Features thermal insulation of water pipes

How to choose the right insulation.

is easier to prevent than to correct.This expression is more relevant than ever, because if timely install insulation, this will avoid accidents and subsequent replacement of the system.By understanding some of the subtleties, such work can be done independently and without any financial cost.

According to the norms, pipes are laid at a depth of about 0.5 m Naturally, the pipe deeper -. The better.And what if the water pipe installation is made by land or in unheated rooms?That these structures require special attention, especially in such areas as the:

• sump water and putting pipes in the house;
• pumps, water meters and other outdoor equipment;

When buying insulation material, it is necessary to pay attention to some basic criteria that must comply with insulation:

• ease of installation, so that even a layman in this field could easily cope with this kind of work;
• durability, which achieved a good moisture resistance and tolerance to temperature extremes;
• FIRE, especially for structures located in the room.
• low thermal conductivity - an important factor in energy saving;
• leak, the loss of which affect the basic functions of thermal insulation;
• ratio "price-quality."This is exactly the case when the cheaper - the worse the quality.

types of thermal insulation materials.

modern chemical industry has reached such a high level that it is able to provide consumers with dozens of types of heaters of various materials.On what to stop, depending on the financial possibilities of customers and applications.

most common today are:

• glass (mostly for plastic pipes).Its main drawback - low density, so it is necessary in a complex with it the use of additional materials, such as roofing felt;
• insulation made of basalt (have the shape of a cylinder).It requires additional insulation in the form of tar paper or glassine.The main advantage - the ease of installation;
• Styrofoam (polystyrene) is most popular because of its low cost and the possibility of recycling.

methods of laying insulation.

easiest to install is glass wool, which just wrapped tube.Heat-wound adhesive tape for fixing and finally it all enveloped roll roofing material.

Styrofoam shell or basalt wool attached on top of the pipe with an offset of approximately 10 cm from each other.Pre-fixing is carried out with tape.Roofing felt applied on top of the shells, which in this case serves as protection from mechanical damage.

Additional methods of pipeline protection.

One of the alternatives is to protect pipes from freezing, is the knowledge and application of the laws of physics.Namely, the increase in water pressure to 3 atmospheres, at precisely this index it is excluded the possibility of freezing.You can do this by setting a special receiver.

Insulation of heating cable.Suffice it an expensive way compensates for high efficiency.Power cable such ranges of 15-25 W / m pipe 1.The modern market of building and sanitary materials offers a range of cables and accessories to the already existing inside the wire.
