ʻO ka wehewehe pōkole:

Hoʻopili kā mākou huahana i nā kūlana ʻEulopa a ua hoʻokumu ʻia ke anu, ʻaʻole koi i ka mālama wela ma hope, e hōʻoia ana i ka ikaika maikaʻi a me ka lōʻihi. Ua ʻike ʻia ka papa S235JRH no kāna weldability maikaʻi loa a me ka hoʻohālikelike ʻana, e kūpono ana ia no nā noi hoʻolālā kahi koʻikoʻi ka hilinaʻi a me ka hana.

FAQ

Q1. He aha ka EN 10219 S235JRH?

EN 10219 paipuHe kūlana ʻEulopa e hōʻike ana i nā kikoʻī no nā ʻāpana hollow welded welded anu. Hoʻohana nui ʻia ia i ka ʻoihana kūkulu ma muli o kāna mau waiwai mechanical maikaʻi loa a me ka weldability.

Q2. He aha nā pōmaikaʻi o ka hoʻohana ʻana iā S235JRH?

ʻO ke kila S235JRH ka ikaika kiʻekiʻe, ka ductility maikaʻi a me ka weldability maikaʻi loa, kūpono no nā ʻano hana like ʻole. ʻAe ʻia kona mau mea anuanu no nā ana kikoʻī a hoʻemi i ke kaumaha.

Q3. He aha nā noi i kūpono i ka S235JRH?

Hoʻohana pinepine ʻia kēia mea i ke kūkulu ʻana i nā hale, nā alahaka, a me nā hale ʻē aʻe kahi koʻikoʻi ka ikaika a me ka hilinaʻi.

Q4. Pehea e hiki ai iaʻu ke hōʻoia e loaʻa iaʻu ka S235JRH kiʻekiʻe?

Ke hana pū nei me kahi mea hoʻolako kaulana, e like me kā mākou hale hana ma Cangzhou, e hōʻoia e loaʻa iā ʻoe kahi huahana e hoʻokō i nā koi koʻikoʻi o ka maʻamau EN 10219.
