304 / 316L / 317L Stainless Steel U Tubes for Heater (ASME SA688 Compliant)
304 / 316L / 317L Stainless Steel U Tubes are engineered for high-temperature heating applications requiring exceptional corrosion resistance and pressure tolerance. These precision-formed U-shaped tubes are essential components in heat exchangers, boilers, and industrial heaters for optimal thermal management. Manufactured to ASME SA688 standards, they deliver reliable performance in power generation, chemical processing, and oil & gas applications.
Material Specifications
  • AISI 304 Stainless Steel: Versatile austenitic stainless steel offering excellent corrosion resistance and formability. Ideal for general-purpose heating systems with good oxidation resistance at elevated temperatures.
  • AISI 316L Stainless Steel: Low-carbon variant with superior chloride resistance, making it perfect for marine environments and chemical processing. Features enhanced weldability for U-tube fabrication.
  • AISI 317L Stainless Steel: High-molybdenum alloy providing exceptional acid resistance for harsh chemical environments. Delivers maximum durability in extreme temperature and pressure conditions.

Frequently Asked Questions
What distinguishes 304, 316L, and 317L stainless steel for U-tubes?
304 is general-purpose stainless steel, while 316L offers superior chloride resistance for marine/chemical use. 317L provides enhanced acid resistance with higher molybdenum content for extreme environments.
Are these U-tubes suitable for high-temperature service?
Yes, 304 performs well to 870°C (1598°F), while 316L/317L maintain superior heat resistance in aggressive conditions.
Can these tubes withstand desalination plant conditions?
316L and 317L are specifically engineered for desalination applications, with exceptional resistance to seawater corrosion.
What pressure ratings do these tubes support?
Pressure capacity depends on design specifications, with 316L/317L generally offering higher pressure tolerance than 304, especially at elevated temperatures.
Are custom sizes available?
Yes, we provide fully customized U-tube dimensions to meet specific heat exchanger or heater system requirements.
