Insulation for pipes

With the arrival of winter emergency services oftenfaced with the problems that arise due to pipes freezing. Cold and severe frosts do not spare even the highest-quality and durable pipes - they burst. As a consequence, it is required to replace them, and the time and money. Those who do not want to be sad fate befell the stay in the winter without water, and other facilities necessary to carry out work on warming. Fortunately, the market offers a great variety of different materials that can be used as insulation for pipes, to ensure their protection from frost.

Applying for insulating pipes or that typeinsulation, should take into account its properties, characteristics and conditions of the environment in which you plan to use it. For example, in laying of sewer systems based on many factors, and certainly made warming. As sewage systems are underground communications, we can not immediately see the defects, which can lead to serious trouble, so choose the heater for the sewer pipes is with great care, or entrust it to professionals.

Since the effectiveness of the procedure depends on the type and quality of thermal insulation materials, it is necessary to learn more about the criteria that are worth paying attention.

The main requirements for the heater

Easy installation. Especially important for those who plan to carry out work on warming the pipes themselves and not with the builder.

Durability. The better the insulation, the longer it will be able to carry out its functions, the system will be better protected and less need to mess with re-warming.

impermeability. If the heater is waterproof, it is unlikely he will save the pipe in the winter.

In attention should be taken and the operational and technical characteristics of different types of insulation: thermal conductivity, high temperature resistance, etc.

Materials for thermal insulation of pipes

Glass wool as the insulation of pipelines

Quite popular material, produced by manymarks in the form of mats, rolls or panels of various sizes, thickness and density. It meets all the requirements that apply to thermal insulating materials, however, is not always easy to install and requires no additional insulation and sealing, which increases the cost of the works and their duration. Most often used for plastic pipes.

Practical basalt fiber

Basalt fiber has all the necessaryproperties, to call it an excellent material for insulation. From it are made basalt wool, which is characterized by low water absorption coefficient and excellent thermal insulation properties. Sometimes this fiber is used for the manufacture of special cylinders that are simply put on the pipe and are used for their insulation, no skills for such a procedure is not required. Some confuse rather high price of this material, but it pays off long product life.

The foam "shell"

The foam "shell"

Universal foam (expanded polystyrene)

This material is economical, versatile andIt has the required performance properties. He enjoys well-deserved popularity and is often used when you want to perform a water pipe insulation, for example, in a private house. It is used for insulation of pipes indoors and outdoors. Polystyrene "shell" that are interconnected can be with or without an outer coating. Installation is easy. For warming the angles in the water system suitable shaped shells of different shapes.

Advantages of polyethylene foam

A relatively new material. At present, there are two kinds of it - physically crosslinked and chemically cross-linked polyethylene foam. The most widely circulated last because of its low price. This material is used at temperatures ranging from - 40 to + 90 ° C.

Relative humidity virtuallyplays a role, it may be up to 100%. Due to the special structure of polyethylene foam is elastic and has a high thermal resistance. This insulation is widely used for self-insulation of water pipes and heating pipes made of different materials.

penofol foiling

Penofol foiling - a new generation of thermal insulation

Progressive foiling penofol

Two sided Refers to a new type. Structure: polished aluminum foil and the base of polyethylene foam. There are several types: those that have foil on one side; on both sides or combined - on the one hand a foil, and on the other adhesive surface. This feature makes it possible to select the material that is most appropriate in a particular case. It goes on sale in rolls.

To summarize

Today, insulation of pipes can be carried outdifferent methods and materials that differ both in composition as well as by applying the technology and structure. Manufacturers offer a wide range, and it is important to consider when buying the key requirements for a heater and pay attention to its performance characteristics. It is reasonable to give preference to no more than a cheap option, but more efficient and qualitative because the repair of the pipeline, in case of breakage, will be much more expensive. Choose a heater should be based on three factors: the first - the location of the pipe (street, premises); second - ease of installation (the simpler the better); the third - the price. We hope that these suggestions will help you efficiently and on time to perform insulation of pipelines.
