Uhlolojikelele
Isicelo
Isetshenziswa kakhulu ukwenza insimbi yesakhiwo sekhabhoni ephezulu, ipayipi elinomfutho ophansi ophakathi nendawo, ipayipi elishisayo elishisayo elingenamthungo le-carbon steel pipe.
Ibanga Eliyinhloko
Ibanga lensimbi ephezulu ye-carbon structural: 10#,20#

Isidingo Sokuhlola
Ukuhlolwa kokucaba
Amashubhu ensimbi anobubanzi obungaphandle obungaphezu kuka-22 mm futhi kufika ku-400 mm, nogqinsi lodonga olungaphezu kuka-10 mm kufanele luhlolwe ukucaba. Ngemuva kokuthi amasampula abekwe isicaba
Ukuhlolwa kokugoba
Amashubhu ensimbi anobubanzi obungaphandle obungekho ngaphezu kuka-22 mm kufanele ahlolwe ukugoba. I-engeli yokugoba ingu-90o. Irediyasi egobayo iphinda izikhathi ezingu-6 ububanzi bangaphandle beshubhu lensimbi. Ngemva kokugoba isampula, akukho mifantu noma imifantu evunyelwe ukuthi ivele kusampula.
Ukuhlolwa kwe-Macroscopic
Kumashubhu ensimbi enziwe ngokuqondile ama-billet asakazwa ngokuqhubekayo noma ama-ingots ensimbi, inkampani enikezelayo kufanele iqinisekise ukuthi awekho amachashaza amhlophe, ukungcola, amabhamuza omoya angaphansi komhlaba, amabala ogebhezi lwekhanda noma ukwendlaleka kwezicubu ze-asidi ezifakwe emanzini abandayo ze-billet noma ithubhu lensimbi.
Ukuhlola okungabhubhisi
Ngokwesicelo seqembu elifunayo, okube sekuxoxiswana ngalo phakathi kwezinhlangothi ezihlinzekayo nezifuna ngamandla futhi kuboniswe esivumelwaneni, ukutholwa kwamaphutha e-ultrasonic kungase kwenziwe ngakunye kumashubhu ensimbi. Iphutha lemanuwali le-longitudinal leshubhu yesampula yereferensi kufanele lihlangabezane nezidingo zebanga lokwamukelwa kwangemva kokuhlolwa C8 elicaciswe ku-GB/T 5777-1996.
