A516Gr70+316L Clad steel phaj Daim ntawv thov
Kev lag luam tshuaj:
Acid Storage Tanks: Tiv thaiv 5–20% sulfuric acid thiab chloride-laden dej khib nyiab.
Reactors: Kuaj cov organic synthesis nyob rau hauv siab thiab kub.
Roj thiab Roj:
Hydrocracking Units: A516Gr70 muab cov qauv kev ntseeg siab, thaum 316L tiv thaiv H₂S thiab chloride corrosion.
Subsea Pipelines: Tiv thaiv dej hiav txwv thiab siab - cov kua hydrocarbon siab.
Marine Engineering:
Desalination Nroj Tsuag: Tiv thaiv cov dej khib nyiab thiab cov tshuaj chlorine-raws li tshuaj tua kab mob.
Shipboard Tanks: Khaws roj lossis dej hiav txwv nrog kev xeb tsawg.
Khoom noj khoom haus thiab Pharmaceuticals:
Cov Khoom Siv Ua Haujlwm: Ua tau raws li FDA cov qauv kev nyiam huv (Ra Tsawg dua lossis sib npaug ntawm 1.6μm) thiab tiv thaiv cov neeg ua haujlwm tu.

Technological Innovations nyob rau hauv cov xwm txheej ua haujlwm tshwj xeeb
Vuam nyob rau hauv qis-Qhov kub thiab txias ib puag ncig
Thaum lub ambient kub<0°C, additional preheating to 200–250°C is required, and the "multi-layer and multi-pass welding" method should be adopted, with the interpass temperature maintained at 150–200°C.
Tom qab- cua sov (250–300 degree, tuav rau 1 teev) yuav tsum tau ua tam sim tom qab vuam kom nrawm hydrogen diffusion.
Kev tiv thaiv tawm tsam Corrosive Media
Transition Layer Upgrade: In environments with Cl⁻ concentration >1000ppm, nws raug nquahu kom siv ER NiCrMo-3 (Inconel 625) rau txheej hloov pauv, uas muaj 9-10% Mo thiab muaj Pitting Resistance Equivalent Number (PREN) Ntau dua lossis sib npaug rau 40.
Txheej Txheej: Tom qab vuam, txheej txheej txheej txheej yog txau nrog epoxy resin / alumina composite txheej (thickness 150-200μm). Lub sij hawm corrosion kuj nyob rau hauv cov tshuaj tsuag ntsev (ASTM B117) tshaj 5000 teev.
Rau cov hlab ntsha siab huv hauv kev lag luam tshuaj / khoom noj khoom haus (xws li, tsis muaj tshuaj tua kab mob, cov khoom siv siv mis), peb muab Q345B+304L Clad steel lossis Q235B+304 Clad steel uas ua tau raws li TSG 21 thiab zaub mov- cov qauv qib. Yog tias koj xav paub txog qhov yuav tsum tau ua ntawm qhov roughness, weldability nrog huv fittings, los yog xam cov nqi ua rau kev kho cov kab noj hniav, xa ib qho kev nug rau kev sib tham thiab cov ntaub ntawv pov thawj.
