Lab Gas Cylinder Room 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 pipelines and other gas pipelines can be installed on the same frame, with a spacing of not less than 0.25 meters. The oxygen pipeline should be above the other gas pipelines, which are not oxygen pipelines.

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 positioned above. Indoor pipelines should not be laid in ditches or directly buried. Avoid running through unsuitable rooms.

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

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

6. Metal piping should be used for the connection parts. 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 must not be used for gas pipelines. Other gas pipelines can be made of copper, carbon steel, malleable cast iron, and other materials.
