Core Application Scenarios
Lub Tsev Txheej Txheem
Dynamic Load Pipe Trusses: Hoobkas seismic thav duab, chaw ntau pob ru tsev (yuav tsum muaj ntau tshaj los yog sib npaug rau 27J cuam tshuam lub zog ntawm 20℃los xyuas kom meej weld toughness)
Pem Teb Txhawb Cov Yeeb Nkab: Siv cov yas deformation los nqus cov khoom thauj (~ 15% tus nqi qis dua piv rau ASTM A36 welded yeeb nkab)
Foundation Engineering Connectors
ASTM A252 Tube Pile Welded Circumferential Seams(raws li cov ntsiab lus ua ntej):
Lub ntsiab Piles: A252 Gr.3 (Yield Ntau dua lossis sib npaug rau 414 MPa, seamless / ncaj- seam welded yeeb nkab)
Connector Rings： Q235B welded yeeb nkab (235 MPa tawm los, dynamic load toughness compatibility)
Cov khoom siv thauj tog rau nkoj bolt lub tes tsho (kev pabcuam temp. Ntau dua lossis sib npaug ntawm -20 degree, hloov SS400 yeeb nkab)
Cov Khoom Siv Hluav Taws Xob Tubular Cheebtsam
Engineering machinery hydraulic brackets (tsis yog- qhov chaw thauj khoom tseem ceeb, xws li excavator boom liner kav)
Cia khib uprights (zoo li qub load scenarios, nto galvanized rau corrosion tiv thaiv)
Transmission Tower Structural Pipes(Kev pabcuam temp.> -20 degree, welds xav tau UT tshuaj xyuas)
