Nasi isingeniso esinemininingwane yeIpayipi lensimbi le-APIkuhlanganisa izakhiwo zomzimba.Ipayipi lensimbi le-API embonini yamapayipi ensimbi linenani elizinzile lika-42% ~ 42% eminyakeni yamuva.Futhi ipayipi elishiselwe linomkhuba okhulayo.Amapayipi ensimbi e-API kanye nepayipi lensimbi elishiselwe ukuthembeka kwezinto zokwakha futhi ukuguquguquka kwazo okuhlukahlukene kunamandla, ikakhulukazi ukuzivumelanisa nodonga oluwugqinsi kanye nokukhiqizwa kwensimbi ye-alloy.Inkinga enkulu ukutshalwa kwezimali okuphezulu, izindleko eziphakeme, inqubo yokukhiqiza eyinkimbinkimbi, ukushuba kwezindonga nokubekezelela ukushisa.Ipayipi yensimbi yesakhiwo empeleni ingumkhiqizo ojulile wokucubungula weshidi.Ngezimo zenani elifanayo, ipayipi le-API lithuthukisa ukuncintisana kwemakethe ngenxa yokuthembeka kwalo.Njengoba ukuthuthukiswa okungapheli kwekhwalithi ye-steel plate kanye nokukhushulwa kwezinga lobuchwepheshe bamapayipi ashiselwe ezinye izingxenye zemishini yamapayipi e-API ziqala ukungena emakethe.Kodwa kungenzeka kuthathelwe indawo amapayipi ashiselwe futhi lokhu kuyindawo elinganiselwe kakhulu.

Ipayipi lensimbi le-API liyipayipi lensimbi elihlanganisiwe elingenamthungo elenza ikhoyili yensimbi ibe yindilinga eyindilinga ngomshini wokushisela imvamisa ephezulu kanye nokucaciswa okuthile kokushisela.Futhi izoba nobuchwepheshe obuhle bokushisela.Lapho abantu beshisela ipayipi lensimbi le-API, ukwakheka kwalo kungaba yindilinga, isikwele noma okungabafokazi.Futhi kungaba ukukhetha kwe-steel tube okuncike ekugibeni kokulinganisa ngemuva kokushisela.I-API steel pipe welding technology ilula.Ngobuchwepheshe obufanele bokukhiqiza nokucubungula, singaqinisekisa ukuthi bungaba nendima ebalulekile kanye nenani elisetshenziswayo.Ukwakhiwa kwamapayipi e-API kudinga izinga eliphezulu lobuchwepheshe kanye nezidingo.Ngakho-ke, uma ungenawo amandla athile, ngeke ukwazi ukukhiqiza amapayipi e-API ekhwalithi afanelekile.

Inqubo yokuginqika okushisayo iyindlela eyinhloko yokukhiqiza yamapayipi ensimbi e-API afinyelela ku-80% wokukhiqizwa kwamapayipi ensimbi athambile angenamthungo.Ipayipi lensimbi elishiselwe kanye nepayipi lensimbi elimnyama nakho kuyatholakala.Ngaphandle kwezinga lobuchwepheshe lomshini wokugaya ngokwawo, ukuhlukahluka kanye nekhwalithi yezinga leyunithi yokukhiqiza, ngezinga elikhulu, kuzovinjelwa ukuncibilika nokusakazwa okuqhubekayo.Ngakho inqubo ethuthukisiwe yokuncibilika iwukuqedela ukucutshungulwa kwamapayipi.Amabhizinisi e-API adumile emhlabeni wonke ngokuvamile angamapayipi ensimbi aphelele noma izinkampani zamashubhu ezingamabhizinisi ensimbi nensimbi.Labo abathembele ekukhiqizweni kwepayipi le-API billet kunzima ukuma emqhudelwaneni oshubile wemakethe ngezikhundla.Kusetshenziswa isithando somlilo se-arc noma ukuncibilika kwe-converter- Ukucwenga i-LF ngaphandle kwesithando somlilo- I-VD vacuum processing- ukuvikela okugcwele kokuthululwa kwe-tube- okuqhubekayo kokusakazwa komshini we-billet oyindilinga, kuyinqubo yanamuhla yokukhiqiza ipayipi lensimbi ye-API ethuthukisiwe.

Ukusebenzisa le nqubo engenhla kungakhiqiza ipayipi elikhethekile likawoyela, ishubhu ye-boiler yomfutho ophezulu, ishubhu ye-alloy ephansi, njll. Okokusebenza kokuncibilikisa, isithando somlilo se-arc kagesi noma umthamo wokuguqula akufanele ube ngaphansi kwama-70t.Ukuze udale izimo zokucwengwa kwe-ladle, kufanele sinake indlela yokuthola ku-inthanethi yesistimu yokulawula eqhubekayo nezenzakalelayo efakwe isistimu yokuhlola ethuthukisiwe.Indawo yepayipi likawoyela kanye nolayini wokukhiqiza amashubhu ka-boiler onengcindezi ephezulu kufanele ifakwe izinga eliphezulu lokwelapha ukushisa kanye nesistimu yomshini.
