Welded Stainless Steel Pipe for Chemical Industry ASME SA249 – Acid-Resistant & Long-Lasting
Product Introduction:
The Welded Stainless Steel Pipe, manufactured according to ASME SA249 / ASTM A249 standards, is a high-quality austenitic stainless steel tube designed for chemical, petrochemical, and industrial applications. Made from 316 stainless steel, this pipe offers superior corrosion and acid resistance, high mechanical strength, and durability, making it ideal for transporting aggressive chemicals, acids, and alkaline fluids. Produced by Wuxi Korer Stainless Steel Co., Ltd., the pipe undergoes precision TIG welding and bright annealing, resulting in a smooth internal surface that ensures hygienic fluid transfer, prevents fouling, and provides long-term reliable performance in demanding chemical environments.
Applications:
-
Chemical and petrochemical plants for transporting acids, alkalis, and corrosive fluids
-
Refineries and oil & gas pipelines
-
Evaporators, heat exchangers, and condensers in industrial systems
-
Pharmaceutical and biotechnology piping systems
-
Marine and desalination piping systems exposed to harsh chemical environments
-
Industrial high-pressure fluid pipelines
Advantages:
-
Excellent acid and corrosion resistance for safe operation in harsh chemical environments
-
Long-lasting durability with minimal maintenance requirements
-
Bright annealed surface ensures smooth flow, prevents contamination, and reduces fouling
-
High mechanical strength suitable for moderate to high-pressure applications
-
Excellent weldability and formability for customized piping installations
-
Compliant with ASME SA249 / ASTM A249 standards, ensuring international quality and reliability
