EN 10210 S355J2Hhe kila hollow pauku hana wela e like meEN 10210me ka ikaika haʻahaʻa haʻahaʻa o 355 MPa (no ka mānoanoa o ka pā ≤ 16 mm) a me nā waiwai hopena maikaʻi ma nā haʻahaʻa haʻahaʻa a hiki i -20 ° C, e lilo ia i mea kūpono no ka hoʻohana ʻana i kahi ākea o nā hale a me nā ʻenekinia.
ʻAe, EN 10210 =BS EN 10210.
Ua like ka BS EN 10210 a me EN 10210 i ka ʻike loea a ua hōʻike ʻelua i nā kūlana ʻEulopa no ka hoʻolālā, hana ʻana a me nā koi no nā ʻāpana hollow structural thermoformed.
ʻO BS EN 10210 ka mana i hoʻopaʻa ʻia ma UK, ʻoiai ʻo EN 10210 kahi maʻamau ākea ʻEulopa.Hiki i nā hui hoʻonaʻauao aupuni ʻokoʻa ke kau mua i ka maʻamau me nā pōkole ʻāina kikoʻī, akā mau ka ʻike kumu o ka maʻamau.
Hiki ke hoʻokaʻawale ʻia nā ʻāpana hollow ma ke ʻano he poepoe, square a rectangular, a elliptical paha.
No ka mea he kaʻina hana wela e like me EN 10210, hiki ke hoʻohana ʻia ka pōkole aʻe.
HFCHS= pauku pōʻai pōʻai wela wela；
HFRHS= ʻāpana ʻāpana wela wela a i ʻole ʻāpana ʻehā;
HFEHS= pauku elliptic hollow wela.
Poe: ʻO ke anawaena o waho a hiki i 2500 mm;
ʻO ka mānoanoa o ka pā a hiki i 120 mm.
ʻOiaʻiʻo, ʻaʻohe ala e hana ai i nā paipu o kēia nui a me ka mānoanoa o ka paia inā hoʻohana ʻia ke kaʻina hana kuʻi ʻana o ERW.
Hiki iā ERW ke hana i nā paipu a hiki i ka 660mm me ka mānoanoa o ka pā o 20mm.
Hiki ke hana ʻia ke kila ma o ahili ʻole a i ʻole ka wiliwili ʻanakaʻina hana.
Mawaena o nakaʻina hana wili, nā kaʻina hana kuʻihao maʻamauERW(kuʻi kuʻekuʻe uila) aSAW(kuʻi ʻia arc submerged).
Ma waena o nā mea ʻē aʻe,ERWhe hana kuʻikuʻi e hoʻohui i nā ʻāpana metala ma o ka wela pale a me ke kaomi.Hoʻohana ʻia kēia ʻenehana i kahi ākea o nā mea a me nā mānoanoa a hiki ke hana i kahi kaʻina hana wili.
SAW, ma ka ʻaoʻao ʻē aʻe, he ala wili e hoʻohana ai i ka flux granular e uhi i ke arc, e hāʻawi ana i ke komo hohonu a me ka maikaʻi weld maikaʻi a kūpono loa no ka wili ʻana i nā papa mānoanoa.
ʻO ka mea aʻe, ʻo ke kaʻina hana ERW, kahi ʻenehana hana maikaʻi loa i hoʻohana nui ʻia e hana i kahi ākea o nā paipu kila a me nā profiles.
Pono e hoʻomaopopo ʻia no nā ʻāpana ʻāwī ʻole a me ka palaoa maikaʻi i hana ʻia e ke kaʻina hana kuʻi, ʻaʻole ʻae ʻia nā welds hoʻoponopono koe wale nō ka wili arc submerged.
Nā mea maikaʻi JR, JO, J2 a me K2 - wela wela,
ʻAʻole paʻa ka ikaika haʻahaʻa haʻahaʻa o ka paipu kila S355J2H, e hoʻololi ia me ka mānoanoa o ka pā.
Ma keʻano kiko'ī, ua hoʻonohonohoʻia ka ikaika o ka S355J2H e like me ke kūlana i ka emiʻana o ka mānoanoa o ka paia ma mua o 16mm, akā i ka piʻiʻana o ka mānoanoa o ka pā, e emi iho ka ikaika o ka hua, no lailaʻaʻole hiki i nā paipu kila S355J2H a pau ke hiki i ka liʻiliʻi loa. ikaika o 355MPa.
