Gas line means the line connecting the cylinder to the instrument terminal

Gas pipeline refers to the pipeline connecting the gas cylinder to the instrument terminal, which is generally composed of gas switching device - pressure reducing device - valve - pipeline - filter - alarm - terminal box - regulating valve and other parts. Conveying gas for laboratory instruments (chromatography, atomic absorption, etc.) gas, high purity gas, gas engineering co.

A one-way valve is installed at the outlet of the cylinder to avoid mixing air and water when the cylinder is replaced. In addition, a pressure relief switch ball valve is installed at one end to discharge the excess air and water before connecting the instrument pipe to ensure the purity of the gas used by the instrument.

All gas lines are made of high-quality, fully annealed, seamless stainless steel (BA class). Copper pipe is only used at the end of the gas pipeline, where the gas purity requirements are not too strict. (fume hood, for example). Gas pipeline installation shall not be laid on the same shelf as cable and conductive line.

Flammable gases such as acetylene need to be introduced separately from other gases. If hydrogen pipelines are laid parallel to other combustible gas pipelines, the spacing should not be less than 0.5m. The time interval for cross laying shall not be less than 0.25m. Hydrogen pipe shall be located above when layering. The compressed air has a purification device to filter impurities and water in the pipeline. This purification device needs to be connected in parallel and isolated by a separate valve to facilitate maintenance of the filter device.

Seamless steel tube: most enterprises in the first installation, this is the first choice, after all, the cost is much lower. But it is easy to corrode oxidation, easy to rust, and then pollution of compressed air, which impurities will damage downstream gas equipment, and affect the quality of products. Rust adheres to the inner wall of the pipe for a long time, resulting in reduced flow rate and pressure, which is ultimately a waste of resources.
