Spiral Welded Steel Pipes

We design and manufacture the pipes specially for any project in terms of diameter, length, wall thickness, steel quality, coating, pipe ends etc.The spiral welded steel pipe, is a steel pipe with the lenght wise seamed in the shape of spiral. Inside and outside, welding is performed by a process called automatic submergeeed arc. The usage fields of Spiral Welded Steel Pipes are pilling, irrigation, boring equipping, water transmission, steel structures, canalization and distribution of drinkable water.
