Ubwino Wapamwamba En 10219 S235jrh

Zithunzi Zapamwamba za En 10219 S235jrh Zowonetsedwa

Kufotokozera Kwachidule:

Zogulitsa zathu zimagwirizana ndi miyezo ya ku Europe ndipo zimapangika mozizira, zomwe sizifuna chithandizo chotsatira cha kutentha, kuonetsetsa kuti zili ndi mphamvu komanso kulimba. Kalasi ya S235JRH imadziwika chifukwa cha kuwotcherera kwake komanso mawonekedwe ake, ndikupangitsa kuti ikhale yabwino pamapangidwe omwe kudalirika ndi magwiridwe antchito ndizofunikira.

Mtengo wapamwamba wa nayitrogeni sugwira ntchito ngati mankhwala akuwonetsa kuchuluka kwa Al zomwe zili 0,020 % ndi chiŵerengero chochepa cha Al/N cha 2:1, kapena ngati zinthu zina zokwanira za N-binding zilipo. Zinthu zomangiriza za N zidzalembedwa mu Inspection Document.

Kuyesedwa kwa Hydrostatic

Utali uliwonse wa chitoliro uyenera kuyesedwa ndi wopanga ku mphamvu ya hydrostatic yomwe idzapangitse mukhoma wa chitoliro kupsinjika kosachepera 60% ya mphamvu yokolola yocheperako kutentha. Kupanikizika kumatsimikiziridwa ndi equation yotsatirayi:

Chiyambi cha Zamalonda

Kubweretsa zinthu zathu zapamwamba zamtundu wapamwamba wa EN 10219 S235JRH zozizira zomwe zidapangidwa kuti zikwaniritse zofunikira zama projekiti amakono ndi zomangamanga. Zigawo zathu zopanda pake zimapezeka mumitundu yozungulira, masikweya ndi makona anayi, kuwonetsetsa kusinthasintha komanso kusinthika pamagwiritsidwe osiyanasiyana.

ZathuEN 10219 S235JRHzigawo zopanda pake ndizoyenera kugwiritsa ntchito zosiyanasiyana kuphatikiza zomangamanga, zomangamanga ndi kupanga. Kaya mukuyang'ana zinthu zodalirika za ntchito yomanga yatsopano kapena mukufuna magawo a makina a mafakitale, zinthu zathu zabwino zidzakupatsani mphamvu ndi kukhazikika komwe mukufunikira.

Ubwino wa mankhwala

Chimodzi mwazabwino zazikulu za chitsulo cha S235JRH ndikuwotcherera kwake, ndikupangitsa kuti ikhale yabwino pamapangidwe osiyanasiyana. Zomwe zimakhala zozizira zimalola kuti zikhale ndi miyeso yeniyeni ndi malo osalala omwe angapangitse kukongola kwa kapangidwe kake.

Kuphatikiza apo, zinthuzo zimakhala ndi mphamvu zabwino zamakomedwe komanso ductility, zomwe zimapereka chithandizo chofunikira pamapulogalamu onyamula katundu.

Kuperewera Kwazinthu

Ngakhale S235JRH ndiyoyenera kugwiritsa ntchito masanjidwe ambiri, mwina singachite bwino pakatentha kwambiri kapena pakutentha. Zochita zake zamakina zimatha kukhudzidwa ndi zinthu izi, zomwe zimapangitsa kuti pakhale kukhazikika pakapita nthawi.

Kudalira kuzizira kopanga njira kungathe kuchepetsa makulidwe a magawo omwe amapangidwa, zomwe zingakhale zolepheretsa ntchito zina zolemetsa.

FAQ

Q1. EN 10219 S235JRH ndi chiyani?

EN 10219 chitolirondi muyezo waku Europe womwe umafotokoza za magawo omwe amapangidwa ozizira. Amagwiritsidwa ntchito kwambiri pantchito yomanga chifukwa cha makina ake abwino kwambiri komanso kutsekemera kwake.

Q2. Ubwino wogwiritsa ntchito S235JRH ndi chiyani?

Chitsulo cha S235JRH chili ndi mphamvu zambiri, ductility wabwino komanso weldability wabwino kwambiri, woyenera ntchito zosiyanasiyana zamapangidwe. Makhalidwe ake ozizira-formable amalolanso miyeso yolondola ndi kuchepetsa kulemera.

Q3. Kodi S235JRH ndiyoyenera kugwiritsa ntchito chiyani?

Izi nthawi zambiri zimagwiritsidwa ntchito pomanga nyumba, milatho, ndi zina zomwe zimakhala zolimba komanso zodalirika.

Q4. Kodi ndingatsimikizire bwanji kuti ndimapeza S235JRH yapamwamba kwambiri?

Kugwira ntchito ndi ogulitsa odziwika, monga fakitale yathu ku Cangzhou, kumatsimikizira kuti mukulandira chinthu chomwe chikukwaniritsa zofunikira za EN 10219 standard.
