The 5 1/2” Drill Pipe (24.7 lb/ft, Grade S‑135) is one of the most dependable and widely used components in modern drill string assemblies. Built for demanding onshore and offshore drilling, this drill pipe delivers excellent performance in directional drilling, horizontal drilling, and high‑temperature/high‑pressure (HPHT) environments. The addition of the HLIDS 5 1/2 FH connection makes it a strong choice for heavy‑duty operations, deep wells, and complex drilling programs
:Advantages and Performance Features
Exceptional Strength and Durability
Manufactured from high‑tensile S‑135 steel, this drill pipe offers outstanding resistance to heavy loads and extreme downhole pressures. Its mechanical strength makes it ideal for challenging oil and gas drilling operations.
HLIDS Double‑Shoulder Connection
The HLIDS 5 1/2 FH connection features a robust double‑shoulder design that provides higher torque capacity and improved sealing. This makes it especially suitable for directional and horizontal drilling, where torque transfer and connection reliability are critical.
Compatible with Advanced Drilling Technologies
This drill pipe is fully compatible with Rotary Steerable Systems (RSS) and other advanced drilling tools used in HPHT and complex well environments. It ensures stable performance and reliable toolface control throughout the drilling process
Long Service Life with Enhanced Wear Protection
Surface hardening and hardbanding options significantly reduce wear caused by contact with the wellbore wall. These features extend the pipe’s operational life and help reduce maintenance and replacement costs.
