Drill pipe darts separate the cement column in the drill string and activate/release the wiper plugs. For the duo wiper plug system, one drill pipe dart is pumped before and behind the cement column. With the single wiper plug, only the drill pipe dart behind the cement column is used. Our sponge-ball drill pipe dart provides outstanding sealing properties in the drill pipe combined with optimal cleaning. Different sizes are available.
- Available for all drill pipe sizes
- One-size string or combined string
- Available with lock feature
