Duplex idafite ibyuma idafite microstructure yibice bibiri, aho ingano yubunini bwa ferrite na austenite igera kuri 50%. Bitewe na microstructure yibice bibiri, ibyuma bihuza ibyiza byiza bya ferritic na austenitis ibyuma bitagira umuyonga. Muri rusange, icyiciro cya ferritic (cyibanze ku mubiri wa cubic lattice) gitanga imbaraga zubukanishi, ubukana bwiza hamwe no kurwanya ruswa, mugihe icyiciro cya austenitis (face-centre cubic lattice) gitanga ihindagurika ryiza.
Bitewe no guhuza iyi mitungo, ibyuma bya duplex bidafite ingese bikoreshwa cyane mubikorwa bya peteroli, impapuro, impapuro, inganda ningufu. Barashobora kwihanganira ibidukikije bikaze, kwagura ubuzima bwa serivisi no gukora mubihe bidukikije bikabije.
Ibikoresho bikomeye-bigabanya ubunini nuburemere bwigice. Kurugero, super duplex ibyuma bitagira umuyonga birashobora gutanga inshuro eshatu kugeza enye imbaraga zumusaruro hamwe no guhangana na 316 ibyuma bitagira umwanda.
Duplex ibyuma bidafite ibyuma bishyirwa mubyiciro bitatu bishingiye kuri gravimetric chromium (Cr) hamwe na piting resistance ihwanye numubare uhwanye (PREN):
Kimwe mu bintu by'ingenzi byo gusudira DSS, SDSS, HDSS hamwe n'ibyuma bidasanzwe bivanga ibyuma ni kugenzura ibipimo byo gusudira.
Ibisabwa kugirango gahunda yo gusudira mu nganda za peteroli itegeka byibuze PREN isabwa ku byuma byuzuza. Kurugero, DSS isaba PREN agaciro ka 35, mugihe SDSS isaba PREN agaciro ka 40. 1 yerekana DSS nicyuma cyuzuza cya GMAW na GTAW. Nibisanzwe, Cr ibirimo mubyuma byuzuza bihuye nibiri muri Cr mubyuma fatizo. Uburyo bumwe bwo gusuzuma mugihe ukoresheje GTAW kumizi numuyoboro ushyushye nugukoresha superalloy yuzuza ibyuma. Niba icyuma gisudira kidafite ubumuga kubera tekiniki mbi, icyuma cyuzuza cyane icyuma gishobora gutanga PREN yifuzwa hamwe nizindi ndangagaciro zicyitegererezo.
Nkurugero, kugirango ubigaragaze, ababikora bamwe basaba gukoresha SDSS (25% Cr) yuzuza insinga zuzuza DSS (22% Cr) zivanze na HDSS (27% Cr) insinga zuzuza SDSS (25% Cr). HDSS yuzuza insinga irashobora kandi gukoreshwa kuri HDSS. Iyi duplex ya austenitis-ferritic irimo ferrite igera kuri 65%, chromium 27%, nikel 6.5%, nikel 5% ya molybdenum kandi ifatwa nkibiri munsi ya 0,015% ya karubone.
Ugereranije na SDSS, gupakira HDSS bifite imbaraga nyinshi zo gutanga umusaruro no kurwanya neza imyanda no kwangirika. Ifite kandi imbaraga zo guhangana na hydrogène yamenetse kandi irwanya cyane aside iruta SDSS. Imbaraga zayo nyinshi bisobanura amafaranga make yo gufata neza mu gutunganya imiyoboro, kubera ko icyuma gisudira cyingufu zihagije kidasaba isesengura ryibintu bitagira ingano kandi ibipimo byo kwemererwa birashobora kuba bike.
Urebye ibintu byinshi byibanze, ibisabwa byubukanishi nuburyo bukoreshwa, nyamuneka ubaze DSS hamwe ninzobere zuzuza ibyuma mbere yo gukomeza umushinga wawe utaha.
WELDER, yahoze yitwa Practical Welding Uyu munsi, ihagarariye abantu nyabo bakora ibicuruzwa dukoresha kandi dukorana burimunsi. Iki kinyamakuru kimaze imyaka isaga 20 gikorera umuryango wo gusudira muri Amerika ya Ruguru.
Noneho hamwe nubushobozi bwuzuye kuri FABRICATOR integuro ya digitale, byoroshye kubona umutungo winganda zingirakamaro.
Igitabo cya Digitale y'Ikinyamakuru Tube & Pipe ubu kiragerwaho rwose, gitanga uburyo bworoshye bwo kubona ibikoresho by'inganda bifite agaciro.
Shakisha uburyo bwuzuye bwa digitale kubinyamakuru STAMPING, byerekana ikoranabuhanga rigezweho, imikorere myiza namakuru yinganda kumasoko ya kashe.
Noneho hamwe na digitale yuzuye kuri Fabricator en Español, ufite uburyo bworoshye bwo kubona ibikoresho byinganda bifite agaciro.
