Ngenxa yezinqubo ezahlukene zokukhiqiza, ipayipi lensimbi elingenamthungo lingahlukaniswa ngezinhlobo ezimbili:ipayipi lensimbi eligoqiwe elishisayo (extrusion).kanye nepayipi lensimbi elibandayo elidonswe (eligingqelwe) elingenamthungo.Amashubhu adonswe abandayo (agoqiwe).zihlukaniswe zibe izinhlobo ezimbili: amashubhu ayindilinga namashubhu amise okwenzeke.
Ukubuka konke kwenqubo
I-hot-rolled (extrusion steel seamless pipe): ishubhu eliyindilinga elingenalutho lokushisisa imbobo enamaroll amathathu, ukugoqeka okuqhubekayo noma ukulinganisa kwepayipi (noma ukunciphisa ububanzi) okupholisa ishubhu elingenalutho lokuqondisa uhlelo lokuhlola amanzi (noma ukutholwa kwamaphutha) inqolobane.
Ipayipi lensimbi elibandayo elidonsayo (eligoqiwe) elingenamthungo:ithubhu eliyindilinga elingenalutho ukushisisa ikhanda elinembobo ene-annealing acid pickling oil (i-copper plating) umdwebo obandayo onamapayipi amaningi (ukuginqika okubandayo) ukwelapha ukushisa kweshubhu elingenalutho ukuqondisa ukuhlolwa kwe-hydraulic (ukuhlola) uphawu lokugcina.
