To solve the problem of excessive misalignment in the alignment of spiral steel pipe nozzles, the following preventive measures should be taken in quality management control:
1. Try to use the internal alignment device.
2. Do a good job of engineering measurement and trimming during assembly.
3. When aligning the welded pipe group, do a good job of grading the cross-section of the welded pipe.
4. Copper hammers or copper plate hammers can be used locally for analysis and correction.
5. When there is misalignment and deformation, the gap should be processed.
Safety management of spiral steel pipes:
1. Before assembly, carefully check whether the relevant equipment can operate normally. During assembly, designate a special person to direct and operate by relevant standards to avoid injuries.
2. During construction, if it is necessary to pre-lay the relevant pipelines with stone piers or sacks, the cushion design must have a solid foundation to prevent accidents of pipeline rolling and injuring people; it is strictly forbidden to use frozen soil and stones as cushions for spiral steel pipes.
The correct use of spiral steel pipes directly affects the service life of steel pipes, so when assembling spiral steel pipes, it must comply with relevant specifications to avoid serious impact on subsequent use.
