Introduction to heat tracing sampling compound piping

The heat tracing and sampling composite cable is an important part in the monitoring system. It is composed of a group of corrosion-resistant and high-performance resin conduits, high temperature constant power electrical belt or self-limiting electrical belt and compensation cable. It is added with imported raw material insulation layer and coated with polyethylene or PVC sheathing. The constant power electric belt adopts platinum resistance temperature probe to control the temperature. The automatic temperature limiting function of the self-limiting temperature electric belt can ensure that a certain temperature is maintained in the sampling tube, so as to ensure that the collected samples are consistent with the initial value as far as possible, and finally ensure the continuity of the monitoring system. Collect sample gas accurately. According to different ambient temperature, can use appropriate tracking belt, as well as compensation line, power line, etc. Can also be added according to user requirements.

3.z.u small fixed distance: 2m vertical direction, 4m horizontal direction.

Installation precautions of heat tracing sampling compound pipe

It is strictly prohibited to twist and drag on the ground during the construction process. Only after the contact is installed, it is allowed to remove the tube head sheath. The end of the tracking belt should be closed to prevent the two lines of the tracking belt from short-circuiting and burning the tracking belt. The shield layer of the tracking belt shall be grounded to prevent electric shock. Special intermediate junction boxes or power junction boxes should be used at one end of the power supply to avoid potential accidents. Install the leakage protector for the distribution switch.
