Ntim Ntawm Carbon Steel Pipe
Raws li cov yeeb nkab nominal loj (NPS) thiab cov neeg siv khoom xav tau, peb muab peb txoj hauv kev ntim khoom hauv qab no:
Hexagonal Bundling- Rau qhov nruab nrab thiab me me (NPS 1/8" - 8")
Ntim cov ntsiab lus: Ntau txoj hlua khi yog nqa tawm nrog cov hlua hlau, thiab qhov hnyav ntawm txhua pob khoom feem ntau yog tswj ntawm 2,000kg - 3,000kg kom yooj yim hoisting.
Hoisting reinforcement: Nylon slings tuaj yeem muab ntxiv rau ntawm txoj haujlwm khi, uas yooj yim rau kev thauj khoom ncaj qha ntawm qhov chaw nres nkoj thiab zam kev puas tsuaj rau cov yeeb nkab lub cev los ntawm kev sib cuag ncaj qha ntawm cov hlau xaim hlua.
Kev Tiv Thaiv: Cov txheej txheej txheej ntawm txhua pob ntawm cov kav dej tuaj yeem muab qhwv nrog cov hnab ntim dej tsis muaj dej kom tiv thaiv cov ntsev tsuag xeb thaum lub sijhawm thauj mus los hauv hiav txwv.
Loose Packing- Rau cov kab loj loj (NPS 10 "thiab siab dua)
Kev them nyiaj yug: Internal bracing tuaj yeem ntsia tau rau hauv cov yeeb nkab kom tsis txhob loj - txoj kab uas hla nyias- cov kav dej uas muaj phab ntsa tawm ntawm - ntawm - puag ncig deformation thaum lub sij hawm stacking thiab tsheb thauj mus los.
Stacking: Dunnage yog muab tso rau hauv qab thiab nruab nrab ntawm cov khaubncaws sab nraud povtseg tiv thaiv kev sib txhuam ncaj qha ntawm cov hlau.
Ntoo Crate Ntim rau cov kav dej tshwj xeeb- Rau siab -precision / me me phab ntsa thickness kav
Muaj feem cuam tshuam: Xws li ASTM A179 cov raj xa hluav taws xob kub thiab txias - kos cov kav dej.
