Multi-layer expandable hose

An expandable hose assembly that is able to expand one or more of longitudinally along the length-wise axis of the hose between hose ends and radially, to an expanded state in response to application of at least a minimum fluid pressure to an inner tube of the hose. Once the fluid pressure falls below the minimum fluid pressure, the hose will contract. The hose includes a thermoplastic elastomer inner layer and a slip coating layer thereon having lubricating properties that increases the life of the hose assembly. The hose assembly can include an outer sheath or covering that covers the inner tube and slip coating layer. 种可膨胀软管组件，响应于向软管的内管至少施加最小流体压力，该可膨胀软管组件可在沿软管端头之间的软管的纵长轴线的纵向上以及径向上中的者或多者膨胀至膨胀状态。旦流体压力降到所述最小流体压力之下，软管将收缩。所述软管包括热塑性弹性体内层和在其上的具有增加该软管组件寿命的润滑性能的滑爽涂层。该软管组件可包括覆盖所述内管和滑爽涂层的外护套或覆盖件。
