Mayeso a Hydraustatic:
Chitoliro chachitsulo chiyenera kuyesedwa ndi Hydraulically chimodzi ndi chimodzi. Kupanikizika kwakukulu kwa mayeso ndi 20 MPa. Pansi pa kupanikizika kwa mayeso, nthawi yokhazikika iyenera kukhala osachepera 10 S, ndipo chitoliro chachitsulo sichiyenera kutuluka. Kapena mayeso a Hydraulic akhoza kusinthidwa ndi Eddy Current Testing kapena Magnetic Flux Leakage Testing.
Mayeso Osawononga:
Mapaipi Omwe Amafuna Kuyang'aniridwa Kwambiri Ayenera Kuwunikidwa Mothandizidwa ndi Ultrasonical Limodzi ndi Limodzi. Pambuyo pa Kukambirana Kumafuna Chilolezo cha Gululo Ndipo Chafotokozedwa Mu Pangano, Mayeso Ena Osawononga Akhoza Kuwonjezedwa.
Mayeso Ophwanyira:
Machubu Okhala ndi Diameter Yakunja Yoposa 22 mm Ayenera Kuyesedwa Mopepuka. Palibe Delamination Yooneka, Madontho Oyera, Kapena Zodetsa Zomwe Ziyenera Kuchitika Pa Kuyesera Konse.
Mayeso a Kuuma:
Pa Mapaipi A Magiredi P91, P92, P122, ndi P911, Mayeso a Brinell, Vickers, kapena Rockwell Hardness Ayenera Kupangidwa Pa Chitsanzo Chochokera ku Loti Iliyonse
