Aluminum standard nose

It contributes to the descent of the casing bottom, protecting the bottom of the casing from damage.
Technical properties
  • integrally-machined from high-alloy aluminum
  • left-handed threading connection to the casing shoe ensures greater bond and fast drill-out
  • large diameter of main cementing port reduces pressure drops
  • shock-load resistant
  • available without cementing port
Shoes and couplings are usually used in the lower interval of the well and provide a reduction in the load on the mast when running the casing through zones with ledges and collapses in the wellbore, as well as landing sites for the lower and upper cementing plug. The back pressure valve prevents fluid from flowing into the casing when the pipe is lowered into the well and prevents cement entry back into the casing after injection, while allowing circulation through the casing.
