聚氨酯保温钢管厂家：聚氨酯保温管接口施工标准
Polyurethane Insulation Pipe Manufacturer: Construction Standard for Interface of Polyurethane Insulation Pipe
预制直埋聚氨酯保温管接头的每一个装置环节都能够影响管网的正常运转。假如接头进水，水在受热蒸发进程中，体积和压力添加，将招致聚氨酯保温层遭到毁坏，严重的会使聚乙烯外护管开裂，从而使整条管线报废。上面详细引见一下聚氨酯保温管的施工标准。
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.电热熔焊结是经过电加热预埋在聚乙烯接头管内外表的电热丝，经过电加热接头套管和聚乙烯外护管，并施加一定 压力，使其融爲一体。
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.液化石油气火焰加热热膨胀带，经过热膨胀带膨胀使聚乙烯外护管和接头套管搭接处密封，完成柔性连 接，既保证了接头的密封和防水性，又可以吸收管道的轴向位移。采用公用电控制箱对加热进程停止顺序化自动控制，经过对不同管径工艺参数的控制，取得 佳溶化效果，从而保证接头的焊接质量和密封性，并可传递较高的轴向力。
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.
聚氨酯保温管在施工中要具有高素质的装置队伍和的发泡技术团队，严厉依照施工标准操作，防止了手工发泡计量不准、搅拌不匀以及注料不及时等弊端。聚氣醋发泡采用现场公用发泡机停止，高精度的比例及温度自动化控制保证 现场发泡质量同等于工厂预制保温管材的发泡质量。
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.
