Applications of Alloy Steel Pipes and Tubes

Alloy Steel Pipes and Tubes are engineered for performance under pressure, making them indispensable in industries where extreme temperature, corrosion resistance, and mechanical strength are non-negotiable. Here’s where our alloy steel products are commonly used:

• Power Plants
  Used extensively in boilers, superheaters, reheaters, and heat exchangers, alloy steel tubes ensure long service life under continuous thermal and pressure cycling.
• Petrochemical & Oil Refineries
  Ideal for high-temperature and high-pressure services, these pipes and tubes are used in process piping, catalytic reformers, furnace coils, and distillation columns.
• Chemical Processing Industries
  Resistant to acidic and corrosive media, alloy steel pipes handle chemical transfer, reaction vessels, and high-temperature fluid systems with ease and reliability.
• Fertilizer Plants
  Used in urea reactors, heat exchangers, and ammonia converters where chloride stress corrosion and thermal stability are critical.
• Nuclear & Thermal Power Systems
  Critical applications such as reactor coolant systems, steam generation, and containment piping rely on alloy steel materials for their creep resistance and metallurgical integrity.
