Manufacturing & quality assurance
Yanshan Hengzhenyuan Pipeline — integrated forming, heat treatment, machining and NDT for export utility and EPC programs.
Production capability
- Equal straight tees per ASME B16.9; seamless or welded construction
- Hydraulic extrusion and hot-forming for large NPS; heat treatment per grade
- Uniform wall at branch intersection; reinforcement per design when required
- Beveled butt-weld ends per ASME B16.25 for field fit-up
Inspection & release
- Ferrite PMI on each heat; dimensional check of run and branch center-to-end
- Surface NDE (MT/PT) on welds; volumetric UT/RT per project ITP
- Mechanical tests tied to heat number; hardness on welds when specified
- Independent inspection agency release and 3.1 certificates for export lots
Engineering FAQ
For standard equal tees, the catalog wall listed matches the matching pipe schedule on the run and branch for procurement purposes. Reinforced or extruded tees for high-pressure designs may require additional wall per the piping stress analysis.
Yes. Reducing tees use branch and run NPS from the line list. Dimensions follow ASME B16.9 reducing tables; quote with both run and branch sizes.
Values are center-to-end (C) for the run and branch of a straight equal tee per ASME B16.9, in millimeters, for layout and spool length estimates.
Documentation is tailored to the contract: EN 10204 3.1, ITP sign-off, and third-party inspection are routine for EU and Middle East projects. Declare the required compliance scheme on inquiry.
