Hauv kev sib tw ntawm kev tsheb ciav hlau, perforated rears thiab tsis-perforated sib txawv ntawm ob qho tib si muaj kev ua yeeb yam, kev ua yeeb yam, sib tham sib txawv engineering xav {}}
Cov kev sib tw perforated tau muab nrog cov tw kub rau ntawm cov duav, cov ciav hlau muaj zog rau kev lag luam kev sib tw, hauv kev lag luam metall loads . peri perforated rail tau nrawm dua los tiv thaiv cov kev cuam tshuam nrog kev ntxhov siab thiab kev sib tsoo, thiab yuav tsum muaj kev tshuaj xyuas lub tsheb thiab cov kab nrib pleb
Qhov tsis-perforated rail bolels lub qhov teeb meem tsim thiab yog tsim nyog rau kev sib tw sib tw thiab lwm yam kev xav tau ntawm cov kev sib tw thiab lwm yam kev xav tau rau smoothness thiab ruaj khov. Nyob rau hauv high-ceev rail rail rail ntawm cov kab ciav hlau siab, tsis muaj qhov sib tw tau welded rau hauv cov kab ke, thiab kev txhawb nqa lub suab nrov thiab kev txhawb nqa kev ua haujlwm siab ncaj qha cuam tshuam rau lub neej pabcuam ntawm lub Ntsia .
Thaum xaiv cov hlua perforated lossis tsis yog qhov tsim nyog kom muaj kev sib zog ua ke nrog kev ua kom zoo nkauj rau cov khoom lag luam zoo nkauj, thiab cov kev ua haujlwm zoo li qub Kev Thauj Mus Los .
