1. Material selection criteria.
The pipes are required to be made of high-quality steel, and their physical, chemical and mechanical properties are strictly tested, and comply with the corresponding national standards and regulations.
2. Selection criteria for anticorrosive coatings.
It is required that the selected epoxy coal asphalt anticorrosive coating meets the relevant national standards and can meet the requirements of different occasions.
3. Pipeline manufacturing standards.
Manufacturers are required to adopt modern production processes and equipment in accordance with the requirements of the specifications to ensure that the size, shape, bending and wall thickness of the pipeline meet the requirements.
4. Pipeline connection standards.
It is required that the connection method adopts east-west bending, port, socket, etc., and operates in strict accordance with the standard requirements to ensure that the connection is firm and sealed.
5. Construction technology standards.
The construction party is required to operate in strict accordance with the design plan, strictly control the construction quality, and ensure the safety and reliability of the pipeline.
During the construction process, the following aspects should be paid attention to:
1. Ensure that the coating quality and thickness of epoxy coal asphalt anticorrosive longitudinal steel pipe are uniform.
2. Clean up impurities and corrosives on the surface of the pipeline to ensure that the surface of the pipeline is smooth and clean.
3. Ensure that the starting bend, final bend and bending radius of the pipeline meet the design requirements.
4. Strictly control the pressure test to ensure the safety performance of the pipeline.
