Ndandanda 80 carbon steel pipe ndi mtundu wa chitoliro chomwe chimadziwika ndi khoma lake lalikulu poyerekeza ndi ndondomeko zina, monga Ndandanda 40. "Ndandanda" ya chitoliro imatanthawuza makulidwe ake a khoma, zomwe zimakhudza kuthamanga kwake ndi mphamvu zake.
Zofunika Kwambiri pa Ndandanda 80 Carbon Steel Pipe
1. Makulidwe a Khoma: Okhuthala kuposa Ndandanda 40, kupereka mphamvu zazikulu ndi kulimba.
2. Kuthamanga Kwambiri: Kuthamanga kwapamwamba kwambiri chifukwa cha kuchuluka kwa khoma, ndikupangitsa kuti ikhale yoyenera kugwiritsira ntchito kuthamanga kwambiri.
3. Zida: Zopangidwa ndi zitsulo za carbon, zomwe zimapereka mphamvu zabwino komanso zolimba, komanso kukana kuvala ndi kuwonongeka.
4. Mapulogalamu:
Industrial Piping: Amagwiritsidwa ntchito m'mafakitale monga mafuta ndi gasi, kukonza mankhwala, ndi kupanga magetsi.
Mapaipi: Oyenera mizere yoperekera madzi amphamvu kwambiri.
Kumanga: Kugwiritsidwa ntchito pamapangidwe omwe amafunikira mphamvu zambiri.

Konzani 80 Carbon Steel Pipe
Ubwino:
Mphamvu Zapamwamba: Makoma okhuthala amapereka kukhulupirika kwadongosolo.
Kukhazikika: Kulimba kwachitsulo cha Carbon komanso kukana kuvala kumapangitsa mapaipiwa kukhala okhalitsa.
Kusinthasintha: Ndikoyenera kugwiritsidwa ntchito ndi mafakitale osiyanasiyana.
Zoyipa:
Kulemera kwake: Makoma okhuthala amapangitsa kuti mapaipi azilemera komanso kukhala ovuta kuwagwira ndikuyika.
Mtengo: Nthawi zambiri ndi wokwera mtengo kuposa mapaipi okhala ndi makoma owonda chifukwa cha kuchuluka kwa zinthu zomwe zimagwiritsidwa ntchito.
