ASME SA423 GR.1 Low Alloy Steel Seamless Boiler Tubes For Superheater Water Wall
Product Description

ASME SA423 Grade 1 Electric Resistance Welded (ERW) tube is a low-alloy steel tube manufactured using the electric resistance welding process. This specification covers low-alloy steel tubes designed for high-temperature and high-pressure service, particularly in boilers and heat exchangers, with excellent resistance to atmospheric corrosion.

Standards & Specifications
  • ASME SA423: Standard specification for seamless and welded low-alloy steel tubes for boilers and superheaters
  • Grade 1: Optimized for high-temperature service applications
  • Complies with ASME Boiler and Pressure Vessel Code (BPVC) Section II for material properties
Testing & Inspection
  • Hydrostatic testing, ultrasonic testing (UT), or eddy current testing to ensure weld integrity
  • Chemical and mechanical property verification per ASTM/ASME standards
Key Advantages
  • Cost-Effective: More economical than seamless tubes while maintaining high strength and durability
  • High-Temperature Resistance: Chromium-molybdenum (Cr-Mo) alloy provides excellent creep resistance up to 450°C (850°F)
  • Good Weldability: ERW process ensures strong, uniform welds without filler metals
  • Consistent Quality: Precise dimensional control for reliable performance in pressure applications
  • Corrosion Resistance: Resists oxidation and scaling in steam/high-heat environments
  • ASME Compliance: Meets strict Boiler & Pressure Vessel Code standards for safety
Primary Applications
  • Power Generation: Boiler tubes in thermal power plants, superheaters & reheaters, heat exchangers & condensers
  • Oil & Gas / Petrochemical: Refinery heat exchangers, high-temperature pipelines, furnace components
  • Industrial Process Equipment: Chemical processing units, pressure vessels, thermal fluid systems
  • District Heating Systems: Hot water supply pipelines, steam distribution networks
