China Spirally Steel Pipes Suppliers, Manufacturers, Factory

Product Details

spirally steel pipes Even the materials provided by the same manufacturer may have quality problems due to different batches.The problem is that in the acceptance of welding materials generally, the acceptance method agreed by the customer and the welding material manufacturer is in accordance with the welding material production standard test and acceptance.

Even the materials provided by the same manufacturer may have quality problems due to different batches.The problem is that in the acceptance of welding materials generally, the acceptance method agreed by the customer and the welding material manufacturer is in accordance with the welding material production standard test and acceptance, especially the welding process performance does not have a suitable method for pipeline welding evaluation, so the acceptance of welding materials does not necessarily mean that the pipeline can be welded.

In order to control the quality, welding materials consistent with the project should be used as far as possible.Welding materials should be selected from mature manufacturers as far as possible. For welding materials of different batches, the acceptance method for welding process performance of pipelines should be formulated.
