HFW Steel Yeeb Nkab Rau Choj Structure DN450 EN10210 S355JRH

S355JRH yog cov qauv hollow seem steel qib uas tau teev tseg hauv EN 10210, tsim los rau cov ntawv thov uas xav tau lub zog siab thiab zoo toughness. Cov khoom siv feem ntau muab qhov tsawg kawg nkaus lub zog ntawm kwv yees li 355 MPa, nrog lub zog tensile li ntawm 470 txog 630 MPa. Nws cov tshuaj muaj pes tsawg leeg yog ua tib zoo tswj, feem ntau txwv cov pa roj carbon monoxide nyob ib ncig ntawm 0.20 feem pua ​​​​thaum tuav cov ntsiab lus manganese ze li 1.50 feem pua, ua kom muaj qhov sib npaug zoo ntawm lub zog thiab weldability. Cov khoom no ua rau cov yeeb nkab tuaj yeem tiv taus cov loads cyclic, kev co, thiab kev ntxhov siab ib puag ncig feem ntau ntsib hauv cov qauv choj.

Huayang Steel Pipes tsim DN450 HFW cov kav dej siv cov khoom siv siab tshaj - zaus vuam tshuab, ua kom muaj kev sib txuas txuas ntxiv thiab tsis sib xws nrog kev sib txuas ntawm cov hlau. Precision forming thiab sizing txheej txheem tswj kom raug sab nraud txoj kab uas hla thiab zoo ib yam phab ntsa thickness raws cov yeeb nkab lub cev. Txhua cov yeeb nkab tau txais kev soj ntsuam ntawm vuam seam ultrasonic, kev tshuaj xyuas qhov ntev, thiab kev kuaj xyuas tshuab kom ua tau raws li cov qauv kev tsim vaj tsev. Rau kev siv choj, kev kho deg ntxiv xws li galvanizing lossis hnyav-cov dej num tiv thaiv- cov txheej txheem corrosion feem ntau yog siv los txhim kho cov kav ntev thiab txuas ntxiv lub neej kev pab cuam nyob rau hauv ib puag ncig sab nraum zoov.
