Amapayipi ensimbi angenamthungo ambozwa ngensimbi eyindilinga yonke, kanti amapayipi ensimbi angenazo izingcezu zokushisela ebusweni abizwa ngokuthi amapayipi ensimbi angenamthungo. Ngokwendlela yokukhiqiza, amapayipi ensimbi angenamthungo angahlukaniswa ngamapayipi ensimbi angenamthungo ashisayo, amapayipi ensimbi angenamthungo abandayo, amapayipi ensimbi angenamthungo adonswayo abandayo, amapayipi ensimbi angenamthungo akhishwe ngaphandle, kanye namapayipi aphezulu. Ngokwesimo sesigaba esinqamulelayo, amapayipi ensimbi angenamthungo ahlukaniswe ngezinhlobo ezimbili: ayindilinga kanye nanobunjwa obukhethekile. Amapayipi anobunjwa obukhethekile afaka phakathi amapayipi ayisikwele, aqandayo, angunxantathu, ayisithupha, imbewu ye-melon, inkanyezi, kanye namapayipi anezinti. Ububanzi obukhulu bungu-22000mm kanti ububanzi obuncane bungu-4mm. Ngokwezinhloso ezahlukene, kunemapayipi ensimbi angenamthungo aqinile kanye namapayipi ensimbi angenamthungo aqinile. Amapayipi ensimbi angenamthungo asetshenziswa kakhulu njengamapayipi okubhoboza i-petroleum geological, amapayipi okuqhekeka embonini ye-petrochemical, amapayipi e-boiler, amapayipi okuthwala, kanye namapayipi ensimbi ahlelekile anembayo kakhulu ezimotweni, ogandaganda, kanye nezindiza.
Amapayipi ensimbi angenamthungo asetshenziswa kabanzi.
1. Amapayipi ensimbi angenamthungo asetshenziswa kabanzi aqhutshwa yinsimbi evamile yesakhiwo sekhabhoni, insimbi yesakhiwo ene-alloy ephansi noma insimbi yesakhiwo ene-alloy, enomkhiqizo omkhulu kunayo yonke, futhi asetshenziswa kakhulu njengamapayipi noma izingxenye zesakhiwo zokuhambisa uketshezi.
2. Ngokwezinhloso ezahlukene, inganikezwa ngezigaba ezintathu:
a. Ukuhlinzeka ngokwesakhiwo samakhemikhali kanye nezakhiwo zemishini;
b. Ngokusho kokusebenza komshini;
c. Ngokuya ngokuhlolwa komfutho wamanzi. Amapayipi ensimbi ahlinzekwa ngokwezigaba a no-b. uma esetshenziselwa ukumelana nomfutho wamanzi, nawo kufanele ahlolwe nge-hydraulic.
3. Amapayipi angenamthungo anezinjongo ezikhethekile ahlanganisa amapayipi angenamthungo ama-boiler, amandla amakhemikhali kanye nogesi, amapayipi ensimbi angenamthungo e-geology, kanye namapayipi angenamthungo e-petroleum.
Amapayipi ensimbi angenamthungo anengxenye engenalutho futhi asetshenziswa ngobuningi njengepayipi lokuthutha uketshezi, njengepayipi lokuthutha uwoyela, igesi yemvelo, igesi, amanzi kanye nezinto ezithile eziqinile. Uma kuqhathaniswa nensimbi eqinile njengensimbi eyindilinga, ipayipi lensimbi lilula ngamandla okugoba kanye nokugoba futhi liyinsimbi yengxenye engabizi. Lisetshenziswa kakhulu ekwenziweni kwezingxenye zesakhiwo nezingxenye zemishini, njengepayipi lokubhoboza uwoyela, imiphini yokudlulisa izimoto, ozimele bamabhayisikili, kanye ne-scaffolding yensimbi esetshenziswa ekwakheni. Amapayipi ensimbi asetshenziselwa ukwenza izingxenye zendandatho, ezingathuthukisa ukusetshenziswa kwezinto, zenze kube lula izinqubo zokukhiqiza, futhi zonge izinto kanye nokucubungula. Amahora okusebenza.
Kunezinqubo ezimbili eziyinhloko zokukhiqiza zamapayipi ensimbi angenamthungo (ukugoqa okubandayo kanye nokugoqa okushisayo):
①Inqubo yokukhiqiza eyinhloko ye-cccccccc (△inqubo yokuhlola eyinhloko):
Ukulungiswa nokuhlolwa kwe-tube billet△→ukushisa kwe-tube billet→ukubhoboza→ukugingqika kwe-tube→ukufudumala kabusha kwe-pipe→ububanzi obuqinile (obuncishisiwe)→ukwelashwa kokushisa△→ukulungiswa kwe-tube okuqediwe→ukuqeda→ukuhlolwa△(okungonakalisi, okungokomzimba nokungokwekhemikhali, ukuhlolwa kwebhentshi)→kugcinweni
②Inqubo eyinhloko yokukhiqiza ipayipi lensimbi elingenamthungo eligoqwe ngokubandayo:
Ukulungiswa okungenalutho → ukukhahlela nokugcoba → ukugoqa okubandayo (ukudweba) → ukwelashwa ngokushisa → ukuqondisa → ukuqeda → ukuhlolwa → isitoreji
