Insulated pipes with polyethylene shell

Insulated pipe according to GATS 34 204-88-002-98 Insulated Fittings according to GATS 34.015-2000

Insulated pipes are the design of the "sandwich" consisting of a steel pipe coated with the outer insulation of rigid polyurethane foam. The use of hard polyurethane foam (PUF) insulation of pipelines and heat water is dictated by the unique qualities polyurethanes, such as:

* lowest coefficient of thermal conductivity;
* durability (not less than 30 years);
* high technology processing;
* reliable corrosion protection of pipelines;
* ability to acoustic insulation;
* solonoski products of any size and configuration.

Insulation with polyurethane foam coating on steel surface of the pipe has a protective outer shell.
Insulated pipes with outer PE sheath designed for buried and underground piping, protects the layer of foam insulation from moisture, mechanical damage, prevents diffusion of polyurethane and provides a high degree corrosion protection.
Insulated tube with an outer shell of galvanized steel, designed for external ground pads pipelines, which compared with plastic tend not to the action of ultraviolet sunlight and other atmospheric phenomena. The shell depending on the diameter has a thickness of 0.55 to 1.0 mm, owns high strength and fill components are guaranteed to withstand pressure foaming polyurethane. In addition, the small width of the strip protects the pipe from vandalism: an extremely narrow band it is difficult to remove from the tube and use for other purposes.

The heat-insulated pipes, construction of external insulation has improved physical and mechanical properties, which allow to:

* keep the temperature of the pumped medium and to protect against corrosion of the external surface of steel pipes and fittings;
* without defects to transport any transport;
* withstands the action of groundwater, precipitation, solar radiation;
* provides high contact resistance, which ensures high efficiency with cathodic protection;
* maintains its protective properties on the life of the pipeline.

Scope:

* the heating system;
* water system.

Advantages:

* Protection of the external surface of the steel pipe from ground moisture, stray currents, rainfall and sunlight depending on types of pipeline construction.
* Lowest thermal conductivity among the insulators. Reduces heat loss in 2,5 - 3 times.
* No moisture absorption.
* High mechanical properties of the structure of insulated pipes allow the construction of pipelines ductless way that reduces capital expenditures by 30% and increases the pace of construction.
* The use of heat-insulated pipes and fittings reduces costs for operation, repair and reinstallation of the replacement pipe. Life insulated pipes not less than 25 years.
* No restrictions on the installation of heat-insulated pipes due to weather conditions.
