VAN RUTH® CEMENTING & WEDGING PLUG (CW PLUG)
The VAN RUTH® CW PLUG (CW) is a highly effective bridge plug for spot cementing sections of drill holes or wedging in off bottom situations for branch hole operations.
The CW PLUG is placed by pumping through the drill string and locks in the drill hole upon leaving the rods. The cup on top provides a seal on the drill hole.
**Do not lower the rod string back down on the plug in either situation as this will damage the plug and/or become stuck in the rods and pulled up hole**
A vented hoisting plug should be used while withdrawing the rod string with the rods being withdrawn at moderate speeds only. Suction above the CW PLUG may have a tendency to pull it up the hole. This effect is further increased if grease or soft sections in the hole seal against the rod string.
For the same application but where the hole is making water please see the CWBP.
Construction: Drillable aluminium and rubber, Also available in non spark material illustrated above in black. Material Data Safety Sheets (MSDS) available upon request.
