Polyurethane insulation pipe is a common insulation material in modern insulation engineering, and its direct buried polyurethane foam insulation pipe with a diameter of 114mm has a wide range of applications in thermal insulation engineering. This article will introduce the performance characteristics, production process, application fields and construction and installation of polyurethane insulation pipe, so that readers can better understand the advantages and applications of the insulation pipe. Polyurethane insulated steel pipe Polyurethane insulated steel pipe 1. Performance characteristics The direct buried polyurethane foam insulation pipe with a diameter of 114mm has excellent thermal insulation performance, low thermal conductivity and thick thermal insulation layer, so it can effectively reduce heat loss and improve thermal insulation efficiency. In addition, the insulation pipe also has high mechanical strength and impact resistance, can withstand large pressure and impact force, and is not easy to damage. At the same time, the insulation pipe also has good corrosion resistance and waterproof performance, and can adapt to various harsh environmental conditions.
Second, the production process.
The production process of 114mm diameter directly buried polyurethane foam insulation pipe mainly includes the following steps:
1.Steel pipe selection: Select high-quality steel pipes that meet the requirements as the external structure of the insulation pipe.
2.Steel pipe pretreatment: pretreatment such as rust removal and cleaning is carried out on the steel pipe to ensure the cleanliness and flatness of the steel pipe surface.
3.Polyurethane foaming: After mixing the polyurethane raw materials according to a certain proportion, it is injected into the inside of the steel pipe, and a uniform foam layer is formed through the action of the foaming agent.
4.Curing treatment: After a certain period of curing treatment, the foam layer is tightly combined with the steel pipe.
5.Testing and packaging: The cured insulation pipe is tested, and packaged after it is qualified.
Third, the field of application.
The 114mm diameter of directly buried polyurethane foam insulation pipe is widely used in various pipeline insulation projects, such as petroleum, chemical industry, electric power, heating and other fields. In the process of pipeline transportation, the insulation pipe can effectively reduce heat loss, improve transportation efficiency, and at the same time can protect the pipeline from the external environment and prolong the service life of the pipeline.
Fourth, construction and installation.
The construction and installation of 114mm diameter directly buried polyurethane foam insulation pipe mainly includes the following steps:
1.Trench excavation: According to the design requirements, excavate the trench that meets the requirements.
2.Pipe installation: Install the polyurethane insulation pipe into the trench according to the design requirements.
3.Backfill: After the installation of the pipeline is completed, the backfill work is carried out, and the backfill should be compacted in layers to ensure the safety of the pipeline.
4.Waterproof layer construction: After the backfill is completed, the waterproof layer construction is carried out to prevent water from seeping into the insulation layer.
5.Acceptance and testing: Acceptance and testing of the installed insulation pipe to ensure that it meets the design requirements and is safe to use.
In a word, the 114mm diameter directly buried polyurethane foam insulation pipe is a kind of insulation material with excellent performance, and has a wide range of application prospects in various pipeline insulation projects. During the construction process, the relevant specifications and requirements should be strictly adhered to to ensure the construction quality and safety of use.
