Date:2020-06-23    Reading count:418

In order to effectively maintain the outer layer of the anti-corrosion spiral steel pipe when exporting, the outer layer of the anti-corrosion spiral steel pipe must be packaged, but there is an irreversible impact on the port of the anti-corrosion spiral steel pipe during the container loading process. At one end of the steel pipe, the friction between the contact point of the forklift and the inner wall of the anticorrosive spiral steel pipe will wear away the anticorrosive layer. This requires that the anticorrosive spiral steel pipe be repaired in time after the box is installed. The following describes the repair steps in detail.


Remove the outer packaging of the anticorrosive spiral steel pipe port, so that the damage of the anticorrosive layer can be seen more clearly. Adjust the original anti-corrosion materials required for anti-corrosion spiral steel pipes (do not add anti-corrosion paint).


Check the anticorrosive spiral steel pipes in order from the bottom of the container, and mark the damaged ones with a marker pen. Use No. 6 roller to stop repairing the marked anticorrosive spiral steel pipe. After repairing, wrap it with outer packing tape and stick it with transparent tape. Nowadays, many customers inquiring for prices directly say that they need to be substandard and cheap. In fact, the difference between the substandard and the national standard is only the difference between the original data and the difference between the original standard and the lower standard.


The detection methods and requests are the same, which has led to many users blindly pursuing low prices, prices are lower, and the difference is larger. The spiral steel pipe market is in disorder, and the quality of the project is getting worse. Many of the sales personnel of manufacturers are currently I don't understand the difference between the Ministry standard and the national standard.
