聚氨酯保溫鋼管廠家：聚氨酯保溫管接口施工標準
Polyurethane Insulation Pipe Manufacturer: Construction Standard for Interface of Polyurethane Insulation Pipe
預(yù)制直埋聚氨酯保溫管接頭的每一個裝置環(huán)節(jié)都能夠影響管網(wǎng)的正常運轉(zhuǎn)。假如接頭進水，水在受熱蒸發(fā)進程中，體積和壓力添加，將招致聚氨酯保溫層遭到毀壞，嚴重的會使聚乙烯外護管開裂，從而使整條管線報廢。上面詳細引見一下聚氨酯保溫管的施工標準。
Prefabricated directly buried polyurethane insulation pipe joints can affect the normal operation of the pipeline network in every device link. If the joint is filled with water and the volume and pressure of water are added in the process of heating and evaporation, the polyurethane insulation layer will be destroyed, and the polyethylene outer guard pipe will be cracked seriously, thus the whole pipeline will be scrapped. The construction standard of polyurethane insulating pipe is introduced in detail above.
1.電熱熔焊結(jié)是經(jīng)過電加熱預(yù)埋在聚乙烯接頭管內(nèi)外表的電熱絲，經(jīng)過電加熱接頭套管和聚乙烯外護管，并施加一定 壓力，使其融爲一體。
1. Electrothermal fusion welding is an electric wire embedded in the inner and outer surface of polyethylene joint pipe by electric heating, through the electric heating joint casing and polyethylene outer protective pipe, and exerting certain pressure to make it into one.
2.液化石油氣火焰加熱熱膨脹帶，經(jīng)過熱膨脹帶膨脹使聚乙烯外護管和接頭套管搭接處密封，完成柔性連 接，既保證了接頭的密封和防水性，又可以吸收管道的軸向位移。采用公用電控制箱對加熱進程停止順序化自動控制，經(jīng)過對不同管徑工藝參數(shù)的控制，取得 佳溶化效果，從而保證接頭的焊接質(zhì)量和密封性，并可傳遞較高的軸向力。
2. Liquefied petroleum gas flame heating thermal expansion belt, after thermal expansion belt expansion, the polyethylene outer guard pipe and joint sleeve lap seals, completes the flexible connection, not only guarantees the joint seals and waterproof, but also can absorb the axial displacement of the pipeline. The public control box is used to stop the sequential automatic control of heating process, and the optimum melting effect is obtained by controlling the technological parameters of different pipe diameters, so as to ensure the welding quality and sealability of joints, and to transmit higher axial force.
聚氨酯保溫管在施工中要具有高素質(zhì)的裝置隊伍和的發(fā)泡技術(shù)團隊，嚴厲依照施工標準操作，防止了手工發(fā)泡計量不準、攪拌不勻以及注料不及時等弊端。聚氣醋發(fā)泡采用現(xiàn)場公用發(fā)泡機停止，高精度的比例及溫度自動化控制保證 現(xiàn)場發(fā)泡質(zhì)量同等于工廠預(yù)制保溫管材的發(fā)泡質(zhì)量。
Polyurethane insulation pipes should be constructed with high-quality professional installation team and advanced foaming technology team, strictly in accordance with the construction standards, to prevent manual foaming measurement inaccurate, uneven mixing and improper feeding and other shortcomings. Foaming of polyvinegar is stopped by public foaming machine on site. High precision proportion and automatic temperature control ensure that the quality of foaming on site is equal to the quality of foaming of factory prefabricated insulation pipes.
In summary, all the above-mentioned Shandong Hipper Pipe Technology Development Co., Ltd. provides, want to know more about polyurethane insulation pipe manufacturers, welcome to pay attention to our website: http://www.qndr49.cn Thank you for your support!
