Metal-composite corrugated hoses and a process for manufacturing the same |
摘要 |
A metal-composite corrugated hose having a wall including a metal layer forming its innermost layer and a resin layer surrounding it. Its wall has in its corrugated portion a metal layer thickness (A) of at least 20 mu m, but below 200 mu m, and a resin layer thickness (B) of 80 to 5,000 mu m. Each thickness of A and B has a ratio (A:B) of 1:4 to 1:50. The hose is made by a specific process in which the metal and resin layers are not corrugated simultaneously. Thus, there is a provided a metal-composite corrugated hose having high fuel impermeability, flexibility and strength, and having a reinforcing effect sufficient to protect the metal layer from any fatigue failure. |
