CS Seamless Pipes Exporters & Stockists In India

CS seamless pipes are manufactured without a welded seam, ensuring the integrity and strength of the product. These Seamless pipes are made from solid steel billets that are heated and then stretched over a form until the steel takes the shape of a hollow tube. The seamless nature of these carbon steel pipes means they can withstand higher pressure, making them ideal for critical applications. Hence many industries prefer seamless carbon steel pipe for high temperature service as well as low temperatures .
