Ukupakisha Nokulethwa

1. Ukupakisha Okuchwepheshile
Ukupakisha Okuphephile: Ibhande lensimbi elinamandla aphezulu elinesivikelo somphetho sokuvikela ukuguqulwa kwe-flange.

Ukuvimbela Ukugqwala: Umkhiqizo oqediwe ugoqwe ngokuphelele ezikhwameni zepulasitiki ezingangeni manzi/ezilukiwe ezinezikhwama zangaphakathi zokususa umswakama ezifakiwe.

Ukulandeleka okuphelele: inqwaba ngayinye inamathegi ensimbi amelana nesimo sezulu Inombolo Yokushisa, Ibanga (Gr.50) kanye nosayizi.

2. Ukuthunyelwa Okuthuthukisiwe
Ukulayisha Isitsha:
I-20GP: Ifanele ubude obungu-5.8m.
40HC: Yenzelwe ubude obungu-11.8m/12m (Kunconywa kakhulu kumaphrojekthi amakhulu).
Izindlela ezikhethekile: Izitsha ezivulekile ukuze kube lula ukufinyelela i-crane noma i-Breakbulk ukuze kutholakale amathoni amaningi.

3. Ukuthunyelwa Kwempahla Kwesifunda
Ukusuka endlini kuya kwenye: Amahhovisi ethu ase-USA naseGuatemala aletha nge-flatbed ngqo endaweni yakho yokwakha.
Ukuqinisekiswa Kobuqotho: Ukwethulwa kwe-dunnage (amabhlogo enkuni) phakathi kwezinqwaba ukuze kugwenywe ukugoba ngesikhathi sokufakwa kanye nokuthuthwa.

Imibuzo Evame Ukubuzwa

Q1: Iyini insimbi ye-ASTM A36?
A: Insimbi ethambile yesakhiwo saseNyakatho Melika esetshenziswa kabanzi, enokushibilika okukhulu, ukwakheka nokuqina, esebenza njengensimbi yendawo yonke yokwakha kanye nezimo zezimboni.

UMBUZO 2: Umehluko phakathi kwesiteshi se-C kanye nesiteshi se-MC?
A: Iziteshi ze-C ezijwayelekile zinezingqimba zangaphakathi ezinciphile ezinobukhulu obujwayelekile baseMelika obungaguquki. Iziteshi ze-MC (ezihlukahlukene) zinezingqimba ze-flange ezenziwe ngokwezifiso kanye nobukhulu bewebhu ukuze kufakwe uhlaka olukhethekile kanye nezinhlelo zokusebenza ze-stair stringer. Zombili ziza ngebanga le-ASTM A36.

Q3: Ubukhulu obujwayelekile beziteshi ze-A36?
A: Ilawulwa yi-ASTM A6 standard, ukujula kusuka ku-3-intshi (C3) kuya ku-15-intshi (C15). Imithetho yokumaka usayizi: ukujula + isisindo ngonyawo (isb., C3×4.1, C8×11.5).

Umbuzo 4: Ingabe insimbi ye-ASTM A36 iyashiselelwa?
A: Yebo. Ikwazi ukushibilika kahle kakhulu. Izindlela ezivamile zokushibilika (i-SMAW, i-GMAW, i-oxyacetylene welding) ziyasebenza, ngaphandle kokushisa okwengeziwe noma ukufudumala ngemva kokushisa okudingekayo ukuze kube nobukhulu obujwayelekile.

Umbuzo 5: Ingabe iziteshi ze-A36 U zingagaywa?
A: Yebo. Njengoba insimbi yekhabhoni ivame ukugqwala, i-hot-dip galvanizing (ASTM A123) iyindlela eyinhloko yokwelapha ukumelana nokugqwala ezindaweni zangaphandle nezasolwandle.

Q6: Ungafunda kanjani i-A36 steel MTC?
A: I-EN 10204 3.1 MTC ejwayelekile ihlanganisa ukuqinisekiswa okuyinhloko oku-3: 1. Ukwakheka kwamakhemikhali (C, Mn, P, S, Si); 2. Izakhiwo zemishini: amandla okukhiqiza ≥36 ksi, amandla okudonsa 58–80 ksi, ukunwebeka ≥20%; 3. Ukulandeleka komkhiqizo ngenombolo yokushisa ehambisanayo.

Umbuzo 7: Ubude obujwayelekile bokuthumela ngaphandle?
A: Ngaphandle kobude obujwayelekile be-US obungu-20ft/40ft, osayizi abajwayelekile bokuthumela kwamanye amazwe bangu-5.8m/11.8m ukuze kulayishwe izitsha ezijwayelekile. Insizakalo yokusika ngokwezifiso nayo iyatholakala.

Umbuzo 8: Ukusetshenziswa okuvamile kweziteshi ze-A36?
A: Kusetshenziswa kabanzi ezakhiweni zokwakha, ama-lintels, izingxenye zamabhuloho, izithiyo zomgwaqo omkhulu, ama-trailer amaloli, izisekelo zemishini, imishini yezolimo kanye nezinhlelo zokufaka amandla elanga.
