Umuyoboro w'icyuma gifunganye ufite 316L | Inkingi y'icyuma cya karuboni n'icyuma gifunganye kuri serivisi ya CO₂, boiler, ihindura ubushyuhe n'ubushyuhe buri hasi - Womic Steel

Q1: Ni ubushyuhe buke cyane bwa litiro 316 mu gupfuka mu buryo bwa elegitoroniki?
A: 316L ishobora gukoreshwa kugeza kuri450°C(840°F) mu buryo buhoraho bwo kwangiza. Hejuru y'ibyo, hashobora kubaho uburyo bwo kugabanya ubukana bw'imyobo. Ku bushyuhe bwinshi, tekereza ku gupfuka Alloy 825 cyangwa 625.

Q2: Ese umuyoboro wa 316L upfundikiye ushobora gukoreshwa mu gutanga serivisi ishyushye (H₂S)?
A: 316L niimipakamuri serivisi y'umusemburo. NACE MR0175 / ISO 15156 yemerera 316L mu duce duto gusa iyo: chloride iri hasi (<50 ppm), pH >3.5, ubushyuhe <60°C, na H₂S igice cy'umuvuduko <0.05 psi. Ku mwuka usanzwe w'umusemburo utose (H₂S nyinshi), turagusaba gukoresha Incoloy 825 cyangwa Alloy 28 cladding.

Q3: Ni ikihe cyuma gishyigikira nkwiye guhitamo mu rukuta rw'amazi rwa boiler?
A:SA-210 Gr.Cni cyo gipimo ngenderwaho ku nkuta z'amazi n'ibikoresho bitanga ubukungu. Niba boiler yawe ari nto cyane kandi ubushyuhe bw'icyuma buri munsi ya 450°C, iyi ni yo mahitamo ahendutse cyane.

Q4: Nkeneye imbaraga zo gukomera ku bushyuhe buke (-45°C). Ese nshobora gukoresha cladding ya 316L?
A: Yego. Hitamo icyuma gishyigikiraASTM A333 Gr.6Igeragezwa ry’ingaruka kuri -45°C. Ipfundo rya 316L ntirigira ingaruka ku miterere y’ingaruka; riguma ritoroshye ku bushyuhe buri hasi. Umuyoboro wose upfundikiwe ushobora gutangwa n’isuzuma ryuzuye rya Charpy.

Q5: Ku muyoboro wa CO₂ ufite umuvuduko mwinshi (1500 psi, 80°C), ni ubuhe buryo usaba kuvanga?
A:Inkingi ya API 5L X65(ku bw'imbaraga) +Igipfundikizo cya 316L 2.5-3.0 mm(ku bijyanye no kwangirika kw'ibinure). Iki ni igisubizo gisanzwe cya gaze isukura gikoreshwa cyane mu Burasirazuba bwo Hagati na Amerika ya Ruguru.

Q6: Ni irihe tandukaniro riri hagati ya SA-106 Gr.B na SA-210 Gr.C ku muyoboro upfutse?
A: SA-210 Gr.C ifite imbaraga zo gukurura cyane (485 MPa vs 415 MPa) kandi igenewe by'umwihariko imiyoboro ya boiler. SA-106 Gr.B igenewe imiyoboro ikoresha ubushyuhe bwinshi muri rusange. Ku miyoboro ikoreshwa, koresha SA-210; ku miyoboro yo koherezamo ibikoresho, SA 106 iremewe.

Q7: Ese nshobora kubona icyemezo cya EN 10204 Type 3.2 kuri iyi miyoboro ipfundikiye?
A: Yego. Dukorana na TÜV, BV, DNV, SGS, na ABS. Hari indishyi y'inyongera kandi igihe cyo kuyikoresha kigera ku cyumweru kimwe cyangwa bibiri.

Q8: Ese isano iri hagati ya 316L n'icyuma cya karuboni ishobora kwangirika na hydrogen?
A: Muri serivisi ya CO₂ nziza (nta volteji nyinshi irinda cathodic), oya. Muri serivisi ya sour (H₂S), uburyo bwo guhuza ibyuma ntabwo ari inzira nziza yo gucikamo ibice iyo ikozwe neza. Ariko, 316L ubwayo ifite imipaka yo gukomera. Kuri H₂S nyinshi, turagusaba gukoresha nickel alloy clad.

Q9: Ubugari bwa cladding bwa litiro 316 ni ubuhe wasaba?
A: 1.5 mm ni yo ntarengwa yo kugira ngo habeho ubufatanye bwizewe n'uburyo bwo kwangirika. Ku bijyanye na serivisi ya CO₂ ikomeye kandi ifite umuvuduko mwinshi w'amazi, turagusaba 2.5-3.0 mm.

Q10: Ese ushobora gutanga iyi miyoboro ipfundikiye mu buryo bwa U-bent ku byuma bihindura ubushyuhe?
A: Yego, ku muyoboro udafite umugozi (OD ≤168 mm). Dukoresha mandrel mu gukonja, hanyuma tugakoresha ubushyuhe bugabanya stress, hanyuma tugakoresha NDT 100% y'ubuso bugonda. Saba ikiguzi gitandukanye cya U-gonda.

