Mayeso Opindika— chitoliro chokwanira chiyenera kupindika mozizira mpaka madigiri 90 mozungulira mandrel yozungulira.
Kuyesa kosalala - ngakhale kuyesa sikofunikira, chitolirocho chiyenera kukwaniritsa zofunikira pa mayeso okosalala.
Kuyesa kwa hydro-static—kupatula ngati kuli kololedwa, kutalika kulikonse kwa chitoliro kuyenera kuyesedwa kwa hydro-static popanda kutuluka kudzera pakhoma la chitoliro.
Mayeso amagetsi osawononga - m'malo mwa mayeso a hydro-static, thupi lonse la chitoliro chilichonse liyenera kuyesedwa ndi mayeso amagetsi osawononga. Pamene mayeso amagetsi osawononga achitika, kutalika kuyenera kulembedwa ndi zilembo "NDE"
Kuyesa kwa ultrasound.
Kufufuza kwa eddy current.
