Hilong Super High-Strength Drill Pipe

Product Introduction 

Hilong super high-strength steel grades HLDT-SH®Z140, HLDT-SH®V150 and HLDT-SH®U165 are proprietary products which designed specifically for deep and ultra-deep wells, extended reach drilling (ERD) wells, deep offshore and other critical drilling applications. With a special chemistry composition and carefully designed heat treatment process, HLDT-SH®Z140, HLDT-SH®V150 and HLDT-SH®U165 grades have realized high strength, high toughness and improved fatigue resistance.

Product Advantage
