Il往来帐他avy Weight forare il tubo (HWDP) offre un passaggio graduale dalla pesante,rigid drill collars to the more flexible drill pipe which helps to reduce
Offriamo peso in 3.1 / 2 ", 4", 5″ and 5.1/2″ consisting of hard banded tool joints and raised wear pads on central upsets to optimize wear
Offriamo due tipi di configurazioni HWDP; Standard HWDP e Spiral HWDP.
Standard HWDP
Prevents stress concentration and allows directional drilling with controlled torque and reduces differential pressure sticking.
Condivide molte delle stesse caratteristiche del HWDP standard.
Better reduction in differential sticking
Increased weight and stiffness
最大限度地减少磨损
Improves cutting circulation for better hole cleaning
Our preferred applications of hard banding for drill pipe tool joints and BHA components(HWDP, Collari Drill)are ARNCO 350XT or Duraband NC, entrambi NS-1 certificato; che non sono solo scopo di proteggere il tubo di trivellazione da indossare ma anche per proteggere la carcassa.We use a robotic welding system for
