Linqing City Ruilong Drill Co., Ltd. manufactures DTH drill pipes used in mining, water‑well drilling, geothermal and oil‑field rock drilling, fabricating them from low carbon steel and joining the sections by friction welding to create a continuous pipe‑body. The production process includes cyclic extrusion‑compression to improve structural reliability, and the company ships from Linqing, Shandong, China.
In the DTH drilling market, a common pipe size is an outer diameter of 76 mm with a wall thickness of 6 mm, length of 3 m and a weight of about 12 kg per metre. Typical tensile strength for low carbon steel in this application ranges from 400 to 550 MPa, with a yield strength around 250 MPa. Standard pressure rating is 10 MPa and the pipes are usually supplied with a 3‑inch male and 2.5‑inch female threaded connection. International standards such as ISO 22457 define dimensional tolerances of ±0.2 mm for diameter and ±0.1 mm for wall thickness.
The pipes are bought by drilling contractors, mineral‑exploration firms and water‑resource companies that need a robust conduit for hammer‑driven drilling. Importers typically request a product data sheet and a mill test report before placing an order. Because the listing does not disclose minimum order quantity, payment terms or lead time, buyers should confirm those details directly with the supplier and agree on an Incoterm such as FOB Qingdao. Products are usually packed in wooden crates with individual pipe protection.

Before placing an order, ask for a mill test report, a material certification and the friction‑welding procedure documentation. These documents confirm that the low carbon steel meets the typical tensile and yield strengths described and that the welding quality is consistent with industry practice.
Shipping is normally arranged from ports in Shandong province, such as Qingdao. Buyers should agree on an Incoterm - for example FOB Qingdao - and verify the expected lead time with the supplier, as the listing does not state a specific schedule. Payment terms are also not disclosed, so negotiate clear terms before finalising the contract.
Arrange a third‑party inspection to check dimensions, wall thickness and any visible welding defects. Request a final inspection report and a certificate of conformity to ISO 22457, which will help ensure the pipes meet the required standards for your drilling projects.
