Eminyakeni emihlanu edlule, ukuthambekela kokuthuthukiswa kwepayipi elishiselwe insimbi engagqwali kube kuhle uma kuqhathaniswa.Kungakhathaliseki izinga, ikhwalithi, kanye nobuchwepheshe bokukhiqiza, kube nenqubekelaphambili enkulu uma kuqhathaniswa, ikakhulukazi umkhakha wayo wokufunwa ukhula kancane kancane.Ngaphezu kwalokho, njengoba insimbi engagqwali ashiselwe ipayipi ubuchwepheshe buvuthwa, kancane kancane ungakwazi esikhundleni insimbi engagqwali nekhono amapayipi izicelo eziningi, ezifana: ukushisa exchanger imishini amashubhu, medium and low pressure kubhayela amashubhu, nokunye.

Izici zokukhiqiza zensimbi engagqwali eshiselwe ipayipi: imishini yokukhiqiza ukukhanya, ukutshalwa kwezimali okuphansi, isivinini sokwakha esisheshayo, indlela elula yokushisela, ububanzi bokucaciswa komkhiqizo, ukunemba okuphezulu kwe-dimensional, ukuchezuka kodonga oluncane, ubuso obushelelezi kanye nezinga eliphezulu lesivuno.Endabeni yokukhiqiza ngobuningi, izindleko zamapayipi ashiselwe zingaphansi kuka-20% kunalezo zamapayipi angenamthungo.Eminyakeni yamuva nje, inqubo 'ye-welding-cold rolling' eyamukelwa e-China ukuze kukhiqizwe amashubhu ensimbi engagqwali iwukusebenzisa amakhoyili agoqekile ukuze ahlukanise futhi alolonge ngokuvumelana nemibandela ebekiwe, awashise abe amashubhu ngomshini wokushisela we-argon arc we-multi-gun. , bese kubanda-roll (ukudonsa) ukwenza Izinkomba zokusebenza ze-weld zingafana ngokuyisisekelo nezinto eziyisisekelo, futhi ikhwalithi yomkhiqizo ithuthukiswa kakhulu.Ngakho-ke, izinzuzo zokushintsha amapayipi angenamthungo ensimbi engenasici ngensimbi engagqwali ashiselwe amapayipi aya ngokuya abonakala.

Izinzuzo zokukhiqizwa kwepayipi elishiselwe insimbi engagqwali: Okokuqala, ekukhiqizeni ipayipi elishiselwe insimbi engagqwali, umzimba wepayipi uzocindezelwa ngokulinganayo, bese kuthi ngemuva kokuncibilika okuqinile okuqinile okuku-inthanethi, ubuso buba bushelelezi kakhulu, futhi indawo ebushelelezi akulula ukukala, ngezici zokulwa nokukala.Lokhu kokubili kusiza ekuqedeni ukushisa futhi akudingi ukuhlanzwa njalo, ukonga isikhathi, umzamo kanye nemali.Okwesibili, ipayipi elihlanganisiwe liwumkhiqizo owenziwe ngokujulile wepuleti, futhi inzuzo yayo yobukhulu bodonga obufanayo ayinakulinganiswa.Ngesikhathi esifanayo, ingahle ibe nobukhulu obunqunyelwe, ngokunemba okuphezulu.Okwesithathu, impahla yensimbi engagqwali inezici zokumelana nokugqwala kanye nempilo ende yenkonzo.

