Details still need confirmationRequired before engineering approval / quotation
- Service fluid
- Design pressure and units
- Design temperature and units
- Verified flange drilling and bolt-hole count
- Flange OD, PCD, bore/hub and thickness from the approved drawing
- Gasket material, thickness, dimensions and service suitability
- Bolting grade, diameter, length and tightening procedure
- Applicable piping code, material specifications and pressure-temperature suitability
- Weld-neck bore and end-wall match to the pipe
Matching nominal labels is not a compatibility approval. Design pressure, temperature, material group, facing, drilling, gasket and bolting must be checked together.
