Third, the construction process.
1.Preparation: Before construction, the quality inspection of DN1020*12 plastic-coated spiral steel pipe should be carried out to ensure that the pipe is defect-free and the coating is complete. At the same time, the required connecting materials and tools should be prepared.
2.Cutting: The DN1020*12 plastic-coated spiral steel pipe is cut according to the required length by a cutting machine, and the cutting section should be flat and stabbed.
3.Connection: Flange, welding and other methods can be used to connect the plastic-coated spiral steel pipe to ensure firm connection and good sealing.
4.Installation: According to the requirements of the construction drawings, install the DN1020*12 plastic-coated spiral steel pipe to the specified position, and pay attention to keeping the pipeline route straight and firm.
5.Acceptance: After the construction is completed, the quality acceptance of the DN1020*12 plastic-coated spiral steel pipe should be carried out to ensure that the installation quality of the pipeline meets the design requirements.
4. Precautions.
1.During transportation and construction, it should be avoided to cause violent impact and friction on the DN1020*12 plastic-coated spiral steel pipe, so as not to damage the coating and pipe body.
2.During installation, the pipeline route should be kept dry and ventilated to avoid moisture and pollution.
3.When carrying out the connection operation, the appropriate connection method and technology should be selected to ensure that the connection is firm and sealed.
4.During acceptance, attention should be paid to the firmness, tightness and anti-corrosion performance of the pipeline installation to ensure that the quality of the pipeline meets the requirements.
To sum up, DN1020*12 plastic-coated spiral steel pipe, as a new type of steel pipe material, has excellent anti-corrosion performance and hygienic performance, and is widely used in various fields. Its construction technology is simple and convenient, with high cost performance and reliability, and is one of the important development directions of pipeline transportation in the future.
