Chofunikira Choyesa
Mayeso a Hydraustatic:
Chitoliro Chachitsulo Chiyenera Kuyesedwa Hydraulically Mmodzi Ndi Mmodzi. Kupanikizika Kwambiri Kwambiri Ndi 20 MPa. Pansi pa Kupanikizika kwa Mayesero, Nthawi Yokhazikika Iyenera Kusachepera 10 S, Ndipo Chitoliro Chachitsulo Siyenera Kutayikira. Kapena Mayeso a Hydraulic Atha Kusinthidwa Ndi Mayeso Apano a Eddy Kapena Mayeso a Magnetic Flux Leakage.
Mayeso Osawononga:
Mipope Yomwe Imafunika Kuyang'ana Kwambiri Iyenera Kuyang'aniridwa 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.
