Ipayipi lensimbi elicwebezelayo eliqediwe liyipayipi lensimbi elinokunemba okuphezulu ngemva kokuqeda ukudweba noma ukugoqa okubandayo. Ngenxa yokuthi izindonga zangaphakathi nezangaphandle zamapayipi acwebezelayo anembile azinawo ungqimba lwe-oxide, akukho ukuvuza ngaphansi kokucindezela okuphezulu, ukunemba okuphezulu, ukuqeda okuphezulu, akukho ukuguquka ngesikhathi sokugoba okubandayo, ukuvutha, ukucaba futhi akukho mifantu, njll., asetshenziswa kakhulu ukukhiqiza imikhiqizo yezingxenye zomoya noma ze-hydraulic, njengezilinda noma amasilinda kawoyela, angaba amapayipi angenamthungo noma amapayipi ahlanganisiwe. Ukwakheka kwamakhemikhali kwepayipi elicwebezelayo elinembile kufaka phakathi i-carbon C, i-silicon Si, i-manganese Mn, i-sulfur S, i-phosphorus P, kanye ne-chromium Cr.
Izici eziyinhloko zokuqeda ipayipi elikhanyayo:
Izindonga zangaphakathi nezangaphandle zepayipi lensimbi zinokunemba okuphezulu kanye nokuqeda okuphezulu. Ngemva kokwelashwa kokushisa, ipayipi lensimbi alinawo ungqimba lwe-oxide, kanti udonga lwangaphakathi luhlanzekile kakhulu. Ipayipi lensimbi lithwala umfutho ophezulu, ukugoba okubandayo akuguquguquki, futhi ukuvutha nokuthamba akuqhekeki. Ipayipi lensimbi eligoqiwe eliqediwe elinikezwe yi-Tianjin Century Zoomlion lingasetshenziswa ekuguqulweni okuhlukahlukene okuyinkimbinkimbi kanye nokucubungula ngomshini. Umbala wepayipi lensimbi: omhlophe ngokukhanya, one-luster ephezulu yensimbi.
Isimo esijwayelekile, sezinto ezibonakalayo kanye nokulethwa kokuqeda-amashubhu agqamile agoqiwe

Isimo sokulethwa okuyinhloko: NBK (+N), GBK (+A), BK (+C), BKW (+LC), BKS (+SR)
Ukusetshenziswa kweqeda-amashubhu agqamile agoqiwe
Izimoto, izesekeli zemishini kanye neminye imishini enezidingo eziphezulu zokunemba nokushelela kwamapayipi ensimbi. Manje abasebenzisi bamapayipi ensimbi aqediwe aphelele abagcini nje ngokuba yilabo abanezidingo eziphezulu zokunemba nokuqedwa. Ngenxa yokuthi ukunemba kwamapayipi aqediwe aphelele kuphezulu futhi ukubekezelelana kungagcinwa ezintanjeni ezingu-2-8, abasebenzisi abaningi bokucubungula ngomshini bashintsha kancane kancane amapayipi ensimbi angenamthungo noma insimbi eyindilinga abe amapayipi acwebezelayo aqediwe aphelele ukuze basindise umsebenzi, izinto zokwakha kanye nesikhathi.
