Lab Cylinder Storage Room Gas Pipeline Installation Standards

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 installed on the same framework, with a spacing of no less than 0.25 meters, and the oxygen pipeline should be positioned above the other gas pipelines, excluding the oxygen pipeline.

3. When piping is laid parallel to flammable gas piping, the distance between them must be no less than 0.50 meters. When crossed, the spacing should not be less than 0.25 meters. When laid in layers, the piping should be placed above. Indoor piping should not be laid in ditches or buried directly. Avoid passing through unsuitable rooms.

Gas pipelines should not be mounted on the same framework as the cables and wiring laid for the store.

5. Gases should be conveyed through seamless steel pipes. Pipes for gases with purity of 99% or higher should be made of stainless steel, copper, or seamless steel pipes.

6. The connection sections of pipelines and equipment should be made with metal pipes. For non-metallic flexible hoses, polytetrafluoroethylene (PTFE) pipes and polyvinyl chloride (PVC) pipes should be used instead of rubber hoses.

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