Benefits of electric water heating and antifreeze insulation for gas water seals

Information source: Anhui Cable Group Views: 2169 Time: 2017-03-03

Gas water seals are commonly used in power, petroleum, chemical and other places. It can effectively isolate the gas from the outside world, and when the water vapor in the gas is too large or overpressure, it plays a role of drainage and decompression. This device that isolates gas from the outside world mainly balances pressure by the height of the water level inside. Icing can occur when the ambient temperature is low. In order to make the gas water seal play the role of overflow and decompression, without bringing hidden danger to normal production, it is necessary to prevent the water in the water seal and each inlet and outlet pipe from being blocked by freezing. According to the past conditions, steam tracing is often adopted. The construction cost of this method is too high, the daily maintenance workload is also large, and the insulation effect produced is not very satisfactory. Here we recommend to users the method of electric heat tracing and antifreeze, as long as the site is connected to 220V or 380V power supply can be easily implemented.
Wrap the heating tape around the outer wall of the gas water seal, so that the outer wall of the water seal and the heating tape are kept flat and flat, and then stick the aluminum foil tape along the belt (as shown below). The outer layer is supplemented with insulation cotton and protection, so that cold winters can no longer be affected by freezing. For specific installation methods and precautions, please refer to the manufacturer's installation technical manual .

Installation of gas water-sealed electric heating and anti-freezing heat insulation


Set the temperature of the electric heating cable within the working temperature range. If precise temperature control is not required and a temperature control device is not required, it is recommended to use a self-controlling electric heating cable. Through this antifreeze and heat insulation method, the water in the gas water seal can always be kept within the working requirements. It ensures that the excess water vapor in the gas is discharged in time, and the pressure can be reduced in time when the air pressure in the pipeline equipment is too high, which will not affect the normal production in winter again.
The advantages of using electric heat tracing for gas water seals as antifreeze insulation are: 1. easy to install and operate with better results; 2. no pollution, safe and environmentally friendly; 3. reducing a large amount of routine maintenance work, saving maintenance costs .
