Seamless Carbon Steel Pipes in Deepwater Drilling Applications

Date:2025-03-15

Deepwater and subsea oil exploration require seamless pipes with high tensile strength and corrosion resistance under extreme pressures.

High-Collapse (HC) Pipes: API 5L X70/X80 pipes resist external hydrostatic pressure at depths of 3,000+ meters.
Sour Service Resistance: HIC-tested pipes prevent hydrogen-induced cracking in H₂S-rich environments.
Residual Stress Elimination: Quench & temper (Q&T) processing enhances fatigue resistance in dynamically loaded riser systems.
