Prefabricated polyurethane insulation pipe, hard foam directly buried insulation pipe factory

Description :

　　Polyurethane insulation pipe is composed of high-density polyethylene outer protective layer, polyurethane rigid foam plastic pipe and steel pipe. The insulation layer is made of rigid polyurethane foam with a density of 60kg/m3 to 80kg/m3, which can fully fill the gap between the steel pipe and the casing, and has a certain bonding strength, so that the steel pipe, the casing and the insulation layer form a solid whole. The polyurethane insulation pipe foam has good mechanical properties and thermal insulation properties. Generally, it can withstand temperature of 120, and can withstand temperature of 180 through modification or combination with other insulation materials

　　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.
