Abahlinzeki Abaphezulu be-GB3087 Carbon Steel Seamless Pipe
Siyazi ukuthi siyachuma kuphela uma singaqinisekisa ukuncintisana kwethegi yethu ehlanganisiwe nekhwalithi enenzuzo ngesikhathi esifanayo ku-Top Suppliers GB3087 Carbon Steel Seamless Pipe, Ngenkathi sisebenzisa ukuthuthukiswa komphakathi nomnotho, inkampani yethu izogcina imfundiso ethi “Gxila ku- ukwethemba, ikhwalithi ephezulu kuqala”, ngaphezu kwalokho, sithembele ekwenzeni uhambo olude olukhazimulayo ngekhasimende ngalinye.
Siyazi ukuthi siyaphumelela kuphela uma singaqinisekisa ukuncintisana kwethegi yethu yentengo ehlanganisiwe kanye nekhwalithi enenzuzo ngesikhathi esifanayoIpayipi Lensimbi LaseChina Elingenamthungo kanye Nepayipi Lensimbi, Ukwaneliseka kwekhasimende kuwumgomo wethu wokuqala. Umgomo wethu ukuphishekela ikhwalithi ephezulu kakhulu, senze inqubekelaphambili eqhubekayo. Siyakwamukela ngokuzithoba ukuthi nenze inqubekela phambili nibambene nathi, futhi sakhe ikusasa eliqhakazile ndawonye.
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.
