V. Cementing Tools - a. Heavyweight Cement Manifold – Single Dart
Allamon Tool Company’s Heavyweight Cement Manifold is used for cementing operations of sub-sea casing long strings. Having been pull tested to the ultra-high tensile load rating of 2.7 million pounds, it is the perfect choice for operators running large heavy casing strings. A swivel can be incorporated for liner applications. The by-pass flow area during displacement is the largest in its class, therefore reducing risk of washing-out internal parts due to the extremely high flow rates typically used on cementing large casing strings in the deepwaters of the Gulf of Mexico.
Features/Benefits
  • Simple function for ease of use on location
  • SSwivel option with bearing assembly for working tool string
  • Various dart tube sizes that match DP size to increase dart reliability
