氧氮氩碳，一站配齐O₂, N₂, Ar, CO₂ — one stop
工业气体设备：汇流排、配比柜、终端箱按介质选材，氧、氮、氩、二氧化碳在车间一次配齐。Industrial gas equipment: manifolds, mixing panels and terminal boxes matched to the medium.
产品概述Product overview
工业气体设备的共性是“接口多、气体杂”：同一车间可能同时用氧、氮、氩和混合气，每种气体的阀门口径、材质禁油要求、放散方式都不同。成套配置时先按气体种类分线，再按用气峰值定集装格数量，最后按纯度要求选阀与管材。Different gases need separate lines; frame count follows peak demand; valve and tube selection follows purity.
常用组合：气瓶集装格（15 MPa）+ 汇流排 + 减压阀组 + 充装排；混合气场合加二元/三元配比柜，配比精度按工艺要求定。低温液体场合则接低温储罐、低温泵与气化器。Typical sets: 15 MPa frames, manifolds, regulators and filling headers, with two- or three-gas mixing cabinets.
工作原理：五种气体，五套逻辑Working principle: five gases, five sets of rules
工业气体成套设备看起来都是“管子+阀门+容器”，实际每种介质的安全逻辑完全不同。氧气怕油、怕流速过高；氢气怕泄漏与氢脆；氮气与氩气本身不燃但会置换氧气造成窒息；二氧化碳高压下会相变、低温时会干冰堵塞。Industrial gas packages all look like pipe, valves and vessels, yet each medium has its own safety logic. Oxygen hates oil and high velocity; hydrogen brings leaks and embrittlement; nitrogen and argon are inert but displace oxygen and asphyxiate; CO2 changes phase under pressure and plugs with dry ice when cold.
因此成套设计的第一步不是画管路，而是确认介质、纯度、压力、流量与使用方式（连续/间歇、单点/多点），再决定容器形式（汇流排、集装格、储罐）、材质、阀门与安全附件。The first step in packaging is therefore not routing but fixing medium, purity, pressure, flow and duty — continuous or intermittent, single point or multi-point — then choosing vessel form (manifold, bundle, tank), materials, valves and safety devices.
集中供气还要算最远点压损与同时使用系数。多台设备同时用气时，总管流量不是简单相加；压损算大了会末端压力不足，算小了则投资浪费。Central supply also needs the pressure loss at the farthest point and a diversity factor. Simultaneous draws do not simply add, and getting the loss wrong either starves the far end or wastes capital.

常见问题FAQ
氧气系统为什么禁油？Why is oxygen service oil-free?
油脂在纯氧中极易燃烧，甚至爆燃。装配、试压与维护都必须用禁油工具与材料，并做脱脂处理。Grease burns violently in pure oxygen, even detonates. Assembly, testing and maintenance need oil-free tools and materials, with degreasing where required.
氮气会中毒吗？Is nitrogen toxic?
氮气本身无毒，但会置换空气造成缺氧窒息。封闭空间使用氮气必须通风、检测氧含量并设警示。Nitrogen is not toxic but displaces air and asphyxiates. Enclosed spaces need ventilation, oxygen measurement and warning signs.
汇流排和集装格怎么选？Manifold or bundle?
按换瓶频次与场地。汇流排适合小流量、空间紧张；集装格适合用量中等、换瓶集中管理。两者都可以配自动切换。By changeover frequency and space: manifolds suit low flow and tight rooms, bundles suit medium demand with consolidated changes. Both can be fitted with auto changeover.
CO₂ 管路为什么会堵？Why does CO2 piping plug?
节流后温度下降形成干冰。要控制减压方式、加伴热或加热器，避免在低压段出现固相。Throttling chills the gas into dry ice. Control the let-down, add tracing or a heater, and avoid solid formation in the low-pressure section.
成套设备能整体搬迁吗？Can a package be relocated?
撬装或集装形式可以，但搬迁后要重新做压力试验、气密与安全附件校验，不能直接复用原记录。Skid-mounted or bundled packages can be, but after moving they need fresh pressure, tightness and safety-device verification — the old records do not carry over.
