As one of the leading alloy steel seamless pipe manufacturers in India, we produce pipes with an optimized chemical composition that enhances heat resistance, oxidation protection, and mechanical strength. Depending on the grade, these pipes are composed of silicon (Si) 0.50–1.00%, molybdenum (Mo) 0.44–1.05%, chromium (Cr) 1.00–9.50%, manganese (Mn) 0.30–0.80%, and carbon (C) 0.05–0.15%. This combination enhances thermal stability and corrosion resistance in boilers, steam pipes, and heat exchangers. The alloy steel seamless pipes remove weak weld seams; they extend service life and need less maintenance, which is particularly advantageous for high-pressure systems.
We manufacture Alloy Steel High-Pressure Pipes in various sizes, specifications, and thicknesses to meet different industrial needs. These pipes are available in custom-cut diameters according to project specifications, as well as single random lengths (4–7 meters) and double random lengths (7–13 meters). They provide the ideal mix of strength and flexibility, with wall thicknesses ranging from 1 to 20 mm and exterior diameters between 6 and 610 mm. Our seamless pipes, which come in ASTM A335 grades P1, P5, P9, P11, P22, and P91, are made to satisfy the exacting requirements of chemical processing plants, thermal power plants, and the oil and gas industry.
As a reputed alloy steel pipe distributor, we offer both seamless and welded pipes, available in different surface finishes, including bare, black, galvanized, and epoxy-coated options. Hydrostatic, ultrasonic, and PMI (Positive Material Identification) tests are used on each pipe to make sure it meets the standards set by ASTM A335, ASME SA335, DIN 17175, and EN 10216-2. These rigorous tests guarantee high performance, safety, and long-term durability, making our pipes a preferred choice for critical applications.
Our specialty at Piyush Steel is offering premium pipes made of alloy steel at affordable costs, supported by prompt and dependable international delivery. We provide specialized solutions that meet industry requirements, whether you require Chrome Moly Pipes, ASTM A335 Seamless Pipes, or Alloy Steel High-Pressure Pipes. Please feel free to reach out to us to find the ideal alloy steel pipes for your project.
