Import Drill Pipe — Buy in Bulk from Supplier in China

Dongying Goldenman Trading Co., Ltd. supplies drill pipe manufactured in China for heavy‑duty oil and gas operations. The product dimensions are specified as 127 mm outer diameter, 9.19 mm wall thickness and a length between 9 400 mm and 9 800 mm, conforming to the G105 grade. The pipe is built from high‑tensile steel designed to endure extreme pressures and abrasive environments. The supplier notes compatibility with standard drilling equipment and a robust API‑type thread.

In the drilling industry, a G105 grade corresponds to a minimum tensile strength of roughly 580 MPa, which is typical for medium‑strength pipe applications. Standard API 5CT specifications govern the thread profile and dimensional tolerances, ensuring interchangeability across rigs. Typical coatings for such pipe include chrome or epoxy to improve corrosion resistance in harsh wells. The length range of 9.4 m to 9.8 m aligns with common rig inventory practices, facilitating easier handling and pipe string assembly.

The pipe is targeted at drilling contractors, exploration companies and geological survey firms that require reliable drill strings. Trade benefits mentioned include flexible minimum order quantities, FOB and CIF shipping options, and payment via letter of credit or telegraphic transfer. While the listing references ISO certification, the specific standard numbers are not disclosed and should be confirmed directly. Prospective buyers are advised to obtain the latest material test reports to verify compliance with the G105 grade.
