Alaabta
API 7-1 qodista Roller Reamer oo leh Nooca B & Nooca F & Nooca T
Codsiga Alaabta
Roller Reamer waxaa loogu talagalay hawlgal dib-u-dejineed oo kala duwan laakiin gaar ahaan ujeedooyinka xasilinta marka la qodayo qaabab aad u xoqan.Waxay ku haboonaan doontaa cabbirka godadka ee u dhexeeya 4 5/8 ilaa 26inch. Intaa waxaa dheer, jidh kasta by hagaajinta fudud ee blocks iyo xulashada saxda ah ee gooyayaasha, waxay ku haboonaan doontaa cabbirro ballaaran oo godad ah.
Nooca alaabta
Saddex nooc oo kala duwan (T, F iyo B) ee gooyayaasha ayaa la bixiyaa:
Nooca T: Milicsan, lagu farsameeyay ilko fiiqan oo weji adag leh si ay u samaysmaan jilicsan.
Nooca F: mild, lagu farsameeyay ilko fidsan weji adag, oo loogu talagalay qaabab adag oo dhexdhexaad ah.
Nooca B: Waxaa lagu qalabeeyay badhamada carbide tungsten oo la riixay, oo loogu talagalay qaabab adag.
