High-frequency resistance welded steel pipe
Share to：
ERW refers to Electric Resistance Welded pipe, a manufacturing method that melts and welds the edges of a circular ERW steel pipe or resistance welded steel pipe into a uniform cylindrical shape. Heat and pressure are combined to join the steel sheets, providing you with lightweight and easy-to-use pipes to meet a range of engineering and construction requirements. It is widely used in commercial settings with multiple possibilities.
Including: load-bearing piles, driven piles, driven piles, composite walls, structural sections, threaded micropile casings, marker posts, towers and transmission lines, mining, underground garages, bridge abutments and embankments, storm protection, horizontal pipelines, geotechnical solutions, solar energy solutions.
