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

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. 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. Inspection: Regular visual inspections of the tube's sidewalls can help identify any signs of damage, corrosion, or defects. This can help in detecting issues early and taking corrective actions promptly.2. Proper Handling: Careful handling of the steel tubes during transportation, storage, and i

The main purpose of pickling cold-rolled steel plates is to remove oxide scale and rust on the surface to improve the surface finish and corrosion resistance of the steel plates. The pickling process usually uses dilute sulfuric acid or hydrochloric acid to corrode oxides and impurities on the surfa
