Mipope yachitsulo yopanda msoko imagwira ntchito yofunika kwambiri pantchito zamafakitale, ndiEN 10210ndi EN 10216 ndizomwe zimadziwika bwino mumiyezo yaku Europe, kulunjika mapaipi achitsulo osasunthika kuti agwiritsidwe ntchito motsatana.

EN 10210 muyezo
Zida ndi kapangidwe:
TheEN 10210muyezo umagwira ntchito pa mapaipi otentha opangidwa ndi zitsulo osasunthika pamapangidwe. Zida wamba ndi S235JRH, S275J0H,Chithunzi cha S355J2H, etc. Zigawo zazikulu za aloyi za zipangizozi zikuphatikizapo carbon (C), manganese (Mn), silicon (Si), etc. Zomwe zimapangidwira zimasiyanasiyana malinga ndi maphunziro osiyanasiyana. Mwachitsanzo, mpweya wa S355J2H sudutsa 0.22%, ndipo manganese ali pafupifupi 1.6%.

Kuyang'anira ndi zinthu zomalizidwa:
EN 10210mapaipi achitsulo amayenera kuyesedwa mwamphamvu ndi zida zamakina, kuphatikiza kulimba kwamphamvu, kulimba kwapang'onopang'ono komanso kuyesa kwakutali. Kuphatikiza apo, kuyezetsa kulimba kwamphamvu kumafunika kuti zitsimikizire kuti zikuyenda bwino m'malo otentha. Chomalizidwacho chiyenera kukumana ndi kulekerera kwapamwamba ndi zofunikira zapamwamba zomwe zimatchulidwa muyeso, ndipo pamwamba pake nthawi zambiri imakhala ndi dzimbiri.

EN 10216 muyezo
Zida ndi kapangidwe:
Muyezo wa EN 10216 umagwira ntchito pamapaipi achitsulo opanda msoko kuti agwiritse ntchito kukakamiza. Zida zodziwika bwino zimaphatikizapo P235GH, P265GH, 16Mo3, ndi zina zotero. Zidazi zimakhala ndi zinthu zosiyanasiyana zopangira alloying. Mwachitsanzo, P235GH ili ndi mpweya wosapitirira 0.16% ndipo imakhala ndi manganese ndi silicon; 16Mo3 ili ndi molybdenum (Mo) ndi manganese, ndipo imakhala ndi kutentha kwakukulu.

Kuyang'anira ndi zinthu zomalizidwa:
TS EN 10216 mapaipi achitsulo amayenera kudutsa njira zingapo zowunikira, kuphatikiza kusanthula kwa kapangidwe ka mankhwala, kuyesa kwazinthu zamakina ndi kuyesa kosawononga (monga kuyezetsa akupanga ndi X-ray). Chitoliro chachitsulo chomalizidwa chiyenera kukwaniritsa zofunikira za kulondola kwazithunzi ndi kulolerana kwa makulidwe a khoma, ndipo nthawi zambiri zimafuna kuyesa kwa hydrostatic kuti zitsimikizire kudalirika kwake m'madera ovuta kwambiri.

Chidule
TheEN 10210ndi TS EN 10216 miyezo yamapaipi achitsulo opanda msoko ndi mapaipi achitsulo opangidwa ndi kukakamiza, motsatana, kuphimba zinthu zosiyanasiyana komanso zofunikira. Kupyolera mu kufufuza mosamala ndi kuyesa njira, mawonekedwe a makina ndi kudalirika kwa mapaipi achitsulo amatsimikiziridwa. Miyezo iyi imapereka maziko odalirika pakusankhidwa kwa mipope yachitsulo m'mafakitale osiyanasiyana, kuonetsetsa chitetezo ndi kukhazikika kwa polojekitiyi.
