Insimbi Engagqwali 316Ti 1.4571
Leli shidi ledatha lisebenza kunsimbi engagqwali engu-316Ti / 1.4571 ishidi eligoqiwe elishisayo nelibandayo, imikhiqizo eseqediwe kancane, izinsimbi nezinduku, izintambo kanye nezingxenye kanye nasemashubhuni angenamthungo nashikelwe ngezinjongo zokucindezela.
Isicelo
insimbi engagqwali 316TI coiled tube / capillary tube
I-encasement yokwakha, iminyango, amafasitela nezikhali, amamojula angasogwini, isitsha namashubhu amathangi amakhemikhali, indawo yokugcina impahla kanye nokuthuthwa komhlaba kwamakhemikhali, ukudla neziphuzo, ikhemisi, i-synthetic fiber, izitshalo zephepha nezindwangu kanye nemikhumbi yokucindezela.Ngenxa ye-Ti-alloy, ukumelana nokugqwala kwe-intergranular kuqinisekisiwe ngemuva kokushisela.

Iyacubungula / Welding
Izinqubo zokushisela ezijwayelekile zaleli banga lensimbi yilezi:
- I-TIG-Welding
- I-MAG-Welding Solid Wire
- I-Arc Welding (E)
- I-Laser Beam Welding
- I-Summerged Arc Welding (SAW)
Lapho ukhetha insimbi yokugcwalisa, ukucindezeleka kokugqwala kufanele kubhekwe, futhi.Ukusetshenziswa kwensimbi ephezulu ye-alloyed filler kungadingeka ngenxa yesakhiwo sensimbi ye-weld metal.A preheating akudingekile kule steel.Ukwelashwa kokushisa ngemva kokushisela ngokuvamile akusetshenziswa.Izinsimbi ze-Austenitic zine-30% kuphela ye-thermal conductivity yezinsimbi ezingenalo i-alloyed.Iphoyinti lazo lokuhlanganisa liphansi kunalelo lezinsimbi ezingafakwanga i-alloyed ngakho-ke izinsimbi ze-austenitic kufanele zishiselwe ngokufaka ukushisa okuphansi kunezinsimbi ezifakwe i-alloyed.Ukuze ugweme ukushisa ngokweqile noma ukushiswa kwamashidi amancane, isivinini sokushisela kufanele sisetshenziswe.Amapuleti asekela ithusi okwenqatshwa kokushisa okusheshayo ayasebenza, kanti, ukuze kugwenywe ukuqhekeka kwensimbi ye-solder, akuvunyelwe ukufaka phezulu-fuse ipuleti le-backup plate.Le nsimbi ine-coefficient ephezulu kakhulu yokunwetshwa okushisayo njengensimbi engafakwanga.Ngokuphathelene ne-conductivity yokushisa embi kakhulu, ukuhlanekezela okukhulu kufanele kulindelwe.Lapho Welding 1.4571 zonke izinqubo, ezisebenza ngokumelene lokhu ukuhlanekezela (isb. back-step ukulandelana Welding, Welding ngokushintshana ezinhlangothini ezihlukene nge double-V butt weld, isabelo amawelda ezimbili lapho izingxenye zinkulu ngokufanele) kufanele ihlonishwe ngokuphawulekayo.Ngobukhulu bomkhiqizo obungaphezu kuka-12mm i-double-V butt weld kufanele ikhethwe esikhundleni se-single-V butt weld.I-angle ehlanganisiwe kufanele ibe ngu-60 ° - 70 °, uma usebenzisa i-MIG-welding cishe 50 ° kwanele.Ukuqoqwa kwama-weld seams kufanele kugwenywe.Ama-tack weld kufanele ananyathiselwe amabanga amafushane ukusuka komunye nomunye (amafushane kakhulu kunalawo ama-non-alloyed steels), ukuze kuvinjwe ukuguga okuqinile, ukushwabana noma ama-weld ama-flashing.Amatheki kufanele agaywe kamuva noma okungenani angabi nemifantu ye-crater.1.4571 ngokuphathelene nensimbi ye-austenitic weld kanye nokokufaka kokushisa okuphezulu kakhulu ukulutheka ukwenza imifantu yokushisa kukhona.umlutha wemifantu yokushisa