膠管內徑要適當。管(guan)徑過小會加大(da)管(guan)路內介質的(de)(de)流速，使(shi)系統發熱，降低效率，而且會產生過大(da)的(de)(de)壓(ya)力降，影(ying)響整個系統的(de)(de)性能。若膠(jiao)管(guan)采用(yong)管(guan)夾固定或(huo)膠(jiao)管(guan)穿過鋼板等間(jian)隔物(wu)時，也要注意(yi)膠(jiao)管(guan)的(de)(de)外徑尺寸。因此膠(jiao)管(guan)使(shi)用(yong)壽命(ming)長短，不僅決(jue)定于(yu)質量的(de)(de)好壞，同時也決(jue)定于(yu)正確使(shi)用(yong)保養。所以即使(shi)產品有(you)極高的(de)(de)質量，如不能正確地使(shi)用(yong)和(he)保養，也會嚴重(zhong)影(ying)響其使(shi)用(yong)質量和(he)壽命(ming)，甚至發生不應有(you)的(de)(de)嚴重(zhong)事故，對財物(wu)造成損(sun)失。
