API 7k Casing Manual Tong

The API 7k Casing Manual Tong is a manual-operated gripping tool used to make up and break out casing connections during drilling and completion operations. Dongying Lake Petroleum Technology co.,ltd manufactures this unit to API 7k standards, the American Petroleum Institute specification for drilling and well servicing equipment. The tong features an alloy steel body with a mechanical gripping mechanism designed to handle casing pipes across standard API casing sizes. The supplier sources from Dongying City, a recognised oilfield equipment manufacturing cluster in Shandong Province, China.

The body construction uses alloy steel selected for tensile strength and wear resistance under cyclical loading typical of make-and-break operations. The gripping mechanism employs dies or jaws that engage the casing surface, with torque transmission through a manual lever or chain drive system depending on the model variant. Standard industry practice for manual tongs of this class includes heat-treated alloy steel forgings for critical load-bearing components, with hardness values typically in the 285-341 BHN range for die surfaces. The lightweight designation in the supplier description refers to relative portability compared to hydraulic power tongs, though exact weight varies with casing size capacity.

Primary buyers include drilling contractors, well service companies, and rental firms operating in onshore oil and gas fields. The tool suits applications where power tongs are unavailable or where manual operation is preferred for specific casing sizes. Contractors typically use this equipment during casing running, remedial workovers, and plug-and-abandonment operations. Buyers should confirm with Dongying Lake Petroleum Technology co.,ltd the exact casing size range, torque rating, and whether the unit includes safety features such as a positive locking latch or torque gauge provision. Shipping terms and certification scope need direct verification with the supplier.

Dongying Lake Petroleum Technology co.,ltd operates from 15 Floor, Huatai Center in Dongying City, Shandong Province, with postal code 257000. Dongying is a known concentration for petroleum equipment manufacturing in China, with supply chain density in forgings, machining, and oilfield tooling. The supplier holds a harbor trust tier on the platform. The response rate displays as 0.00 with zero average response hours, which indicates either a new listing or unrecorded response data, buyers should test responsiveness directly before relying on timing assumptions.

The company profile as listed does not state founding year, employee count, revenue, specific factory details, or named client relationships. No ISO or API certificates are confirmed in the available data beyond the API 7k product description claim. Buyers should request current certificate copies, scope of accreditation, and quality system documentation directly. The address places the company in a commercial office building rather than a manufacturing campus, so production facility location and capability warrant clarification.
