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 pipe insulation, special heating cables tight steel tube and towel The parallel laying pipes, the use of 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 is gradually reduced until the heat loss of the heating power compensation system, the system is in a steady state temperature pm. When the ambient temperature decreases tended to decrease when the outer sheath of black polyethylene jacket foam pipe insulation, pipe insulation 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. High temperature corrosion polyurethane insulation heating pipes Polyethylene black jacket foam pipe insulation, polyurethane foam pipe insulation Buried national standard engineering practice quality problems, the following questions should pay particular attention to the design and construction: First, design and construction, we must truly understand the heating pipes Buried way divided into compensation and no compensation Buried Buried in two ways, really two ways to master their works, characteristics and applications, in order to In the design of rational use of polyethylene foam yellow jacket pipe insulation, the construction of safe, reliable and economical. 1. We must first grasp the concept: there is compensation Buried way is by pipeline natural compensation and compensation (such as squares and bellows compensator) to solve the pipe heat elongation, so that the thermal stress to a minimum; no compensation Buried , simply put, it is the pipeline without any compensation measures when heated, but by the strength of the pipe itself to absorb thermal stress.
