Product Information
Prefabricated directly buried polyurethane insulation pipe is an efficient, safe and economical pipeline system, which is widely used in infusion pipeline network, chemical pipeline insulation engineering, petroleum, chemical industry, central heating pipe network, central air conditioning ventilation pipeline, municipal engineering and other fields. The piping system consists of a working steel pipe layer, a polyurethane insulation layer and a high-density polyethylene protective layer. It has the following characteristics and advantages:
Structure composition:
Working steel pipe layer: According to the design and customer requirements, generally choose seamless pipe, spiral welded pipe or straight seam welded pipe, after advanced shot peening rust removal process, to achieve a certain level of rust removal and surface roughness.
Polyurethane insulation layer: The high-pressure foaming machine is used to inject rigid polyurethane foam into the cavity formed between the steel pipe and the outer protective layer to play the role of waterproof, heat preservation and support the self-weight of the heat net.
High-density polyethylene protective layer: protect the polyurethane insulation layer from mechanical damage, anti-corrosion and waterproof.
Advantages and features:
Good thermal insulation performance: It effectively solves the thermal insulation problem of high-temperature heat transfer prefabricated directly buried thermal insulation pipes, and is suitable for high-temperature heat transfer from 130 ℃ to 600 ℃.
Safe and reliable: Directly buried heating pipeline technology improves the safety and reliability of heating pipelines.
Low project cost: Compared with other insulation materials, prefabricated directly buried polyurethane insulation pipe has low project cost and good economy.
Wide working temperature range: The working temperature range is -20 ℃-120 ℃, which can adapt to low temperature environment and withstand the heat of high temperature water.
Environmental protection and energy saving: it has the characteristics of small heat loss, energy saving, reducing the impact on the environment, and is conducive to environmental protection.
Long service life: It has good anti-corrosion and insulation properties to ensure the long-term stable operation of the pipeline system.
Use:
Mainly used for thermoelectric heating engineering pipelines, air conditioning water circulation pipelines, hot spring drainage pipelines, etc. Due to its safe and reliable characteristics, this kind of pipe is now mainly used in many residential heating fields.
The application of prefabricated directly buried polyurethane insulation pipes not only improves the efficiency of the heating system, but also reduces the maintenance cost. It is an ideal choice for modern heating systems.
