Mayankho Odalirika Olumikizirana a Makina Opopera Mapaipi Opanikizika
1. Chidule Chachikulu ndi Malo Ogulitsira
EN 10253-2 ndiye muyezo waukulu ku Europe wa mafakitale opangidwa ku Europezolumikizira zitsulo zolumikizira matakoamagwiritsidwa ntchito m'mapaipi opondereza.
Mu muyezo uwu,Mtundu Bikuyimiramulingo wapamwamba kwambiri wogwirira ntchito, yokhala ndi kulekerera kolimba kwa mawonekedwe, zofunikira zowunikira bwino, komanso mawonekedwe abwino a pamwamba.
EN 10253-2 Zolumikizira za Mtundu B zimagwiritsidwa ntchito kwambirimapaipi otsika ndi apakatipoyendetsa madzi, nthunzi, gasi, mafuta, ndi madzi osiyanasiyana a m'mafakitale, makamaka komwe ubwino wa kuwotcherera ndi kulondola kwa magawo ndizofunikira kwambiri.
2. Mtundu B vs. Mtundu A - Kuyerekeza Kuchita Zinthu Mwaukadaulo

7. Njira Yopangira ndi Kuyang'anira
EN 10253-2 Zolumikizira za Mtundu B zomwe zimaperekedwa ndi Womic Steel zimapangidwa pogwiritsa ntchito njira yowongoleranjira zopangira kutentha kapena kuzizira, kutsatiridwa ndi kulinganiza kwa miyeso.
Kuwunika ndi kuyesa kofunikira kumaphatikizapo:
● Kusanthula mankhwala (spectrometer)
● Kuyesa kwa makina (kolimba, kukhudza)
● Kuyang'ana miyeso
● Kuyeza makulidwe a khoma
● Kuyang'ana zinthu zooneka ndi pamwamba
● NDT yosankha (UT / MT) ngati mupempha
Zinthu zonse zimaperekedwa ndiZikalata za EN 10204 3.1 kapena 3.2, kuonetsetsa kuti zinthuzo zikutsatira bwino. 
8. Kuchuluka kwa Kupanga, Kulongedza ndi Kutumiza
● Palibe MOQChidutswa chimodzi chovomerezeka
●Miyeso yokhazikikaKutumiza mwachangu kuchokera ku stock
●Kukula kwakukulu / zipangizo zapadera: Yopangidwa kuti ikonzedwe
●Kulongedza: Chitetezo cha VCI choletsa dzimbiri + chonyamula zinthu zoyenda panyanja
●Kayendetsedwe ka zinthu: Mayankho abwino kwambiri oyendera panyanja, sitima, ndi maulendo ambiri
9. Mapulogalamu Odziwika
EN 10253-2 Zolumikizira za Mtundu B zimagwiritsidwa ntchito kwambiri mu:
1. Makina otenthetsera ndi HVAC
2. Mapaipi opangira zinthu zamafakitale
3. Malo oyeretsera madzi
4. Mapaipi amphamvu ndi ogwiritsidwa ntchito
5. Makina othandizira a boiler
10. Chifukwa Chosankha Chitsulo cha Womic
Kutsatira malamulo onseEN 10253-2 Mtundu B
● Kupeza zinthu zopangira zokhazikika
● Kutha kuwunika kwathunthu
● Kupanga kosinthasintha komanso kuyankha mwachangu
● Chidziwitso cha padziko lonse cha kupereka ntchito
Timadzitamandira ndi ntchito zathu zosintha zinthu, kupanga zinthu mwachangu, komanso netiweki yathu yotumizira zinthu padziko lonse lapansi, kuonetsetsa kuti zosowa zanu zikukwaniritsidwa molondola komanso mwaluso.
