On construction technique for self-regulating electric heat tracing of pipelines

The paper introduces the construction technique for self-regulating electric heat tracing of pipelines,illustrates from the craft principle,the construction craft,and some attentive problems,analyzes the social and economic benefits of the technique,and points out the construction technique for self-regulating electric heat tracing can eliminate some frozen hidden hazards,avoid the leakage and sinking problems effectively,so it has better.
