Ipayipi lensimbi elinembile elingenamthungo lidonswa ukubanda noma eligoqelwe ngokushisa ngemva kokwelashwa kwepayipi lensimbi elinemba kakhulu.Njengokunemba kwepayipi lensimbi engenamthungo ngaphakathi nangaphandle kodonga lwesendlalelo esingena-oxidized sepayipi lensimbi elingenamthungo, ukumelana nokucindezela okukhulu ngaphandle kokuvuza, ukunemba okuphezulu, ukuqeda okuphezulu, ukuguquguquka okubandayo, ukuvutha, ukucaba ngaphandle kokuqhekeka, njll., ikakhulukazi esetshenziswa ukukhiqiza izingxenye zomoya noma ezisebenza ngogesi. Imikhiqizo, njengamasilinda noma amasilinda, yenziwe ngamashubhu angenamthungo.Ipayipi lensimbi engenamthungo enembile ukwakheka kwamakhemikhali ekhabhoni C, i-silicon Si, i-manganese Mn, isulfure S, i-phosphorus P, i-chromium Cr.

Umehluko phakathi kokunemba kwepayipi lensimbi nepayipi lensimbi elingenamthungo

I-1, izici eziyinhloko zepayipi lensimbi engenamthungo ayikho i-welding seam, ingakwazi ukumelana nokucindezela okukhulu.Umkhiqizo ungaba yizingxenye ezikhahlamezekile kakhulu njenge-cast noma izingxenye ezidonswa ngokubanda.

I-2, ipayipi yensimbi enembile eminyakeni yamuva kunemikhiqizo, ikakhulukazi ngaphakathi kwembobo, usayizi wodonga lwangaphandle unokubekezelelana okuqinile kanye nobulukhuni.

Izici zokunemba kweshubhu lensimbi engenamthungo

1. Ububanzi obuncane obungaphandle.

2. Ukunemba okuphezulu kungenza ukukhiqizwa kwenqwaba encane.

3. Ukudonswa okubandayo kuqedile ukunemba okuphezulu, ikhwalithi enhle yendawo.

4. Indawo ye-Tube cross-sectional iyinkimbinkimbi kakhulu.

5. Ukusebenza kwamapayipi kungcono, insimbi eminyene kakhulu.
