摘要： High flow capacity corrugated coilable dual wall plastic pipe having improved longitudinal flexibility and a bend radius sufficient to permit coiling and plowing of such pipe into the ground using automated installation equipment. The coilable dual wall pipe has an outer corrugated wall formed of a thermoplastic material such as high density polyethylene, and an inner smooth wall formed of a different more flexible and resilient thermo-bondable material that has an enhanced strain capacity and lower modulus of elasticity. The inner wall material also has enhanced mechanical properties which generally improve processing and help prevent excessive drag and tearing of the liner material during the manufacturing process. Suitable material blends for the inner wall incorporating a thermoplastic elastomer additive in combination with a thermoplastic material have proven suitable in providing the required longitudinal flexibility and pipe bend radius to permit the desired pipe coiling and plow installation without failure.

摘要翻译： 高流量波纹可卷绕的双壁塑料管具有改进的纵向柔性和足够的弯曲半径，以允许使用自动安装设备将这种管线卷绕和犁耕到地面中。 可卷曲的双壁管具有由诸如高密度聚乙烯的热塑性材料形成的外部波纹壁，以及由不同的更柔性和弹性的热粘合材料形成的内部光滑壁，其具有增强的应变能力和较低的弹性模量。 内壁材料还具有增强的机械性能，其通常改善加工并且有助于防止衬垫材料在制造过程中的过度拖曳和撕裂。 已经证明适用于将热塑性弹性体添加剂与热塑性材料结合在一起的用于内壁的合适的材料共混物可提供所需的纵向柔性和管道弯曲半径，以允许期望的管道卷取和犁式安装而不会发生故障。
