Siziingcali ekunikezeni iinkcukacha ezahlukeneyo zeRound Hollow Structural Steel Pipe, ukuba unayo nayiphi na imfuno, nceda uzive ukhululekile ukunxibelelana nathi, silangazelela ukusebenzisana nawe!
Iipayipi zentsimbi ezidityanisiweyo ze-LSAW zenziwa ikakhulu ngokwenza iipleyiti zentsimbi zibe ziityhubhu kusetyenziswa inkqubo yokubumba ye-JCOE, kulandele ukuwelda kusetyenziswa i-arc engaphantsi kwamanzi enamacala amabini (I-DSAW) iteknoloji yokuwelda, kwaye yagqitywa ngokuhlolwa okuliqela kunye nonyango.
Uyikhetha njani inkqubo yemveliso efanelekileyo? Zithini umahluko kunye neenzuzo zombhobho wentsimbi engenamthungo, i-LSAW, i-arc welding engaphantsi komhlaba, kunye ne-arc welding engaphantsi komhlaba? Kwaye bungakanani ubungakanani benkqubo nganye? Ungacofa ikhonkco elilandelayo ukuze ulibone.
Imigangatho JR,J0, J2 kunye ne-K2 -ishushu igqityiwe;
Iimpawu u-N kunye no-NL - zenziwe zaqhelekileyo. Eziqhelekileyo ziquka ezigoqwe ngendlela eqhelekileyo.

Iimpawu zoomatshini ze-BS EN 10210 ziquka amandla okuvelisa, amandla okutsalwa, ukunwebeka, kunye neempawu zokuchaphazeleka.
Iindawo ezingenanto mazibe nomphezulu ogudileyo ohambelana nendlela yokwenziwa esetyenzisiweyo; amaqhuma, imingxunya, okanye imingxunya emide enganzulu evela kwinkqubo yokwenziwa iyavumeleka, ukuba nje ubukhulu buvumelekile.
EN 10210 Imiphezulu yemibhobho yentsimbi ifanelekile kwi-hot dip galvanizing.
I-EN 10210 ayifuni uvavanyo loxinzelelo lwe-hydrostatic kwimibhobho yentsimbi.
Oku kungenxa yokuba iimveliso ezisemgangathweni ze-EN 10210 zisetyenziselwa ikakhulu iinjongo zokwakha hayi iinkqubo zemibhobho ezifuna ukucinezelwa.
Ukuba kufuneka uvavanyo loxinzelelo lwe-hydrostatic, kunokwenziwa ireferensi kwimigangatho ye-EN 10216 (iityhubhu zentsimbi ezingenamthungo) okanye i-EN 10217 (iityhubhu zentsimbi eziweldiweyo).
Akukho mfuneko inyanzelekileyo kumgangatho wokwenza i-NDT kwimibhobho yentsimbi engenanto.
Ukuba i-NDT yenziwa kwimibhobho yentsimbi edityanisiweyo, ezi mfuno zilandelayo zingabhekiswa kuzo.
Amacandelo aWelded ombane
Kwimibhobho yentsimbi ejikeleze icandelo elingenanto yi-ERW.
Ungakhetha enye yeendlela zovavanyo ezilandelayo zokuvavanya.
a) EN 10246-3 ukuya kwinqanaba lokwamkelwa E4, ngaphandle kokuba indlela yokujikeleza ityhubhu/i-pancake coil ayivumelekanga;
