5. Gas distribution lines (气体管路)
5.1. All gas distribution plumbing shall be fabricated from high quality, fully annealed, seamless type stainless steel SS-316L. Copper tubing shall only be used for final termination of gases at are where purity is not a major concern e.g. at fume hoods.
所有气体管路都由高质量的、完全退火型、无缝连接的不锈钢管SS-316L组成。铜管只使用在气体管路的末端，对气体纯度不是太严格要求的地方（比如通风柜）。
5.2. All valves, regulators and gauges proposed for the gas distribution lines shall be of good quality, stainless steel type, made for specific gasses and shall be provided with standard fittings.
所有的管路、阀门、压力表都由高质量的不锈钢构成，并且都是标准配件。
5.3. All main gas line shall be at least 3/8” diameter (1/2” for plant/instrument air and N2 lines). While nearing the points of use, the gas lines shall be stepped down progressively to 1/4” tubing.
所有气体干管的直径为3/8英寸(仪器空气干管直径为1/2英寸)。管路末端，直径为1/4英寸。
5.4. All gas lines shall be run below ceiling and then delivered to island benches via service columns. Once on the benches, gas lines shall be run concealed behind laboratory benches and utility service columns. These gas lines shall be easily accessible.
所有管路在天花板下面布设，并通过服务柱到中央台。边台的气体管路隐藏在实验工作台后面服务通道内。
5.5. Highly combustible gases like acetylene shall be run individually away from other gases.
易燃气体，如乙炔， 需要和其它气体分开，单独引入。
5.6. For all gas lines, all joints shall be orbital welded to minimize pressure fittings. Where “T” or “reducing union” is required pre-orbital welded “T”s and “reducing unions” shall be used. (Swagelok or equivalent) type fitting shall only be used where connections are made to valves and regulators.
所有气体管路的连接为无缝焊接。连接到阀门或调节装置时，才可以使用压力配件。
5.7. A main gas panels with an isolation valve, a step-down pressure regulator and a pressure gauge for every gas line shall be provided in the every lab area. For gas lines servicing similar instrument, there should be another set of step down regulator at every service column for point of use gas pressure control.
每个实验室都要有单独的阀门、减压阀门、压力表。此外，对于供应多台分析仪器的气体管路，另外还需气体压力控制指示装置。
5.8. Gas lines coming onto benches shall be equipped with individual isolation ball valves.
引到工作台的气体管路将安装单独的球阀来控制。
5.9. 1/8-inch outlet points, on each GC benches, for gasses cylinder Air, Nitrogen, Helium and Hydrogen etc. shall be provided with spacing along the bench evenly. A carrier gas filter system is recommended to be installed on the Helium line (He).
气相色谱工作台上均匀的排放各种气体的出口龙头，管径为1/8英寸。在氦气管路前面建议安装气体净化装置。
5.10. For instrument with individual pressure regulating needs, gas outlet points on benches shall be terminated with an individual regulator bracketed to the bench.
工作台上气体出口龙头由单独的阀门来控制。
5.11. All gas outlet points shall be terminated with a stainless steel toggle valve with a final reducer of compression joint of 1/8” outlet.
所有气体出口龙头为不锈钢toggle 阀门。
5.12. Each gas line shall be clearly labeled (colour and written code) for every 1.5-meter distance. Labeling shall also indicate the direction of gas flow.
气体管路每隔1.5米的距离，都要有明确标示，同时指示气体的流向。
5.13 All gas line support brackets and tie rods will be galvanized type.
气体管路所有的支架都要镀锌防腐。
5.14 There will be a support every 1.5 meter or less. Support distance will be determined by the tubing with the smallest diameter.
每隔1.5米左右，气体管路就需要有支架。另外根据气体管路弯曲的直径，设置合适的支架位置。
5.15 All bends will be supported independently both sides.
所有弯曲处都要有支撑。
5.16 All “U” bends (or 180o bends) will be supported in the following manner:
所有“U”型弯曲根据以下情况，需要有支撑.
