Lub thermal conductivity ntawm duplex stainless hlau (~ 15 W / m·K) yog siab dua li ntawm austenitic stainless hlau, thaum nws coefficient ntawm thermal expansion (~ 13 × 10⁻⁶ / degree) yog ze rau cov carbon hlau. Rau lub plhaub - thiab - raj kub exchangers, tus yam ntxwv no yuav pab kom txo tau thermal stress ntawm lub tubesheet thiab lub raj pob.
U khoov tubing qhia tau zoo heev tiv thaiv seawater corrosion; Tshwj xeeb, Qib 1.4462 muaj Pitting Resistance Equivalent Number (PREN) ntawm ntau dua lossis sib npaug rau 35, thiab Qib 1.4410 muaj PREN ntau dua lossis sib npaug rau 42, ua rau lawv tiv taus siab -chloride seawater ib puag ncig- muaj 35 chloride ntawm 35,000 ppm. ions{10}} dhau lub sijhawm ncua.

Cov qhab nia xaiv tau
- Rau kev khiav hauj lwm uas muaj ambient - kub, qis - salinity seawater, 1.4404 (316L) austenitic stainless hlau yog ib qho kev xaiv tsim nyog; nws zoo - haum rau me me - nplai, qis- parameter seawater desalination units thiab muab cov nqi qis dua.
- Rau cov dej hiav txwv evaporation uas muaj qhov kub siab tshaj 70℃thiab cov tshuaj chloride ion ntau dua 60,000 ppm, 904L super- austenitic stainless hlau yuav raug xaiv; Txawm li cas los xij, vim nws lub zog qis dua li ntawm duplex stainless hlau, nws yuav tsum siv cov phab ntsa tuab tuab.

FAQ
Q: Dab tsi yog qhov tsawg kawg nkaus khoov vojvoog muaj rau cov khoom siv U- khoov?
A: Tus qauv dabtsi yog khoov vojvoog yog 1.5 npaug ntawm cov yeeb nkab sab nraud (R=1.5D). Peb tseem tuaj yeem muab kev kho kom haum khoov khoov mus rau R=1.2D, raws li kev soj ntsuam ntawm cov phab ntsa tshwj xeeb thiab cov txheej txheem sab nraud.
Q: Puas yog cov tshuaj annealing yuav tsum tau tom qab txoj kev khoov?
A: Yog. Cov txheej txheem khoov txias qhia txog deformation martensite thiab kev ntxhov siab sab hauv, uas cuam tshuam rau kev tiv thaiv corrosion. Peb cov txheej txheem tsim cov txheej txheem suav nrog kev tshaj tawm - khoov kho annealing nyob rau hauv ib puag ncig tiv thaiv, tam sim ntawd tom qab pickling.
Q: Dab tsi yog qhov zoo ntawm kev siv duplex stainless hlau U- khoov piv rau titanium U- raj?
A: Thaum titanium muaj qhov tshwj xeeb corrosion kuj, nws raug kev txom nyem los ntawm thermal conductivity, tus nqi siab, thiab yuav tsum tau tshwj xeeb cov txheej txheem rau raj - mus rau -tubesheet expansion koom. Duplex stainless hlau (piv txwv li, 1.4410), conversely, muaj lub zog txhua yam muaj zog -ua kom qhov hnyav txo - thiab nta ib coefficient ntawm thermal expansion uas zoo sib xws ntawm cov tubesheet, kom ruaj khov thiab txhim khu kev qha expansion pob qij txha; Ntxiv mus, nws muab tus nqi qis dua.
