Gas system construction of clean operating room purification project
Release time:2020-01-16 source:
The working pressure of various gases in the gas system construction of clean operating room purification project is generally not higher than 1MPa. The main gases include clean air, * gas, special gas, medical gas, combustible gas, inert gas and vacuum suction.
1. The pipe material and accessories of the gas system shall be selected according to the design requirements. At present, seamless stainless steel pipe and degreased copper pipe are mainly used, while galvanized pipe or stainless steel pipe are generally used for negative pressure suction. The inner surface of the pipe shall be smooth, wear-resistant and the surface has little effect on adsorption and desorption of gas. The pipes shall be kept indoors without overlapping. The pipes shall be free of defects such as crack, shrinkage, slag inclusion, tumor, folding, heavy skin, rust spot, surface damage, etc.
2. The installation of the pipeline system shall meet the relevant design requirements. If there is no requirement in the design, it shall be laid at a height that is not easy to be collided by the personnel, or there shall be protective devices. The connection parts of the pipeline should be finished products. Before installation, degreasing should be carried out in accordance with the relevant provisions. The degreasing should be carried out at a place far away from the clean room and the safety and environmental protection of the operators should be well done.
3. The pipes passing through the enclosure into the clean room shall be provided with casings, and the pipes in the casings shall not be welded or jointed. Upon completion of construction, purging and air tightness inspection shall be carried out as required.
4. For pipes required for grounding, multi-core conductive jumper must be connected between flanges.
5. The leakage rate of the gas pipeline shall be checked after the air tightness test is qualified. The leakage rate shall not exceed 0.5% after the design pressure is maintained for 24 hours, and the test shall be conducted after the leakage is allowed to be plugged.
