Umbhobho weNtsimbi engenamthungo, iMigangatho kunye noHlelo.

Iipayipi zentsimbi ezingenamthungo zisetyenziswa kakhulu kumashishini ahlukeneyo ekuthuthweni kwezinto ezimanzi kunye neegesi, kunye nokusetyenziswa kwezakhiwo. Zenziwa ngaphandle kokuwelda okanye ukuthungwa, nto leyo eyenza zibe namandla kwaye zithembeke ngakumbi. Iinkcukacha, imigangatho, kunye neendidi zeimibhobho yentsimbi engenamthungoingahluka ngokuxhomekeke kwiimfuno ezithile zesicelo. Nazi ezinye zeenkcukacha ezisetyenziswa rhoqo, imigangatho, kunye namanqanaba emibhobho yentsimbi engenamthungo:

Inkcazo:I-ASTM A106-Inkcazo esemgangathweni yePipe yeNtsimbi yeKhabhoni engenamthungo yeNkonzo yoBushushu obuPhezulu

1. Le nkcazelo igubungela umbhobho wentsimbi yekhabhoni engenamthungo kwizicelo zobushushu obuphezulu. Ibandakanya amanqanaba ahlukeneyo afana no-A, B, kunye no-C.

Inkcazo:I-ASTM A53-Iinkcazo ezisemgangathweni zePipe, iSteel, emnyama neshushu, egqunywe ngeZinc, eWelded kwaye engenamthungo

1. Le nkcazelo igubungela umbhobho wentsimbi omnyama noshushu odityaniswe ngaphandle komthungo nowenziwe ngentsimbi. Iquka iintlobo ezahlukeneyo ezifana no-A, B, kunye no-C.

Inkcazo:I-API 5L- Inkcazo yePipe yoMgca

1. Le nkcazelo igubungela umbhobho wentsimbi ongenamthungo nowenziwe ngentsimbi kwizicelo ezahlukeneyo. Ibandakanya amanqanaba ahlukeneyo afanaI-API 5L Ibanga B, X42, X52, X60, X65, njl.

ingcaciso:I-ASTM A252-ichaza iimfuno zeepayipu zentsimbi ezidityanisiweyo nezingenamthungo ezisetyenziselwa ukwakhiwa kunye nokusetyenziswa kwezakhiwo.

1.Inkcazo ye-ASTM A252 igubungela amanqanaba amathathu eepayipu zentsimbi: Ibanga loku-1, iBanga lesi-2, kunye neBanga lesi-3. Ibanga ngalinye lineempawu ezahlukeneyo zoomatshini, kubandakanya amandla amancinci okuvelisa kunye namandla amancinci okutsalwa, ukuhlangabezana neemfuno ezithile zeprojekthi.
