Import Hdd Drill Pipes — Buy in wholesale FOB from Supplier in China

The Hdd Drill Pipes offered by Dongying Lake Petroleum Technology co.,ltd are integral drill rods intended for small‑hole drilling applications. These rods support borehole diameters from 29 mm to 41 mm, with standard hexagonal cross‑sections and chisel or cross tips. Typical rod diameters of 19 mm and 22 mm are also supplied, matching common industry sizes. Lengths range from 600 mm up to 9 600 mm, allowing selection of appropriate sections for various drilling depths.

The product line includes tapered drill rods designated H22 and H25, with body lengths between 400 mm and 8 000 mm and tip taper angles of 4.8°, 7° or 12°, which are standard options for precision drilling. Shank lengths are offered in 108 mm or 159 mm sizes, and the shank flushing holes are Ø7.5 mm to Ø8.5 mm, facilitating effective cut‑tings removal. Materials are described as high‑grade steel combined with tungsten carbide inserts, a typical composition that provides wear resistance and strength. Weight is reported to be about 45 % lighter than conventional drill pipes, a common advantage of modern integral rods.

The supplier states flexible ordering options, protective packaging and the ability to ship under FOB or CIF terms, though exact lead times and payment conditions must be confirmed.
