1. Hoʻopuka pōkole o ka pā kila S355J0W:
ʻO S355J0W ka mea kila maʻamau maʻamau o ʻEulopa, nona ka pā kila kū i ka wā.He kila haʻahaʻa haʻahaʻa i hana ʻia ma ka hoʻohui ʻana i kekahi mau mea hoʻohui i ke kila maʻamau.ʻO ke kūpaʻa corrosion o ka lewa o ke kila hoʻoheheʻe he 2-8 mau manawa o ke kila kalapona maʻamau, a loaʻa iā ia nā waiwai mechanical maikaʻi, nā waiwai welding, a me nā mea ʻē aʻe, a ʻoi aku ka lōʻihi o ka manawa, ʻoi aku ka maopopo o ka hopena kūʻē corrosion.
2. S355J0W i hoʻomaikaʻi ʻia i ke kila pale ʻana i ka lewa
Hoʻohui ʻia kekahi mau mea hoʻohui i ke kila, e like me P, Cu, Cr, Ni, Mo, i mea e hoʻonui ai i ke kū'ē ʻana i ka ea corrosion, a ma lalo o ka mana o nā kūlana climatic, e hana hou ʻia kahi oxide pale ma ka metala kumu.
3. Ke kūlana hoʻouna o S355J0W:
Hāʻawi ʻia i loko o ka ʻōwili wela, maʻamau a i ʻole ʻōwili maʻamau.
ʻEhā, S355J0W paʻa kila kila maʻamau maʻamau:
Hoʻohana ʻo S355J0W i ka maʻamau EN10025-5: 2004.
5. S355J0W i hoʻomaikaʻi ʻia i ke kila pale ʻana i ka lewa
Hoʻohui ʻia kekahi mau mea hoʻohui i ke kila, e like me P, Cu, Cr, Ni, Mo, i mea e hoʻonui ai i ke kū'ē ʻana i ka ea corrosion, a ma lalo o ka mana o nā kūlana climatic, e hana hou ʻia kahi oxide pale ma ka metala kumu.
6. ʻO kā mākou lako lako:
1. Loaʻa ʻia nā mea kikoʻī o ka pā kila: mānoanoa 8-700mm, ākea 1500-4020mm, lōʻihi 4000mm-17000mm, ʻāpana kaumaha a hiki i 30.00 tons.Loaʻa nō hoʻi nā pā kila nui ma ke noi.
2. Nāʻano o nā papa kila i loaʻa: nā papa kila kalapona, nā papa kila ikaika kiʻekiʻe, nā papa kila no nā alahaka, nā papa kila no nā hale kūkulu hale, nā papa kila no ka hana moku a me nā paepae waho, nā papa kila no nā paila a me nā moku kaomi, ke kila. nā papa no nā mold, nā papa kila no nā hale hoʻoheheʻe, He 12 mau ʻāpana o nā papa kila no nā pipelines aila a me ke kinoea, ikaika ikaika a paʻakikī kiʻekiʻe, nā papa kila corrosion, a me nā papa kila composite, me ka ʻoi aku o 300 home a nā hōʻailona haole.
3. Loaʻa no nā koi ʻike kīnā, Z15-Z35 mānoanoa kuhikuhi hana koi, ikaika kiʻekiʻe a me nā koi ikaika a me nā papa kila ʻē aʻe.
4. Hiki ke hoʻolakoʻia e like me nā kūlana aupuni, nā kūlana metallurgical, nā kūlanaʻAmelika AISI / ASME / ASTM, Japanese JIS, German standard DIN, French NF, British BS, European EN, international ISO a me nā kūlana'ē aʻe.
