Nominal pressure and ASME class are different rating systems. Confirm the pressure–temperature rating for the selected material and design.
End connections
Define the interface.
Shown configuration: Weld-end collars on the pictured side-entry butterfly configuration.
| Connection detail | Connection / selection requirement |
|---|---|
| Published connection | Butt weld or flanged |
| Connection standard | Not specified on this product page. Confirm the mating standard with the offer. |
| Weld selection | Specify pipe OD, wall thickness/schedule, material and weld preparation. SW and BW are different connections. |
| Flange selection | Specify nominal size, flange rating, facing, drilling and gasket. Do not infer these from the image alone. |
The illustration shows one configuration. Published connection alternatives are options for enquiry; their availability depends on size, rating, material and design. Installation dimensions come from the drawing, not the illustration.

Sizes and pressure ratings depend on construction, materials and configuration. Confirm the selected pressure-temperature rating with the quotation.
Published series limits are not a size-by-pressure availability matrix. Materials, temperature capability, leakage class, testing and certification are confirmed for the selected configuration.
Published ratings do not establish suitability for every listed medium. Oxygen cleaning, material compatibility, trapped-liquid relief and project approvals are specified for the selected assembly. Liquid-hydrogen and helium service require a separate temperature and material review.
