Mayeso a Hydraustatic:
Chitoliro Chachitsulo Chiyenera Kuyesedwa Hydraulically Mmodzi Ndi Mmodzi. Kuthamanga Kwambiri Kwambiri Ndi 20 MPa. Pansi pa Kupanikizika kwa Mayesero, Nthawi Yokhazikika Iyenera Kukhala Yosachepera 10 S, Ndipo Chitoliro Chachitsulo Siyenera Kutuluka. Kapena Mayeso a Hydraulic Atha Kusinthidwa Ndi Mayeso Apano a Eddy Kapena Mayeso a Magnetic Flux Leakage.
Mayeso Osawononga:
Mipope Amene Amafuna Kuyendera Kwambiri Ayenera Kuyang'aniridwa Mwachindunji Mmodzi Ndi Mmodzi. Pambuyo Kukambitsirana Kumafuna Chivomerezo cha Phwando Ndipo Kufotokozedwa Mumgwirizanowu, Mayeso Ena Osawononga Akhoza Kuwonjezedwa.
Mayeso a Flattening:
Machubu Okhala Ndi Diameter Yakunja Yoposa 22 mm Adzayesedwa Kusanja. Palibe Delamination Yowoneka, Mawanga Oyera, Kapena Zonyansa Zomwe Ziyenera Kuchitika Pakuyesa Konse.
Mayeso Olimba:
Kwa Pipe Of Giredi P91, P92, P122, Ndi P911, Brinell, Vickers, Kapena Rockwell Hardness Mayeso Adzapangidwa Pachitsanzo cha Loti Iliyonse.
