Grades & Standards:

We produce alloy steel pipes that meet the most stringent international specifications, including:

· ASTM A335 (Chrome-Molybdenum): Common grades P5, P9, P11, P22, P91. Ideal for high-temperature piping applications.

· ASTM A213: Grades T5, T9, T11, T22, T91. Designed for boiler tubes, superheaters, and heat exchangers.

· ASTM A519: Covers a wide range of carbon and alloy steel mechanical tubing.

These grades are enriched with elements like Chromium (Cr), Molybdenum (Mo), and Nickel (Ni) to enhance their mechanical properties.

Primary Applications:

Our alloy steel seamless pipes are critical components in demanding industries worldwide:

· Power Generation: Fossil fuel power plants, nuclear facilities, and thermal stations for boiler tubes, steam lines, and high-temperature headers.

· Oil & Gas: Refineries and petrochemical plants for process piping, heater tubes, and fittings exposed to high pressure and corrosive media.

· Chemical Processing: For equipment requiring resistance to oxidation and corrosion from aggressive chemicals.

· High-Temperature Service: Any application involving elevated temperatures and pressures that demand exceptional creep strength.
