Iipayipi zentsimbi ezingenamthungo zigqobhozwa ngentsimbi ejikelezileyo, kwaye iipayipi zentsimbi ezingenazo ii-welds phezu komhlaba zibizwa ngokuba ziipayipi zentsimbi ezingenamthungo. Ngokwendlela yokuvelisa, iipayipi zentsimbi ezingenamthungo zingahlulwa zibe ziipayipi zentsimbi ezingenamthungo ezigoqwe ngobushushu, iipayipi zentsimbi ezingenamthungo ezigoqwe ngobandayo, iipayipi zentsimbi ezingenamthungo ezitsalwa ngobandayo, iipayipi zentsimbi ezingenamthungo ezikhutshiweyo, kunye neepayipi eziphezulu. Ngokwemilo yecandelo elinqamlezileyo, iipayipi zentsimbi ezingenamthungo zahlulwe zibe ziintlobo ezimbini: ezijikelezileyo nezinemilo ekhethekileyo. Iipayipi ezinomilo ekhethekileyo ziquka isikwere, i-oval, i-triangular, i-hexagonal, imbewu ye-melon, inkwenkwezi, kunye neepayipi ezine-finned. Ububanzi obuphezulu yi-22000mm kwaye ububanzi obuncinci yi-4mm. Ngokweenjongo ezahlukeneyo, kukho iipayipi zentsimbi ezingenamthungo ezigoqwe ngodonga oluqinileyo kunye neepayipi zentsimbi ezingenamthungo ezibhityileyo. Iipayipi zentsimbi ezingenamthungo zisetyenziswa kakhulu njengeepayipi zokubhola ze-petroleum geological, iipayipi zokuqhekeka kushishino lwe-petrochemical, iipayipi ze-boiler, iipayipi zokuthwala, kunye neepayipi zentsimbi ezichanekileyo kakhulu kwiimoto, iitrektara, kunye neenqwelomoya.
Iipayipi zentsimbi ezingenamthungo zisetyenziswa kakhulu.
1. Imibhobho yentsimbi engenamthungo esetyenziselwa iinjongo ngokubanzi iqengqwa ngentsimbi eqhelekileyo yesakhiwo sekhabhoni, intsimbi yesakhiwo ene-alloy ephantsi okanye intsimbi yesakhiwo ene-alloy, enemveliso enkulu, kwaye isetyenziswa kakhulu njengemibhobho okanye iindawo zesakhiwo zokuhambisa ulwelo.
2. Ngokweenjongo ezahlukeneyo, ingafumaneka kwiindidi ezintathu:
a. Ukubonelela ngokwendlela iikhemikhali ezibunjwe ngayo kunye neempawu zoomatshini;
b. Ngokwendlela esebenza ngayo i-mechanical;
c. Ngokwendlela yovavanyo loxinzelelo lwamanzi. Imibhobho yentsimbi enikezelwa ngokweendidi a kunye no-b. ukuba isetyenziselwa ukumelana noxinzelelo lolwelo, nayo iya kuvavanywa nge-hydraulic.
3. Iipayipi ezingenamthungo zenjongo ekhethekileyo ziquka iipayipi ezingenamthungo zeebhoyila, amandla eekhemikhali kunye nombane, iipayipi zentsimbi ezingenamthungo zejoloji, kunye neepayipi ezingenamthungo zepetroliyam.
Iipayipi zentsimbi ezingenamthungo zinecandelo elingenanto kwaye zisetyenziswa ngobuninzi njengeepayipi zokuthutha ulwelo, njengeepayipi zokuthutha ioyile, igesi yendalo, igesi, amanzi kunye nezinto ezithile eziqinileyo. Xa kuthelekiswa nentsimbi eqinileyo efana nentsimbi engqukuva, ipayipi yentsimbi ilula ngamandla okugoba kunye nokujika kwaye yintsimbi yecandelo engabizi kakhulu. Isetyenziswa kakhulu ekwenziweni kweendawo zokwakha kunye neendawo zoomatshini, ezifana neepayipi zokubhola ioyile, imibhobho yokuhambisa imoto, iifreyimu zebhayisekile, kunye ne-scaffolding yentsimbi esetyenziswa ekwakheni. Iipayipi zentsimbi zisetyenziselwa ukwenza iindawo zeringi, ezinokuphucula ukusetyenziswa kwezinto, zenze lula iinkqubo zokuvelisa, kwaye zonge izixhobo kunye nokucubungula. Iiyure zokusebenza.
Kukho iinkqubo ezimbini eziphambili zemveliso yeepayipi zentsimbi ezingenamthungo (ukuqengqeleka okubandayo kunye nokuqengqeleka okushushu):
①Inkqubo ephambili yemveliso ye-cccccccc (△inkqubo ephambili yokuhlolwa):
Ukulungiswa kunye nokuhlolwa kwe-tube billet△→ ukufudumeza i-tube billet→ ukugqobhoza→ ukuqengqeleka kwe-tube→ ukufudumeza kwakhona i-pipe→ ububanzi obuzinzileyo (obuncitshisiweyo)→ unyango lobushushu△→ ukuqiniswa kwe-tube → ukugqitywa → ukuhlolwa△(ukungonakalisi, okubonakalayo kunye nokwekhemikhali, ukuhlolwa kwebhentshi)→ kugcinwe
②Inkqubo ephambili yemveliso yombhobho wentsimbi engenamthungo oqengqelekayo obandayo:
Ukulungiswa okungenanto → ukucola kunye nokuthambisa → ukuqengqeleka okubandayo (ukuzoba) → unyango lobushushu → ukucokisa → ukugqiba → ukuhlolwa → ukugcinwa
