Swagelok® Specification SC-10 defines the cleaning, lubrication, assembly, and packaging requirements for standard Swagelok products and describes practices used to meet these requirements.
Valve sizing often is described by the nominal size of the end connections, but a more important measure is the flow that the valve can provide. And determining flow through a valve can be simple.
Pages 1-3. Features: installation in high-pressure applications and high safety-factor systems.
如果必要的话使用散热器以防止过度加热内部元 件; 如果轨道焊接操作较好的话，可以不需要散热 设备; 确保阀门处于打开位置以在焊接过程中维持持续 的吹扫气流; 使用高质量的吹扫气体以保持清洁 并减少焊接污染.
