观察PE管翻边热熔连接标准规范

观察PE管翻边热熔连接标准规范

热熔和电熔是塑料管道焊接的常用方法。一种将两根要用热熔机焊接的PE管加热、铣削、加热,熔化PE管的端口,用专用工具压制,连接两根PE管的方法。大口径钢管适用于这种热熔方式。电熔合采用专用熔合管套,PE管件为专用热熔管件。管件配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供水管在焊接过程中通过挤压形成翻边。它通常被称为倒置和翻边。 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.
