Hilong - Model HLIDS & HLMT Series -Double Shoulder Connection
HLIDS® is an API-compatible high-torque double-shoulder connection developed by Hilong. HLMT® is a double-shoulder connection designed and developed for specific API connections and the customer`s requirement on-site.
- The same standard thread profile as API
- Double-shouldered design
- Smooth transmission on inside diameter
- Higher Torque: by using HLIDS® and HLMT® connections with current API ODs and IDs will result in 20% - 50% higher torque capacity than API.
- While maintaining required torsional strength, it can:
- minimize the tool joint OD
- maximize the ID
- High fatigue resistance, thus prolonging the pipe service life
- Improved hydraulic efficiency and washout reduction
HLIDS® series includes HLIDS®23, HLIDS®26, HLIDS®31,HLIDS®38, HLIDS®40, HLIDS®46, HLIDS®50, HLIDS®5
1/2FH and HLIDS®6 5/8FH etc. and can be applied to all API drill pipes with standard steel grades and specifications from 2 3/8 to 6 5/8 inches.
