Dinani batani la kumanja
1. Maziko a Khoma la Pansi:Maziko ozama a nyumba zazitali, mafakitale, nyumba zosungiramo katundu, nyumba zamalonda ndi nyumba zokhalamo. Maziko ozungulira (oyenera mitundu yonse ya nyumba).
2. Maziko a Milu ya Mlatho:Maziko onyamula katundu a milatho yamisewu ikuluikulu, milatho ya sitima, ndi misewu yodutsa m'matauni. Ikani maziko a milatho yodutsa mitsinje, nyanja, ndi milatho yowoloka nyanja.
3. Kumanga Madoko:Maziko onyamula katundu wa malo oimikapo doko, malo osungiramo sitima, ndi malo oimikapo doko. Zipangizo zolemera ndi malo osungira katundu wa doko.
4. Mapulojekiti a Mphamvu ya Mphepo ya M'nyanja ndi Uinjiniya wa Zam'madzi:Maziko a ma turbine amphepo akunyanja. Kapangidwe kothandizira mapulatifomu akunyanja, mapaipi akunyanja, makoma a nyanja, ndi zina zotero. Kukana mafunde, kukana mafunde, ndi kukana dzimbiri la m'nyanja.
5. Uinjiniya Waukulu Wanyumba:Maziko akuya okhala ndi milu yayikulu ya mainchesi a ntchito zazikulu zauinjiniya (monga madamu, malo osungiramo zinthu pansi pa nthaka, ndi ngalande). Thandizo la makina amafakitale ndi katundu womangidwa.
1) Ofesi ya Nthambi - chithandizo cha Chisipanishi, chithandizo cha msonkho, ndi zina zotero.
2) Matani opitilira 5,000 a katundu alipo, okhala ndi makulidwe osiyanasiyana
3) Kuyang'aniridwa ndi mabungwe odalirika monga CCIC, SGS, BV, ndi TUV, ndi ma CD oyenera kuyenda panyanja
1. Ma CD:Chingwe chachitsulo kuti chigwiritsidwe ntchito mosavuta.
Matabwa kapena dunnage zimayikidwa pakati pa milu kuti zisawonongeke panthawi yonyamula.
Chitetezo cha pamwamba (ngati mukufuna): Utoto wakuda, mafuta oletsa dzimbiri, kapena mipukutu ya filimu ya pulasitiki.
Milu ya galvanized yoviika m'madzi otentha ikhoza kukhala ndi filimu yoteteza kwakanthawi kuti isakhwime pamwamba.
Ma phukusi opangidwa mwamakonda amapezeka mukawapempha.
2. Kutumiza:Kutalika kwa katundu wamba: mamita 6 ndi mamita 12. Kutalika kwapadera kulipo kuti kukwaniritse zofunikira pa polojekiti yanu.
Yoyenera kuyenda panyanja, pa sitima, kapena pamsewu.
Nthawi yotumizira nthawi zambiri imakhala masiku 15-30 mutatsimikizira kulipira, kutengera kuchuluka ndi zomwe zafotokozedwa.
Yoyenera kutumiza kunja padziko lonse lapansi, yokhala ndi zikalata zonse (satifiketi yoyendera, mndandanda wolongedza, chikalata chonyamulira katundu).
3. Kusamalira Machenjezo:Gwiritsani ntchito crane kapena forklift yokhala ndi ma sling kapena ma sling kuti mupewe kusintha kwa chitoliro.
Sungani pamalo ozizira, ouma, komanso opumira bwino kuti dzimbiri lisadzachite dzimbiri musanayike.
Pa kutumiza kwakukulu/kolemera kwambiri, chonde tsatirani malamulo a m'deralo otumizira katundu.
1. Kodi ndi chiyaniMapaipi achitsulo a ASTM A252 Giredi 3?
Mapaipi achitsulo a ASTM A252 a giredi 3 ndi mapaipi achitsulo olumikizidwa kuti agwiritsidwe ntchito ngati maziko olimba pansi pa nyumba, milatho, madoko, ndi mainjiniya akunja. Pali njira ziwiri zolumikizira mapaipi awa: chitoliro cholumikizira cha arc chozungulira (SSAW) kapena chitoliro cholumikizira cha arc chozungulira (LSAW/EFW).
2. Kodi pali kukula ndi kutalika kotani komwe kulipo?
Chipinda chakunja: 219 mm - 3000 mm (XXL/kukula kwakukulu kwa chipindacho kulipo) Kukhuthala kwa khoma: 6-40 mm. Kutalika kwa zinthu zokhazikika ndi mamita 6 ndi mamita 12, ndipo kutalika kwapadera kungaperekedwe ngati mukufuna.
3. Kodi miyezo ya zinthu ndi makhalidwe a makina ndi ati?
Muyezo Wofunika: ASTM A252 Giredi 3
Mphamvu Yotulutsa: ≥345 MPa
Mphamvu yokoka: 455~620 MPa
Kutalika: ≥20%%
4. Kodi ndingapeze satifiketi yaubwino ndi malipoti owunikira?
Inde, mapaipi onse achitsulo ali ndi satifiketi ya ISO 9001. Zikalata zonse zofunika kuphatikiza malipoti a chipani chachitatu ochokera ku SGS, BV kapena bungwe lina lovomerezeka.
5. Kodi mapaipi achitsulo amapakidwa bwanji?
Amamanga mapaipi achitsulo ndi bandeji yachitsulo ndikupatula ndi matabwa osawonongeka. Zophimba/kukulunga kapena/ndi mankhwala opangidwa pamwamba omwe atchulidwa pamwambapa akulimbikitsidwa malinga ndi zomwe zalembedwa. Mapaketi opangidwa mwamakonda akupezeka.
6. Kodi nthawi yoperekera ndi yotani?
Nthawi yotumizira: Masiku 15-30 pambuyo pa chitsimikizo cha oda (zimadalira kuchuluka, kufotokozera ndi komwe mukupita).
7. Kodi n'zotheka kusintha kukula kwake?
Inde, kukula kwa khoma ndi mainchesi ake kungasinthidwe malinga ndi zosowa za makasitomala.
