Nūhou - Pehea e koho ai i U Channel Steel no ke kūʻai ʻana a me ka hoʻohana ʻana?

E wehewehe i ke kumu a me nā koi

Ke kohoU-channel kila, ʻo ka hana mua e wehewehe i kāna hoʻohana kikoʻī a me nā koi koʻikoʻi:

Aia kēia me ka helu pono ʻana a i ʻole ka loiloi ʻana i ka haʻahaʻa kiʻekiʻe e pono ai ke kūpaʻa (ka ukana static, ka ukana dynamic, ka hopena, a me nā mea ʻē aʻe), ka mea e hoʻoholo pololei i nā kikoʻī a me nā ana (ke kiʻekiʻe, ka laulā wāwae, ka mānoanoa pūhaka) a me ka pae ikaika; ka hoʻomaopopo ʻana i kāna mau hiʻohiʻona hoʻohana (e like me ke kūkulu ʻana i nā beams/purlins, nā papa mechanical, nā kākoʻo laina conveyor, nā papa a i ʻole nā mea hoʻonaninani), ʻokoʻa nā hiʻohiʻona like ʻole i ka ikaika, rigidity, precision a me ka helehelena; e noʻonoʻo ana i ka hoʻohana ʻana (i loko/waho, inā he humid, corrosive media), ka mea e hoʻoholo ai i nā koi anti-corrosion (e like me ka hot-dip galvanizing, pena kiʻi) a i ʻole ke koi ʻia ke kila / stainless steel; ka wehewehe ʻana i ke ʻano pili (weld a bolting), e pili ana i ka hoʻolālā ʻana o ka wāwae (e koi ʻia ka papa welding flat a i ʻole nā puka i mālama ʻia) a me nā koi no ka weldability material; i ka manawa like, pono e hōʻoia i nā palena nui o ka wahi hoʻonohonoho (lōʻihi, kiʻekiʻe, ākea) a me nā lula kikoʻī a i ʻole nā kūlana ʻoihana e pono ai ka papahana e hoʻokō i nā mea i koho ʻia e hoʻokō i nā pono palekana a me nā pono hana.

U Channel Steel Specifications, Ana a me na mea

1. Nā kikoʻī
Kūlana ʻEulopaKaila UPNua kapa ʻia nā kumu hoʻohālike ma muli o ko lākou kiʻekiʻe pūhaka (unit: mm). Loaʻa iā lākou kahi ʻāpana ʻāpana U a me nā ʻāpana koʻikoʻi:

Kiʻekiʻe pūhaka (H): ʻO ke kiʻekiʻe holoʻokoʻa o ke kahawai. No ka laʻana, ʻo ke kiʻekiʻe o ka pūhaka o UPN240 he 240 mm.

Laulā pūʻali (B): ʻO ka laulā o ka flange. No ka laʻana, loaʻa i ka UPN240 kahi band 85 mm.

Mānoanoa pūhaka (d): Ka mānoanoa pūnaewele. No ka laʻana, ʻo ka UPN240 ka mānoanoa pūhaka o 9.5 mm.

Mānoanoa pūnaʻi (t): ʻO ka mānoanoa flange. No ka laʻana, he 13 mm ka mānoanoa o ka UPN240.

Kaumaha manaʻo no ka mika: ʻO ke kaumaha o kēlā me kēia ʻāpana lōʻihi (kg/m). No ka laʻana, he 33.2 kg/m ke kaumaha o ka UPN240.

Nā kikoʻī maʻamau (nā ʻāpana ʻāpana):

kumu hoʻohālike	kiʻekiʻe pūhaka (mm)	laula wāwae (mm)	Mānoanoa pūhaka (mm)	Mānoanoa wāwae (mm)	Kaumaha manaʻo no ka mika (kg/m)

