Expansion joints |
摘要 |
The proximate ends of spaced apart sections of duct systems for fluid media are interconnected by expansion joints having a sleeve of flexible material surrounding and isolating the flow path in the area between the sections. The flexible material consists of at least one reinforcing substrate to which surface layers of a media resisting material having a degree of elasticity are fused and bonded. Each substrate in one embodiment consists of two series of strands oriented to present a criss-cross pattern with the strands of both series diagonally disposed with with respect to the flow path when the material is formed into a sleeve. In another embodiment, there is an additional series of strands which are longitudinal.
