1. Isimiso sokukhiqiza ipayipi elingenamthungo
Umgomo wokukhiqiza weipayipi elingenamthungoiwukucubungula i-billet yensimbi ibe yisimo se-tubular ngaphansi kwezimo zokushisa okuphezulu kanye nokucindezela okuphezulu, ukuze kutholakale ipayipi elingenamthungo ngaphandle kwamaphutha okushisela. Inqubo yayo eyinhloko yokukhiqiza ifaka phakathi ukudweba okubandayo, ukugoqa okushisayo, ukugoqa okubandayo, ukubumba, ukukhipha okushisayo kanye nezinye izindlela. Ngesikhathi senqubo yokukhiqiza, ubuso bangaphakathi nangaphandle bepayipi elingenamthungo buba bushelelezi futhi bufane ngenxa yethonya lokushisa okuphezulu kanye nokucindezela okuphezulu, ngaleyo ndlela kuqinisekiswe amandla ayo aphezulu kanye nokumelana nokugqwala, kanye nokuqinisekisa ukuthi ngeke ivuze uma isetshenziswa.
Kuyo yonke inqubo yokukhiqiza, inqubo yokudweba okubandayo iyingxenye ebaluleke kakhulu enqubweni yokukhiqiza ipayipi elingenamthungo. Ukudweba okubandayo kuyinqubo yokusebenzisa umshini wokudweba obandayo ukuze uqhubeke nokucubungula ipayipi lensimbi elingamthungo libe ipayipi elingenamthungo. Ipayipi lensimbi elingamthungo lidonswa kancane kancane ngumshini wokudweba obandayo kuze kube yilapho ubukhulu bodonga nobubanzi obudingekayo yipayipi lensimbi bufinyelelwa. Inqubo yokudweba okubandayo yenza ubuso bangaphakathi nangaphandle bepayipi lensimbi elingenamthungo bube buthambile, futhi ithuthukise amandla nokuqina kwepayipi lensimbi.
2. Ububanzi bokusetshenziswa kwepayipi elingenamthungo
Amapayipi angenamthungo asetshenziswa kabanzi embonini kaphethiloli, amakhemikhali, imishini, amakhemikhali kaphethiloli kanye neminye imboni, futhi izimo zokusetshenziswa kwawo zinezici zamandla aphezulu, izinga lokushisa eliphezulu, umfutho ophezulu, kanye nokumelana nokugqwala. Isibonelo, emkhakheni wokukhishwa kukawoyela negesi yemvelo, amapayipi angenamthungo asetshenziselwa ukuthutha uwoyela, igesi namanzi; embonini yamakhemikhali, amapayipi angenamthungo asetshenziswa kabanzi ezimweni ezibalulekile njengemipayipi enomfutho ophezulu kanye nemishini yamakhemikhali.
Izinhlobo ezahlukene zamapayipi angenamthungo zinezici zazo kanye nezimo zokusetshenziswa, kufaka phakathi amapayipi ensimbi ajwayelekile angenamthungo,amapayipi ensimbi angenamthungo aphansi, amapayipi angenamthungo aphezulu e-alloy, njll. Amapayipi ensimbi ajwayelekile angenamthungo afanelekela imicimbi evamile futhi asetshenziswa kabanzi emikhakheni yemishini, ukwakha imikhumbi, amakhemikhali kanye nezimboni ze-petrochemical; amapayipi ensimbi angenamthungo angaphansi kwe-alloy afanelekela izimo zokusebenza ezikhethekile njengokucindezela okuphezulu, izinga lokushisa eliphezulu, izinga lokushisa eliphansi kanye nokumelana nokugqwala okunamandla; amapayipi angenamthungo angaphansi kwe-alloy ephezulu Ifanelekela izindawo ezikhethekile ezinokushisa okuphezulu, ingcindezi ephezulu, ukugqwala okunamandla kanye nokumelana nokuguguleka okuphezulu.
Ngokuvamile, amapayipi angenamthungo asetshenziswa kabanzi emnothweni kazwelonke, futhi izinzuzo zawo zibonakala kakhulu emandleni awo aphezulu, ukumelana nokugqwala, ukumelana nokushisa okuphezulu, njll. Ngesikhathi esifanayo, izinqubo zawo zokukhiqiza nazo ziyinkimbinkimbi kakhulu, zidinga izinga eliphezulu lobuchwepheshe kanye nokuqongelela ulwazi lokukhiqiza.
