Inkqubo yokuVelisa

Umgangatho we-BS EN 10210 uvumela ukuba kusetyenziswe inani leenkqubo zokuvelisa ukuvelisa amacandelo angenanto, kuquka iinkqubo ezingenamthungo kunye ne-welded.Ngaphakathi kwenkqubo ye-welding, iindlela eziqhelekileyo zibandakanyaLSAW(SAWL), SSAW (HSAW), kwayeERW.

Imibhobho yentsimbi edityanisiweyo ye-LSAW yenziwa ikakhulu ngokwenza iipleyiti zentsimbi kwiityhubhu kusetyenziswa inkqubo yokubumba i-JCOE, ilandelwa kukuwelda kusetyenziswa i-arc enamacala amabini.DSAW) itekhnoloji ye-welding, kwaye igqitywe ngenani lokuhlolwa kunye nonyango.

Ukhetha njani inkqubo yokuvelisa eyiyo?Ziziphi iiyantlukwano kunye neenzuzo zombhobho wensimbi ongenamthungo, i-LSAW, i-arc welding ephantsi kwamanzi, kunye ne-arc welding ephantsi kwamanzi?Kwaye yintoni uluhlu lobungakanani benkqubo nganye?Ungacofa ikhonkco elilandelayo ukuze uyijonge.

I-BS EN 10210 S275J0H iiPropati zoomatshini

Iipropathi zoomatshini ze-BS EN 10210 zibandakanya amandla esivuno, amandla okuqina, ubude, kunye neempawu zempembelelo.

Imeko yoMphezulu

Amacandelo angenamngxuma aya kuba nomphezulu ogudileyo ohambelana nendlela yokuvelisa esetyenziswayo;amaqhuma, imingxunya, okanye imijelo enzulu yobude obuvela kwinkqubo yokwenziwa ivumelekile, ngaphandle kokuba ubukhulu bungaphakathi kokunyamezelana.

I-EN 10210 Umphezulu wombhobho wentsimbi ulungele ukugalela idiphu eshushu.

Uvavanyo loxinzelelo lweHydrostatic

I-EN 10210 ayifuni uvavanyo lwe-hydrostatic yoxinzelelo lwemibhobho yentsimbi.

Oku kungenxa yokuba iimveliso ezisemgangathweni ze-EN 10210 zisetyenziselwa iinjongo zesakhiwo hayi kwiinkqubo zombhobho ekufuneka ziphantsi koxinzelelo.

Ukuba uvavanyo loxinzelelo lwe-hydrostatic luyafuneka, ireferensi inokwenziwa kwi-EN 10216 (iityhubhu zensimbi ezingenamthungo) okanye i-EN 10217 (i-welded steel tubes) imigangatho.

Uvavanyo olungangonakalisi (NDT)

Akukho mfuneko efunekayo kumgangatho wokuqhuba i-NDT kwimibhobho yentsimbi yecandelo elingenanto.

Ukuba i-NDT yenziwa kwimibhobho yensimbi edibeneyo, ezi mfuno zilandelayo zingabhekiswa kuzo.

Amacandelo adityanisiweyo oMbane

Kwimibhobho yentsimbi engqukuva engqukuva yi-ERW.

Unokukhetha enye yezi ndlela zilandelayo zovavanyo lovavanyo.

a) I-EN 10246-3 ukuya kwinqanaba lokwamkelwa kwe-E4, ngaphandle kokuba umbhobho ojikelezayo/ubuchule bekhoyili yepanekuku abuyi kuvunyelwa;

b) EN 10246-5 kwinqanaba lokwamkelwa F5;

c) EN 10246-8 ukuya kwinqanaba lokwamkelwa kwe-U5.

Amacandelo afakwe kwi-Arc eWelded

Kwimibhobho yentsimbi yecandelo elijikelezileyo yi-LSAW kunye ne-SSAW.

Umthungo odityanisiweyo we-arc entywiliselweyo wamacandelo angaphakathi uya kuvavanywa ngokuhambelana ne-EN 10246-9 ukuya kwinqanaba lokwamkelwa kwe-U4 okanye ngeradiyografi ngokuhambelana ne-EN 10246-10 kunye neklasi yomgangatho we-R2.
