As an important chemical raw material, liquid ammonia plays an important role in industrial production. In winter, liquid ammonia pipelines will freeze and block. In order to ensure the normal operation of industrial production, the liquid ammonia pipelines need to be insulated and heated. Liquid ammonia is a special chemical substance that has the risk of cracking and exploding when exposed to high temperatures. In this regard, we can choose heating tape for antifreeze and heat preservation.

During the installation of heating tapes in liquid ammonia pipelines, special attention should be paid to the following points:

1. The selection and design of liquid ammonia pipeline heating tape should be based on the actual pipe material, pipe diameter, medium and other parameters that need to be heated. At the same time, factors such as the use environment and safety performance should also be taken into consideration.

2. When installing liquid ammonia pipeline heating tape, it is necessary to ensure that the surface of the pipeline is dry, free of debris and rust, so as not to affect the heating effect and service life.

3. The installation location of the liquid ammonia pipeline heating tape should be as far away as possible from environments such as high temperatures, strong magnetic fields, corrosive gases, etc. At the same time, maintenance and repair factors also need to be taken into consideration.

4. When installing the heating tape of the liquid ammonia pipeline, attention must be paid to the installation and fixation of the insulation layer to avoid accidents such as damage to the heating tape and leakage of electricity.

5. The control system of the liquid ammonia pipeline heating tape needs to be selected according to actual needs. At the same time, factors such as the matching of the control system and the pipeline heating tape need to be taken into consideration.

6. When using liquid ammonia pipeline heating tape, it is necessary to regularly inspect and maintain the heating tape and its accessories, discover and deal with potential safety hazards in a timely manner, and ensure its normal operation and service life.

7. Reserve sufficient wiring length at the head end, tail end and the middle where wiring is required to facilitate installation and maintenance.

8. When wiring the electric heating tape, ensure the correct connection between the heating tape and various accessories to prevent short circuit.

In short, there are many things that need to be paid attention to when installing heating tapes in liquid ammonia pipelines. They need to be selected and installed in strict accordance with relevant specifications and standards. At the same time, daily management and maintenance need to be strengthened to ensure their safe and reliable operation.
