Khoom Description
P355NL1 steel phaj yog ib hom zoo zoo zoo nplej steel phaj rau cov hlab ntsha uas tsis muaj qhov kub thiab txias, thiab nws cov yam ntxwv tseem ceeb yog qhov kub thiab txias toughness thiab weldability. Cov phaj hlau no ua tau raws li European tus qauv EN 10028-3, uas yog hom tsis-alloy thiab alloy steel.
P355NL1 steel phaj muaj kev cuam tshuam zoo heev thiab tawg tsis kam ntawm qhov kub thiab txias, yog li nws yog qhov tsim nyog rau kev tsim cov thawv kub thiab cov khoom siv, xws li liquefied gas cia tank, kua nitrogen pipelines, thiab lwm yam. 2}} degrees Celsius thiab tuav lub zog siab thiab kev ntseeg siab.
Tsis tas li ntawd, P355NL1 steel phaj kuj muaj qhov zoo weldability thiab tuaj yeem txuas tau los ntawm cov txheej txheem vuam zoo. Qhov no muab cov chaw tsim khoom nrog cov txheej txheem yooj yim dua thiab yooj yim dua.
P355NL1 steel phaj yog tsuas yog siv rau hauv kev tsim cov hlab ntsha thiab cov kav dej, thiab muaj ntau yam kev siv hauv cov chaw hauv qab no:
1. Kev lag luam roj thiab roj: P355NL1 steel daim hlau tuaj yeem siv los tsim cov tank cia, cov kav dej thiab lwm yam khoom siv siab kub, ua lub luag haujlwm tseem ceeb hauv cov roj thiab roj extraction, khaws cia thiab kev thauj mus los.
2. Kev lag luam tshuaj: P355NL1 steel phaj yog tsim rau kev tsim tshuaj lom neeg cov hlab ntsha, xws li reactors, separators, catalyst carriers, thiab lwm yam., uas tuaj yeem tiv taus qhov kub siab ntawm qhov kub thiab txias.
3. Fais fab kev lag luam: P355NL1 steel phaj tuaj yeem siv los tsim cov hlab ntsha siab thiab cov khoom siv hluav taws xob hluav taws xob hauv lub tshuab hluav taws xob nuclear kom ntseeg tau tias muaj kev nyab xeeb ntawm cov khoom siv hluav taws xob hauv qhov kub thiab txias.
Tus qauv ntawm P355NL1 steel phaj yog tsim raws li European tus qauv EN 10028-3. EN 10028-3 yog cov qauv European rau cov hlau zoo siv hauv cov hlab ntsha siab, suav nrog P275NL1, P275NL2, P355N, P355NH thiab lwm qib ntawm cov hlau.
