Precision-forged Heptagonal Component
This advanced heptagonal forging represents a proprietary prototype co-developed with CNPC (China National Petroleum Corporation) for high-stakes petroleum industry applications. Manufactured from certified 31603 stainless steel via single-billet integral forging, the component achieves exceptional structural integrity and corrosion resistance. Our precision manufacturing protocol includes: rough machining, solution annealing, CNC precision finishing, deep-hole boring, and API-spec thread tapping. Engineered to withstand extreme downhole environments, it delivers unmatched dimensional accuracy (ISO 2768-m) and material homogeneity for critical sealing and load-bearing functions in next-generation drilling systems.
