Lapho ama-ellipses (...) evela kuleli thebula, asikho isidingo, futhi ukuhlaziywa kwe-elementi akudingeki kunqunywe noma kubikwe. B Kuvumelekile uku-oda i-T2 ne-T12 enesulfure yokuqukethwe okungu-0.045 max. C Okunye, esikhundleni salobu buncane besilinganiso, impahla izoba nobulukhuni obuncane obungu-275 HV esimeni esiqinile, esichazwe njengokuthi ngemva kwe-austenitizing kanye nokupholisa ekamelweni lokushisa kodwa ngaphambi kokufudumeza. Ukuhlolwa kokuqina kufanele kwenziwe maphakathi nobukhulu bomkhiqizo. Imvamisa yokuhlolwa kokuqina kuzoba amasampula amabili omkhiqizo endaweni ngayinye yokwelapha ukushisa futhi imiphumela yokuhlola ubulukhuni izobikwa embikweni wokuhlolwa kokubalulekile.

Isidingo Sokuhlola
Ukuhlolwa kwe-Hydraustatic:
Ipayipi Lensimbi Kufanele Lihlolwe Ngamanzi Ngalinye Ngalinye. Ingcindezi Yokuhlola Ephezulu Ingama-20 MPa. Ngaphansi Kwengcindezi Yokuhlola, Isikhathi Sokuzinza Akufanele Sibe Ngaphansi Ko-10 S, Futhi Ipayipi Lensimbi Akufanele Livuze. Noma Ukuhlolwa Kwe-Hydraulic Kungashintshwa Ukuhlolwa Kwamanje kuka-Eddy Noma Ukuhlolwa Kwe-Magnetic Flux Ukuvuza.
Ukuhlolwa Okungonakali:
Amapayipi Adinga Ukuhlolwa Okuningi Kufanele Ahlolwe Ngomshini Ngalinye Ngalinye. Ngemuva kokuthi Ingxoxo Idinga Imvume Yeqembu Futhi Icaciswe Kunkontileka, Okunye Ukuhlola Okungabhidli Kungangezwa.
Ukuhlolwa kokucaba:
Amashubhu Anobubanzi Bangaphandle Omkhulu Kuno-22 Mm Azofakwa Ukuhlolwa Kokucaba. Akukho Ukuwohloka Okubonakalayo, Amachashazi Amhlophe, Noma Ukungcola Okufanele Kuvele Phakathi Naso sonke Isilingo.
Ukuhlolwa kokuqina:
OkwePipe Of Grades P91, P92, P122, kanye ne-P911, Brinell, Vickers, Noma Ukuhlolwa Kokuqina Kwe-Rockwell Kuzokwenziwa Ngesifanekiso Esisuka Kwilothi Ngalinye.
