双扣聚乙烯增强管内壁不平坦的原因有哪些?

双扣聚乙烯增强管的使用规模越来越广,施工需求量增大,市场上许多质量低质的PE双壁波纹管也混入其间,牟取暴利,不会人员底子无法分辩,对客户形成很大的丢失。为使客户选购时不被遮盖,接下来就介绍一下双扣聚氯乙烯缠绕管内壁不平坦的缘由剖析
In the meantime, there will be more and more low-quality polyethylene pipes in the market due to the large-scale use of PE pipes and the increasing demand for polyethylene pipes in the market. In order to make customers not to be covered when purchasing, the next is to introduce the reason why the inner wall of double buckle PVC winding pipe is not flat
耐化学性:不被污水、废水及化学药品腐蚀,不被土壤中腐烂的物质腐蚀。
Chemical resistance: it is not corroded by sewage, waste water and chemicals, and is not corroded by rotten substances in soil.
抗冲击性:管壁为“工”字结构,耐冲击,高刚性;中空壁缠绕管属柔性管,延伸性好,地基下沉管材也不会破裂。
Impact resistance: the pipe wall is of I-shaped structure, impact resistant and high rigidity; the hollow wall winding pipe is a flexible pipe with good extensibility, and the pipe will not crack when the foundation sinks.
耐老化:管材为黑色抗紫外配方,抗老化性能优异。
Aging resistance: the tube is black and UV resistant, and has excellent anti-aging properties.

重量轻:由于管材结构中空,在保持刚度的前提下,节省原料。同样直径下,单位长度重量是水泥管重量的1/8.施工方便,不需要大型安装设备,减轻了劳动强度,缩短了施工工期。
Light weight: due to the hollow structure of the pipe, raw materials can be saved on the premise of maintaining the stiffness. Under the same diameter, the weight per unit length is 1 / 8 of the weight of the cement pipe. The construction is convenient and does not need large-scale installation equipment, which reduces the labor intensity and shortens the construction period.
排水性能好:管材内壁光滑,流体动摩擦小,流速快。选用中空壁缠绕管,其管道管径可比选用钢筋砼管管径小1-2个管道等级
Good drainage performance: the inner wall of the pipe is smooth, the fluid dynamic friction is small, and the flow velocity is fast. The diameter of hollow wall winding pipe can be 1-2 pipe grades smaller than that of reinforced concrete pipe
经济性能:管材原料价格低,施工、管理、维护费用低。
Economic performance: low price of pipe material, low cost of construction, management and maintenance.
管材连接:通常使用“电热熔带”或“热收缩带”连接技术。管材与管件熔为一体,即保证了连接的强度,又可实现管道系统的零渗漏。本工程中采用了“热收缩带”连接技术。
Pipe connection: usually using "electric melting belt" or "heat shrinkable belt" connection technology. The fusion of pipe and pipe fittings not only ensures the strength of connection, but also realizes zero leakage of pipeline system. In this project, "heat shrinkable belt" connection technology is adopted.
