Mibvunzo Inowanzo bvunzwa
Ko exothermic welding inogamuchirwa here pakubatanidza cathodic protection connections pamapaipi?
Ehe. Kubatanidza exothermic (thermit) welding inzira yakajairika yekubatanidza ma test leads, anode cables uye bond wires kumapaipi akavigwa nekuti inogadzira permanent molecular bond isina simba rekunze. Zvinodiwa zveCP system zviri pasi pe AMPP/NACE SP0169 uye, kune offshore lines, ISO 15589-2:2024; connection permanence inowanzo shandiswa ne IEEE 837.
Ndeupi musiyano uripo pakati pehupfu hwethermit welding nethermit welding flux?
Upfu ihwohwo hunochinja-chinja — musanganiswa we copper oxide ne aluminium unogadzira copper yakanyungudutswa yejoinhi. Kuyerera kunotsigira reaction nekuchenesa uye kunyorovesa pamusoro kuitira kuti copper ibatane isina maburi. Zvose zvinodyiwa kamwe chete pajoinhi, uye zvose zvinofanirwa kuenderana ne conductor nehukuru hwauri kusonera.
Chiumbwa chimwe chegrafiti chinogara nesimbi ngani?
Hupenyu hwedu hwekushanda hwakanyorwa mufekitori hunosvika 80–100 weld joints paforoma imwe neimwe, tichifunga kuti kuchengetwa kwakaoma uye kubata kwakanyatsonaka.
