(总结描述)热熔和电熔是焊接塑料管的常用方法。一种用热熔机对待焊接的两根PE管进行加热、铣削和加热,将PE管的端口熔化,用专用工具压紧,将两根PE管连接起来的方法。大口径pe管适用于这种热熔方式。电熔采用专用熔合管套,PE管件为专用热熔管件。管件上设有电热丝与外柱连接。电加热融化后,连接完成。施工方便,稳定性好,人工成本低。价格高,适用于小直径管道。PE给水管道的翻边是在管道焊接过程中通过挤压成形的。它通常被称为翻边和翻边。 The quality of the flanging also affects the flow efficiency of the PE pipe. Excessive flanging is also prone to scaling , Resulting in the breeding of microorganisms in the pipeline, silting in the drainage project, and reducing the efficiency of water flow. The reason for the inconsistent height of the pe water supply pipe flanges is that the water supply pipe is not level, uneven, and the heating area is uneven, which must be remelted. In the previous PE water supply pipeline construction, there is no good method to deal with internal flanging. Hengxing Management Industry summarized some of the reasons for the unqualified flanging of PE water pipes: Hot melt connection standard specification The connection of pe pipes and fittings should adopt hot-melt connection (hot-melt butt, hot-melt socket connection, hot-melt saddle connection) or electro-fusion connection (electro-fusion socket connection, electro-fusion saddle connection) and mechanical connection (lock Tight and non-locking socket connection, flange connection, steel-plastic over-connection). Pipes with a nominal outer diameter greater than or equal to 63mm should not be connected by manual hot-melt sockets, pipes with a wall thickness of less than 6mm should not be connected by hot-melt butt joints, and polyethylene pipes and fittings should not be connected and bonded by thread. Corresponding special connection tools should be used for various connections of pipelines. Open flame heating is strictly prohibited when connecting. The connection of pe pipes should be of the same grade, pipes and fittings of the same pressure grade, and the connections between pipes and fittings of different grades should be tested to determine whether they can be connected. When performing hot-melting or electro-melting connection operations in cold climates (below -5°C) or high wind conditions, protective measures should be taken, or the process parameters of the connection equipment should be adjusted. When connecting pipes, special cutters or pipe cutting tools should be used for pipe cutting. The cutting section should be flat, smooth, and free of burrs, and should be perpendicular to the pipe axis. Polyethylene (PE) water supply pipelines should be connected with pipes and pipes of the same manufacturer, material, and brand, and between pipes and fittings, and between pipes and pipes. Polyethylene pipes of different SDR series should not be welded. For connection, when pipes and fittings of different SDR series are welded to each other, it is advisable to make the welded joint wall thickness the same through mechanical processing. After heating, quickly remove the heating tool and check for damage.

PE管翻边观察热熔连接标准规范

(总结描述)热熔和电熔是焊接塑料管的常用方法。一种用热熔机对待焊接的两根PE管进行加热、铣削和加热,将PE管的端口熔化,用专用工具压紧,将两根PE管连接起来的方法。大口径pe管适用于这种热熔方式。电熔采用专用熔合管套,PE管件为专用热熔管件。管件上设有电热丝与外柱连接。电加热融化后,连接完成。施工方便,稳定性好,人工成本低。价格高,适用于小直径管道。

PE给水管道的翻边是在管道焊接过程中通过挤压成形的。它通常被称为翻边和翻边。翻边的质量也影响着PE管的流动效率。过度的燃料也容易缩放,导致管道中微生物的繁殖,淤塞在排水项目中,降低水流的效率。

pe供水管法兰高度不一致的原因是供水管不平整,不均匀,加热面积不均匀,必须重熔。在以前的PE供水管道施工中,没有很好的方法处理内翻边。恒兴管理业总结了PE水管翻边不合格的一些原因:

热熔连接标准规范

pe管、管件的连接应采用热熔连接(热熔对接、热熔承插连接、热熔鞍座连接)或电熔连接(电熔承插连接、电熔鞍座连接)和机械连接(锁紧、非锁紧承插连接、法兰连接、钢塑over-connection)。公称外径大于或等于63mm的管道不宜采用人工热熔接套连接,壁厚小于6mm的管道不宜采用热熔对接连接,聚乙烯管材及管件不宜采用螺纹连接粘接。管道的各种连接应使用相应的专用连接工具。连接时严禁明火加热。pe管的连接应同等级,同压力等级的管和管件,不同等级的管和管件之间的连接应进行试验,以确定是否可以连接。在寒冷气候(-5℃以下)或大风条件下进行热熔或电熔连接操作时,应采取防护措施,或调整连接设备的工艺参数。连接管道时,应使用专用刀具或管切割工具进行管切割。切割断面应平整、光滑、无毛刺,且应垂直于管道轴线。聚乙烯(PE)供水管道应与同一厂家、同一材质、同一品牌的管道、管道与管件之间、管道与管道之间进行连接。 Polyethylene pipes of different SDR series should not be welded.
