Ipayipi lensimbi elinembile elingenamthungo liyimpahla yepayipi yensimbi enembe kakhulu ecutshungulwa ngomdwebo obandayo noma ngokuginqika okushisayo. Ngenxa yokuthi izindonga zangaphakathi nezangaphandle zamapayipi ensimbi anembayo azinalo ungqimba lwe-oxide, angakwazi ukumelana nokucindezela okuphezulu ngaphandle kokuvuza, abe nokunemba okuphezulu, ukushelela okuphezulu, akukho ukuguquguquka ngesikhathi sokugoba okubandayo, futhi akukho ukwanda. Ukwakheka kwamakhemikhali kwamapayipi ensimbi anembile ngu-C, Si, Mn, S, P, no-Cr, uma kuqhathaniswa nensimbi eqinile njengensimbi eyindilinga, ipayipi lensimbi engenamthungo lilula ngesisindo uma ukugoba namandla okugoqa kufana. Kuyinsimbi eyongayo enezigaba ezihlukene esetshenziswa kabanzi ekukhiqizeni izingxenye zesakhiwo nemishini.

Izinto ezisetshenziswa kakhulu zokunemba kwamapayipi ensimbi angenamthungo yi-10#, 20#, 35#, kanye no-45#. Izinto eziningi zingakhiqizwa. Uma nje insimbi ingenzima kakhulu, ingakhiqizwa ngokwezidingo. Okufana njengokuthi: 10#, 35#, 16Mn, 40Cr.

Ukusebenza nezici zokunemba kwepayipi lensimbi engenamthungo
Izici eziyinhloko: Izindonga zangaphakathi nangaphandle zepayipi lensimbi zinokunemba okuphezulu nokushelela okuphezulu. Ngemuva kokwelashwa kokushisa, ipayipi lensimbi alinayo isendlalelo se-oxidation futhi udonga lwangaphakathi luhlanzeke kakhulu. Ipayipi lensimbi lingakwazi ukumelana nokucindezela okuphezulu, aliguquki ngesikhathi sokugoba okubandayo, alinayo imifantu ekuqhumeni nasekufakeni isicaba, futhi lingasetshenziselwa imisebenzi ehlukahlukene eyinkimbinkimbi. Ukuguqulwa nokucutshungulwa kwemishini. Umbala wepayipi lensimbi: omhlophe onombala ogqamile, ukucwebezela kwensimbi ephezulu.
Ukusetshenziswa okuyinhloko: amapayipi ensimbi ezimoto, nabasebenzisi abanezidingo eziphezulu zokunemba nokushelela kwamapayipi ensimbi.

Amapayipi ensimbi angenamthungo anembile ngokuvamile anezinqubo ezimbili: umdwebo obandayo noma ukugoqa okubandayo
1. Ipayipi lensimbi elikhishwe ngenqubo yokudweba ebandayo lithola ukwelashwa okunemba okuphezulu ukuze kwakheke ipayipi lensimbi elibizwa ngokuthi ipayipi lensimbi eliqinile elidonswa ngokubanda.
2. Ipayipi lensimbi elikhishwe ngenqubo yokugoqa ebandayo lithola ukwelashwa okunemba okuphezulu ukuze kwakheke ipayipi lensimbi elibizwa nge-cold-rolled precision precision seamless steel pipe.

Ngokuvamile, kungakhathaliseki ukuthi ipayipi lensimbi engenamthungo elidonsa abandayo elidonsa ngokubanda noma ipayipi lensimbi engenamthungo eligoqeka ngokubanda, lolu hlobo lwepayipi lensimbi elinemba linokunemba okuphezulu, indawo ebushelelezi, futhi alukho ungqimba lwe-oxide ezindongeni zangaphakathi nezingaphandle. Lolu hlobo lwamapayipi ensimbi angenamthungo aphezulu anembayo aphezulu lungaba Ukukhiqizwa, kumasilinda asebenzisa amanzi kanye neminye imikhiqizo.
