Cov qhab nia xaiv tau
- Piv rau TP304 thiab TP316, TP347 yog qhov zoo dua rau kev ua haujlwm ntev -lub sij hawm siab- kub thiab siv nyob rau hauv refinery heaters, converters, thiab siab - kub petrochemical pipelines.
- 904L yog lub siab- alloy austenitic stainless hlau uas muaj kev tiv thaiv zoo rau pitting thiab crevice corrosion piv rau TP316; nws yog ua hauj lwm nyob rau hauv acid nroj tsuag, chiv ntau lawm units, thiab seawater txias tshuab.
- Alloy 600 khaws nws lub zog thiab corrosion kuj thaum lub sij hawm luv luv -lub sij hawm raug kub tshaj 1000℃; nws yog siv nyob rau hauv cov tshuaj reactors, lub cub tawg Cheebtsam, thiab siab -petrochemical khoom kub.
thaj chaw thov
- Hauv cov roj refineries: siv rau kev thauj cov roj crude, thauj cov khoom ua kom zoo, hydrocracking systems, catalytic cracking systems, boiler superheaters/reheaters, thiab high -kub pipelines;
- Nyob rau hauv cov nroj tsuag petrochemical: siv rau cov tshuaj feedstock pipelines, pipelines rau conveying acidic thiab alkaline media, txuas pipelines rau tshuaj reactors, hnyav thauj pipelines, thiab condensate rov qab pipelines;
- Nyob rau hauv offshore roj engineering: siv rau seawater txias pipelines ntawm offshore platforms, nkoj ballast dej systems, thiab offshore roj thiab roj xa mus pipelines.

FAQ
Q: Dab tsi yog qhov txawv ntawm ASTM A358 thiab ASTM A312?
A: Thawj qhov sib txawv yog nyob rau hauv cov txheej txheem tsim khoom. ASTM A358 npog hluav taws xob- fusion-welded (EFW) yeeb nkab, hos ASTM A312 npog ob leeg seamless yeeb nkab thiab hluav taws xob-kuj-welded (ERW) yeeb nkab (tsim yam tsis muaj qhov sib ntxiv ntawm cov hlau nplaum). ASTM A358 tso cai rau kev tsim cov diameters loj dua thiab nta cov phab ntsa tuab tuab dua.
Q: Koj ua li cas kom ntseeg tau tias cov khoom welds yog tag nrho fused thiab tsis muaj kev pheej hmoo ntawm to?
A: Peb siv dual -them hluav taws xob Fusion Vuam (EFW) txheej txheem los xyuas kom meej tias qhov sib nqus nkag qhov tob yog sib npaug los yog ntau dua 100% ntawm cov yeeb nkab phab ntsa thickness. Tsis tas li ntawd, txhua lub yeeb nkab tau dhau 100% kev kuaj hluav taws xob (RT) rau kev kuaj pom qhov tsis zoo, ua raws li kev tshaj tawm -weld solution annealing treatment.
Q: Cov kev xaiv saum npoo av dab tsi muaj?
A: Cov khoom lag luam feem ntau yog muab rau hauv qhov kaj annealed mob; Txawm li cas los xij, peb kuj tseem muaj ntau yam kev kho deg ntxiv, suav nrog pickling thiab passivation, mechanical polishing (xws li 180-grit mus rau 600-grit daim iav tiav), electropolishing, thiab sandblasting.
