Pipes in PPM of isolation are used at the device of heating mains and highways of hot water supply. Advantages of use of penopolimermineralny (PPM) material for heat and waterproofings of steel pipes are caused by its unique heatphysical and operational characteristics. Which most precisely corresponds to climatic conditions of Russia, and almost in all respects surpass many other types of isolation of pipes applied now.
The pipe in PPM of isolation differs in long service life, low cost and simplicity of drawing this type of isolation on pipes. Therefore use of this production at construction of heating mains promises to customers a considerable economic benefit. The pipe in PPM of isolation is reliably protected from external corrosion thanks to what the heat conductors constructed of such pipes seldom fail.
Production, scope and characteristics
Penopolimermineralny isolation is strong material with very good adhesion to metal surfaces in this connection special processing of steel pipes before drawing PPM is not required. Only standard procedures of mechanical cleaning of pipes of pollution and processing are made by a flame which guarantee lack of foreign particles on the processed surface.
For drawing a protective layer of PPM the pipe is stacked in in advance prepared form, centered, and enter into a cavity between a form and a pipe the dosed number of special three - component structure. When mixing reagents there is a rough chemical reaction. The formed substance foams, repeatedly increases in volume and gradually hardens.
As a result the pipe is dressed in the protective cylinder from uniform porous substance. The PPM main useful property of isolation defining expediency of its use as the protective and isolating covering for steel pipes - low coefficient of heat conductivity. And also sufficient durability of this porous material.
The pipe in PPM of isolation is intended for construction of pipelines of all types. Isolation provides to PPM the minimum losses of thermal energy during delivery to the consumer. A source of additional economy is simplicity and low cost of isolation of joints between pipes. Except pipes, conclude branches and all applied shaped products in PPM - isolation.
Settlement service life of heating mains at which construction the pipe in isolation PPM was used is equal to 30 years. But really such heat conductors can be much longer operated successfully. Experts note that the pipe in PPM of isolation possesses operational characteristics which considerably surpass many other types of thermal insulation of pipelines:
- Simplicity of installation;
- Vapor permeability of thermal insulation;
- Lack of need of drawing on pipes of an additional layer of protection against corrosion;
- Installation and connection to the electronic system controlling moistening of a layer of thermal insulation is not required;
- High rates of durability;
- Temperature of the carrier is up to + 150 °C;
- The low cost of material in relation to its efficiency.
Advantages of PPM of isolation
Use of pipes in PPM of isolation allows to reduce twice losses of heat if to compare them to pipes in isolation from the mineral wool applied to these purposes earlier. Duration of operation of the pipelines constructed with use of pipes in isolation PPM makes 30 - 40 years as external corrosion practically does not threaten these pipes. The cost of construction of heating systems decreased by one and a half times, and operational costs - in eight. The pipe in isolation PPM used for construction of pipelines provides considerable economy of means of the customer at all stages of construction and operation of heating systems.
