Polyurethane Insulation Pipe Manufacturer: Construction Standard for Interface of Polyurethane Insulation Pipe

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. 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. 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.

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.
