    Abstract: An improved coiled air brake tubing is formed from a nylon polyurethane laminate. The laminate includes an innermost nylon layer surrounded with a thick intermediate polyurethane layer in turn covered with an outermost thin nylon layer. The polyurethane layer is fiber reinforced. The product is extruded and coiled around a heated mandril causing it to assume a coiled set. This exhibits improved low temperature properties and is less expensive than a nylon product.

    Abstract translation: 改进的卷绕空气制动管由尼龙聚氨酯层压板形成。 该层压体包括最后的尼龙层,其被厚的中间聚氨酯层包围,然后又覆盖有最外层的薄尼龙层。 聚氨酯层是纤维增强的。 产品被挤出并卷绕在加热的心轴周围,使其呈现卷曲组。 这表现出改善的低温性能并且比尼龙产品便宜。
