EN 10210 S355J2Hhe maitai wāhanga tuwhera hanganga kua oti te whakamahana kia rite kiEN 10210me te kaha whakaputa iti rawa o te 355 MPa (mō ngā matotoru pakitara ≤ 16 mm) me ngā āhuatanga pānga pai i ngā pāmahana iti ki raro ki te -20°C, he mea tino pai mō te whakamahi i roto i te whānuitanga o ngā hanganga whare me ngā hanganga hangarau.
Āe, EN 10210 =Paerewa Paerewa EN 10210.
He ōrite te ihirangi hangarau o te BS EN 10210 me te EN 10210, ā, e tohu ana ēnei i ngā paerewa Pākehā mō te hoahoa, te hanga, me ngā whakaritenga mō ngā wāhanga tuwhera hanganga hanga-wera.
Ko te BS EN 10210 te putanga i whakamahia i te UK, ko te EN 10210 ia he paerewa whānui mō Ūropi. Tērā pea ka tāpirihia e ngā whakahaere paerewa ā-motu rerekē ngā whakarāpopototanga motuhake ki mua i te paerewa, engari he rite tonu te ihirangi matua o te paerewa.
Ka taea te whakarōpū i ngā wāhanga tuwhera he porowhita, he tapawhā, he tapawhā hāngai rānei, he porowhita rānei.
Nā te mea he tukanga wera kua oti i runga anō i te EN 10210, ka taea te whakamahi i te whakarāpopototanga e whai ake nei.
HFCHS= ngā wāhanga porowhita tuwhera kua oti te wera;
HFRHS= ngā wāhanga tapawhā, tapawhā rānei kua oti te whakamahana;
HFEHS= ngā wāhanga porotītaha wera kua oti te whakaoti.
Porowhita: Te whānui o waho tae atu ki te 2500 mm;
Te matotoru o te pakitara tae atu ki te 120 mm.
Ae, kāore he huarahi hei whakaputa ngongo o tēnei rahi me tēnei matotoru o te pakitara mēnā ka whakamahia te tukanga whakarewa ERW.
Ka taea e ERW te whakaputa ngongo tae atu ki te 660mm me te matotoru o te pakitara o te 20mm.
Ka taea te hanga maitai mā tehe hononga kore, he whakarewa rāneitukanga.
I roto i ngāngā tukanga whakarewa, ko ngā tikanga whakarewa noa koERW(whakarewa ātete hiko) meKĪHI(whakarewa pewa rukuhia).
I roto i ētahi atu,ERWHe tikanga whakarewa e hono ana i ngā wāhanga whakarewa mā te wera me te pēhanga ātete. Ka taea te whakamahi i tēnei tikanga ki te whānuitanga o ngā rauemi me ngā matotoru, ā, ka taea ai te tukanga whakarewa whai hua.
KĪHI, i tētahi atu ringa, he tikanga whakarewa e whakamahi ana i te rerenga kirikiri hei taupoki i te pewa, e whakarato ana i te urunga hohonu ake, me te kounga whakarewa pai ake, ā, he tino pai mō te whakarewa i ngā pereti matotoru.
Ko te tukanga ERW te mea e whai ake nei, he tikanga hanga tino whai hua e whakamahia whānuitia ana hei whakaputa i te whānuitanga o ngā ngongo me ngā kōtaha maitai.
Me mōhio hoki, mō ngā wāhanga tuwhera kore-konumohe, me ngā wāhanga pai-kikokore i hangaia mā te tukanga whakarewa, kāore e whakaaetia ngā whakarewa whakatika engari ko te whakarewa pewa i raro i te wai.
Ngā āhuatanga JR, JO, J2 me K2 - kua oti te whakamahana,
Kāore te kaha whakaputa iti rawa o te paipa maitai S355J2H i te pumau, ka rerekē i runga i te matotoru o te pakitara.
Ina koa, ka whakatakotoria te kaha whakaputa o te S355J2H kia rite ki te paerewa ina iti iho te matotoru o te pakitara i te 16mm, engari ina piki ake te matotoru o te pakitara, ka heke te kaha whakaputa, nō reira, kāore e taea e ngā paipa maitai S355J2H katoa te eke ki te kaha whakaputa iti rawa o te 355MPa.
