S355 JR kauv hlau yeeb nkabStrength thiab Versatility
S355 JR kauv steel yeeb nkabyog tsim los siv cov thev naus laus zis siab thiab cov hlau zoo los ua ke lub zog thiab ntau yam hauv ib yam khoom.Cov kav dej no tau tsim los tiv thaiv kev kub ntxhov, ua rau lawv haum rau ntau yam kev siv.Txawm hais tias siv los thauj dej, roj lossis roj av, cov kav dej no muaj kev ua haujlwm tsis zoo thiab ua haujlwm ntev.
Cov qauv muaj zog thiab kev ua haujlwm ruaj khov
Ib qho tseem ceeb tshaj plaws ntawm S355 JR kauv steel yeeb nkab yog nws cov kev tsim kho ruaj khov, uas ua kom muaj kev ncaj ncees.Cov kav dej no muaj cov hlua khi hlua khi uas ua kom lub zog siab tshaj plaws thaum txo qhov kev pheej hmoo ntawm kev xau lossis tsis ua haujlwm.Qhov kev tsim kho tshiab no ua rau lub raj xa dej tuaj yeem tiv taus cov khoom hnyav thiab cov huab cua hnyav, ua rau nws zoo tagnrho rau kev tsim kho vaj tse xws li txuas hniav, tunnels thiab cov tsev siab.

Hydrostatic Test
Txhua qhov ntev ntawm cov yeeb nkab yuav tsum raug kuaj los ntawm cov chaw tsim khoom mus rau lub siab hydrostatic uas yuav tsim nyob rau hauv cov yeeb nkab phab ntsa ib qho kev ntxhov siab tsis pub tsawg tshaj 60% ntawm qhov tsawg kawg nkaus yield zog ntawm chav tsev kub.Lub siab yuav tsum txiav txim siab los ntawm qhov sib npaug hauv qab no:
P = 2st/D
Permissible variations In Weights and Dimensions
Txhua qhov ntev ntawm cov yeeb nkab yuav tsum tau ntsuas nyias thiab nws qhov hnyav yuav tsum tsis txhob sib txawv ntau dua 10% tshaj lossis 5.5% raws li nws qhov hnyav, suav nrog nws qhov ntev thiab nws qhov hnyav ntawm ib chav tsev ntev.
