Company Profile

High Strength HDD Drill Pipe with G105 and S135 Steel Grades for 724 MPa Yield Strength

The trenchless drilling pipe is the core component of horizontal directional drilling construction. It is mainly used for laying underground pipelines in cities, as well as for oil and gas pipeline crossings and other non-digging projects. It has characteristics such as high strength and resistance to fatigue.

Detailed Technical Specifications of Trenchless Drill Rod

Dimensions and Specifications‌

Metric outer diameter ranging from 50 to 168.28mm (such as the commonly used 89mm model for municipal projects), wall thickness ranging from 6.0 to 12.7mm, and single rod length up to 12 meters.‌‌

Mechanical Properties‌

The most common steel grades are G105 (yield strength 724 MPa) and S135 (931 MPa), with the S135 grade having the highest tensile strength of up to 1138 MPa.‌‌

Torque Capacity‌

The maximum torque of the 89mm drill rod is 24 kN·m, and the commonly used torque range for municipal projects is 6 - 24 kN·m.‌

Product Purchase and Usage Guide

Construction Specifications

For depths exceeding 756 meters, thickened drill pipes must be used.‌
If the surface scratch is greater than 1mm, it should be replaced immediately.‌
The curvature radius of the construction hole must be smaller than the minimum curvature radius of the drill pipe.‌
