Engineered for your application
A flanged stainless steel flame-arrester range with published dimensional data through DN 250.
Sizes and pressure ratings depend on construction, materials and configuration. Confirm the selected pressure-temperature rating with the quotation.
Technical data
The specification, in detail.
| Parameter | Technical specification |
|---|---|
| Size range | DN 25–250 |
| Pressure ratings | PN16 (1.6 MPa nominal) |
| End connections | Flanged |
| Published medium | IIC |
| Temperature range | -196 to +60°C |
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: Flanged protection device; this is not an isolation valve.
| Connection detail | Connection / selection requirement |
|---|---|
| Published connection | Flange（HG20592） |
| Referenced flange standard | HG 20592 (designation as published); edition, facing, drilling and pressure designation must be specified. |
| 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.
Materials
From body to seal.
| Component | Material / option |
|---|---|
| Body | 06Cr19Ni10 |
| Core | 06Cr19Ni10 |
| Gasket | 06Cr19Ni10+graphite |
Published material alternatives are configuration-dependent. H.F. denotes hard facing; the exact grade and material certificates are confirmed with the offer.
Selection notes
Defined around your application.
- Flange（HG20592）
Sizes and pressure ratings depend on construction, materials and configuration. Confirm the selected pressure-temperature rating with the quotation.
“IIC” is the medium classification stated in the reference. The required gas group, flame-arresting duty and certification must be specified for selection.
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.
