LSAW Steel Yeeb Nkab Pile ASTM A252 - Hwm Foundation Solution rau North American Infrastructure
Product Overview
Peb muab siab - zoo LSAW (Longitudinally Submerged Arc Welded) steel yeeb nkab pawg tsim rau lubASTM A252, ASTM A252tus qauv, qhov tseeb specification rau piling daim ntawv thov thoob plaws hauv lub tebchaws United States thiab Canada. Tsim los pab txhawb kev sib sib zog nqus, peb cov kav dej yog qhov kev xaiv zoo tshaj plaws rau cov pej xeem hnyav, dej hiav txwv, thiab cov khoom siv uas thauj khoom -cov kabmob muaj peev xwm thiab kev ncaj ncees tsis yog- sib tham.
Vim li cas thiaj xaiv LSAW rau Piling?
Tsis zoo li kauv (SSAW) lossis ERW kav, peb cov LSAW pawg siv Submerged Arc welded txheej txheem, uas tso cai rau cov phab ntsa hnyav dua thiab zoo dua qub. Qhov no ua rau lawv zoo tagnrho rau "kev tsav tsheb nyuaj" uas tau ntsib nyob rau hauv cov av ntom ntom lossis bedrock. Lawv muab kev ua tau zoo tshwj xeeb hauv:
◇◆◇ Choj Foundations & Highway Overpasses
◇◆◇ Marine Terminals, Wharves, thiab Ports
◇◆◇ Offshore Cua thiab Mooring Structures
◇◆◇ Siab -Rise Building Deep Foundations
Specifications & Mechanical Properties
Peb cov khoom lag luam tuaj yeem taug qab tau tag nrho rau lub tshuab steel, kom ntseeg tau tias ua raws li ASTM A252 Qib 3 (qib feem ntau rau siab -cov haujlwm muaj peev xwm).
● Txuj:ASTM A252, ASTM A252
○ Khoom siv:GR1, GR2, GR3.
● Txheej txheem:LSAW (Longitudinal Submerged Arc Vuam).
○ Out Diameter Range:8 ''-72 '' (219-1800mm).
● Phab ntsa Thickness:Txog li 50 hli (Kev cai hnyav- cov ntu phab ntsa muaj los tiv thaiv buckling thaum tsav tsheb).
○ Xaus Xaus:Bevelled rau thaj chaw vuam lossis qhov kawg kawg.
Quality Assurance
Txhua cov yeeb nkab yuav raug soj ntsuam nruj. Peb tuaj yeem muab EN 10204 3.1/3.2 ntawv pov thawj thiab kev xeem ua pov thawj los ntawm thib peb- cov koom haum (xws li Lloyds, DNV, lossis ABS) kom ua tau raws li North American qhov project specifications . Peb pawg yog engineered los pab txhawb axial compression, nro, thiab lateral loads, kom ntseeg tau lub neej ntev ntawm koj infrastructure.
Kev Tshawb Fawb & Kev Tshawb Fawb
Xyoo 2023, ib tus neeg cog lus marine hauv Louisiana tau muab1,200 tons ntawm ASTM A252 Qib 3 LSAW pawg(36 "inch) rau qhov chaw nres nkoj kho dua tshiab.
"Peb xaiv cov LSAW pawg no vim tias lawv tau ua haujlwm siab tsav tsheb zoo dua li ERW lwm txoj kev. Cov phab ntsa tuab zoo ib yam, thiab cov bevelled xaus haum zoo kawg nkaus nrog peb lub sijhawm vuam. Txhua Daim Ntawv Pov Thawj Zeb tau muab tsis tau ncua -raws li tus engineer xav tau. Tus khub txhim khu kev qha rau cov txheej txheem tseem ceeb."
