Dth Drill Rod/pipe With 4 Wrench Flat
The product is a DTH drill pipe equipped with a four‑point flat wrench interface, designed for rapid tool changes in rock‑drilling rigs. Linqing City Ruilong Drill Co., Ltd. manufactures the pipe from high‑strength carbon steel and offers a heat‑treated surface to resist wear during high‑pressure operations. The pipe dimensions follow standard industry sizes, facilitating compatibility with a range of DTH hammers.
Typical specifications include a 89 mm (3.5 in) diameter, 8 mm wall thickness and a standard 3 m length, which align with common underground long‑hole and tunnel drilling requirements. The flat wrench end provides a secure connection for quick‑change hammers, a feature frequently requested by contractors operating in variable geological conditions. Ruilong’s catalogue also lists high‑pressure, medium‑pressure and low‑pressure variants, allowing buyers to select the appropriate pipe for their hydraulic system.
Customers such as mining contractors, underground tunnelling firms and geothermal drillers source this pipe for efficient hole‑making. Trade terms require confirmation of packaging - typically steel‑framed pallets with wooden shims - and verification of Incoterms, which are usually negotiated as FOB in the nearest Chinese port. Prospective importers should request detailed technical drawings and confirm any required certifications before finalising the purchase.

Sourcing Dth Drill Rod/pipe With 4 Wrench Flat from Linqing City Ruilong Drill Co., Ltd. - China Import Guide
Prior to ordering, confirm the exact steel grade, diameter, wall thickness and the wrench‑flat end dimensions. Request the material test report, tensile test certificate and any relevant welding or heat‑treatment documentation to ensure the pipe meets project requirements. Clarify any minimum order quantity directly with the supplier as it is not listed publicly.
Logistics are usually arranged from a Chinese port such as Qingdao or Tianjin. Typical lead times range from four to six weeks, but the supplier should provide a specific schedule for each order. Buyers commonly negotiate FOB terms and a payment structure of 30 % T/T deposit with the balance payable against shipping documents.
For quality assurance, arrange a third‑party inspection covering dimensional checks, hardness testing and visual weld examination. Insist on a certificate of conformity and a full set of test reports before cargo release. Proper documentation will facilitate customs clearance and help guarantee performance on site.
