Seamless Pipes
Seamless Pipes
Seamless pipes are manufactured without a welded seam, making them stronger and more reliable for high-pressure applications. These pipes are produced through a hot rolling or cold drawing process, ensuring uniformity in shape and dimensions. They are widely used in industries such as oil & gas, petrochemicals, power plants, and marine applications due to their superior strength, corrosion resistance, and ability to withstand extreme conditions.
