PRODUCT / SUPPLY OPTIONS
Flanges
Flange enquiries for piping and equipment connections. Grade, connection standard, flange type and pressure class are assessed together.
Dimensions and supply options
| Product | Dimensions | Specification / delivery |
|---|---|---|
| Flanges | DN / NPS · PN / Class · type · facing | Per quotation |
Availability depends on grade and dimensions. Tolerance, surface, delivery condition and certificate requirements must be confirmed in the quotation.
Diameter alone does not define a flange
Bolt circle, hole count, facing and connection standard determine fit. Weld-neck, slip-on and threaded flanges are different products. Specify material and dimensional standards separately; conformity to one does not establish the other.
Pressure class is not operating pressure
PN or Class cannot be read as one allowable pressure independent of material and temperature. Assess medium and design conditions using the applicable standard. Send service conditions, tests and documentation with flange type, size, facing and grade.
Choose the grade with the section
The same section can serve different applications in different grades. Tell us about the operating environment, machining needs and any material specification.
Frequently asked questions
How can I specify compatibility with my connection?+
Share material and dimensional standards, nominal size, end or facing type, pressure class and any existing product markings or drawing. Compatibility is assessed against the complete request.
Which certificate should I request?+
If required by your project, specify an EN 10204 3.1 inspection certificate and any additional testing in your request. Document availability is confirmed before supply.
