Description
Welded 304/L Stainless Steel Tubes ASTM A249 For Heat Exchanger Pipe
Product Introduction

The Welded 304/L Stainless Steel Tube, manufactured according to ASTM A249 / ASME SA249, is a high-performance austenitic stainless steel pipe designed for heat exchangers, condensers, and evaporators. Produced by Wuxi Korer Stainless Steel Co., Ltd., this tubing features a bright annealed surface, precise dimensional control, and excellent corrosion resistance. The low-carbon version, 304L, minimizes intergranular corrosion after welding and offers superior durability in high-temperature and corrosive environments. These tubes are widely used in power generation, petrochemical, food, and pharmaceutical industries.

Applications
  • Heat exchangers and condensers in thermal, chemical, and petrochemical plants
  • Desalination, HVAC, and refrigeration systems
  • Pharmaceutical and food processing pipelines
  • Automotive and hydraulic exhaust systems
  • General industrial fluid transfer and mechanical structures
Advantages
  • Excellent corrosion resistance in various acidic and chloride environments
  • Low carbon (304L) prevents carbide precipitation during welding
  • High heat resistance and oxidation stability up to 870°C
  • Smooth internal surface for better heat transfer and fluid flow
  • Full compliance with ASTM A249 / ASME SA249 standards and ISO 9001 quality management

FAQ
Q1: What's the difference between 304 and 304L?
A: 304L contains less carbon, improving weldability and corrosion resistance in welded structures.
Q2: Can these tubes be used for food or pharmaceutical applications?
A: Yes, the smooth inner surface and hygienic properties make them suitable for sanitary systems.
Q3: What testing methods are applied?
A: Each tube undergoes Eddy Current, Hydrostatic, and Chemical Composition testing to ensure full compliance.
