Umbhobho wentsimbi ongenamthungo Ukucaciswa, iMigangatho kunye neBanga.

Imibhobho yentsimbi engenamthungo isetyenziswa ngokubanzi kumashishini ahlukeneyo ukuthutha ulwelo kunye neegesi, kunye nokusetyenziswa kwezakhiwo.Zenziwa ngaphandle kwe-welding okanye i-seams, ezenza zibe namandla kwaye zithembeke ngakumbi.Inkcazo, imigangatho, kunye namabakala eimibhobho yentsimbi engenamthungoinokwahluka ngokuxhomekeke kwiimfuno ezithile zesicelo.Nazi iinkcukacha ezisetyenziswa ngokuqhelekileyo, imigangatho, kunye namabanga emibhobho yentsimbi engenamthungo:

Inkcazo:I-ASTM A106-Inkcazo eMiselweyo yoMbhobho weSimbi weCarbon ongenamthungo kwiNkonzo yoBubushushu obuphezulu

1.Le nkcazo igubungela umbhobho wentsimbi ye-carbon engenamthungo kwizicelo eziphezulu zokushisa.Ibandakanya amabanga ahlukeneyo afana no-A, B, no-C.

Inkcazo:I-ASTM A53-Inkcazo eqhelekileyo yoMbhobho, iNsimbi, iMnyama kunye neHot-Dipped, iZinc-Coated, iWelded kwaye ayinamthungo

1.Olu phawu lugubungela umbhobho wentsimbi ongenamthungo kunye newelding emnyama kunye neshushu-dipped.Ibandakanya amabanga ahlukeneyo afana no-A, B, no-C.

Inkcazo:API 5L- Inkcazo yoMbhobho womgca

I-1.Le nkcazo igubungela umbhobho wensimbi ongenamthungo kunye ne-welded kwizicelo ezahlukeneyo.Ibandakanya amabakala ahlukeneyo njengeAPI 5L iBanga B, X42, X52, X60, X65, njl.

Uchazo:I-ASTM A252-icacisa iimfuno zemibhobho yentsimbi edityanisiweyo kunye nengenamthungo ukuze isetyenziswe kulwakhiwo kunye nolwakhiwo.

1.Inkcazo ye-ASTM A252 ihlanganisa amabakala amathathu eemfumba zemibhobho yensimbi: iBanga loku-1, iBanga lesi-2, kunye neBanga lesi-3. Ibakala ngalinye lineempawu ezahlukeneyo zomatshini, kubandakanywa amandla amancinci okuvelisa kunye namandla amancinci, ukuhlangabezana neemfuno ezithile zeprojekthi.
