Price of direct buried polyurethane insulation pipe, manufacturer of polyurethane composite insulation pipe

Description :

　　Characteristics of polyurethane insulation pipe:

　　1. The insulation layer material adopts polyurethane foam according to the medium temperature in the pipe, and the use temperature ≤ 120 ℃ ester foam is the ideal insulation material.

　　2. The outer protective sleeve is extruded from high-density polyethylene material, which has high strength and good waterproof and anti-corrosion properties.

　　3. The foam insulation layer, inner steel pipe and outer protective pipe are closely integrated, and the shear strength between each layer is ≥.

　　4. The compressive strength of the insulation layer is ≥, ensuring that the insulation structure does not deform under the action of soil pressure and ground dynamic loads. Directly buried insulation pipes have high compressive strength, good anti-corrosion and waterproof performance, and long service life. They can be widely used in centralized heating, water supply, power plants, and refrigeration pipelines in cities, factories, and residential areas, and are suitable for direct burial laying.

　　Polyurethane insulation pipe mainly consists of three parts.

　　(1) Working steel pipes: According to the technical requirements of the conveying medium, seamless steel pipes, double-sided submerged arc spiral welded steel pipes are used.

　　(2) Thermal insulation layer: rigid polyurethane foam.

　　(3) Protective shell: Made of high-density polyethylene or fiberglass.

　　Application of polyurethane insulation pipe

　　Polyurethane insulation pipes are widely used in liquid and gas transportation pipelines, chemical pipeline insulation engineering, petroleum, chemical, central heating pipelines, air conditioning and ventilation pipelines, municipal engineering, etc. High temperature prefabricated direct buried insulation pipe is a type of direct buried prefabricated insulation pipe with good insulation performance, safety and reliability, and low engineering cost. Effectively solved the insulation, sliding lubrication, and waterproofing problems of prefabricated buried insulation pipes for 130-600 high temperature heat transfer in urban centralized heating. High temperature prefabricated buried insulation pipes not only have traditional trench and overhead pipeline technology and practical performance, but also have social and economic benefits, and are powerful measures for heating energy conservation.

　　Advantages of polyurethane insulation pipe

　　(1) Low engineering cost

　　(2) Less land occupation, faster construction, and favorable environmental protection.

　　(3) Jacket tubes save energy, resist corrosion, have good insulation performance, and have a long service life.

　　(4) Can be equipped with a leakage alarm line for safety. Once a leakage occurs in a certain part of the pipeline, the accurate location and degree of leakage of the insulation pipeline can be displayed on a dedicated detection instrument through the transmission of the alarm line, in order to notify maintenance personnel to quickly deal with the leaking pipe section and ensure the safe operation of the heating pipeline network.

　　Polyurethane insulation pipes are highly popular for their excellent performance, convenient construction, and long service life. Their structure consists of three parts: an outer protective layer, insulation layer, and anti leakage layer. The outer protective layer is made of polyethylene, fiberglass, or other materials. There are three types of laying methods: direct burial, overhead, and trench laying. Our company produces high-density polyethylene jacket pipes, polyurethane insulation pipes, direct buried insulation pipes, polyurethane direct buried insulation pipes, steel sheathed steel direct buried insulation pipes, fiberglass wrapped insulation pipes, polyurethane products and other insulation materials.
