Weld-on Casing Adapters
Akkerman’s Weld-On Casing Adapters are often imitated, but never duplicated. These adapters are designed to connect pilot tubes that have been installed on line and grade to steel casing that will be installed by either auger boring or pipe ramming. Designed with high grade steels and a specific weld process to match, these adapters can be custom built to suit your specific diameters.
FEATURES:
Weld-On Reaming Head (WORH)
- Designed for guided auger boring applications in displaceable ground conditions.
- Diameters up to 36‑in can connect directly to the installed pilot tube string using standard Akkerman connections.
- Multi‑stage WORHs recommended for diameters larger than 36‑in; typical stage is ½ the final casing diameter for casings up to 72‑in.
- May be used with a pneumatic pipe ram when obstacles are encountered.
- Allows the contractor to lag the cutter behind the adapter for natural plugging in unstable ground or to remove augers for obstacle removal.
- Standard steel casing bore diameters stocked; custom diameters available.
Guided Ramming Head
- Designed for guiding steel casing installations using pneumatic pipe hammers.
- Optimized to allow dynamic soil movement along casing walls while resisting fatigue and eliminating side loading to maintain alignment.
- An additional 10‑ft hex core rod is recommended when connecting ramming heads directly behind pilot tubes to absorb shock loads.
- Standard steel casing bore diameters stocked; custom diameters available.
