal segments can purchase plastic pipe for water or a diameter of 16 25 mm.

Weighted

Weight per meter depends on the characteristics of the material used, and linear dimensions of the pipe itself. The average product meter 16 mm in diameter weighing approximately 100 g, a diameter of 25 mm - a little more than 200 g

Tip! To find out the estimated weight in kilograms, should find the volume (in cubic meters) and the resulting value is multiplied by 950.

strength

For water running pressure, The strength characteristics of the plastic used are in principle pressure. Products used must withstand the pressure generated within the water distribution system, as well as the external pressure generated by the ground.

Attention! In plastic pipes with high strength characteristics of the price will be higher.

temperature

The maximum working temperature is determined by the characteristics of the material from which produced water. If polyethylene is only + 45 ° C, then the cermet reaches + 95 ° C.

Advantages and disadvantages

Plastic pipe for water have a number of undeniable advantages:

The disadvantage is:

Fields of application

In plastic pipes rather wide range of applications. They are used not only for water supply devices, but also in other systems. We offer to meet with the main field of use of such products and their distinctive features.

Water pipes

Formed by different design long life. For its manufacturing can be used a variety of materials, depending on the destination and the place of performance of works. For domestic use commercially preferably polyethylene, polypropylene. In industrial plants are used for collective use of PVC products. Features of these materials and uses advised discussed below.

sewerage

for devices sewer system can be used pipe of PP, PVC, PE. Standardized dimensions make it possible to use a variety of plastic pipes for sewers. Dimensions and prices of these products are closely related: the greater the cross-sectional dimensions, the higher throughput and cost.

Opting for plastic pipes is due to:

Plastic pipe for heating

Opting for plastic contour heating systems It is due to:

Before you buy plastic pipes for heating, Should define the optimal diameter and type of system. This will depend on the capacity of the system and the level of heat loss. If the bandwidth is sufficient, it will be possible to refuse an extensive system. When the device of the heating loop forced circulation selected plastic tubes with smaller transverse dimensions: 8.10 mm. For systems with natural circulation of the product required a large cross section.

Kinds of pipes for water supply

For the manufacture of long products using materials with different characteristics. We offer to meet with existing kinds of pipes for water supply and features to make it easier to pick up material for their water supply.

Polyvinylchloride PVC pipes for water supply

Products made of PVC have sufficient strength and capable of withstanding low temperatures. PVC pipes for water have a number of advantages:

With the formation of tight connection can use PVC pipe for water, arranged on a floating ground.

Polypropylene pipes for plumbing

products from polypropylene characterized by resistance to chemical substances. They quickly mounted. Installation work can be carried out by hand. Environmentally friendly. They have a great life.

high rigidity polypropylene tubes plumbing forced to use a lot of rotary fittings the installation system. The high temperature undergo significant deformation. To avoid negative consequences, provides temperature compensators.

Manufacturers offer products of three kinds:

• PN 10 - for cold water systems and devices "Warm floor";
• PN 20 - for hot water supply. Universal products allowing heating up to + 80 ° C;
• PN 25 with a maximum operating temperature of + 95 ° C.

To improve strength characteristics and stabilization parameters PN 25 reinforced with fiberglass or aluminum foil. The reinforcing layer may be formed inside or outside.

Metallpolimery

Articles made from plastic consists of three layers: polyethylene PE-X, a thin aluminum layer and another layer of polyethylene PE-X. Plastic with a metal layer connected by special adhesive. Part of the polymer material gives them the flexibility and smoothness. Aluminum layer provides sufficient strength and reduces the amount of thermal expansion when heated. Metallpolimers able to withstand heating up to + 95 ° C. They are lightweight. Do not fear of corrosive media. Moving in a waterpipe water creates a minimum of noise.

The disadvantages Metallpolimers should include:

Aqueduct for connecting the elements together using compression or press fittings, characterized by high cost.

Polyethylene HDPE low pressure

There are two kinds: for industrial and drinking water. Thanks to the good elasticity sold in coils, which can significantly reduce the amount of used plastic fittings. Saves characteristics when cooled to -50 ° C. It has a long service life.

"HDPE pipes are unsuitable for hot water system, because their operating temperature must not exceed + 45 ° C".

The crosslinked polyethylene (PEX)

Processing of polyethylene under high pressure can qualitatively change the structure of the material. The resulting spatial structure confers plastic pipe improved mechanical properties. Products XLPE have high strength characteristics and can withstand high temperatures (up to + 95 ° C). They can be used for hot and cold water supply device. When mounting plumbing fittings using crimping.

Which pipe is better suited for water supply

Plastic products are gradually replaced by other materials. Deciding which pipes for water supply is better to consider the functional features of the mounted system. For domestic hot water polypropylene products suit. In cross-linked polyethylene pipes from similar functions, however, his price for the same amount will be much higher. Plastic products are superior in performance, but the price for them will be even higher.

In addition to the material, you should consider its size. The transverse dimensions affect the capacity of the system. Purchased plastic products should not be more than 15 mm. At the risers size must be greater than 25 mm.
