Iyini Ibha Yensimbi Engagqwali engu-316L? Izakhiwo, Amazinga kanye Nezicelo

I-316L Stainless Steel Bar ingenye yezinto ezisetshenziswa kakhulu zebha yensimbi engagqwali ye-austenitic ekucubungulweni kwamakhemikhali, imishini yasolwandle, imishini yokudla, ama-valve, imiphini, izikhonkwane, izingxenye zephampu kanye nezingxenye zomshini wokunemba. Kubathengi bezimboni, imibuzo ebaluleke kakhulu ngokuvamile akuyona nje "iyini ibha yensimbi engagqwali ye-316L," kodwa futhi "yimuphi umthetho osebenzayo," "yisiphi isitifiketi okufanele sihlolwe," kanye nokuthi "ngingaqinisekisa kanjani ukuthi izinto ezinikeziwe ziyi-316L ngempela."

Lesi sihloko sibhalelwe abathengi bobunjiniyela, abathengi bephrojekthi, abahloli bekhwalithi kanye namaqembu okuthola ulwazi abadinga umhlahlandlela osebenzayo wencazelo yebha eyindilinga yensimbi engagqwali engu-316L, ibha eyisicaba, ibha yesikwele noma ibha eyenziwe ngomshini eyenziwe ngokwezifiso. Sihlanganisa ububanzi obujwayelekile, amamaki alinganayo, ukwakheka kwamakhemikhali, izakhiwo zemishini, uhlu lokuhlola isitifiketi, amaphutha okuthenga avamile, izidingo zokuhlola kanye nokukhetha kwesicelo.

Iyini Ibha Yensimbi Engagqwali engu-316L?

Ibha yensimbi engagqwali engu-316L iyibha yensimbi engagqwali ye-austenitic ene-carbon molybdenum ephansi. I-“L” isho i-carbon ephansi, ngokuvamile enokuqukethwe kwe-carbon okungadluli ku-0.03%. Uma iqhathaniswa nensimbi engagqwali ejwayelekile engu-316, i-316L inikeza ukumelana okungcono kokuzwela ngesikhathi sokushisela noma ukuvezwa kokushisa, okwenza ifanele izakhiwo ezishisiwe, imishini yamakhemikhali, izingxenye zasolwandle kanye nezingxenye zomshini ezingagqwali.

Ekuthengeni kwamanye amazwe, ibha yensimbi engagqwali engu-316L ivame ukunikezwa njengebha yensimbi engagqwali engu-UNS S31603, EN 1.4404, X2CrNiMo17-12-2, SUS316L noma i-ASTM A276 / ASTM A479 316L. Ingakhiqizwa njengebha egoqwe ngokushisa, ibha edonswayo ebandayo, ibha ehlutshiwe, ibha ephendukile, ibha egayiwe, ibha epholishiwe noma ibha ehlanganisiwe ngokobubanzi, ukubekezelelana, ukuphela kwendawo kanye nokusetshenziswa kokugcina.

Ukuqeda Okungaphezulu, Ukupakisha Nokukwazi Ukulethwa

Ibha yensimbi engagqwali engu-316L inganikezwa ngezimo ezahlukene zobuso kuye ngokuthi icutshungulwa kanjani kanye nokusetshenziswa kokugcina. Ubuso obumnyama buvame kakhulu kumabha aguqiwe ashisayo, kuyilapho izindawo ezikhanyayo, ezihlutshiwe, eziphendulwe, ezigayiwe noma ezipholishiwe zikhethwa kakhulu ekufakeni, ezingxenyeni zokuhlobisa noma ezingxenyeni ezinembile. Ukuze kuthunyelwe kwamanye amazwe, amabha kufanele apakishwe ukuze kuvinjelwe ukugoba, ukuklwebheka kobuso, umonakalo womswakama kanye nokudideka phakathi kwezinombolo zokushisa.

