He mea koʻikoʻi nā paipu kila maʻemaʻe i nā ʻoihana ʻoihana, aEN 10210a me EN 10216 ʻelua mau kikoʻī maʻamau i nā kūlana ʻEulopa, e kuhikuhi ana i nā paipu kila ʻole no ka hoʻohana ʻana i ka hoʻolālā a me ke kaomi.

EN 10210 Kūlana
Mea a me ka haku mele:
ʻO kaEN 10210pili ka maʻamau i nā paipu kila ʻole i hana ʻia me ka wela no nā hale. Loaʻa nā mea maʻamau S235JRH, S275J0H,S355J2H, etc. ʻO nā mea hoʻohui nui o kēia mau mea he kalapona (C), manganese (Mn), silicon (Si), a me nā mea'ē aʻe. Eia kekahi laʻana,ʻaʻole iʻoi aku ka nui o ke kalapona o S355J2H i ka 0.22%, aʻo ka manganese ma kahi o 1.6%.

Nānā a me nā huahana i pau:
EN 10210Pono nā paipu kila e hana i nā ho'āʻo waiwai mechanical, e like me ka ikaika tensile, ka ikaika hua a me nā ho'āʻo elongation. Eia kekahi, koi ʻia nā hoʻokolohua paʻakikī e hōʻoia i ka hana ma nā wahi wela haʻahaʻa. Pono ka huahana i hoʻopau ʻia e hoʻokō i nā hoʻomanawanui dimensional a me nā koi o ka maikaʻi o ka ʻili i hōʻike ʻia ma ka maʻamau, a ʻo ka ʻili ke kūpaʻa maʻamau.

EN 10216 Kūlana
Mea a me ka haku mele:
Pili ka EN 10216 i nā paipu kila ʻole no ka hoʻohana ʻana i ke kaomi. Loaʻa nā mea maʻamau i ka P235GH, P265GH, 16Mo3, a me nā mea ʻē aʻe. Eia kekahi laʻana, loaʻa iā P235GH kahi kalapona iʻoi aku ma mua o 0.16% a loaʻa i ka manganese a me ke silika; Aia ka 16Mo3 i ka molybdenum (Mo) a me ka manganese, a ʻoi aku ka nui o ka pale wela.

Nānā a me nā huahana i pau:
Pono nā paipu kila EN 10216 e hele i kahi ʻano o nā kaʻina loiloi koʻikoʻi, me ka nānā ʻana i ka haku mele, ka hoʻāʻo waiwai mechanical a me ka hoʻāʻo ʻole luku (e like me ka hoʻāʻo ultrasonic a me ka hoʻāʻo X-ray). Pono ka paipu kila i hoʻopau ʻia i nā koi o ka pololei dimensional a me ka mānoanoa o ka paia, a koi pinepine i ka hoʻāʻo hydrostatic e hōʻoia i kona hilinaʻi i nā kaiapuni kiʻekiʻe.

Hōʻuluʻulu manaʻo
ʻO kaEN 10210ʻO nā kūlana EN 10216 no nā paipu kila liʻiliʻi no nā paipu kila a me ke kaomi ʻana, e uhi ana i nā ʻano mea like ʻole a me nā koi. Ma o ka nānā pono a me nā kaʻina hana hoʻāʻo, e hōʻoia ʻia nā waiwai mechanical a me ka hilinaʻi o nā paipu kila. Hāʻawi kēia mau kūlana i kahi kumu hilinaʻi no ke koho ʻana i nā paipu kila ma nā ʻoihana ʻoihana like ʻole, e hōʻoiaʻiʻo ana i ka palekana a me ka paʻa o ka papahana.
