制造能力
- Forged or plate slip-on flanges per ASME B16.5 Class 150
- Bore matches listed NPS/SCH for fillet weld to pipe
- RF 1/16" facing standard; FF or RTJ on inquiry
- Cost-effective alternative to weld neck for lower cyclic loads
检验与放行
- Flange OD, bore and hub fillet prep inspection
- PMI per heat; dimensional report vs B16.5
- MT on weld prep surfaces when required
- EN 10204 3.1 certificates for export
工程常见问题
The pipe passes through the bore and is fillet welded at hub and inside. Weld neck uses a butt weld to the pipe end; choose per line class and stress.
Flange OD and bolt circle for Class 150 RF are the same family per B16.5; hub geometry and weight differ by type.
Yes. Specify NPS and schedule on the inquiry for correct bore ID.
Yes on inquiry. See Class 300 WN chart or request SO 300# on the MTO.
