Penstock pipes are thick steel pipes used to carry high-pressure water to turbines in hydro power plants. They’re built strong to handle the force of moving water.These pipes are mostly made from mild steel or carbon steel, known for their strength, durability, and resistance to pressure. Champak Steel & Engg. Co manufactures penstock steel pipes with good mechanical strength, ductility and long service life. The surface can be plain or coated for extra protection against wear and corrosion.
An essential part of hydroelectric power systems are steel penstocks. They transfer water from the dam to turbines, helping generate power. Water is directed from a dam or reservoir to the turbine by a hydroelectric penstock pipe. As water flows through the pipe, pressure builds, and drives the turbine, helping produce clean energy. Penstocks in Pelton turbines are used in both small and large hydro plants. These pipes are also seen in irrigation, mining, and dam penstock systems. It has a high tensile strength, smooth flow design, low maintenance, and long-term performance under pressure. They handle water hammer, and tough site conditions with ease.
Depending on the requirements of the project, we provide penstock pipes in a range of sizes and wall thicknesses. Sizes vary from 600 mm to 3000 mm and even more in some cases. Both seamless and welded variants are available. Most pipes are supplied in straight lengths, often with flanges or welding ends. The price depends on size, thickness, and coating. We offer both standard and custom-built pipes to match exact specs.
All penstock pipes are tested for strength, leak-proof design, and corrosion resistance. We follow strict quality standards like IS: 3589, IS: 2062, and API 5L. Every pipe goes through hydro testing and visual checks before dispatch. For dependable and durable penstock pipes, connect with our team for expert guidance and customized solutions.
