- Hydraulic extrusion for large NPS; heat treatment per WPB
- Reinforced branch when required by stress analysis
- Beveled butt-weld ends for field construction
Inspection & release
- Run and branch center-to-end inspection
- Wall thickness at crotch region when ITP requires
- PMI and weld NDE per project
- Third-party inspection and 3.1 MTC
Engineering FAQ
Catalog listings match the line schedule for procurement. Reinforced tees may be required for high-pressure designs—follow the piping spec.
Yes. Provide run NPS, branch NPS and schedule on the MTO for B16.9 reducing dimensions.
Center-to-end (C) for run and branch of straight equal tees per ASME B16.9, in millimeters.
Documentation can include EN 10204 3.1, ITP sign-off and third-party inspection for EPC contracts.
