高密度聚乙烯缠绕结构壁管材的结构特点有哪些?

高密度聚乙烯(HDPE)缠绕结构壁管材(B型),俗称克拉管,我们一起来看一下它在结构的上个特点:
High density polyethylene (HDPE) winding structural wall pipe (type b), commonly known as Clarke tube, let's take a look at its structural features
1、管材直径
1. Pipe diameter
克拉管的直径可以从300mm到4000mm,两相邻规格的管材直径可相差100mm. 克拉管的公称直径为管材的内径,因此在管材的环刚度或者壁厚变化时,管材的内径不变,从而保证水流量不受影响。
The diameter of Clarke tube can be from 300 mm to 4000 mm, and the diameter difference between two adjacent specifications can be 100 mm.
2、管材结构
2. Pipe structure
克拉管的公称长度一般为6米,克拉管管身分为三部分,部分为承口,第二部分为管材主体,第三部分为插口。这三部分都是在线一次性成型。每一部分的厚度都可以根据工程需求灵活生产,因而管材的整体强度非常高。
The nominal length of the Clarke tube is generally 6 meters. The Clarke tube consists of three parts, some of which are bell mouth, the second part is the main body of the pipe, and the third part is the socket. These three parts are all online one-time molding. The thickness of each part can be flexibly produced according to the engineering requirements, so the overall strength of the pipe is very high.
克拉管的承口处为锥形内径,插口处为锥形外径,这种结构可以保证在采用电熔连接时,两根管子将会被牢牢的焊接在一起而没有任何的缝隙。

The bell mouth of the Clarke tube is a conical inner diameter, and the socket is a conical outer diameter. This structure can ensure that the two tubes will be firmly welded together without any gap when using electric fusion connection.
3、管壁结构
3. Pipe wall structure
克拉管的水接触层的厚度可从2mm做到300mm,因而克拉管可以做为排污排水或者供水管。考虑到管材的可靠性及施工,建议水平层的壁厚小为4mm.
The thickness of the water contact layer of the Clarke tube can be changed from 2 mm to 300 mm, so it can be used as sewage drainage or water supply pipe. Considering the reliability and construction of pipe, it is suggested that the wall thickness of horizontal layer should be less than 4mm
克拉管的承重层可根据工程要求采用多种管壁结构来增强环刚度。这些管壁结构在增加环刚度的同时减轻了管材的重量,节省了材料。管材的环刚可以从2KN/M2到32KN/M2。
According to the engineering requirements, the bearing layer of the Clarke tube can adopt a variety of pipe wall structures to enhance the ring stiffness. These pipe wall structures not only increase the ring stiffness, but also reduce the weight of the pipe and save materials. The ring stiffness of the pipe can be from 2Kn / m2 to 32KN / m2.
