316L-316Ti-316Hi Ipayipi Lensimbi Engenasici - BLOG

Ukuqonda Okubalulekile

Ithuthukiswe ukumelana nezimo zamakhemikhali ezinolaka, i316 uchungechungeyezinsimbi ezingagqwali-okuhlanganisa316L, 316H, kanye no-316Ti-inikeza ukumelana okukhethekile nokugqwala kwe-chloride ne-oxidation.

Ibanga ngalinye linikezela ngezidingo ezihlukile zokushisa noma zokwenziwa, lihlinzeka ngokuvumelana nezimo konjiniyela kuzo zonke izimboni ezicutshungulwayo, amasistimu kagesi, kanye nezindawo zasolwandle.

316L:Okuhlukile{0}kwekhabhoni ephansi okunciphisa imvula ye-carbide ngesikhathi sokushisela.
316H:Ibanga{{0}eliphezulu lekhabhoni elilungiselelwe{1}}lamandla aphezulu ezinga lokushisa kanye nokungazwani nokunyakaza.
316Ti:I-Titanium{0}}inguqulo ezinzile ethuthukisa ukugqwala kwe-intergranular kumazinga okushisa esevisi aphakeme.

I-alloy Design kanye ne-Corrosion Behavior

I-alloy's18% chromium kanye 12% nickelisisekelo sakha isakhiwo esizinzile se-austenitic, ngenkathii-molybdenum (~2.0–3.0%)kukhulisa kakhulu ukumelana nokubola kwe-pitting kanye nokuqhekeka ku-chloride-ephethe imidiya.

Ukulungiswa kwe-Titanium noma kwekhabhoni elawulwayo kuvumela ukusebenza okuvumelanayo-kungaba kumapayipi e-cryogenic noma kuma-superheater assemblies.

Izinzuzo ezibalulekile ze-metallurgical:

Ukumelana okuhle kakhulu kwe-acetic, i-phosphoric, ne-sulfuric acid
Ukungavikeleki okuphezulu ku-chloride{0}kubangele ukuqhekeka kwe-corrosion kwengcindezi
Ukwakheka kwefilimu ye-oxide ezinzile kufika ku-870℃(1600℃F)
Ubuqotho be-weld obuvelele obunobungozi obuncane bokuzwela

Okuphawulwa ngomshini:

I-316L ilungele kakhulu imihlangano ehlanganisiwe namapayipi we-cryogenic; I-316H ne-316Ti zihamba phambili ezimeni eziqhubekayo{3}}zezinga lokushisa eliphezulu nokusebenza okuthuthukisiwe kokuchwensa.

Umzila Wokukhiqiza Nokwenza

Ukwenziwa kwamapayipi ensimbi engagqwali angu-316 kudinga ukulawulwa kwensimbi okunembile ukuze kulondolozwe ukumelana nokugqwala kanye nokufana kwemishini.

Ngokungafani nezinsimbi zekhabhoni, lezi zingxubevange ze-austenitic zidinga izindawo ezincibilikayo ezihlanzekile, ukulawulwa okuqinile kwezinga lokushisa, namazinga okupholisa alawulwayo ukuze kuvinjelwe ukuzwela noma ukuhwamuka kokusanhlamvu.

Ukugeleza kokukhiqiza okujwayelekile:

Ukuncibilika kweVacuum noma i-Argon Furnace:Icolisa i-alloy chemistry futhi inciphise ukungcoliswa kwe-nitrogen noma sulphur.
Ukubhoboza Okushisayo Nokwelula:Iguqula amabhilidi aqinile abe yizimbobo ezingenamthungo ezinokugeleza okusanhlamvu okuqondile okubekezelela ingcindezi ephezulu.
Umdwebo Obandayo kanye Nosayizi:Ifinyelela ukubekezelelana okunembile, ukugxila okuthuthukisiwe, nokushelela okuthuthukisiwe kwendawo.
Ukufaka Isixazululo:Kwenziwa phakathi kwe-1040℃kanye ne-1120 degree, kulandelwa amanzi asheshayo noma ukucisha umoya ukuze kuncibilike ama-carbides nokubuyisela ukumelana nokugqwala okugcwele kwe-austenitic.
Pickling and Passivation:Isusa ama-oxide futhi ibuyisela ifilimu ecebile ye-chromium-ebalulekile ukuze iqine ezindaweni ezine-acidic noma i-chloride{1}}ecebile.

