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.
Welding should be done by qualified personnel as outlined in Section IX of the ASME Boiler Code. Weld filler material should be the same as the base material.