Isimo samanje semikhiqizo yamapayipi ensimbi engagqwali ashiselwe: Umthamo wokukhiqiza wepayipi elishiselwe insimbi engagqwali yaseChina alihambisani nesidingo semakethe yasekhaya.Iningi ekhona insimbi engagqwali ashiselwe ipayipi iyunithi imishini inqubo ayiphelele, ezifana ukuntuleka ukwelashwa ukushisa kanye nemishini yokuhlola inthanethi, ukuze umthamo ukukhiqizwa unit Nikeza ukudlala okugcwele, ngokuvamile kungaba kuphela ukukhiqiza amashubhu okuhlobisa jikelele, kanye nemakethe of insimbi engagqwali ehlobisa amashubhu ashiselwe aphakathi nendawo adlula ukunikezwa;amashubhu ashiselwe ezimbonini asezingeni eliphakeme, njengamashubhu emishini yamakhemikhali namashubhu okushintsha ukushisa, angabakhiqizi abambalwa kuphela Angakhiqizwa, kodwa amandla okukhiqiza awanele kakhulu.I-Hangao Tech (SEKO Machinery) Uchungechunge lwe-SZG-JM olunembayo lwensimbi engagqwali ulayini wokukhiqiza wamapayipi ashiselwe uxazulula le nkinga.Wonke ulayini wokukhiqiza uhlanganisa uchungechunge lwezinqubo ezifana nokwenza i-welding, i-internal welding seam leveling, i-welding seam grinding, i-annealing ekhanyayo, nokusika usayizi.Uhlelo oluhlakaniphile lokulawula i-elekthronikhi luqondisa ukusebenza kwengxenye ngayinye, luthuthukise ukusebenza kahle kuyilapho lwehlisa ukusebenza kahle kwamandla.
Ingabe ipayipi elishiselwe lisebenza emshinini wokushintshanisa ukushisa?
1. Amashubhu omkhiqizo asezingeni eliphakeme angenzeka
Ishubhu yokushintshisana ngokushisa iyingxenye ebalulekile yemishini yokushintshisana yokushisa yeshubhu neshubhu, futhi ishubhu yesishintshi sokushisa ngokuvamile ikhethwa ngokuvumelana nengcindezi nendawo yoketshezi.Manje okunye kokungaqondi kahle ekukhetheni amashubhu okushintsha ukushisa emakethe ukuthi amashubhu ashiselwe ensimbi engenasici awakwazi ukusetshenziswa njengamashubhu okushintshanisa ukushisa, kodwa i-GB / 151-1999 ikubeka ngokusobala ukuthi amashubhu ashiselwe ensimbi engagqwali angakhethwa lapho ukucindezela ohlangothini lweshubhu. ingu-≤6.4MPa.Ikakhulukazi manje njengoba inqubo yokukhiqiza amapayipi ensimbi engagqwali ashiselwe manje isivuthiwe kakhulu, ingahlangabezana ngokugcwele nezidingo zamashubhu okushintshanisa ukushisa okujwayelekile, futhi ibonise izinzuzo zayo eziyingqayizivele.
2. Inqubo yokukhiqiza ivuthiwe, ipayipi elihlanganisiwe le-austenitic insimbi engenasici iyoba yisinqumo sokuqala
Njengoba ishubhu lokushintshanisa ukushisa lakha indawo yokudlulisa ukushisa yesishintshi sokushisa, ubukhulu beshubhu yesishintshi sokushisa bunomthelela omkhulu ekudlulisweni kokushisa.Uma usebenzisa amashubhu amancane obubanzi, indawo yokushintshanisa ukushisa ngeyunithi ngayinye yevolumu yomshini wokushisa inkulu, imishini ihlangene, ukusetshenziswa kwensimbi endaweni yokudlulisa ukushisa kweyunithi kuncane, futhi i-coefficient yokudlulisa ukushisa nayo iphakeme.Nakuba kunzima ukwenza, ukusetshenziswa kwamashubhu ashiselwe ensimbi engenasici ye-austenitic njengamashubhu okushintsha ukushisa kungagwema izinkinga ezingenhla.Ngenxa yokuthi amashubhu ashiselwe ensimbi engagqwali ye-austenitic anokumelana nokugqwala okuhle kanye nezindawo ezibushelelezi, futhi inqubo yokukhiqiza isivuthiwe, ngakho-ke amashubhu ashiselwe ensimbi engagqwali austenitic ayinketho yokuqala yamashubhu okushintsha ukushisa.Izinto ezingacutshungulwa yi- I-Hangao Tech (SEKO Machinery) SZG-JM yochungechunge olushiselwe umugqa wokukhiqiza wamapayipi ashiselwe zihlanganisa: insimbi engagqwali, i-austenite, i-ferrite, i-titanium alloy kanye nensimbi yesigaba esikabili, eguquguqukayo kakhulu futhi ingasethwa futhi ilungiswe ngokuvumelana nama-oda wamakhasimende.
