#Electric heat tracing# system is mainly used for heat tracing insulation of various pipelines and equipment, in addition to the heat tracing insulation of common water pipes and fire pipes, electric heat tracing can also be used in petroleum, chemical, thermal power plants and other places that need to use heat tracing pipelines.
Electric heat tracing
The initial design of the electric heating system should fully consider the local ambient temperature to ensure the electric heat tracing insulation effect; According to the actual situation to determine the power of the electric trace, it is necessary to wipe stains, dust and oil and water stains during the installation process to prevent the electric cable from being fixed firmly. Electric heat tracing systems can provide temperature demands ranging from tens to hundreds of degrees, including temperature-critical vapor purge pipes.

Most of the steam purge areas exist in the petrochemical industry, the temperature demand of steam purging can reach several hundred degrees, and it is difficult for the general electric cable to achieve such a high temperature demand, therefore, for the area with steam purging, MI armored electric heat trace will generally be selected.
MI armored electric heat trace
MI armored electric heat trace is a solid body with high density formed by multiple stretching of single or multiple alloy wires, mineral insulators and metal pipe sleeves. MI armored electric heat tracing can meet the needs of high temperature conditions and high heating power, the maximum withstand temperature can reach 600 °C, and the outer sheath is stainless steel metal layer, can withstand temperature up to 1000 °C, has excellent mechanical strength, corrosion resistance, suitable for heat tracing and frost protection in the steam purge area.
