Q235B/Q355B Icyuma gifunga icyuma kandi kidapfa amazi

Igishushanyo: Ikirundo cy'icyuma gihuza, ubushobozi bwo kwinjira ≤1×10⁻⁷ cm/s

Amerika: Yujuje ibipimo bya ASTM D5887 kugira ngo agakoresho ko mu mazi gagabanuke munsi y'ingoma

Aziya y'Amajyepfo y'Uburasirazuba: Amazi yo hasi ashobora kunyura mu bihe by'imvura yo mu turere dushyuha

Uburyo bwo gukora icyuma gikozwe mu byuma bya Q235B/Q355B

1. Guhitamo ibikoresho fatizo– Hatoranywa uduce tw'icyuma twiza cyane dufite imiterere ihamye y'imiti.

2.Gukora ibicurane– Imirongo y'icyuma iragoramye neza kandi ikazungurutswa mu bwoko bwa U, ubwoko bwa Z, cyangwa Larssen ku bushyuhe bw'icyumba.

3.Kugorora no Gukata– Ibirundo biragororwa kandi bigacibwa ku burebure busabwa hamwe n’uburyo bwo kwihanganira ibintu neza.

4. Ubuvuzi bw'ubuso– Hakoreshwa uburyo bwo kurangiza urusyo, galvanized, cyangwa coated kugira ngo habeho kurwanya ingese.

5. Igenzura ry'Ubuziranenge– Imiterere ya shimi, imiterere ya mekanike, n'ubuziranenge bw'ibipimo biragenzurwa.

6. Gupakira no Gutanga– Bihurijwe hamwe mu mutekano kandi byoherezwa ahantu nyaburanga ku isi.

Uburyo bwo gukora icyuma gikozwe mu buryo bw'icyuma

Ubuso bw'urukuta rw'icyuma rwa Q235B/Q355B

Amerika:HDG nka ASTM A123 (agapira ka zinc kari munsi ya ≥ 85 µm); irangi rya 3PE ni amahitamo; irangi ryose rikurikiza RoHS.

Aziya y'Amajyepfo y'UburasirazubaUbunini bwa galvanized ishyushye ni hollyh (irenga 100μm), kandi hashyirwamo ibice bibiri bya epoxy coal tar, ishobora gusukwaho umunyu ikageragezwa amasaha 5000 nta ngese, niyo nziza cyane mu bidukikije byo mu nyanja.

UBUSABIZI

1. Inyubako y'Icyuma cy'Icyambu: Gusaba kubaka inkuta z'icyambu, icyambu n'urukuta rw'ikirahure, imbaraga zidasanzwe zo gushyigikira inyubako no kuramba mu bidukikije byo mu mazi.

2. Ikirundo cy'icyuma cyo kurinda uruzi: Yakozwe kugira ngo ikomeze ishingiro ry'inkombe z'imigezi, ivure isuri kandi irinde ingaruka z'amazi atemba n'umwuzure w'imigezi.

3. Ikirundo cy'icyuma gishingiye ku kiraro: Bikwiriye gukoreshwa mu kubaka urufatiro rw'ikiraro kugira ngo haboneke urufatiro rwimbitse n'ubwubatsi buhamye mu gihe cy'inyubako nyinshi.

4. Ikirundo cy'icyuma cyo munsi y'ubutaka: Ikoreshwa mu mazu yo munsi y'ubutaka, mu tunnel no mu nyubako zo munsi y'ubutaka kugira ngo ibungabunge ubutaka kandi ibushyigikire mu buryo bwizewe.

Ikirundo cy'icyuma gishyushye gifite ishusho ya U (5)

Kuki wahitamo icyuma cy'ubushinwa cy'ubwami ku byuma bicukurwamo amabati
