EN 10210 S355J2Hhe kila ʻāpana hakahaka i hoʻopau ʻia me ka wela e like meEN 10210me ka ikaika haʻahaʻa loa o 355 MPa (no nā mānoanoa o ka paia ≤ 16 mm) a me nā waiwai hopena maikaʻi ma nā mahana haʻahaʻa a hiki i -20°C, e kūpono ai no ka hoʻohana ʻana i nā ʻano hale like ʻole a me nā ʻenekinia.
ʻAe, EN 10210 =BS EN 10210.
Ua like ka BS EN 10210 a me EN 10210 ma ka ʻike loea a ke hōʻike nei lāua ʻelua i nā kūlana ʻEulopa no ka hoʻolālā, ka hana ʻana, a me nā koi no nā ʻāpana hakahaka hoʻonohonoho thermoformed.
ʻO BS EN 10210 ka mana i lawe ʻia ma UK, ʻoiai ʻo EN 10210 he kūlana maʻamau no ʻEulopa. Hiki i nā kino hoʻonohonoho kūlana aupuni like ʻole ke kau mua i ka kūlana me nā pōkole aupuni kikoʻī, akā mau nō ka ʻike nui o ke kūlana.
Hiki ke hoʻokaʻawale ʻia nā ʻāpana hakahaka i ke ʻano he poepoe, huinahā a ʻehā paha, a i ʻole elliptical.
Eia kekahi, no ka mea he hana wela ia e like me EN 10210, hiki ke hoʻohana ʻia ka huaʻōlelo pōkole ma lalo nei.
HFCHS= nā ʻāpana hakahaka poepoe i hoʻopau ʻia me ka wela;
HFRHS= nā ʻāpana hakahaka huinahā a ʻehā paha i hoʻopau ʻia me ka wela;
HFEHS= nā ʻāpana hakahaka elliptical i hoʻopau ʻia me ka wela.
Poepoe: Ke anawaena o waho a hiki i ka 2500 mm;
ʻO ka mānoanoa o ka paia a hiki i ka 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 hoʻoheheʻe ERW.
Hiki iā ERW ke hana i nā ʻōmole a hiki i ka 660mm me ka mānoanoa o ka paia o 20mm.
Hiki ke hana ʻia ke kila ma o kahiwili ʻole a i ʻole ka hoʻopili ʻanakaʻina hana.
Ma waena o nānā kaʻina hana kuʻihao, nā ʻano hana kuʻihao maʻamau e komo pū meERW(kuʻihao pale uila) a meʻIKE(kuʻihao arc i hoʻoluʻu ʻia).
Ma waena o nā mea ʻē aʻe,ERWhe ʻenehana kuʻihao ia e hoʻohui i nā ʻāpana metala ma o ka wela a me ke kaomi resistive. Hoʻohana ʻia kēia ʻenehana i nā ʻano mea like ʻole a me nā mānoanoa a hiki ai ke hana i kahi kaʻina hana kuʻihao kūpono.
ʻIKE, ma ka ʻaoʻao ʻē aʻe, he ʻano hana kuʻihao e hoʻohana ana i kahi flux granular e uhi i ke arc, ka mea e hāʻawi ana i ka komo hohonu a me ka maikaʻi o ka weld a kūpono loa no ka kuʻihao ʻana i nā papa mānoanoa.
ʻO ka mea aʻe, ʻo ke kaʻina hana ERW, he ʻenehana hana kūpono loa ia i hoʻohana nui ʻia e hana i nā ʻano paipu kila a me nā ʻaoʻao like ʻole.
Pono e hoʻomaopopo ʻia no nā ʻāpana hakahaka i hana ʻole ʻia a me nā ʻāpana hakahaka maikaʻi i hana ʻia e ke kaʻina hana kuʻihao, ʻaʻole ʻae ʻia nā kuʻihao hoʻoponopono koe wale nō ka kuʻihao arc i lalo o ka wai.
Nā ʻano JR, JO, J2 a me K2 - hoʻopau wela,
ʻAʻole paʻa ka ikaika hoʻohua haʻahaʻa loa o ka paipu kila S355J2H, e loli ia me nā mānoanoa o ka paia ʻokoʻa.
ʻO ke kikoʻī, ua hoʻonohonoho ʻia ka ikaika hua o S355J2H e like me ke kūlana i ka wā e emi ai ka mānoanoa o ka paia ma mua o 16mm a like paha, akā i ka wā e piʻi ai ka mānoanoa o ka paia, e hoʻemi ʻia ka ikaika hua, no laila ʻaʻole hiki i nā paipu kila S355J2H āpau ke hiki i ka ikaika hua liʻiliʻi loa o 355MPa.

ʻO ka paipu kila S355J2H kahi paipu kila kūkulu ikaika kiʻekiʻe me ka hana hoʻoheheʻe maikaʻi a me ka paʻakikī hopena haʻahaʻa, no laila he ākea ka hoʻohana ʻana i nā ʻano ʻoihana like ʻole.
