Alloy steel Seamless Pipes Exporters & Stockists In India
Seamless alloy steel pipes are composed of steel combined with other elements including molybdenum, nickel, and chromium. The pipe is extruded during the seamless production process, producing a product with no welded connections that increases strength and longevity. Oil and gas, power generation, petrochemicals, and other industries depend heavily on seamless alloy pipes. The world market for these premium pipes is served by a sizeable number of exporters and stockists in India. This article explores the salient features, advantages, and leading Indian exporters and stockists of alloy steel pipes.
Major Grades and Specification for Seamless Alloy Steel Pipes
ASTM A335 Alloy Seamless Steel Pipes
ASTM A335, also known as ASME SA335, is a seamless ferritic alloy-steel pipe specifically designed for high-temperature service. The various grades offer a combination of high strength, resistance to scaling, and ability to handle high pressures, making them suitable for:
- Power Plants: Ideal for boiler systems, superheater elements, and steam lines due to their high-temperature strength.
- Petrochemical Industry: Used in refineries and chemical plants where high pressure and temperature resistance are critical.
- Oil and Gas: Suitable for use in high-pressure environments such as in oil drilling and gas processing.
ASTM A335 Grades
- Gr. P5: Offers excellent resistance to oxidation and scaling at high temperatures. Used in petroleum refineries.
- Gr. P9: Known for its high chromium content, providing superior oxidation and corrosion resistance.
- Gr. P11: Combines good high-temperature strength with corrosion resistance, widely used in power plants.
- Gr. P12: Similar to P11 but with different chemical composition, making it suitable for specific high-temperature applications.
- Gr. P21 & P22: Commonly used in the power industry for components that must withstand high temperature and pressure.
- Gr. P91: Offers exceptional high-temperature strength and creep resistance, widely used in advanced power plants and refineries.
ASTM A213 Alloy Steel Seamless
Tubes
ASTM A213 (ASME SA213) specification covers seamless ferritic and austenitic alloy steel boiler, superheater, and heat-exchanger tubes. These tubes are designed for high-temperature services and exhibit excellent heat and corrosion resistance.
ASTM A213 Grades
- T5: Suitable for high-temperature services with good heat and corrosion resistance.
- T9: Offers excellent high-temperature oxidation resistance and is often used in superheaters.
- T11: Known for its strength and resistance to heat and corrosion, commonly used in boiler applications.
- T12: Similar to T11 but with different chemical composition, suitable for heat exchangers and boiler components.
- T22: Offers high strength and resistance to scaling at elevated temperatures, used in pressure vessels and heat exchangers.
- T91: Known for its superior high-temperature strength and creep resistance, making it ideal for power plants and high-pressure applications.
ASTM A691 Alloy Seamless Steel Pipes
ASTM A691 specification covers carbon and alloy steel pipes that are electric-fusion welded with added filler metal. These pipes are intended for high-pressure service at moderate temperatures.
