1. Regular inspection: Regularly inspect the lined polyurethane steel pipe, including appearance, insulation layer, pipe support and connection parts. Detect and repair damage and problems in time to avoid greater losses as problems aggravate.
2. Keep it dry: The polyurethane steel pipe lined with polyurethane should be kept dry in the pipe to avoid water accumulation and humidity in the pipeline. This prevents corrosion and damage to the pipes, resulting in a longer service life.
3. Anti-impact and damage: avoid impact and damage to the lined polyurethane steel pipe, and prevent cracks and dents in the pipeline. These problems can affect the insulation and service life of the pipes.
4. Prevent chemical erosion: Directly buried insulation steel pipes for heating should be protected from the erosion of chemical substances, such as acid and alkali. If the steel pipe comes into contact with these substances, it should be cleaned and repaired in time.
5. Maintenance: Regularly maintain the lined polyurethane steel pipe, such as cleaning, coating anticorrosive paint, and replacing insulation materials. The maintenance work should be carried out according to the actual situation to ensure the normal operation and service life of the pipeline.
6. Bracket inspection: regularly check the status of the pipeline support, and strengthen it in time if it is loose to ensure the stability of the pipeline. The loosening of the bracket will lead to the displacement and deformation of the pipe, affecting the insulation effect and service life.
7. Safe operation: When maintaining and overhauling the polyurethane steel pipe, the safety operation procedures should be followed to ensure the safety of the staff. Especially when carrying out dangerous work such as welding and grinding, it is necessary to take necessary safety measures.
The installation of polyurethane steel pipes needs to follow several codes and standards to ensure the quality of installation and the effectiveness of use. Here are some of the norms and standards to follow:
1. Code for Construction and Acceptance of Directly Buried Heating Pipelines (GB50264-2016): This standard stipulates the construction technology, quality standards and acceptance requirements of directly buried heating pipelines, and is one of the basic specifications for installation projects.
2. "Prefabricated Directly Buried Insulation Steel Pipe for Urban Heating" (CJ T114-2000): This standard stipulates the product classification, technical requirements, test methods, inspection rules and packaging, transportation, storage and other requirements of prefabricated directly buried insulation steel pipes for urban heating, and is one of the standards to be followed in installation projects.
3. Code for Construction and Acceptance of Anti-corrosion Engineering of Steel Pipelines and Storage Tanks (SY T0407-96): This standard stipulates the construction technology, quality standards and acceptance requirements of anti-corrosion engineering of steel pipelines and storage tanks, and is one of the standards to be followed in the installation project.
4. Code for Quality Acceptance of Building Water Supply, Drainage and Heating Engineering Construction (GB50242-2002): This standard stipulates the quality acceptance standards and requirements for the construction of building water supply, drainage and heating engineering, and is one of the standards to be followed in the installation project.
5. Code for Fire Protection Design of Buildings (GB50016-2014): This standard stipulates the fire protection requirements and measures in building design, and is one of the standards to be followed in installation projects.
