Product Description

The ASTM A335 P9 Welded Helical Serrated Finned Tube with Carbon Steel Fins is a specialized heat exchanger tube designed for high-temperature and high-pressure applications in power plants and industrial processes.

Key Features
  • Welded Construction: Fins are securely welded to the base tube for strong mechanical bond and efficient heat transfer
  • Helical Design: Spirally wound fins maximize surface area for superior heat exchange
  • Serrated Fin Profile: Notched design enhances heat transfer by creating fluid turbulence
  • Carbon Steel Fins: Cost-effective solution with excellent thermal conductivity
  • High-Temperature Resistance: P9 alloy steel base tube withstands extreme operating conditions
