The DC‑type Drill Collar Raiser supplied by Dongying Lake Petroleum Technology co.,ltd is manufactured in Dongying City, Shandong Province, China. It is intended to lift and hold drill collars in drilling rigs, providing a secure grip during well‑construction operations. The tool is fabricated from high‑tensile‑strength steel, delivering the strength required for heavy‑load applications. According to the listing, the design incorporates precision‑engineered components that reduce installation time and improve safety on site.
Typical steel grades used for drill‑collar raisers are ASTM A572 Grade 50 or equivalent, offering tensile strengths around 450 MPa (typical). Standard dimensions for the lifting eye range from 100 mm to 250 mm in diameter, and the overall weight of a 150 mm model is roughly 30 kg (typical). The device operates reliably within - 20 °C to +60 °C, matching the environmental conditions of most on‑shore drilling projects. Industry practice requires compliance with ISO 9001 and CE marking, which the supplier references in its description.
Primary customers are drilling contractors and oil‑field service companies that need reliable handling equipment for drill collars, as well as construction firms undertaking heavy‑lifting tasks. The supplier mentions flexible minimum order quantities and suggests that shipments can be arranged under standard Incoterms, but exact terms should be confirmed directly with the supplier. Prospective buyers are advised to request load‑test certificates and material test reports to verify tensile strength and safety factors. Clarify any certification details and packaging specifications before finalising the purchase.

Before committing to purchase, obtain the material certificate confirming the steel grade and tensile strength, and request the load‑test report that verifies the rated lifting capacity and safety factor. Verify the supplier’s ISO 9001 and CE certificates, and ask for a copy of the conformity declaration. Ensuring these documents are in place will reduce risk and support compliance with your internal quality standards.
When arranging logistics, agree on an Incoterm such as FOB Tianjin or CIF Shanghai, and confirm the estimated lead time for production and shipping. Discuss payment terms - for example a confirmed irrevocable letter of credit or a staged payment schedule - and ensure that customs documentation for heavy‑equipment imports is prepared. Align the delivery schedule with your project timeline to avoid downtime on the drilling site.
Implement a third‑party inspection prior to loading, focusing on dimensional checks, welding quality and the presence of the load‑test certificate. Request a final inspection report and a packing list that details the crate or pallet configuration. Maintaining thorough records of these quality checks and accompanying documentation will facilitate smooth customs clearance and provide traceability for future audits.
