氢气调压撬Hydrogen regulating skid
针对氢气低密度、易泄漏、易氢脆的特性做的三级减压撬，用于加氢站、掺氢与工业用氢。Three-stage skid built for hydrogen: low density, leak-prone, embrittling.
产品概述Product overview
氢气与天然气的差别，在撬上会变成三个具体问题：一是密度极低，同样压差下的流速和噪音都更极端；二是分子小，对阀杆填料与法兰密封的泄漏率要求高一个量级；三是高压下会渗入钢材造成氢脆，材料与焊接工艺必须另作评定。所以氢撬不套用天然气撬的图纸，而是按三级减压把压比进一步拆小，密封面改金属硬密封，出厂做氦检漏。Low density, small molecules and embrittlement force three-stage reduction, metal seals and helium leak testing.
氢用管道新国标发布后，选型还要对上管道材料、焊评与检验比例的要求。这类项目泰燃按介质、压力、纯度三项先定材料，再定阀组，最后定控制逻辑。New hydrogen piping standards add material, weld procedure and inspection requirements.
