I-AMA isanda kushicilela ucwaningo oluningiliziwe lwamakhasi angaphezu kuka-180+ endaweni yayo yokugcina impahla emakethe ye-'Malleable Iron Pipe Fittings' ehlanganisa izici ezithakazelisayo zemakethe nezimo ezisekelayo zentuthuko kuze kube ngu-2025. Ucwaningo luhlinzeka ngokuhlukana kosayizi wemakethe ngemali engenayo kanye nevolumu* emazweni asafufusa. kanye nezigaba ezibalulekile zebhizinisi kanye namazwana mayelana nezici ezithrendayo, abashayeli bokukhula.
Insimbi ethambileyo, ejikijelwe njengensimbi emhlophe, iyi-carbide ethambileyo eyakhiwe nge-matrix ye-pearlitic. I-Annealing iyenziwa ukuze kuguqulwe isakhiwo sokuqala esinama-brittle sibe ifomu elithambile. Ukwelashwa kwe-annealing kuthuthukisa ukusebenza kwayo, i-ductility, nokuqina. Ukufakwa kwamapayipi ensimbi athambileyo kwenziwa ngokuyinhloko ngensimbi eyinsimbi nama-alloys akhiwe ngensimbi, i-carbon, ne-silicon. Izifakelo zamapayipi athambile zisetshenziswa ukuze kuxhunywe amapayipi amabili noma ngaphezulu noma amashubhu, ukuxhuma ipayipi kwezinye izinto, ukuguqula indlela okugeleza ngayo uketshezi, noma ukuvala ipayipi.
