Description

ASTM A358 TP304H / 1.4948 Stainless Steel EFW Pipe Double Welded Pipe

ASTM A358 TP304H EFW pipe is an electric-fusion-welded, high-carbon (0.04–0.10%) stainless steel pipe. Manufactured from plate, it is solution-annealed for enhanced creep-rupture strength above 550°C. Specified under Class 1 for 100% radiography, it is designed for high-temperature, pressure-retaining services like boiler headers and refinery transfer lines. Choose ASTM A358 over ASTM A312 for welded pipe because A358 is exclusively designed for large-diameter, heavy-wall fabrication from formed plates using double-sided submerged arc welding (SAW). It enforces strict radiographic examination classes (e.g., Class 1 = mandatory 100% RT) critical for verifying weld integrity under high-temperature creep conditions.

Note: 304H also has a requirement for a grain size of ASTM No 7 or coarser.

ASTM A358 offers different classes based on non-destructive testing requirements. For high-temperature, critical service, Class 1 is usually mandatory:

  • Class 1: Fully radiographed (100% RT) along the entire weld length.

  • Class 2: Spot radiographically examined.

  • Class 3: Not radiographically examined (hydrostatic test only).

For high-temperature/pressure boilers, Class 1 is strictly recommended.

Applications

Because of the robust welding method and high corrosion resistance, this pipe is used in demanding environments:

  • Chemical Processing: Handling acids, sulfates, and chlorides.

  • Petrochemical Refineries: High-temperature hydrocarbon service.

  • Food Processing: Where cleanliness and corrosion resistance are vital.

  • Water Treatment: Desalination plants and wastewater treatment (resists chloride corrosion).

  • Power Generation: Flue gas desulfurization (FGD) systems.