Izincomo Zokupakisha Zokuthumela Ngaphandle

Ukuze kuthunyelwe kwamanye amazwe, i-SAKY STEEL ingahlinzeka ngokupakisha inqwaba, ukupakisha izikhwama zokhuni, ukugoqa okungangeni manzi, izigqoko zepulasitiki, ukuqinisa imicu yensimbi kanye nezimpawu zokuthumela ezicacile. Kumabha ensimbi angagqwali angu-316L anqunyiwe ubude, inqwaba ngayinye ingafakwa ilebula ngebanga, usayizi, inombolo yokushisa, ubuningi kanye nenombolo ye-oda ukusekela ukwamukelwa nokuhlolwa kwempahla yokugcina impahla.

Imibuzo Evame Ukubuzwa: Ukucaciswa Kwebha Yensimbi Engagqwali engu-316L kanye Nokuhlolwa Kwesitifiketi

1. Yisiphi isitifiketi okufanele ngisicele sebha yensimbi engagqwali engu-316L?

Uma uthenga ezimbonini, abathengi kufanele bacele i-EN 10204 3.1 MTC. Isitifiketi kufanele sibonise ibanga, inombolo yokushisa, izinga elijwayelekile, ukwakheka kwamakhemikhali, izakhiwo zemishini kanye nosayizi womkhiqizo. Kumaphrojekthi abalulekile, ukuhlolwa kwe-PMI kanye nokuhlolwa komuntu wesithathu nakho kungacelwa.

2. Ngingaqinisekisa kanjani ukuthi ibha ingu-316L ngempela?

Hlola i-MTC kuqala, ikakhulukazi amanani e-carbon, i-chromium, i-nickel kanye ne-molybdenum. Bese usebenzisa ukuhlolwa kwe-PMI kumabha wangempela ukuqinisekisa ibanga. Inombolo yokushisa elebula lebha kufanele ifane nenombolo yokushisa eku-MTC.

3. Ingabe i-ASTM A276 iyindinganiso efanele yebha yensimbi engagqwali engu-316L?

I-ASTM A276 ivame ukusetshenziswa emigoqweni nasezimo zensimbi engagqwali. Kodwa-ke, i-ASTM A479 / ASME SA479 ingadingeka ezitsheni zokucindezela, ebhoyileni noma ezinsizeni zesevisi yokushisa okuphezulu. Abathengi kufanele baqinisekise indinganiso yephrojekthi ngaphambi koku-oda.

4. Yikuphi ukuqeda okukhona kwebha yensimbi engagqwali engu-316L?

Ukuphela kwendawo okuvamile kufaka phakathi umhlabathi omnyama, okhanyayo, ocwebezelayo, ohlutshiwe, oguquliwe, ogayiwe kanye nongenasisekelo. Indawo efanele incike ekuvunyelweni komshini, isidingo sokubukeka, ukubekezelelana kanye nokusetshenziswa kokugcina.

5. Ingabe ibha yensimbi engagqwali engu-316L ingasikwa ibe ubude obufanele?

Yebo. Ibha yensimbi engagqwali engu-316L inganikezwa ngobude obujwayelekile noma inqunywe ngobude obufanele. Ngezingcezu ezisikiwe, abathengi kufanele baqinisekise ukubekezelela ubude, ikhwalithi yokusika ekugcineni, indlela yokupakisha kanye nobuningi ngephakheji ngayinye.

Isiphetho

Ibha Yensimbi Engagqwali engu-316L iyinto ethembekile engagqwali yokusetshenziswa kwemishini yamakhemikhali, yasolwandle, yokucubungula ukudla, yezemithi, yamakhemikhali kaphethiloli kanye neyezimboni. Ukuze bathenge kahle, abathengi kufanele bachaze indinganiso, ibanga, usayizi, ukubekezelelana, ukuqeda ubuso, indlela yokuhlola kanye nezidingo zesitifiketi ngaphambi kokuqinisekiswa kwe-oda.

Ukuze uthole ukuthengwa kobungcweti, ukuhlolwa okubaluleke kakhulu kulula kodwa kubalulekile: qinisekisa ukulingana kwe-UNS S31603 / EN 1.4404, cela i-EN 10204 3.1 MTC, qinisekisa ukulandeleka kwenombolo yokushisa, yenza ukuhlolwa kwe-PMI uma kudingeka, hlola ubukhulu nesimo somphezulu, bese uqinisekisa ukupakishwa kokuthumela ngaphandle ngaphambi kokuthunyelwa.
