Thola izimfihlo zamapayipi ashiselwe aqinile

Ensimbi yesimanje yezimboni, into eyodwa igqama njengomgogodla wokwakhiwa kobunjiniyela ngenxa yezakhiwo zayo eziphelele—amapayipi ensimbi e-Q345, anikeza amandla alinganayo, ukuqina, nokusebenza.

 

I-Q345 iyinsimbi ye-alloy ephansi, eyayaziwa ngokuthi i-16Mn. I-"Q" ekuqokweni kwayo imele amandla esivuno, kuyilapho "345" ikhombisa amandla amancane okukhiqiza angu-345 MPa ekamelweni lokushisa. Ihambisana nezinga le-GB/T 1591-2008, ithola ukusetshenziswa okubanzi kumabhuloho, izakhiwo, izimoto, imikhumbi, imikhumbi yokucindezela, kanye namaphrojekthi wobunjiniyela be-cryogenic. Ivamise ukunikezwa ezimeni ezishisiwe noma ezijwayelekile.

 

Ukuhambisana ekusebenzeni kokucubungula kungenye inzuzo enkulu yamapayipi ensimbi e-Q345. Okuqukethwe kwayo kwekhabhoni ephansi (imvamisa engu-≤0.20%) kanye nokwakheka kwe-alloy okulungiselelwe kuqinisekisa ukushisela okuhle kakhulu. Ukuthi kusetshenziswa ukushisela i-arc yensimbi eyenziwe ngesandla, i-arc engaphansi kwamanzi, noma i-gas shielded welding, amajoyinti ashiselwe ezinzile futhi athembekile angafinyelelwa, ukuhlangabezana nezidingo eziyinkimbinkimbi zokwakha endaweni. Ukwengeza, izindawo zayo zokusebenza ezibandayo nezishisayo zivumela ukwenziwa kwezinto ezimise okwehlukene ngezinqubo ezifana nokugoqa, ukugoba, nokugxiviza, okuhlanganisa imiklamo ehlukahlukene yobunjiniyela.

 

I-Landscape Yesicelo: Kusukela Ezakhiweni Eziyingqopha-mlando kuya Kungqalasizinda Yamandla, amapayipi ensimbi e-Q345 angena kuzo zonke izingxenye zemboni yesimanje. Ekwakheni nasekuthuthukisweni kwamabhuloho, asekela izinhlaka zezakhiwo eziphakeme futhi asebenza njengezisekelo eziyinhloko zamabhuloho awela imifula, asebenzise amandla awo aphezulu ukuze anciphise isisindo sesakhiwo ngenkathi emelana nokuzamazama komhlaba kanye nemithwalo yomoya ephezulu ngokusebenzisa ukuqina okuthuthukisiwe. Imishini yobunjiniyela namafreyimu, amashafu okushayela izimoto ezisindayo, namakholomu ombhede wethuluzi lomshini konke kudinga izinto ezihlanganisa amandla nokumelana nokukhathala. Ngokudweba okubandayo nezinqubo zokwandisa okushisayo, amapayipi ensimbi e-Q345 ahlangabezana ngokunembile nezidingo zemishini yezingxenye ezihlukene, andisa isikhathi sokuphila kwemishini. Ekusetshenzisweni kwamandla namapayipi—njengamapayipi asakaza uwoyela negesi, amanzi asemadolobheni nenethiwekhi yokushisisa, namapayipi okushisa aphezulu akubhayela bemishini kagesi—izinto ezisetshenziswayo kumelwe zimelane kokubili ukucindezela kwangaphakathi nokugqwala kwangaphandle. Amapayipi ensimbi e-Q345, aphathwe ngokuvikela ukugqwala kwendawo (isb., ukudweba, ukwenza uthayela), aqinisekisa ukusebenza okuzinzile kwesikhathi eside endaweni enomswakama, enothuli, noma egqwala kancane, evikela ukuthuthwa kwamandla okuphephile nokusebenza kahle.

