Intshayelelo kwiityhubhu zentsimbi ezifakwe iBlack Backed Steel

Umbhobho weNtsimbi oNxibeleleneyo omnyama(BAP) luhlobo lombhobho wentsimbi oye wafakwa umbala omnyama. I-Annealing yinkqubo yonyango lobushushu apho intsimbi ifudunyezwa kubushushu obufanelekileyo ize ipholiswe kancinci ukuya kubushushu begumbi phantsi kweemeko ezilawulwayo. I-Black Annealed Steel Pipe yenza umphezulu we-iron oxide emnyama ngexesha lenkqubo ye-annealing, nto leyo eyinika ukumelana nokugqwala okuthile kunye nembonakalo emnyama.

Izinto zombhobho wentsimbi emnyama efakwe intsimbi

1. ephantsiintsimbi yekhabhoni(Intsimbi yeCarbon ephantsi): intsimbi yecarbon ephantsi yenye yezona zinto ziqhelekileyo zepayipi yesikwere ezimnyama ezifakwe i-annealed.
