He kūlana koʻikoʻi nā paipu kila ʻole i ka ʻoihana hou a hoʻohana nui ʻia i ke kūkulu ʻana, ka hana ʻana i nā mīkini, petrochemical a me nā ʻano ʻē aʻe.EN 10210ʻO nā paipu kila maʻemaʻe ʻole no nā hale, ʻo ia ka BS EN 10210-1 kahi kikoʻī kikoʻī no nā mea hao ʻole i hoʻopaʻa ʻia i ka wela a me nā kila kila maikaʻi. ʻO nā māka maʻamau i kēia maʻamau ka S235GRH, S275JOH, S275J2H, S355JOH a me S355J2H.

ʻO ka mea mua, ʻo S235GRH kahi kila kila kumu, hoʻohana nui ʻia no nā ʻāpana hana ma lalo o ke kaumaha haʻahaʻa a me ka lumi wela o ka lumi. Me ka ikaika hua o 235MPa, loaʻa iā ia ka weldability maikaʻi a me ke ʻano anuanu, a kūpono ia no ka hana maʻamau a me nā hale mechanical.

A laila ʻo S275JOH a me S275J2H. He paʻakikī maikaʻi ʻo S275JOH ma -20 ℃ a me ka ikaika hua o 275MPa, a hoʻohana mau ʻia no ke kūkulu ʻana i nā hale a me nā papahana alahaka me nā haʻahaʻa haʻahaʻa. ʻOi aku ka maikaʻi o ka paʻakikī o ka S275J2H ma -20 ℃, a kūpono i nā ʻāpana kūkulu e koi ai i kahi kumu palekana kiʻekiʻe.

S355JOHaS355J2Hhe mau kila ikaika. ʻO S355JOH ka paʻakikī maikaʻi loa ma ka lumi wela a me ka haʻahaʻa haʻahaʻa (-20 ℃), me ka ikaika o ka hua o 355MPa, a hoʻohana nui ʻia i nā hana hoʻolālā kiʻekiʻe a me nā hana koʻikoʻi, e like me nā hale kiʻekiʻe a me nā alahaka nui. Loaʻa i ka S355J2H ka paʻakikī o ka hopena ma -20 ℃, a kūpono i nā wahi anu a i ʻole nā ​​papahana e koi ana i ka hōʻoia palekana.

ʻO ka maʻamau EN 10210 ʻaʻole i wehewehe wale i ka haku mele a me nā waiwai mechanical o nā paipu kila, akā hāʻawi pū i nā koi kikoʻī no ka hoʻomanawanui dimensional, ka maikaʻi o ka ʻili, ka hoʻāʻo ʻole luku, a me nā mea ʻē aʻe. hoʻohana.

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

Ma keʻano laulā, hōʻike ʻia nā paipu kila ʻole i hana ʻia e like me nā kūlana EN 10210 i ka hana maikaʻi loa i ke kūkulu ʻana a me nā kahua ʻoihana. ʻO nā paipu kila o nā māka e like me S235GRH, S275JOH, S275J2H, S355JOH, a me S355J2H i ko lākou mau hiʻohiʻona ponoʻī a hiki ke hoʻokō i nā pono o nā papahana like ʻole. ʻAʻole hoʻomaikaʻi wale kā lākou noi ākea i ka maikaʻi a me ka palekana o nā papahana, akā hoʻolaha pū i ka hoʻomohala ʻana a me ka hana hou o ka ʻenehana mea kila.
