1. Characteristics of polyurethane direct buried insulation spiral steel pipe.
Polyurethane direct buried insulation spiral steel pipe is a new type of pipe with excellent thermal insulation performance, and its main features are as follows:
1.Strong anti-corrosion performance: polyurethane rigid foam has good corrosion resistance, which can effectively prevent external corrosion and chemical corrosion.
2.Good thermal insulation performance: polyurethane rigid foam has low thermal conductivity, remarkable thermal insulation effect, and can effectively reduce energy consumption.
3.High strength: Polyurethane rigid foam has high compressive strength and impact strength, and can withstand large internal and external pressure differences.
4.Good sealing: Polyurethane rigid foam has a good closed-cell structure, which can effectively prevent water vapor penetration.
5.Easy installation: The polyurethane direct-buried insulation spiral steel pipe adopts the prefabricated direct burial method, which can be quickly installed and disassembled.
2. Rapid installation and disassembly of polyurethane directly buried insulation spiral steel pipe.
1.Support fast installation: Polyurethane direct buried insulation spiral steel pipe adopts prefabricated direct burial method, which can achieve rapid installation. At the construction site, the installation can be completed by simply connecting the prefabricated insulation pipes. This method not only improves the construction efficiency, but also reduces the difficulty of on-site construction.
2.Support quick disassembly: Because the polyurethane direct buried insulation spiral steel pipe has good detachability, it can be quickly disassembled and reinstalled when it needs to be repaired or replaced. This saves time and reduces maintenance costs.
3.Guarantee the quality of construction: The premise of quick installation and disassembly is to ensure the quality of construction. Therefore, during the construction process, the operation should be carried out in strict accordance with the design requirements and construction specifications to ensure the quality and performance of the pipeline.
