Product Overview

API 5DP E75 drill pipe is medium‑strength alloy drill pipe for shallow and light‑load drilling operations. Produced in compliance with API Spec 5DP standard, it adopts inertia friction welding process to connect pipe body with upset thickened tool joints, delivering stable torque transferring, reliable tensile performance for underground rotary drilling.

E75 grade features balanced mechanical property, lower material cost compared with X95/G105/S135 grades. Supports full NC thread series NC26, NC31, NC38, NC40, standard R2 length 9.14 meter, compatible with most mainstream small‑medium drilling rigs.

Main application covers water well drilling, shallow geological survey, HDD horizontal directional drilling, shallow coal‑bed methane exploration.
