Ipayipi elimnyama lensimbi lenziwe ngensimbi engakaze ifakwe.Igama laso livela ku-scaly, umbala omnyama we-iron oxide enamathela endaweni yayo.Isetshenziswa ezinhlelweni ezingadingi insimbi.

Ipayipi lensimbi elimnyama(Ipayipi lensimbi elingagcotshiwe) libizwa ngokuthi “elimnyama” ngenxa yesikali se-iron-oxide esinombala omnyama esakhiwe phezu kwalo;ngokuvamile asetshenziselwa amapayipi okufudumeza amanzi ashisayo anengcindezi ephansi.Itholakala ngamashejuli amabili (ishejuli 40 kanye nohlelo 80).Umehluko phakathi kwamashejuli amabili ububanzi bodonga lwepayipi.Isheduli engu-80 yepayipi elimnyama lensimbi lishubile kuneshejuli 40. Ezindaweni eziningi ishejuli engu-80 iyadingeka kumugqa we-condensate ngenxa ye-asidi nokungcola.Ngingayincoma kakhulu ngeshejuli engu-40.

Lapho ipayipi lensimbi lakhiwe, kwakheka isikali se-oxide esimnyama ebusweni balo ukuze sinikeze isiphetho esibonakala kulolu hlobo lwepayipi.Ngenxa yokuthi insimbi iyakwazi ukugqwala nokugqwala, ifektri nayo iyigcoba ngamafutha ayisivikelo.Lezo zinsimbi ezimnyama zisetshenziselwa ukukhiqiza ipayipi neshubhu, engeke igle isikhathi eside futhi idinga ukulungiswa okuncane kakhulu.Ithengiswa ngobude obujwayelekile obungamafidi angama-21 TBE.Isebenza kabanzi ezintweni ezijwayelekile ezisetshenziswa emanzini, kugesi, emoyeni nasesitimuni, amapayipi ensimbi amnyama namashubhu asetshenziselwa ukusatshalaliswa kwegesi ngaphakathi nangaphandle kwendlu kanye nokujikeleza kwamanzi ashisayo kuma-boiler systems.Ibuye isetshenziselwe ukwenza amapayipi kalayini ezimbonini zikawoyela nezamafutha, emithonjeni yamanzi nasezinjongo zamanzi, igesi kanye nendle.
