How to manage the safety of spiral welded steel pipes

To address the issue of excessive misalignment during nozzle alignment in spiral welded steel pipes, the following preventative measures should be taken in quality management control:

1. Use internal alignment devices whenever possible.

2. Conduct thorough engineering measurements and trimming during assembly.

3. When aligning welded steel pipe assemblies, perform grading of the welded steel pipe cross-section.

4. Localized corrections can be performed using a copper hammer or copper plate hammer.

5. For misalignment and deformation, the notches should be machined.

Safety management of spiral welded steel pipes:

1. Before assembly, carefully check whether the relevant equipment is functioning properly. During assembly, assign a dedicated person to direct the operation, following relevant standards to avoid accidents.

2. During construction, if it is necessary to pre-lay stone blocks or burlap sacks on the relevant pipelines, the bedding design must be based on a solid foundation to prevent accidents caused by pipe rolling and injury; frozen soil and gravel are strictly prohibited as bedding for spiral welded steel pipes.

The correct use of spiral welded steel pipes directly affects their service life. Therefore, when assembling spiral welded steel pipes, it is essential to comply with relevant specifications to avoid serious impacts on subsequent use.
