Mu gawo la mafakitale otukuka komanso olamulidwa bwino ku Europe, magwiridwe antchito, kudalirika, ndi kutsatira malamulo a zinthu ndizofunikira kwambiri. Pakati pa zinthu zambiri zofunika kwambiri, chubu chachitsulo chosasunthika cha EN 10216 S355J2H, chodziwika bwino chifukwa cha makhalidwe ake abwino kwambiri, chakhala chisankho chokondedwa m'mafakitale angapo akuluakulu, kuyambira zomangamanga zamagetsi mpaka kupanga makina olemera. Nkhaniyi ikufotokoza za mawonekedwe a chitsulo ichi, miyezo yomwe chimatsatira, ndi momwe chimagwiritsidwira ntchito kwambiri pamsika waku Europe.

Kumvetsetsa Muyezo ndi Zinthu Zofunika: EN 10216 ndi S355J2H

Choyamba, ndikofunikira kumvetsa tanthauzo la dzina lake:

•EN 10216: Iyi ndi mndandanda wa miyezo ya ku Europe yomwe imafotokoza momveka bwino momwe machubu achitsulo chosasunthika amagwirira ntchito kuti azitha kupanikizika. Muyezo uwu umatsimikizira kuti machubuwo amasunga mawonekedwe awo amakina kutentha kwambiri, zomwe zimapangitsa kuti akhale oyenera kugwiritsa ntchito zida zopanikizika. Mabaibulo aposachedwa asinthidwa ndi zigawo monga EN 10216-1 ndi EN 10216-2, koma mtundu wa S355J2H ndi zofunikira zake zapititsidwa patsogolo.

•S355J2H:

◦S: Amayimira "Chitsulo Chomangira".

◦355: Imasonyeza mphamvu yocheperako ya 355 Megapascals kutentha kwa chipinda, kutanthauza kuti imapereka kukana bwino ku kusintha kwa kutentha ndi mphamvu yonyamula katundu.

◦J2: Imayimira kalasi ya Impact Toughness. Izi zikutanthauza kuti mayeso a Charpy V-notch impact amachitika pa -20°C ndipo imakwaniritsa zofunikira zinazake zoyamwa mphamvu. Izi zimaonetsetsa kuti zinthuzo zimasunga kulimba kwabwino ku kusweka kwa fracture ngakhale m'malo ozizira, zomwe ndizofunikira kwambiri pakupanga zinthu zakunja m'madera monga Northern Europe.

◦H: Amayimira "Normalized Condition". Izi zikutanthauza kuti chubu chachitsulo chakhala chikusinthidwa kutentha kuti chiwongolere kapangidwe ka tirigu, kukonza kapangidwe kake, ndikuwonjezera mphamvu zake zamakanika ndi kulimba, zomwe zimapangitsa kuti zikhale zofanana komanso zokhazikika.

Mwachidule, EN 10216 S355J2H ndi chubu chachitsulo chosasunthika chomwe chili ndi mphamvu zambiri, kulimba kwabwino kwambiri kutentha kochepa, komanso kudalirika, komwe kwapangidwira makamaka malo opanikizika komanso opsinjika kwambiri.

Madera Ofunikira Kwambiri ku Msika wa ku Ulaya

Kapangidwe ka machubu osasunthika a S355J2H kamapangitsa kuti akhale oyenera kwambiri pakufunika kwakukulu kwa chitetezo, magwiridwe antchito, komanso kukhazikika m'makampani aku Europe. Magawo omwe amagwiritsidwa ntchito kwambiri ndi awa:

1. Gawo la Mphamvu ndi Mphamvu

•Mafuta ndi Gasi: Amagwiritsidwa ntchito pokonza mapaipi, mipiringidzo yosonkhanitsira, zotengera zopanikizika, ndi machubu a boiler pamapulatifomu a m'mphepete mwa nyanja ndi m'mphepete mwa nyanja. Kukana kwake kupanikizika ndi magwiridwe antchito otsika kutentha ndizofunikira kwambiri pothana ndi ma hydrocarbon oyaka moto komanso ophulika.

•Mphamvu Yotenthetsera ndi Kutentha kwa Chigawo: Imagwiritsidwa ntchito kwambiri mu ma superheater, ma reheater, ndi machubu osungira zinthu zamagetsi a malo opangira magetsi, komanso mizere yayikulu yamakina otenthetsera m'mizinda. Imatha kupirira zotsatira za nthawi yayitali za nthunzi yotentha kwambiri komanso yothamanga kwambiri.

