Qaab-dhismeedka Birta Mareykanka ASTM A572 I

Sharaxaad Gaaban:

ASTM I-beam waa nooc ka mid ah birta qaab-dhismeedka kaas oo leh shabakad toosan oo ku taal bartamaha isku xirta laba diyaaradood oo jiif ah labada dhinacba. Waxay leedahay saamiga xoogga iyo miisaanka oo aad u fiican, awood qaadis culays oo wanaagsan waana fududahay in la sameeyo, taas oo ay ugu wacan tahay isticmaalka ballaaran ee dhismaha dhismayaasha, buundooyinka iyo warshadaha.

3) Waxaa baaraya hay'ado awood leh sida CCIC, SGS, BV, iyo TUV, iyadoo la adeegsanayo baakado caadi ah oo badda ku habboon.

Xirmooyinka iyo Gaarsiinta

Baakad
Ilaalin Buuxda: Alwaaxyada I-ga waxaa lagu duubay tarpaulin oo ay weheliyaan 2-3 baakadood oo biyo-mareen ah; go'yaal tarpaulin ah oo kulaylka xira, oo roobka u adkaysta ayaa ka hortagaya qoyaanka inuu galo.

Xirmo Ammaan ah: Xirmo kasta waxaa lagu duubay suuman bir ah oo 12-16 mm ah; waxay u fududahay 2-3 tan iyo qalabka qaadista ee la jaan qaadi kara Mareykanka.

Calaamadaynta Hufnaanta: Calaamadaha laba-luqadlaha ah (Ingiriis iyo Isbaanish) oo leh darajo, qeexitaanno, koodhka HS, lambarka dufcadda iyo tixraaca warbixinta imtixaanka.

Ilaalin heer sare ah: I-beams ≥800 mm ayaa lagu daaweeyay saliid isku-dhafan ka dibna laba jeer ayaa lagu duubay tarpaulin.

Bixinta
Maraakiib la isku halleyn karo: Iskaashiga shirkadaha ugu fiican (MSK, MSC, COSCO ect) si loo hubiyo rarida badbaadada.

Xakamaynta Tayada: Nidaamka ISO 9001; Alwaaxyada si adag ayaa loo xakameeyaa laga bilaabo baakadaha ilaa gaadiidka si loo hubiyo inay si fiican u yimaadaan, taasoo kuu oggolaanaysa inaad yeelato mashruuc aan dhibaato lahayn.

Xalka Gaadiidka Suuqa Ameerika: ASTM I Beams waxaa ugu horreyn loo dhoofiyaa Ameerika iyada oo loo marayo xamuulka badda ee konteenarrada ku jira oo leh xarig bir ah, ilaalin dhammaadka, iyo daaweyn ikhtiyaari ah oo ka hortagga miridhku si loo hubiyo gaadiid badbaado leh oo hufan.

Su'aalaha Badiya La Weydiiyo

S: Waa maxay heerarka I-beam-kaaga ee Bartamaha Ameerika?
A: I Beams-keena wuxuu u hoggaansamayaa ASTM A36 & A572 Fasalka 50 kaas oo ku habboon Bartamaha Ameerika. Waxa kale oo suurtogal ah in la keeno badeecooyin buuxiya heerarka qaranka (tusaale ahaan, MEXICO NOM).

S: Intee in le'eg ayay qaadanaysaa in la geeyo Panama?
J: Waqtiga Gaadiidka Maraakiibta Badda ee ka timaadda Dekadda Tianjin ilaa Aagga Ganacsiga Xorta ah ee Colon 28-32 maalmood toddobaad. Soo saarista iyo keenista guud ahaan waa 45-60 maalmood. Gaarsiinta degdegga ah sidoo kale waa la diyaarin karaa.

S: Ma ka caawisaa nadiifinta kastamka?
J: Haa, dilaaliintayada xirfadlayaasha ah ayaa sameyn doona bayaanka kastamka, bixin doona canshuurta iyo dhammaan shaqada warqadda ah si loo hubiyo in gaarsiintu si habsami leh u socoto.
