1. Material Selection: The quality of the pipe starts with the selection of the raw material. High-quality steel grades that meet the required specifications for strength, durability, and corrosion resistance should be chosen.2. Welding Process Control: High frequency welding machines should be cali

1. High productivity: High frequency welding can achieve high welding speed, which reduces production time and improves productivity.2. High quality welds: High frequency welding creates strong and reliable welds with minimal porosity and voids, resulting in superior quality and durability.3. Simple

1. Inferior thick-walled seamless steel pipe prone to folding. Folding is thick-walled seamless steel pipe surface formed by a variety of polyline, this defect is often throughout the product's vertical. The cause of folding is due to the pursuit of high efficiency shoddy manufacturers, the amount o

As the individual quality of spiral steel pipe is relatively large, it must be stacked in the outdoors, but it will be difficult to avoid the sun and rain, so the problem has been plagued with rust spiral pipe storage time and conditions. Therefore, we need to conduct a comprehensive understanding o
