Procedure for installing Swagelok tube fittings in sizes over 1 inch or 25 mm.
This document specifies guidelines used by Swagelok® Company and its suppliers to ensure compliance with product cleanliness requirements as stated in ASTM G93 Level C. Application of the document is limited to wetted system components. This document must be used in conjunction with product catalogs, technical bulletins, and reports.
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.
