·High torsional strength
Under the same conditions, the torsional strength of HLST and HLIST can be reached or exceeded. This allows for use of streamlined tool joints and improved hydraulic performance.
·Better Fatigue Resistance
·Faster Makeup and breakout
HLNST has significantly fewer turns from stab to makeup and breakout than comparable HLST or HLIST connections. This saves time and reduces the amount of wear on threads.
·Easier to Makeup
(a)Reduced Repair Frequency
Repairs are expensive and time consuming. The field inspection tolerances for HLNSThave been widened without compromising performance, so you do not have to send the pipe in for repairs as often. This reduces downtime and saves you money;
(b) Less Recut Loss
