Esivame ukukubona empilweni kufanele kube amapayipi ensimbi angenamthungo, amapayipi ensimbi anomthungo oqondile kanye namapayipi ashiselwe athandelene.Umhleli olandelayo uthatha kafushane ukuthi uqonde indlela yokuhlukanisa phakathi kwepayipi lensimbi yomthungo oqondile kanye nepayipi lensimbi engenamthungo, futhi ubone ukuthi yini umehluko phakathi kwakho kokubili!

1. Ngaphansi kwezimo ezijwayelekile, izilinganiso zamapayipi ensimbi eqondile esihlangana nawo wonke alungisiwe.Okuvame kakhulu amamitha ayisithupha, amamitha ayisishiyagalolunye namamitha ayishumi nambili.Ngokuyinhloko, ubukhulu bepayipi lensimbi lenziwa ngokuvumelana nezidingo zamakhasimende.Nokho, amapayipi ensimbi angenamthungo awavamile ukuba nosayizi ongashintshi.Kungani?Ngoba uma ipayipi yensimbi engenamthungo yenziwa usayizi ongaguquki, izokwandisa izindleko, futhi intengo izoba phezulu ngokwemvelo.Ngokuyisisekelo, amakhasimende amaningi awakwazi ukukwamukela ngaphansi kwezimo ezijwayelekile.

2. Singabona futhi esigabeni esiphambanayo kuzo zombili iziphetho zepayipi.Uma kukhona ukugqwala ohlangothini olungenhla, lusule futhi ubuke futhi.Uma ubhekisisa, uzothola iminonjana ye-welding ohlangothini olungenhla.

①Ukuhlolwa kwekhwalithi nokwamukelwa kwamapayipi ensimbi othungelwano oluqondile konke kuyahlolwa futhi kwamukelwe umnyango wokugada ikhwalithi womphakeli.

②Umphakeli udinga ukuqinisekisa ukuthi ipayipi lensimbi lomthungo oqondile elethiwe lihlangabezana nezimfuneko zezinga lomkhiqizo elihambisanayo.Umthengi unelungelo lokuhlola nokwamukela ngokuvumelana namazinga omkhiqizo ahambisanayo.Uma ingafaneleki, ngeke iphasiswe.

③Izinto zokuhlola, ubuningi besampula nezindlela zokuhlola zamapayipi ensimbi yomthungo oqondile zidinga ukuhlangabezana nezimfuneko zezindinganiso ezihambisanayo zomkhiqizo.Ngemva kwemvume yomthengi, amapayipi ensimbi angenamthungo agoqelwe ngokushisayo angathathwa ngamaqoqo ngokusekelwe kuhlu lwezimpande ezigoqiwe.

④Emiphumeleni yokuhlolwa yamapayipi ensimbi yomthungo oqondile, lapho elinye lawo lingahlangabezani nezidingo zezinga lomkhiqizo, kuyadingeka ukuthi ukhethe ngokushesha lawo angahlangabezani nezidingo, futhi ngokushesha uthathe iqoqo elifanayo lamasampula afanayo. iqoqo lamapayipi ensimbi omthungo oqondile ukuze kuphindwe kabili izinto ezingafanelekile ukuze zihlolwe.Uma umphumela wokuhlolwa kabusha ungafaneleki, le nqwaba yamapayipi ensimbi yomthungo oqondile ayikwazi ukulethwa.

⑤Uma kungekho mithetho ekhethekile esilinganisweni somkhiqizo, ukwamukelwa kufanele kwenziwe ngokuvumelana nokwakheka kwamakhemikhali wepayipi lensimbi lomthungo oqondile ngokuya ngokusungulwa kokuncibilika.Lokhu futhi kungenye yezindlela ezingahlukaniswa.

3. Ipayipi lensimbi lomthungo oqondile yipayipi lensimbi eline-weld eyodwa kuphela ye-longitudinal.Ngokwenqubo, ingahlukaniswa ngamapayipi ensimbi e-LSAW namapayipi ensimbi e-LSAW.Amapayipi ensimbi omthungo oqondile amapayipi ensimbi amashisela awo ahambisana nesiqondiso sobude sepayipi lensimbi.

①Ipayipi lensimbi engenamthungo linendawo ephambanayo engenalutho, futhi umsebenzi walo usetshenziselwa ikakhulukazi amapayipi athutha uketshezi, njengamapayipi ahambisa uwoyela, igesi yemvelo, igesi nezinto ezithile eziqinile.

②Ngokokubuka kwesakhiwo, umehluko awumkhulu kakhulu.Amapayipi ensimbi omthungo oqondile awanayo i-seamless.I-centroid yepayipi elishiselwe kungenzeka ingabi phakathi.Ngakho-ke, lapho sisisebenzisa njengelungu lokucindezela ngesikhathi sokwakha, kufanele sinake kakhulu ama-welds wepayipi ashiselwe.

③Ipayipi lensimbi elingenamthungo (ipayipi lensimbi le-A53) linqunyelwe ubuchwepheshe bokucubungula, futhi ukushuba kodonga lwepayipi lensimbi ngeke kube mncane kakhulu.Umehluko omkhulu phakathi kwamapayipi angenamthungo namapayipi ashiselwe ukuthi asetshenziselwa ukudlulisa igesi enomfutho noma uketshezi.
