2507 Super Duplex

2507 Super Duplex yog lub siab alloy duplex stainless hlau nrog PRE (pitting kuj sib npaug) tus nqi ntawm 42.5 yam tsawg kawg nkaus. Cov qib yog tus cwj pwm los ntawm cov tshuaj chloride corrosion zoo heev, ua ke nrog cov neeg kho tshuab siab heev. Nws yog tshwj xeeb tshaj yog haum rau siv nyob rau hauv ib puag ncig nruj xws li sov chlorinated seawater thiab acidic chloride-muaj xov xwm. Nws yog dav siv nyob rau hauv offshore roj thiab roj kev tshawb nrhiav / ntau lawm thiab nyob rau hauv tshav kub exchangers nyob rau hauv petrochemical / tshuaj ua. Cov qib kuj tseem tsim nyog rau kev siv hydraulic thiab ntsuas kev siv nyob rau hauv qhov chaw sov sov marine.

Hauj lwm lawm

Super Duplex 25 Chrome, los yog 2507, yog txias hardened duplex stainless hlau txhais los ntawm muaj ib tug Pitting Resistance Equivalent Number (PREN) ntau dua 40. Piv rau 22 Chrome / 2205 Duplex, cov alloys muaj ntau dua chromium, molybdenum, thiab nitrogen, uas tsub kom lawv tsis kam mus rau localized pitting thiab crevice corrosion. Nyob rau hauv cov xwm txheej annealed, cov alloys muaj ntau tshaj ob zaug lub zog ntawm cov pa austenitic stainless hlau thiab superior corrosion kuj nyob rau hauv ntau qhov chaw.

APPLICATIONS

Super Duplex 25 Chrome yog siv nyob rau hauv ib puag ncig uas muaj cov tshuaj chlorides lossis cov pa yaj hauv cov pa, xws li cov roj thiab cov qhov dej, cov dej hiav txwv txias, ntsev evaporation, desalination, geothermal qhov dej, cov ntaub so ntswg thiab cov ntawv tsim, thiab kev ua tshuaj lom neeg. Nyob rau hauv cov roj thiab roj, Super 25 Chrome feem ntau yog siv los ua tubing, casing, los yog liners hauv cov dej qaub me me uas muaj cov tshuaj chlorides siab nrog ib nrab siab ntawm H2S Tsawg dua lossis sib npaug li 3 psi. CRA muaj cov khoom tshwj xeeb Super Duplex 25 Chrome seamless yeeb nkab & raj siv rau ntau yam kev lag luam thiab kev siv, suav nrog:

Raws li tubing, casing, thiab liners nyob rau hauv me ntsis qaub roj thiab roj qhov dej uas muaj cov muaj chlorides siab nrog ib nrab siab ntawm H2S Tsawg dua los yog sib npaug rau 3 psi

Cov txheej txheem tshuaj

Super Duplex 2507 yog tsim los rau cov ntawv thov uas yuav tsum muaj lub zog tshwj xeeb thiab kev tiv thaiv corrosion, uas muaj nyob rau hauv cov txheej txheem tshuaj, petrochemical, thiab cov khoom siv dej hiav txwv. Cov hlau yog siv nyob rau hauv ntsev evaporation txheej txheem, tshav kub exchangers, thiab hydrochloric acid ib puag ncig.
