PE管法兰观察热熔连接标准规格

热熔和电熔是焊接塑料管的常用方法。一种加热,铣削和加热两个PE管通过热熔机焊接的方法,熔化PE管道的端口,用特殊工具压制,并连接两个PE管道。大口径PE管适用于这种热熔的方式。电气融合采用特殊熔管套管,PE管配件是特殊的热熔管配件。管接头配有电加热电线,以连接到外柱。电加热熔化后,连接完成。施工方便,稳定性好,劳动力成本低。价格高,适用于小直径管道。PE水供应管的燃料通过管焊过程中的挤出形成。它通常被称为反转和燃料。 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.
