Important factors that affect prefabricated buried pipe insulation energy-saving heating polyurethane insulation pipe, buried pipe insulation Development and application of more and more widespread attention around the world. After the 1970s, the production and application of universal attention abroad insulation buried pipe insulation, and strive to significantly reduce energy consumption, thereby reducing environmental pollution and the greenhouse effect. Foreign insulation industry has a long history, and new insulation materials also are constantly emerging. High temperature corrosion polyurethane insulation heating pipe, buried GB polyurethane foam insulation design and construction should pay attention to the problem of laying the heating cable pipe, size structure is completely identical with ordinary insulation polyurethane foam pipe insulation, special heating cables tight towel laying pipe outer wall parallel to the pipe, using point heating medium heat through steel. Just instantaneous power cable maximum heating power, long as the temperature is high, the cable PTC memory material resistance increases, thus the operating current and electric power also decreases oil pipeline corrosion pipe insulation, heat loss heat until power compensation system so only when the system is in a steady state temperature. When the ambient temperature decreases tended to decrease when the cable automatically increases power to automatically compensate for the loss, so that the system can Xiachu new temperature equilibrium. This compensation is a highly efficient heating section. Oil pipe insulation | Kodak steam pipe insulation (certified) | insulation provided by Kodak Building Materials Co., Weifang.
