Seamless
API 5DP Drill Pipe & Components

API 5DP seamless drill pipe in E75, X95, G105, and S135 grades — with upset tool joints for rotary drilling in onshore and offshore operations.

API 5DP drill pipe

OVERVIEW

The rotating backbone of every well.

Global Seamless manufactures API 5DP seamless drill pipe with friction-welded tool joints for rotary drilling operations. Every joint is produced to API specification with full mechanical testing, inspection, and dimensional certification.

Our drill pipe program covers conventional and directional drilling — from standard E75 for shallow wells to premium S135 for deep, extended-reach, and HPHT drilling where fatigue life and torsional strength are critical.

✓ API 5DP specification
✓ Grades: E75, X95, G105, S135
✓ IEU and EU upsets available
✓ Friction-welded tool joints
✓ Full EMI, UT, and dimensional inspection
