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· Hilong proprietary high-strength grades provide superior tensile and torsional strength compared to API grades; thus be able to use for drilling deeper and further.
·The special material and unique heat treatment process facilitate to meet both yield strength and toughness requirements, it also has better fracture toughness and fatigue resistance;
·The thin-walled, light-weight and improved size design are conducive to improving the hydralulic efficiency of drilling, and is suitable for extended reach well and super-deep well.
Product Specification(a)Size Range: Including all API size from 2 3/8" to 6 5/8" inches；
(b)Steel Grade: HLDT-SH®Z140, HLDT-SH®V150 and HLDT-SH®U165.
