马牌钢丝缠绕胶管结构和规格（英文版）说明

Product Structure

Product Structure: consists of an inner tube, middle rubber layer, two, four or six spiral wire reinforcements and 

cover. Inner tube is to transmit liquid under pressure and protect steel wire against corrosion while cover is 

to protect wire against damage. Wire layer (ф0.3-2.0 reinforcement) is the structure materials that providing 

reinforcement. 

Application