Amapayipi ashiselwe akhiwe kusetshenziswaI-GTAW (TIG)nomalaser weldingngezinto zokugcwalisa ezifaniswe nokwakheka kwesisekelo (ER316L noma ER316Ti).

I-post-i-weld solution annealing and polishing ingase isetshenziswe ukuze kubuyiselwe ukumelana nokugqwala ekufakweni kwenqubo ebalulekile njengamasistimu amapayipi amakhemikhali nawekhemisi.

Ukuhlola Nokuqinisekisa Ikhwalithi

Ukuhlola okuphelele kuqinisekisa ukuthi wonke amapayipi ensimbi engagqwali angu-316{1}}agcina ukuqina kwe-metallurgical nokusebenza okungavuzi ngaphambi kokulethwa.

Izinqubo zokuhlola zihambisana neI-ASTM A312, A999, nokuhambisanayoI-ASME SAukucaciswa, okuhlanganisa kokubili izigaba zokuqinisekisa{0}ezingonakali futhi ezingonakali.

Ukuhlolwa kwekhwalithi ejwayelekile:

I-Hydrostatic noma i-Eddy-Ukuhlola Kwamanje:Iqinisekisa ubuqotho bangaphakathi futhi ithola ukungaqhubeki kwendawo.
Ukuhlolwa Kokuqina, Ukuqina, kanye Nokuqina:Qinisekisa ukuvumelana kwemishini kuzo zonke izindawo zokukhiqiza.
I-Intergranular Corrosion Test (ASTM A262 Practice E):Iqinisekisa ukungatheleleki emvuleni ye-carbide, ikakhulukazi ku-316L naku-316Ti.
I-Positive Material Identification (PMI):Iqinisekisa ukuthobelana kwe-alloy nokuqukethwe kwe-Cr-Ni{1}}Mo.
Ukuhlola Okubonakalayo Nobukhulu:Ikala ubuqotho, isiphetho, nokufana kodonga ngamageji anembayo.

Okokuhlanzeka okuphezulu{{0}noma inqubo{1}}yezinhlelo zokusebenza ezibalulekile, ngokuzithandelaukuhlaziywa kwe-ferrite, ukuhlolwa kwe-radiographic weld, nomaukuhlolwa kokuqina kobuso (i-Ra Ngaphansi noma ilingana no-0.8 μm)ingashiwo.

Yonke idatha yokuhlola irekhodwa ngaphansi kwemibhalo ye-QA elawulwayo futhi ikhishwe njengeZU 10204 3.1 / 3.2 izitifiketiukuze kulandeleke ngokuphelele.

Ukusebenza Kusevisi

I-316L, 316H, kanye ne-316Ti ngayinye ibonisa ukuqina okuyingqayizivele ngaphansi kwengcindezi yokusebenza:

316L:Yinhle kakhulu ekushiseleni{0}}izinto ezisindayo, ezinciphisa imvula ye-carbide.
316H:Imelana nokukhasa kanye nokugqabuka ngaphansi kokuchayeka ku-thermal isikhathi eside.
316Ti:Igcina i-ductility nokuvikela ukugqwala ngisho nangemva kwemijikelezo eminingi yokushisisa.

Isendlalelo sazo se-oxide esizinzile kanye nokungeneka okuphansi kubenza bafaneleke kokubiliukudla-ibangafuthiamakhemikhali inqubo izinhlelo.
