A batch of extra-large and extra-long submerged arc spiral welded steel pipes with a diameter of 2032 mm and a length of 18 meters have been loaded onto vessels at Yangzhou Port and shipped to Saudi Arabia. The pipes will be used for local seawater desalination projects and urban water transmission pipeline construction.
The steel pipes adopt high-precision submerged arc spiral welding technology, featuring high weld strength and stable quality. The rolling precision is controlled at the 0.01-millimeter level throughout the production process. All products have passed multiple strict inspections, including hydrostatic pressure testing, X-ray flaw detection and ultrasonic flaw detection.
Comprehensive protection measures are adopted during transportation, such as soft cushioning and professional palletizing, to ensure the pipes remain intact in appearance.