•Mphamvu Zobwezerezedwanso: Mapaipi oterewa amafunikanso m'mafakitale opanga mphamvu za biomass ndi mapulojekiti ena a geothermal.

2. Ntchito Yomanga ndi Zomangamanga

•Ntchito Zolimba Zomanga: Zimagwiritsidwa ntchito popangira zipilala zothandizira ndi nyumba zonyamula katundu m'nyumba zazikulu monga mabwalo amasewera, ma eyapoti, milatho, ndi mafakitale. Mphamvu zake zambiri zimathandiza kupanga nyumba zopepuka komanso zolimba.

•Makina Omanga: Amagwira ntchito ngati migolo ya silinda ya hydraulic ndi zida zomangira zida zolemera monga ma excavator ndi ma crane, zomwe ziyenera kupirira kupsinjika kwakukulu komanso kugwedezeka.

3. Makampani a Mankhwala ndi Njira

•Amagwiritsidwa ntchito popanga ma reactor, ma heat exchanger, ma column, ndi ma processing payipi system komwe zipangizo nthawi zambiri zimagwira ntchito zowononga kapena zoopsa pansi pa kutentha kwakukulu ndi kupanikizika. Kudalirika ndi kusinthasintha kwa S355J2H ndikofunikira kwambiri pakuonetsetsa kuti ntchitoyo ikuyenda bwino.

4. Ntchito Zina Zamakampani

•Amagwiritsidwa ntchito popanga masilinda a gasi a mpweya wopanikizika (monga mpweya wa mafakitale, mpweya wamankhwala) motsatira malamulo okhwima a EU.

•Machubu olondola osasoka onyamulira madzi othamanga kwambiri kapena ngati zida zamakina (monga ma bearing housings).

Zinthu Zazikulu Zomwe Zikuyendetsa Bwino Msika wa ku Ulaya

1. Kutsatira Malamulo ndi Chitetezo: Muyezo wa EN 10216 ukugwirizana kwambiri ndi European Pressure Equipment Directive (PED 2014/68/EU). Kugwiritsa ntchito zipangizo zogwirizana ndi muyezo uwu ndi chinthu chofunikira kwambiri kuti opanga aziyika zida pamsika waku Europe mwalamulo, zomwe S355J2H imapereka umboni wamphamvu woti zikutsatira malamulo.

2. Kapangidwe Kabwino Kwambiri ka Makina: Kuphatikiza koyenera kwa mphamvu ndi kulimba kumathandiza kuti ikwanitse kuthana ndi nyengo zosiyanasiyana ku Europe komanso malo ovuta a mafakitale.

3. Ubwino ndi Kutsata Zinthu: Opanga ndi ogwiritsa ntchito aku Europe amayamikira kwambiri chitsimikizo cha khalidwe. Muyezo wa EN 10216 umafuna kuwongolera mwamphamvu kupanga, kuyesa, ndi kutsimikizira, kuonetsetsa kuti zinthu zonse ndi zabwino kwambiri komanso kuti zinthuzo zitsatidwe bwino.

4. Unyolo Wogulitsa Zinthu ndi Ukatswiri: Europe ili ndi opanga machubu achitsulo otsogola padziko lonse lapansi (monga Tenaris, Vallourec, ndi ena omwe ali ndi kupezeka kwakukulu) ndi maukonde ogawa, omwe amatha kupereka machubu a S355J2H mokhazikika m'njira zosiyanasiyana komanso kupereka chithandizo chokwanira chaukadaulo.

Mapeto

Chitoliro chachitsulo chosasunthika cha EN 10216 S355J2H sichingokhala chinthu chogulitsidwa; ndi "mtsempha" ndi "msana" wa zomangamanga zamakono zamafakitale ku Europe. Kupambana kwake kumachokera ku kuphatikiza kwangwiro: dongosolo lolimba la ku Europe lomwe limafotokoza bwino kwambiri, komanso mphamvu zake zazikulu, kulimba kwambiri, komanso kudalirika kwakukulu komwe kumakwaniritsa zofunikira kwambiri zamagawo akuluakulu amafakitale ku Europe. Pamene Europe ikupitilizabe kuyika ndalama mu kusintha kwa mphamvu, kukweza zomangamanga, ndi kupanga zatsopano, chubu chachitsulo chosasunthika cha S355J2H mosakayikira chidzakhalabe chinthu chofunikira kwambiri, chothandizira zamakono komanso zamtsogolo zamafakitale aku Europe.
