What items are checked in spiral steel pipes before factory shipment

The production of spiral steel pipes is subject to many constraints. If the current is slightly too high, weld penetration can occur; if it's slightly too low, insufficient welding may result. Additionally, due to their thin wall thickness, http://www.hnftsteels.com,spiral steel pipes require careful attention during procurement.

1.Check whether the spiral steel pipe has any misalignment in its appearance.

2.Inspect the welds for leaks or porosity (pinholes).

3.Verify whether support brackets are installed inside the pipe ends.

4.Ensure the external coating/spraying is properly applied.

5.During transportation, no additional cargo should be stacked on top of the spiral steel pipes.

6.If the pipe diameter is relatively small and requires sleeving, only the bottom layer should be sleeved.
