This document details Swagelok sample cylinders, rupture disc units, and outage tubes with specifications for sizes, materials, pressure ratings, and…
The document provides technical data for Swagelok double-ended and single-ended sample cylinders. These vessels are constructed from stainless steel (304L, 316L) or Alloy 400 and are available in various volumes ranging from 150 cm³ to 3785 cm³ (1 gallon). They meet DOT and TC specifications with working pressures up to 5000 psig.
| Sizes | 10 to 3785 cm³ (1 gal) |
|---|---|
| Working pressures | up to 5000 psig (344 bar) |
| Materials | 304L and 316L stainless steel and alloy 400 |
| Testing method | Hydrostatically tested to at least 5/3 the working pressure |
Ratings up to 100°F (37°C) are determined by DOT code, while ratings limited to 300°F (148°C) max require PTFE internal coating.
The minimum burst pressure must be at least 40% higher than the cylinder filling pressure.