Q11: Ese mutanga "igikoresho cyo guhitamo imiyoboro ipfundikiye" ku byuma bitandukanye biyikikije?
A: Yego. Tubwire ibisabwa kuri serivisi yawe: ubushyuhe ntarengwa, ubushyuhe buke, umuvuduko, imiterere y'amazi (CO₂, H₂S, chloride, pH). Tuzagusaba gukoresha icyuma gishyigikira + ubugari bwa cladding + urwego rwo kugenzura.

Q12: Ese hari itandukaniro rinini ku giciro kiri hagati ya SA-210+316L n'umuyoboro ukomeye wa 316L?
A: Yego. Ku muyoboro w'urukuta wa 63.5mm OD × 5mm, 316L ikomeye ni hafibihenze inshuro 2.5-3kurusha umuyoboro wa SA-210+316L upfundikiye (upfundikiye 2mm). Uko urukuta rurushaho kuba runini, niko ubwizigame burushaho kuba bunini.

Q13: Kuki nahitamo umuyoboro udafite umugozi kuruta umuyoboro upfutse?
A: Umuyoboro udafite umushono ukurahoumushonge uwo ari wo wose wo gusudira mu gihe kirekire, ibyo bikaba ari byiza mu bijyanye no gukora akazi gakomeye mu bushyuhe bwinshi, gukora akazi ka hydrogen, no mu gihe hari ibyago byo kuba chloride SCC yakwibasira imashini isuka. Ku miyoboro myinshi ikoreshwa mu buryo bwa "line" (X65+316L), imiyoboro isuka mu buryo bwa "welded" yizewe cyane kandi ihendutse.

Q14: Ese ushobora kwambara indangamuntu na OD byombi?
A: Turabishoboye, ariko ibyo ni umwihariko. Ubusanzwe urwego rumwe rwa CRA kuri ID rurahagije. Ku bijyanye no kwangirika kw'inyuma, turagusaba irangi, gusiga irangi, cyangwa uburyo butandukanye bwo gupfuka inyuma (urugero, gupfuka hejuru). Nyamuneka ubaze niba hari ipfuka ebyiri.

Q15: Nigute natumiza uruvange rw'ibyuma bivangiye inyuma?
A: Tanga umurongo kuri buri kimwe: urwego rw'icyuma gishyigikiwe, OD, ubwinshi bw'inkingi, ubugari bw'igipfundikizo, uburebure, ingano. Tuzatanga ibiciro kuri buri kimwe. Igerageza ryoroheje ry'ingano imwe riraremewe.

Q16: Ese gusya ibinyampeke ni ngombwa kugira ngo upfuke 316L?
A: Yego. Gutunganya bikuraho ubushyuhe bwakozwe mu gihe cyo gusohora no gutunganya ubushyuhe, bigasubizaho urwego rudakora, kandi bigatuma ubuso busukuye kugira ngo bugenzurwe. Uburyo dukoresha burimo gusya kandi bugashyirwa mu buryo busanzwe. Niba udashaka gusya (urugero, kugira ngo uhite upfukwa), nyamuneka vuga.

Q17: Ese mutanga PMI (Positive Material Identification) kuri cladding ya 316L?
A: Yego. Dushobora gukora XRF ahantu henshi kuri buri muyoboro, kandi tugashyira raporo muri dosiye y'ubuziranenge. Hari amafaranga make kuri buri muyoboro ku bicuruzwa binini.

Q18: Ese umuyoboro upfundikiye ushobora gushyirwamo impera zipfundikiye hamwe n'amavuta ya CRA?
A: Yego. Inguni isanzwe ya bevel 30-35° hamwe na mm 1.6. Gutera amavuta ya CRA (mm 2-3 za Alloy 625 cyangwa 316L filler ku ruhande rwa bevel) birahari kugira ngo hirindwe ko amazi yagabanuka mu gihe cyo gusudira. Ibi ni byiza cyane cyane ku gusudira mu gihe cy'umuvuduko mwinshi.

Q19: Ni ubuhe bunararibonye bwawe mu gutanga imiyoboro ya 316L ipfundikiye ikurikije amahame ya EN y'i Burayi?
A: Dutanga buri gihe EN 10216-2 (inyuma) hamwe n'igitambaro cya 1.4404 (316L). Dushobora gutanga ibyemezo bya EN 10204 3.2 hamwe n'ubuhamya bwa TÜV n'itangazo rya PED. Amabwiriza menshi yagiye mu Budage, mu Buholandi, mu Bufaransa no mu Bwongereza.

Q20: Ese ushobora gusangira ingero z'umuyoboro munini wa 316L upfutse (API 5L X65+316L)?
A: Yego, twatanze umuyoboro wa X65+316L upfundikiye (OD 610mm, upfundikiye 2.5mm) ku mushinga wo gutera CO₂ mu Burasirazuba bwo Hagati (umuyoboro wa kilometero 200). Imbonerahamwe iboneka kuri NDA.