ungavaleka, uma insimbi ye-weld ifaka okuqukethwe okuphansi kwe-ferrite (delta ferrite).Okuqukethwe kwe-ferrite kufika ku-10% kunomthelela omuhle futhi akuthinti ukumelana nokugqwala ngokuvamile.Isendlalelo esincanyana kakhulu ngangokunokwenzeka kufanele sishiselwe (isu lobuhlalu obuqinile) ngoba isivinini sokupholisa esiphezulu sehlisa ukuluthwa kwemifantu eshisayo.Ukupholisa okusheshayo okungcono kakhulu kufanele kukhuthazwe ngenkathi kushiselwa futhi, ukugwema ubungozi bokugqwala kwe-intergranular kanye ne-embrittlement.I-1.4571 ifaneleka kakhulu i-laser beam welding (i-weldability A ngokuhambisana ne-DVS bulletin 3203, ingxenye 3).Ngobubanzi begroove yokushisela encane kuno-0.3mm ngokulandelana, ukujiya komkhiqizo ongu-0.1mm ukusetshenziswa kwezinsimbi zokugcwalisa akudingekile.Ngemisele emikhulu yokushisela insimbi efanayo ingasetshenziswa.Ngokugwema i-oxidation ngengaphezulu lomthungo ngesikhathi sokushisela nge-laser beam ngokushisela okusebenzayo kwe-backhand, isb. I-Helium njengegesi engasebenzi, umthungo wokushisela umelana nokugqwala njengensimbi eyisisekelo.Ingozi eshisayo yokuqhuma kwe-welding seam ayikho, lapho ukhetha inqubo esebenzayo.I-1.4571 ibuye ilungele ukusika i-laser beam fusion nge-nitrogen noma ukusika ilangabi nge-oxygen.Amaphethelo asikiwe anezindawo ezincane ezithintekile ekushiseni futhi ngokuvamile awanayo imifantu emincane futhi ngenxa yalokho ayakheka kahle.Ngenkathi kukhethwa inqubo esebenzayo imiphetho ye-fusion cut ingaguqulwa ngokuqondile.Ikakhulukazi, zingafakwa ezishiselwe ngaphandle kokulungiselela okwengeziwe.Ngenkathi kusetshenzwa kuphela amathuluzi angenasici njengamabhulashi ensimbi, okokukhetha umoya nokunye kuvunyelwe, ukuze kungafaki engcupheni i-passivation.Kufanele kunganakwa ukumaka ngaphakathi kwendawo yokuthungela ngamabhawudi e-oleigerous noma izinga lokushisa elibonisa amakhrayoni.Ukumelana nokugqwala okuphezulu kwale nsimbi engagqwali kusekelwe ekwakhekeni kwe-homogeneous, ungqimba lwe-compact passive ebusweni.Imibala ye-annealing, izikali, izinsalela ze-slag, i-tramp iron, ama-spatter nokunye okunjalo kufanele kususwe, ukuze kungabhubhisi ungqimba lwe-passive.Ukuze kuhlanzwe indawo engaphezulu izinqubo zokuxubha, ukugaya, ukukha noma ukuqhumisa (isihlabathi se-silica esingenansimbi noma ama-glass sphere) angasetshenziswa.Ukuxubha amabhulashi ensimbi kuphela angasetshenziswa.Ukuqoqwa kwendawo yomthungo ebhulashiwe ngaphambili kwenziwa ngokucwiliswa nokufafaza, noma kunjalo, kuvame ukunamathela ama-pickle noma izixazululo.Ngemuva kokutshala, ukugeza ngokucophelela ngamanzi kufanele kwenziwe.
Phawula
Esimeni sokucisha impahla ingaba yimagnetizable kancane.Ngokukhula kwamakhaza okwenza i-magnetizability iyanda.
Inothi elibalulekile
Ulwazi olunikezwe kuleli phepha ledatha mayelana nesimo noma ukusebenziseka kwezinto ngokulandelana imikhiqizo ayisona isiqinisekiso sezakhiwo zayo, kodwa yenza njengencazelo.Ulwazi, esilunikeza ukuze uthole iseluleko, luthobela ulwazi lomkhiqizi kanye nolwethu.Asikwazi ukunikeza iwaranti ngemiphumela yokucubungula nokusebenzisa imikhiqizo.
