Oil & gas steel pipe production line, categorized by pipe diameter (medium/large) and process type (ERW), specializes in manufacturing pipelines for oil & gas transmission. Features: high precision (medium-diameter), strong pressure resistance (large-diameter), and corrosion-resistant processing. Advantages: stable continuous production, superior weld integrity, high automation, and long service life of products. Key parameters: pipe diameter/wall thickness range, production speed, welding power, and pressure test standard, ensuring pipeline safety and reliability. Widely applied in oilfield development and long-distance transmission projects.
