Rau kev yuav cov thawj coj thiab engineers koom nrog European lossis thoob ntiaj teb siab - cov haujlwm siab, qhov mob loj tshaj plaws nyob rau hauv kev ua raws li EU PED 2014/68/EU kev cai. Tsis muajPED-cov neeg muab ntawv pov thawj, koj cov cuab yeej siv siab yuav ua tsis tiav kev soj ntsuam kev nyab xeeb, ua rau muaj kev ncua sij hawm tseem ceeb lossis txawm tias tsis raug cai.
Tsis tas li ntawd, cov cua kub exchanger tubes yog ib qho ntawm cov khoom tsis muaj zog tshaj plaws hauv lub thermal system. Kev ua tsis tiav ntawm cov txheej txheem alloy raj feem ntau yog tshwm sim los ntawm:
Local pitting:Ua los ntawm impurities nyob rau hauv cov hlau matrix.
Thermal qaug zog:Cov kab nrib pleb uas tshwm sim thaum lub sij hawm cua sov thiab cua txias.
Siab leakage:Micropores nyob rau hauv lub raj phab ntsa uas yog undetectable los ntawm cov qauv xeem.
NtawmGnee Steel, peb tshem tawm cov kev pheej hmoo no. Raws li ib tugPED-cov chaw tsim tshuaj paus, Gnee SteelmuabGH4169 (sib npaug rau Inconel 718) tubing, tsim los rau xoom xau thiab tsis muaj kev lag luam durability.
