Pipa bor beurat beurat
Pipa bor beurat beurat integral nyaéta zona transisi antara kerah bor sareng pipa bor.Éta henteu ngan ukur tiasa ngirangan formasi setrés dina sambungan kerah bor sareng pipa bor, tapi ogé ngirangan ngagem dina OD.
Pipa bor beurat beurat integral dijieun tina hiji sapotong AISI 4145H bar padet, pinuh panas diperlakukeun, sadaya sipat fisik akur jeung API spec7 édisi panganyarna.
Banding keras tahan tahan HWDP mangrupikeun standar dina sambungan sambungan alat sareng kesel sentral.Jinis hard banding kalebet Arnco 100XT sareng 100XT.Kabéh threads anu phosphated, copperized atawa tiis digawé.Sadaya sambungan dilengkepan pelindung benang baja anu dipencet.Sadaya iklan didamel nganggo mesin bubut CNC - benang ganda sareng benang khusus.
