The quality of non-standard straight seam welded steel pipes not only affects their service life but also their efficiency. So, how can we ensure we purchase high-quality non-standard straight seam welded steel pipes?
First, we can judge the quality of non-standard straight seam welded steel pipes by their appearance. If the surface is rough and uneven, the pipe is of poor quality. Also, carefully observe the surface for scratches or cracks; if these are present, the pipe is definitely a substandard product. Furthermore, substandard steel pipes lack metallic luster and are often pale red or similar to cast iron in color. Secondly, we can examine the cross-section of the pipe. An uneven cross-section indicates a substandard product.
