Import Drill Pipe — Buy in Bulk from Supplier in China

This drill pipe is manufactured by Yichang Wuhuan Rock Drilling Tools Co., Ltd for use in oil, gas, and mineral exploration operations. The product is built to meet API 5D standards, with typical wall thicknesses ranging from 8.5 mm to 15.5 mm depending on grade and diameter. Each pipe undergoes dimensional checks and non-destructive testing to ensure structural integrity under high torque and axial loads. The supplier does not specify exact grades but confirms compatibility with standard drilling rig connections and threaded end finishes.

The material is typically carbon steel with added manganese and chromium for enhanced tensile strength and corrosion resistance. Standard heat treatment processes are applied to achieve consistent mechanical properties across batches. Surface finishes are generally black oxide or bare steel, with no coating specified. Typical internal and external upset designs are used to reinforce threaded joints, reducing the risk of fatigue failure during repeated make-up cycles.

These drill pipes are primarily purchased by drilling contractors in Asia, the Middle East, and Latin America for directional and vertical boreholes in hard rock formations. Buyers commonly require lengths in Range 2 or Range 3, with standard lengths of 9.1 meters and 13.7 meters respectively. Packaging is usually in steel cradles with protective end caps. Trade terms are typically FOB Yichang Port or CIF destination port, with minimum order quantities negotiable based on project scale.

Yichang Wuhuan Rock Drilling Tools Co., Ltd operates from Wujiagang Industrial Zone in Yichang, Hubei Province, China. The company is registered as an imported supplier with harbor-level trust verification, indicating active export compliance and logistics readiness. The listing does not provide details on factory size, workforce, years in operation, or client references, and no certifications are stated beyond implied API compliance.

The supplier specializes in drilling tools including drill pipes, collars, and stabilizers, with production focused on mid-tier oilfield equipment. There is no evidence of in-house R&D, proprietary coatings, or ISO certification claims. Response rate and average response time are not tracked, suggesting limited buyer support infrastructure. Buyers should verify product consistency through sample requests and third-party inspection before bulk orders.
