Dinani batani la kumanja
1. Maziko a MakomaMaziko a makoma a pansi pa nyumba zazitali, mafakitale, nyumba zosungiramo katundu, zamalonda kapena nyumba zogona. Maziko a mulu woyenera mitundu yonse ya nyumba.
2. Maziko a Milu ya Mlatho: Maziko onyamula katundu a milatho yamisewu ikuluikulu, njanji ndi milatho ya m'mizinda. Maziko a mtsinje wa nzimbe, lacustrine, ndi milu ya m'nyanja.
3. Kumanga Madoko: Maziko onyamula katundu wa malo oimikapo doko, malo osungiramo sitima, ndi malo oimikapo doko. Makina olemera ndi zida zonyamulira katundu padoko.
4. Mapulojekiti a Uinjiniya wa Zam'madzi ndi Mphamvu ya Mphepo ya M'mphepete mwa Nyanja: Maziko a ma turbine amphepo a m'mphepete mwa nyanja. Kapangidwe Kothandizira Mapulatifomu a M'mphepete mwa Nyanja, Mapaipi a M'mphepete mwa Nyanja, Makoma a M'nyanja, ndi zina zotero. Kukana mafunde, kukana mafunde ndi kukana dzimbiri m'nyanja.
5. Uinjiniya Waukulu Waukulu, Milu Yaikulu Yautali:Ntchito zazikulu zauinjiniya wa zomangamanga (monga madamu, malo osungiramo zinthu pansi pa nthaka, ndi ngalande) zomwe zimafuna maziko akuya pogwiritsa ntchito milu yayikulu. Thandizo la katundu wa mafakitale, makina ndi zomangamanga.
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:Zingwe zachitsulo kuti zikhale zosavuta kuzigwira. Mabuloko a matabwa kapena dunnage amaikidwa pakati pa milu kuti atetezedwe ku kuwonongeka akamanyamula. Kukonza pamwamba (ngati mukufuna): Utoto wakuda, mafuta a dzimbiri, filimu ya pulasitiki. Milu ya galvanized yotentha ingaphimbidwenso ndi filimu yoteteza pamwamba kwakanthawi. Tikhozanso kupereka ma CD okonzedwa mwamakonda.
2. Kutumiza:Kutalika kwa stoke wamba: 6m, 12m. Kutalika koyenera malinga ndi ntchito yanu. Koyenera mayendedwe apanyanja, sitima ndi pamsewu. Nthawi yopangira nthawi zambiri imakhala masiku 15-30 mutalandira malipiro, kutumiza msanga malinga ndi kuchuluka ndi zofunikira. Koyenera kutumiza kunja padziko lonse lapansi ndi zikalata zonse (satifiketi yowunikira, mndandanda wolongedza, bilu ya katundu).
Njira Zodzitetezera:
1. Crane kapena forklift yokhala ndi ma sling kapena slingshoes iyenera kugwiritsidwa ntchito kuti chitoliro chisawonongeke mu Handling Peoperties.
2. Sungani malo ozizira, ouma komanso opumira mpweya kuti musunge, apo ayi dzimbiri lidzayamba kuonekera musanayike. Pa ma phukusi akuluakulu/olemera kwambiri, chonde tsatirani malamulo a kutumiza katundu m'deralo mosamala.
1. Kodi mapaipi achitsulo a ASTM A252 Giredi 3 ndi chiyani?
Mapaipi achitsulo a ASTM A252 grade 3Mapaipi achitsulo opangidwa ndi chitsulo cholumikizidwa kuti agwiritsidwe ntchito ngati maziko olimba pansi pa nyumba, milatho, madoko, ndi mainjiniya akunja. Pali njira ziwiri zolumikizira mapaipi awa: chitoliro cholumikizira cha helical submerged arc welding (SSAW) kapena chitoliro cholumikizira cha longitudinal submerged arc welding (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.
