Manufacturing & quality assurance
Yanshan Hengzhenyuan Pipeline — integrated forming, heat treatment, machining and NDT for export utility and EPC programs.
Production capability
- WP316L elbows for chloride and marine service per ASME B16.9
- Solution annealed after forming; low carbon for weld integrity
- Pickling passivation standard; electropolish on inquiry
- Beveled butt-weld ends per project weld procedure
Inspection & release
- PMI confirming 316L chemistry
- Dimensional inspection vs B16.9
- Ferrite or corrosion testing when ITP requires
- Mill certificates 3.1 with heat analysis
Engineering FAQ
316L offers better resistance to pitting and crevice corrosion in chlorides and many chemical services. Follow the project material specification.
WP316L is capped at 0.030 % carbon. Standard WP316 may be used where the spec allows higher carbon.
Generally avoid mixing grades in corrosive service without engineering approval. Weld procedures must address dissimilar metals if permitted.
Yes. Other B16.9 fittings in A403 grades can be quoted on the same MTO.
