Heavy Weight Drill Pipe
Yntegraal swier gewicht drill piip is de oergong sône tusken drill kraach en drill piip.It kin net allinnich ferminderjen stress-formaasje yn de ferbining fan drill kraach en drill piip, mar ek ferminderjen de wear op OD.
Yntegraal swier gewicht drill piip wurdt makke fan ien stik AISI 4145H bêst bar, folslein waarmte behannele, alle fysike eigenskippen oerien mei API spec7 lêste edysje.
HWDP syn wear ferset hurde banding is standert op ark gewrichten ferbinings en sintrale upset.De soarten hurde banding omfetsje Arnco 100XT en 100XT.Alle triedden binne phosphated, koperisearre of kâld bewurke.Alle ferbinings binne foarsjoen fan yndrukt stielen tried protectors.Alle platen wurde ferwurke mei CNC-draaibanken - dûbele skuorren en spesjale triedden.
