[Kopisha] GB 3087 ipayipi lensimbi elijwayelekile elingenamthungo kubhayela ingxubevange Ukucindezela okuphansi Ukucindezela okumaphakathi

Incazelo emfushane:

I-GB T3087-2008

umfutho ophansi Ipayipi le-boiler elicindezelayo eliphakathi nendawo elishisa kakhulu ipayipi lensimbi elisezingeni eliphezulu elingenamthungo

Ikakhulukazi yemakethe yase-India ngesitifiketi se-IBR

I-GB 3087-2008″ishubhu yensimbi engenamthungo kubhayela wengcindezi ephansi nemaphakathi” kanye ne-GB5310-2008″ishubhu lensimbi engenamthungo kubhayela onengcindezi ephezulu”. Ikhwalithi yokubukeka: imifantu, ukugoqa, ukugoqeka, izibazi, ukuhlukana kanye nemibimbi akuvunyelwe endaweni engaphakathi nangaphandle yepayipi lensimbi.Lokhu kuphazamiseka kufanele kuqedwe ngokuphelele. futhi ubukhulu bodonga lwangempela endaweni evulekile akumele bube ngaphansi kobukhulu obuncane obuvunyelwe bodonga.

    Ukubekezelelana

    Ukuchezuka okuvumelekile kobubanzi obungaphandle bamashubhu ensimbi

    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.
