Increase in prices for heat carriers becomes the best incentive that owners of owner-occupied dwelling, already at stage of its design, thought over not only the scheme of utilities, but also how to provide thermal insulation of its basic elements – the equipment and pipelines. Correctly made thermal insulation allows to preserve up to 95-97% of heat which would be in vain spent for heating of the street and utility rooms.
For what thermal insulation of pipelines and the equipment is necessary
As a rule, the equipment ensuring functioning of the engineering systems which are responsible in owner-occupied dwelling for comfort and heat: heating boilers, ventilation units, boilers, heaters and so forth, are installed not in rooms, and in specially allocated rooms in residential building or in the economic block located separately. Therefore the heating services heat carrier, hot water or warm air of system of aeration on the way to consumers – premises, move on external pipes which are laid underground or on its surface and also in non-residential premises. It turns out that part of useful and precious heat is spent for nothing, and heatlosses can be up to 100%.
For energy conservation and resources it is necessary to reduce heat waste, having provided warming of both the equipment, and pipes. This expensive and troublesome business, but economic effect of it considerable – modern thermal insulation materials and technologies will allow to minimize the number of losses, especially, if to consider these works on projecting phase of life support systems of residential building. Competent approach to this question will allow not only to keep heat, but also to protect steam lines, air ducts and pipelines of conditioning systems, cold water supply, refrigerating appliances from freezing during the winter period and also from formation of condensate which can become the reason of corrosion of metal pipes. Anyway, thermal insulation allows to prolong terms of operation of utilities and to cut down costs on their service and repair.
Requirements to thermal insulation materials
The main requirements which consumers impose to the materials which are applied to thermal insulation are the acceptable cost, reliability, efficiency, simplicity of mounting and long term of operation. These requirements are capable to provide cumulative characteristics which these materials have to possess. So, they have to have the water-repellent properties providing tightness and excluding corrosive processes between surface of pipes and material of heater. Besides, heat insulators have to be fireproof, have low heat conductivity and the high heatpreserving qualities, to be resistant to external chemical and biological influences. Many thermal insulation materials which are released in the form of casings and cylinders of different diameter, technical mats, rolls and special bandages have these characteristics.
The materials which are used for thermal insulation of pipelines and the equipment
Frothed polyethylene which for thermal insulation of pipelines and is produced in the form of tubes with one or two longitudinal sections belongs to some of the most popular materials. Inside diameter of these tubes different therefore it can be used for pipes of several standard standard sizes. Foamy polyethylene is the eco-friendly and safe material which is characterized by the increased resistance to temperature drops, mechanical damages, biological and chemical influence. It is used both in thermal systems, and for isolation of refrigerating appliances and conditioning systems.
Getting thermal insulation materials, do not forget to get also the special accessories allowing to record reliably them on pipelines: the adhesive tapes, clip-on earrings gluing tapes.
For warming of pipes and the equipment also use frothed rubber which is produced not only in the form of tubes, but also in the form of plates. The advantage of this material is the increased fire safety, it has ability to self-attenuation. Technical mats from mineral wool – the inexpensive insulating material which is traditionally used for pipes and the equipment of conditioning systems, heating and water supply. Their application is especially reasonable for large diameter pipes. Technical mats which are issued the industry are lamellar, foiled and proshivny, all of them differ in the long term of operation. Basalt mineral wool is applied to production of heat-insulating cylinders which can be without covering or are covered with foil, to have galvanized surface.
The foiled thermal insulation materials allow to eliminate heat waste and to minimize them at the expense of the created reflecting effect. They also possess Paro - water - and heat-insulating properties.
It is possible to carry to the novelties which have appeared in the construction market recently folgoizol, folgokholst and also aerogels and liquid thermal insulation materials. Gel and liquid mixes can be used for any equipment and pipes of any diameter, they guarantee lack of condensate and corrosive processes, providing protecting cover even in the most hard-to-reach spots.
