Monga payipi yofunikira yoyendera, mapaipi achitsulo osasunthika amagwiritsidwa ntchito kwambiri mumafuta, gasi, makampani opanga mankhwala, mphamvu zamagetsi ndi mafakitale ena. Pogwiritsira ntchito, ayenera kuyesedwa mosamalitsa kuti atsimikizire ubwino ndi chitetezo cha payipi. Nkhaniyi iwonetsa kuyesa kwa chitoliro chosasunthika kuchokera kuzinthu ziwiri: kuyesa zinthu ndi njira.

Zinthu zoyeserera zikuphatikiza mawonekedwe, kukula, mtundu wapamtunda, kapangidwe kake, kukhazikika, mphamvu, kusalala, kuwomba, kupindika, kuthamanga kwa hydraulic, zosanjikiza zamagalasi, etc.
Njira yodziwira
1. Kuyesa kwamphamvu
2. Kuyesa kwamphamvu
3. Mayeso osalala
4. Mayeso okulitsa
5. Mayeso opindika
6. Mayeso a Hydraulic
7. Kuwunika kwagalasi lagalasi
8. Ubwino wa pamwamba umafuna kuti pasakhale ming'alu yowonekera, mapiko, zipsera, mabala ndi delamination pakatikati ndi kunja kwa chitoliro chachitsulo.
Kuphatikiza apo, kuyendera kudzachitika malinga ndi zosowa za makasitomala, mongaGB/T 5310-2017opanda zitsulo mapaipi kwama boilers apamwamba.
Kapangidwe ka mankhwala: Chitsulo chimakhala ndi zinthu monga chromium, molybdenum, cobalt, titaniyamu, ndi aluminiyamu, zomwe zimatha kusintha kukana kutentha ndi kukana kwa dzimbiri.
Makina katundu: zokolola mphamvu ≥ 415MPa, kumakoka mphamvu ≥ 520MPa, elongation ≥ 20%.
Kuyang'anira mawonekedwe: Palibe cholakwika chilichonse, makwinya, makwinya, ming'alu, zokopa kapena zolakwika zina zowoneka bwino pamtunda.
Kuyesa kosawononga: Gwiritsani ntchito akupanga, ray ndi njira zina kuyesa mapaipi achitsulo kuti muwonetsetse kuti mkati mwa mipope yachitsulo yopanda chilema ndi yopanda chilema.
