Problems that should be paid attention to in the design and construction of polyurethane thermal insulation directly buried heating pipe: OK. The size and structure of the pipe for laying the heat-tracing cable is exactly the same as that of the ordinary heat preservation pipe. The outer wall of the special heat-tracing cable scarf steel pipe is laid in parallel with it, and the point heat is used to heat the medium through the steel pipe. At the moment of just electrification, the cable heating power *, with the increase of temperature, the resistance of PTC memory material in the cable increases gradually, so the working current and electrothermal power also gradually decrease, until the heat loss of the heating power compensation system, so that the system temperature is in a stable state. When the ambient temperature decreases, the cable power increases automatically and the loss is compensated automatically, so that the system can be balanced at the new temperature. This compensation heating method is efficient and economical.
