Import Drill Pipe — Buy in Bulk from Supplier in China

Tianhe Oil Group Huifeng Petroleum Equipment Co., Ltd manufactures drill pipes designed for oil, gas and mining drilling operations. The pipes are produced from high‑strength carbon steel and feature a high tensile strength suitable for demanding down‑hole conditions. A range of lengths and outer diameters is available, allowing customers to match the pipe to specific well designs. Each pipe receives an internal corrosion‑resistant coating to extend service life in aggressive environments.

In the oilfield sector the typical grade for such pipes is API J55 or higher, delivering a minimum tensile strength of about 470 MPa. Standard outer diameters run from 2.5 in (63 mm) to 6.5 in (165 mm) with wall thicknesses between 0.3 in (7.6 mm) and 0.8 in (20 mm). Dimensional tolerance is usually ±0.2 mm on the outer diameter and ±0.1 mm on wall thickness, ensuring tight fit with API‑rated connections. The pipes are machined to API 5CT thread specifications and inspected under ISO‑based quality control procedures.

These drill pipes are typically purchased by drilling contractors, well service companies and mining operators who require reliable down‑hole components. Tianhe offers flexible minimum order quantities and accepts payment by L/C or T/T, with shipping arranged from major Chinese ports. All products are certified to API and ISO standards, and the supplier can provide mill test reports on request.
