Plastic-lined composite pipe

The invention discloses a plastic-lined composite pipe which comprises an inner pipe layer, a base material layer and an outer pipe layer, the base material layer is located between the inner pipe layer and the outer pipe layer, the base material layer is provided with holes used for combining the inner pipe layer and the outer pipe layer into a whole, and the base material layer is provided with a hole net layer used for improving strength. The hole net layer covers the holes. According to the plastic-lined composite pipe, the hole net layer is additionally arranged, so that the overall compression resistance and explosion resistance of the base material layer are improved, the situation that the plastic-lined composite pipe is broken or burst is reduced or avoided, and the application range is widened. 本发明公开了一种衬塑复合管材，包括内管层、基材层和外管层，所述基材层位于所述内管层和所述外管层之间，所述基材层上设置用于使所述内管层和所述外管层结合为一体的孔，所述基材层上设置用于增加强度的孔网层，且所述孔网层将所述孔覆盖。本发明通过增设孔网层以增加基材层整体的抗压、抗暴强度，减少或者避免了衬塑复合管材断裂或者爆裂情况的发生，扩大了使用范围。