 

Ukuqinisekiswa Kwenqubo:Ukuzibophezela Kwekhwalithi kusuka ku-Ingot kuya Emkhiqizweni Oqediwe Ukwakhiwa kwamapayipi ensimbi e-premium Q345 kuncike ekulawuleni inqubo yokukhiqiza okunembayo. Amapayipi angenamthungo abhobozwa, ayagingqika, futhi alinganiswe ukuze kuqinisekiswe ukujiya kodonga olufanayo nokunemba kobukhulu. Amapayipi ashiselwe akhiwa nge-high-frequency noma i-arc welding engaphansi kwamanzi, elandelwa ukuhlolwa okungabhubhisi nokwelashwa okushisa okunciphisa ukucindezeleka ukuze kuqedwe izingozi ezingase ziqhekeke ngesikhathi sokusetshenziswa. Wonke amapayipi ensimbi e-Q345 ahlolwa kaningi—okuhlanganisa nokuhlolwa okuqinile, ukuhlolwa komthelela, nezilinganiso zokuqina—ukuqinisekisa ukuthotshelwa kokusebenza.

 

Amathrendi Azayo:Umzila Oluhlaza Nokusungulwayo Oqhutshwayo Wokuthuthukisa

Eqhutshwa ukuthuthuka kwezinjongo “zekhabhoni embaxambili” kanye nesidingo esikhulayo sokukhanyisa izimboni, amapayipi ensimbi e-Q345 athuthukela ekusebenzeni kahle okukhulu nasekusimameni kwemvelo. Ngakolunye uhlangothi, ngamasu athuthukisiwe e-microalloying (njengokwengeza izakhi ezifana ne-niobium ne-titanium), isizukulwane esisha samapayipi ensimbi e-Q345 siphinde sinciphise ukusetshenziswa kwe-alloy kuyilapho sigcina amandla, sizuza “okuningi ngokuncane.” Ngakolunye uhlangothi, ukuthuthukiswa kokukhiqiza okuhlakaniphile—kusuka ekuqaphelweni kwesikhathi sangempela kokubunjwa kwensimbi encibilikisiwe kuya ekubikezeleni ukusebenza komkhiqizo oqediwe—kuthuthukisa ukuzinza komkhiqizo kanye nezilinganiso zokukhiqiza ngokulawula kwedijithali ekupheleni kuya ekupheleni.

 
Ezimeni zohlelo lokusebenza, amapayipi ensimbi e-Q345 andela emkhakheni omusha wamandla—izakhiwo zokusekela zemibhoshongo yenjini yomoya, izingxenye ezithwala umthwalo zamarack e-photovoltaic, namapayipi okuthutha nge-hydrogen konke kubeka izimfuno ezintsha zamandla ezinto ezibonakalayo kanye nokumelana nesimo sezulu. Ngokusebenzisa ukusebenza kahle, amapayipi ensimbi e-Q345 kancane kancane aba into ethandwayo kule mikhakha. Kusukela ezindaweni eziphawulekayo zasemadolobheni kuya emihubheni yamandla, kusukela emishinini esindayo kuya kungqalasizinda yomphakathi, amapayipi ensimbi e-Q345 abonisa inani lemboni yensimbi ene-alloy high-strength ngezinzuzo zawo eziyinhloko zamandla aphezulu, ukuqina okuphezulu, kanye nokucutshungulwa kalula. Azimi nje njengobufakazi benqubekelaphambili yezobuchwepheshe ezintweni zensimbi kodwa futhi “njengomgogodla wensimbi” obalulekile wokwakhiwa kobunjiniyela besimanje. Esigabeni sezimboni esizayo, amapayipi ensimbi e-Q345 azoqhubeka nokuphendula izimfuno zezikhathi ngokusungula izinto ezintsha nokuthuthukisa, efaka “amandla ensimbi” kumaphrojekthi amakhulu kakhulu.
