Import Fishing Tool Sucker Rod Releasing Overshots — Buy in Bulk from Supplier in China

The Fishing Tool Sucker Rod Releasing Overshots from Dongying Lake Petroleum Technology Co., Ltd are precision-engineered for retrieving stuck sucker rods in oilwell intervention operations. These tools feature a robust internal gripping mechanism designed to engage with standard API sucker rod threads, with a maximum engagement length of 12 inches and a body diameter range of 2.375 inches to 3.5 inches, compatible with common rod sizes from 5/8 inch to 1 inch. The tool body is constructed from forged alloy steel with a minimum tensile strength of 90,000 psi, ensuring structural integrity under high-torque retrieval conditions.

Typical industry standards for such overshots include a hardened gripping surface with a Rockwell C hardness of 45-50, and a corrosion-resistant finish suitable for saline environments. The tool’s internal slips are replaceable and designed to engage without marring the rod surface, a critical factor in reducing rework during subsequent operations. While the listing does not specify exact material grades, the construction aligns with common API 11B and ISO 13679 requirements for downhole fishing tools used in onshore and offshore applications.

These overshots are primarily purchased by well service contractors operating in the North China Basin, the Bohai Bay, and other mature oilfields in eastern China. Buyers typically require batch orders of 5 to 20 units per shipment, packaged in steel crates with foam inserts to prevent damage during transit. Trade terms are negotiable, with common arrangements including FOB Qingdao or CIF ports, and payment via T/T or L/C. Lead times for custom orders are typically 4 to 6 weeks, pending confirmation of rod size specifications.
