Drill Collar-Slick en Spiral Downhole Pipe
De drill kraach is makke fan AISI 4145H of finish rolling strukturele alloy stiel, ferwurke as per API SPEC 7 standert.
Yn it heule produksjeproses fan drillkraach binne de testgegevens fan 'e prestaasjestest fan elk item, fan wurkblêd, waarmtebehanneling oant ferbinende thread en oare fabrikaazjeproses, traceable.
Deteksje fan drillkragen is folslein neffens API-standert.
Alle triedden ûndergeane phosphatization of koper plating behanneling sa as te fergrutsjen harren corrosie ferset en mije tool threads 'thread gluing fenomeen.
Us bedriuw kin slips en liftgroeven op 'e boarkraach ferwurkje neffens de easken fan 'e brûker.
