Konke esikwenzayo kuvame ukuhileleka kumgomo wethu ” Umthengi ozoqala ngaye, Thembela ekuqaleni, ukunikela phezu kokupakishwa kwezinto zokudla nokuvikela imveloChina Steel Pipe, Ipayipi Elingenamthungo, Sisungule ubudlelwano bebhizinisi besikhathi eside, obuzinzile futhi obuhle nabakhiqizi nabathengisi abaningi emhlabeni jikelele. Njengamanje, besibheke phambili ekubambisaneni okukhulu nakakhulu namakhasimende aphesheya okusekelwe ezinzuzweni ezifanayo. Qiniseka ukuthi uzizwa ukhululekile ukusithinta ukuze uthole imininingwane eyengeziwe.
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.
