HKF-threaded tubing
Purpose
High-strength wear-resistant HKF thread is used on tubing for process operations in oil and gas wells with abnormal operating conditions. HKF threads have an elongated design and are characterized by improved strength characteristics.Field of application
NKF-threaded joints, unlike conventional triangular HKF threads as per GOST 633-80, have an elongated design, resulting in high strength characteristics, allowing the use of pipes with this thread type for process operations in wells, incl. hydraulic fracturing of formation.Advantages of the NKF-threaded joint
- The bearing capacity of HKF-threaded joint is 20% higher than conventional tubing as per GOST 633-80.
- HKF-threaded pipes are 15% cheaper than hardened upset-end pipes.
- The lifetime of HKF threads is 16 times higher than conventional threads.
- Thread misalignment is eliminat.
