Noho nā paipu kila humuhumu i kahi kūlana koʻikoʻi i ka ʻoihana hou a hoʻohana nui ʻia i ke kūkulu ʻana, ka hana mīkini, ka petrochemical a me nā ʻoihana ʻē aʻe.EN 10210kuhikuhi pono i nā paipu kila humuhumu no nā hale, ʻo ia hoʻi ʻo BS EN 10210-1 kahi kikoʻī no nā kila ʻole-alloy i ʻōwili wela ʻia a me nā kila kūkulu maikaʻi. ʻO nā māka maʻamau i loko o kēia kūlana e komo pū me S235GRH, S275JOH, S275J2H, S355JOH a me S355J2H.

ʻO ka mea mua, he kila papa kumu ʻo S235GRH, hoʻohana nui ʻia no nā ʻāpana kūkulu ma lalo o ke kaumaha haʻahaʻa a me ke kaiapuni mahana o ka lumi. Me ka ikaika hua o 235MPa, loaʻa iā ia ka hiki ke hoʻopili maikaʻi a me ke ʻano anu, a kūpono no ke kūkulu ʻana maʻamau a me nā hale mechanical.

ʻO ka mea aʻe ʻo S275JOH lāua ʻo S275J2H. He paʻakikī maikaʻi ko S275JOH ma -20℃ a he ikaika hua o 275MPa, a hoʻohana pinepine ʻia no nā hale kūkulu a me nā papahana alahaka me nā ukana waena. ʻOi aku ka paʻakikī o ka hopena o S275J2H ma -20℃, a kūpono ia no nā ʻāpana kūkulu e pono ai kahi kumu palekana kiʻekiʻe.

S355JOHa meS355J2Hhe mau kila ikaika kiʻekiʻe. Loaʻa i ka S355JOH ka paʻakikī maikaʻi loa ma ka mahana o ka lumi a me ka mahana haʻahaʻa (-20 ℃), me ka ikaika hua o 355MPa, a hoʻohana nui ʻia i nā papahana kūkulu koʻikoʻi a me ke kaumaha, e like me nā hale kiʻekiʻe a me nā alahaka nui. ʻOi aku ka paʻakikī o ka hopena o S355J2H ma -20 ℃, a kūpono no nā wahi anuanu loa a i ʻole nā ​​​​papahana e pono ai ka hōʻoia palekana hou aʻe.

ʻAʻole wale ka maʻamau EN 10210 e hoʻākāka pono i ka haku mele kemika a me nā waiwai mechanical o nā paipu kila, akā ke kau nei hoʻi i nā koi kikoʻī no nā ʻae ʻana o ka dimensional, ka maikaʻi o ka ʻili, ka hoʻāʻo ʻana ʻaʻole luku, a me nā mea ʻē aʻe. Hōʻoia kēia i ke kūlike a me ka hilinaʻi o nā paipu kila i ka wā o ka hana ʻana a me ka hoʻohana ʻana.

Hoʻokumu ʻia nā paipu kila humuhumu e ka ʻenehana ʻōwili wela, ka mea e hāʻawi iā lākou i nā waiwai mechanical maikaʻi loa a me ka pololei maikaʻi o ka dimensional. Hiki i ke kaʻina hana ʻōwili wela ke hoʻopau i ke kaumaha i loko o ka paipu kila, hoʻomaikaʻi i ka hoʻonohonoho ʻana o ke kila, a hoʻonui i kāna hana piha. Ke hoʻohālikelike ʻia me nā paipu kila i hoʻopaʻa ʻia, ʻoi aku ka kiʻekiʻe o nā paipu kila humuhumu i ka compressive, bending a me ka torsional ikaika, a kūpono no ke kākoʻo kūkulu a me ka halihali wai ma lalo o nā kūlana hana paʻakikī like ʻole.

Ma keʻano laulā, hōʻike nā paipu kila humuhumu i hana ʻia e like me nā kūlana EN 10210 i ka hana maikaʻi loa ma nā kahua kūkulu a me nā ʻoihana. Loaʻa i nā paipu kila o nā papa e like me S235GRH, S275JOH, S275J2H, S355JOH, a me S355J2H ko lākou mau ʻano ponoʻī a hiki ke hoʻokō i nā pono o nā papahana like ʻole. ʻAʻole wale kā lākou hoʻohana ākea e hoʻomaikaʻi i ka maikaʻi a me ka palekana o nā papahana, akā paipai pū kekahi i ka hoʻomohala ʻana a me ka hana hou ʻana o ka ʻenehana mea kila. He mea nui ke koho ʻana i nā paipu kila humuhumu o nā papa kūpono a me nā kikoʻī no ka hōʻoia ʻana i ka paʻa lōʻihi a me nā pono waiwai o nā papahana.
