Hilong USA and Hilong Canada are pleased to introduce HLNST, our next generation double shoulder tool joint connection designed to deliver superior strength, improved efficiency, and long-term cost savings for today’s drilling operations. Developed from the proven HLST and HLIST series, HLNST provides operators with a high-performance connection built for challenging environments.
Why Choose HLNST?
HLNST brings together the best of durability, operational efficiency, and user-friendly design. Its performance benefits make it a strong choice for drillers looking to improve reliability and productivity in increasingly complex drilling conditions.
Exceptional Performance
Superior Torque Strength
Under the same operating conditions, HLNST matches or exceeds the torsional strength of HLST and HLIST. This added strength helps support streamlined tool joint designs and contributes to improved hydraulic performance during demanding drilling operations.
Enhanced Fatigue Resistance
HLNST offers improved fatigue resistance compared to HLST and HLIST connections. This enhancement supports longer drill pipe life and more dependable performance in harsh drilling environments.
Operational Efficiency
Quick Makeup and Breakout
HLNST requires fewer turns during both makeup and breakout. This helps save rig time, reduce thread wear, and simplify operations on the drill floor.
User-Friendly Design
An optimised guide side angle makes HLNST easier to handle and more efficient to makeup. This design improvement supports smoother day-to-day use in the field.
Cost-Effective Durability
Lower Maintenance Costs
An improved tooth profile contributes to easier maintenance, helping operators reduce overall upkeep costs and extend equipment life.
Fewer Repairs
HLNST has wider inspection tolerances while still maintaining performance. This means the pipe does not need to be repaired as often, which helps reduce downtime and operational expenses.
Extended Recut Life
With minimal material loss during recuts and a shorter tong gripping distance, HLNST allows for more recuts before the drill string needs to be replaced. This supports long-term cost savings and greater drill string longevity.
Versatile Configurations for Diverse Drilling Needs
HLNST is available in sizes ranging from 3½ inches to 6⅝ inches, with MUT values calculated at SMYS 130ksi. This range allows operators to choose the right configuration for a variety of drilling applications.
