Standard Pipeline Installation in Laboratory Gas Cylinder Room

Pipelines for conveying dry gases should be installed horizontally. Pipelines for conveying wet gases should have a slope of not less than 0.3% and incline towards the condensate collector.

2. Oxygen and other gas pipelines can be mounted on the same framework, with a spacing of not less than 0.25 meters, with the oxygen pipeline positioned above the other gas pipelines, excluding the oxygen pipeline.

When laying pipes parallel to combustible gas pipelines, the distance between them must not be less than 0.50 meters. When crossing, the spacing should not be less than 0.25 meters. When laying in layers, the pipes should be placed above. Indoor pipes should not be laid in trenches or directly buried. Avoid passing through unsuitable rooms.

Gas pipelines should not be installed on the same frame as the cables and wiring laid in the store.

5. Seamless steel tubes should be used for gases. Pipes for gases with a purity of 99% or higher should be made of stainless steel, copper, or seamless steel tubes.

6. The connection sections of pipelines and equipment should be made with metal pipes. For non-metallic flexible hoses, polytetrafluoroethylene pipes and polyvinyl chloride pipes should be used in place of rubber hoses.

Valves and accessories materials: Copper materials shall not be used for gas pipelines. Other gas pipelines can be made of copper, carbon steel, malleable cast iron, and other materials.
