Drag Block Springs
Drag Block Springs are specifically designed flat springs produced to meet certain oil & gas applications. They are utilized in the Drag Block assembly which runs in conjunction with down-hole tools that require rotation to set or unset, like mechanical packers or hangers. The Drag Block consists of hardened Blocks and Springs. The Springs apply an internal force to continually keep the Blocks in contact to the Casing wall. While placing the work string to the desired depth, the Drag Block will drag while running in the hole. Either Left-Hand rotation or Right-Hand rotation will create the spring-loaded Drag Blocks to engage against the casing wall it resides in.
