Simulation And Emulation Of Internal Resistance Heating Direct-Burried Heat-Insulated Pipe

Technology of direct-burried heating pipe have been admitted by all countries of world, not only because direct-burried heating pipe use insulating material of high quality and heat-insulated structure of high strength have solved difficult problems as heat-insulating property, compressive strength, water-proofing property and so on, but also give uses immense economic benefits and social benefits at reduce invest and cut down consumption. Recently years, widespread apply of direct-burried hot water pipe have been driven development of high temperature vapor heating direct-burried pipe, direct-burried high temperature heat-insulated pipe have good heat-insulating property, economy of energy, waterproof, antiseptic and remarkable economic benefits, beautify the environment, have special meanings to build modern heat net and to rebuild higher old cities. But, because temperature of high temperature vapor pipe is high, technology of direct-burried have lots of...
