Hilong Double Shoulder Connection

Product Introduction

HLIDS® is an API compatible high torque double shoulder connection developed by Hilong.
HLMT® is a double shoulder connection designed and developed refer to API connection and customer's requirement 
on site.
HLIDS® and HLMT® have features as follows:
• The same standard thread profile as API;
• Double shouldered design;
• Smooth transmission on inside diameter;

Product Advantage

·Higher Torque: by using HLIDS® and HLMT® connections with current API ODs and IDs will result in 20%~50% of torque capacity higher than API.
· While maintaining required torsional strength, it can:
- minimize the tool joint OD;
- maximize the ID;
·High fatigue resistance, thus prolong the pipe service life.
·Improving hydralic efficiency and reduce washout.
