Product Overview

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

Material Composition (ASTM A335 P9)

Element	Composition (%)
Carbon (C)	0.15 max
Manganese (Mn)	0.30-0.60
Phosphorus (P)	0.025 max
Sulfur (S)	0.025 max
Silicon (Si)	0.50-1.00
Chromium (Cr)	8.00-10.00
Molybdenum (Mo)	0.90-1.10

Composition optimized for high-temperature strength, oxidation resistance, and corrosion resistance.
