What are the requirements for the pipeline installation of the composite gas detector?
In many places in our lives and in industrial production, harmful gases are produced that endanger personal safety or may have adverse consequences. The composite gas detector is an indispensable test instrument, which can prevent environmental pollution early and ensure the safety of human life.
Composite gas detectors are usually used to detect toxic, harmful or combustible gases, usually used in biochemical, pharmaceutical, construction and other industries, while combustible gas detectors are usually used for gas environment detection in coal, petroleum, chemical, fuel and other industries. Different industries and different occasions have different detection standards, and different gas detection standards are also different. When choosing a good gas detection instrument, please pay attention to the use of the instrument according to the purpose and use occasion.
Before installation, all instrumentation tubes and fittings for oxygen channels must be strictly degreased and treated with carbon tetrachloride or alcohol. For the detection pipeline of the lubricating oil system, attention should be paid to removing the internal scale and impurities to keep the lubricating oil clean. After installation, the lubricating oil in the pipes must be repeatedly circulated using an oil pump for further cleaning. Inspection piping can only be installed after installation of equipment and process piping. Its installation quality will affect the measurement accuracy of the instrument, so what are the requirements for the pipeline installation of the composite gas detector?
1. For some outdoor detection pipelines where the measured medium is liquid, in order to prevent the pipeline from freezing, freezing and rupture in winter, heat insulation measures must be taken. Steam or electric heating can be used for insulation in sites with lower ambient temperatures. Often, asbestos rope or straw rope can be wrapped around the pipe.
2. For the detection pipe whose quality is moisture, a condensate removal device should be installed at the lower part of the pipe to prevent liquid from accumulating in the pipe; for the detection pipe whose measured medium is liquid, when the pipe and the instrument are located at the measuring point , consider installing an empty valve at a high point in the pipe to prevent a small amount of gas from accumulating in the pipe.