2. ʻAno mea
Pono nā mea kila ala UPN e hoʻokō i ke kūlana ʻEulopa EN 10025-2. Aia nā koho maʻamau:
(1) Mea maʻamau
S235JR: ʻO ka ikaika ≥ 235MPa, ke kumu kūʻai haʻahaʻa, kūpono no nā hale static (e like me nā kākoʻo māmā).
S275JR: ʻO ka ikaika ≥ 275MPa, ka ikaika kaulike a me ka hoʻokele waiwai, hoʻohana ʻia no nā papa hale maʻamau.
S355JR: ʻO ka ikaika ≥ 355MPa, koho mua no ka ukana kiʻekiʻe, kūpono no nā hiʻohiʻona koʻikoʻi kiʻekiʻe e like me nā mīkini awa a me nā kākoʻo alahaka. ʻO kona ikaika tensile hiki i 470 ~ 630MPa, a he haʻahaʻa haʻahaʻa haʻahaʻa maikaʻi.
(2) Nā mea kūikawā
Ke kila ikaika kiʻekiʻe: e like me S420/S460, i hoʻohana ʻia no nā lako mana nuklea a me nā kumu mīkini ultra-kaumaha (e like me UPN350).
ʻO ke kila welu: e like me S355J0W, kūpaʻa i ka corrosion o ka lewa, kūpono no nā alahaka waho.
ʻO ke kila kila: hoʻohana ʻia i nā wahi corrosive e like me ke kemika a me ke kai, akā me ke kumukūʻai kiʻekiʻe.

(3) Lapaʻau ʻili

ʻeleʻele wela: ka ʻili paʻamau, pono ka mālama anti-corrosion ma hope.

ʻO ka galvanizing hot-dip: galvanized layer ≥ 60μm (e like me ke kaula hao no nā kākoʻo kiʻi paipu), hoʻomaikaʻi i ka pale ʻana i ka corrosion.

3. Manao koho

Nā hiʻohiʻona haʻahaʻa kiʻekiʻe (e like me ka port crane rails): E hana mua i nā mea UPN300~UPN350 + S355JR e hōʻoia i ka pale ʻana a me ka ʻili.

Kaiapuni ʻino: E hui pū me ka galvanizing wela a i ʻole hoʻohana pono i ke kila weluwelu.

Nā koi māmā: UPN80 ~ UPN120 moʻo (mika kaumaha 8.6 ~ 13.4kg / m), kūpono no nā pale pale pale a me nā kākoʻo paipu.

'Ōlelo Aʻo: I ke kūʻai ʻana, pono e hōʻoia i ka hōʻike waiwai (e like me EN 10025-2) a me ka hoʻomanawanui dimensional (EN 10060) e hōʻoia i ka hoʻokō ʻana o ka papahana.

ʻO ka manaʻo ʻōlelo a ka mea hana Kanal U hilinaʻi-Royal Group

At Hui Alii, He hoa alakaʻi mākou ma ka ʻoihana kalepa ʻoihana metala o Tianjin. Me ka ʻoihana a me ka hoʻokō i ka hoʻokumu ʻana i ka maikaʻi, ua hoʻokumu mākou iā mākou iho ʻaʻole wale i ke kila U-like, akā i nā huahana ʻē aʻe a pau.

ʻO kēlā me kēia huahana i hāʻawi ʻia e Royal Group e hana i kahi kaʻina nānā koʻikoʻi koʻikoʻi e hōʻoia i ka hoʻokō a ʻoi aku paha i nā kūlana kiʻekiʻe loa. Kōkua kēia iā mākou e hāʻawi i kā mākou mea kūʻai aku i nā huahana hilinaʻi a palekana i kūpono no nā ʻano noi like ʻole.

Hoʻomaopopo mākou ʻo ka manawa ka mea nui no kā mākou mea kūʻai aku, a no laila, mākaukau mau kā mākou limahana a me nā ʻauwaʻa kaʻa e hoʻopuka i nā waiwai. Ma ka hōʻoia ʻana i ka wikiwiki a me ka manawa, kōkua mākou i kā mākou mea kūʻai aku e mālama i ka manawa a hoʻopaʻa i kā lākou hana kūkulu.

ʻAʻole lawe wale ʻo Royal Group i ka hilinaʻi i ka maikaʻi o ka huahana a me ka waiwai, akā hōʻike pū kekahi i ka ʻoiaʻiʻo i kā mākou pilina mea kūʻai. ʻAʻole mākou e hāʻawi wale i nā ʻano like ʻole o ke kila U, akā he nui nā huahana ʻē aʻe, e like me ke kila H-like, ke kila I-like, a me ke kila C-like, e hoʻokō i nā pono like ʻole o nā mea kūʻai aku ma ka ʻāina.

ʻO kēlā me kēia kauoha i kau ʻia me ka Royal Group e nānā ʻia ma mua o ka uku. He kuleana ko nā mea kūʻai aku e nānā i kā lākou huahana ma mua o ka uku ʻana e hōʻoia i ka ʻoluʻolu a me ka maikaʻi o ka huahana.a
