高壓油管膠管上的字條4SH-DN25-I.D-1"-DIN-EN856-W.P. 380BAR-B.P. 22040PSI是什么意思
DIN-EN856 4SH,德國標(biāo)準(zhǔn)四層鋼絲纏繞高壓液壓膠管
DN25,內(nèi)徑25mm
1",1英寸
W.P. 就是工作壓力的簡稱,Working Pressure
380BAR,工作壓力為380BAR
B.P. 就是爆破壓力的簡稱,Burst Pressure
22040PSI,爆破壓力為22040PSI
壓力換算值:1Mpa=10公斤=10BAR=145PSI
爆破壓力為工作壓力的4倍
爆破壓力22040PSI=380BAR*4*145PSI
