ASTM A213 TP316L U-Tube Bundle rau Gas Chiller

Raws li tus neeg xa khoom thoob ntiaj teb ntseeg siab, GNEE muaj cov kev paub dhau los hauv kev muab ASTM A213 TP316L U-tube pob rau cov roj txias. Peb cov khoom tau raug xa mus rau ntau tshaj 50 lub teb chaws thoob ntiaj teb, nrog rau txhua xyoo export ntim ntau tshaj 1,000 tons. Tag nrho cov ntaub ntawv raw yog tsim los ntawm cov hlau mills tsim nyog thiab tau txais 100% PMI (Positive Material Identification) pov thawj; peb muab cov ntawv ceeb toom thawj zeb xeem (MTRs) sib raug rau cov lej tshwj xeeb rau cov cua sov, ua raws li EN 10204 3.1 lossis 3.2 tus qauv.

 

TP316L stainless hlau U- raj muaj cov tshuaj muaj pes tsawg leeg uas muaj tsawg dua lossis sib npaug ntawm 0.03% Carbon thiab 2.0–2.5% Molybdenum, kom ntseeg tau qhov tshwj xeeb tiv thaiv chloride corrosion thiab ntev - lub sijhawm ruaj khov. Thaum lub sij hawm U-bending txheej txheem, peb nruj me ntsis tswj cov phab ntsa thinning kom tsawg dua los yog sib npaug li 10% thiab ovality kom tsawg dua los yog sib npaug li 8%, yog li lav tias lub raj bundles tswj lawv cov qauv kev ncaj ncees thiab xyuas kom meej haum thaum lub installation. Ua raws li cov txheej txheem khoov, tag nrho U- raj tau txais kev kho cov tshuaj annealing (ntawm ntau dua lossis sib npaug li 1040℃tom qab quenching ceev) txhawm rau txo qis kev ntxhov siab, rov ua kom muaj zog corrosion, thiab xyuas kom meej tias tsis muaj micro- tawg tau tsim thaum khoov.

Hais txog qhov zoo ntawm kev sib txuas ntawm cov hlua khi thiab cov ntaub ntawv raj, peb siv cov raj xaim thiab vuam cov txheej txheem los xyuas kom meej cov ntsaws ruaj ruaj ntawm cov pob qij txha, yog li txo qhov kev pheej hmoo ntawm kev xau raws li qhov hloov pauv siab thiab qhov kub thiab txias. Kev tsim kev kam rau peb TP316L U- cov khoom siv raj nruj nruj ua raws li TEMA Class R cov qauv, kom ntseeg tau tias muaj siab precision hauv raj ntev, kev sib luag, thiab tag nrho cov pob geometry. Qhov no guarantees tus txheej txheem sib dhos du thaum txo qis kev teeb tsa cov sij hawm ua haujlwm.
