Detailed introduction of gas drain

First,Why use a gas drain?

In the process of gas transportation and combustion, the condensed water in the gas pipeline will affect the normal operation of the gas transportation equipment and the gas combustion equipment. If the condensed water cannot be discharged out of the gas transportation pipeline in time, the gas transportation equipment will be damaged and the gas combustion equipment will be damaged. abnormal, and even endanger personal safety.

Second, the role of the gas drain

The function of the gas drain is to collect and discharge the condensed water in the gas pipeline.

It is mainly composed of a drainer body, an anti-leakage device and a heat preservation device.

When the pressure of the gas pipe network fluctuates or the water level of the drainer decreases due to other reasons, causing gas leakage, the leakage prevention device of the gas drainer can prevent the leakage of gas and prevent the occurrence of vicious accidents such as gas fire and poisoning.

Third, common types

1. According to the form of heat preservation, it is divided into steam tracing and electric tracing

Steam tracing gas drain: It relies on the steam pipe wound on the outside of the cylinder, and the steam is passed through for heat preservation in winter.

Electric heat tracing gas drain: It relies on the electric heat tracing tape wound on the outside of the cylinder, and it is energized in winter for heat preservation.

2. According to the size of the installation space, it can be divided into vertical and horizontal

The height of the vertical type is generally about 1200mm, and the height of the horizontal type is generally about 600mm.

The gas drain can quickly, tightly and accurately cut off the gas to be leaked, and even when there is no water accumulation in the overpressure protection, it can still cut off the overpressure gas, automatically identify, and do not require any power; the drainage is smooth, which can prevent slag clogging and prolong the cleaning cycle. More than twice the time (usually 1-2 years), and can mechanically clean up the dead corners of slag; especially the leakage prevention device of the drain, which can block all kinds of overpressure gas, prevent moisture from volatilizing, and improve the height of the water seal.
