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

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.

Mechanical Properties

Property	Value
Tensile Strength	415 MPa (60,000 psi) min
Yield Strength	205 MPa (30,000 psi) min
Elongation	30% min (in 2 inches or 50 mm)
Hardness	≤ 197 HBW (Brinell Hardness)

Material maintains strength and integrity at elevated temperatures with excellent weldability.

Industrial Applications

Power Generation: Boilers, superheaters, reheaters, and economizers in power plants
Petrochemical: Process heaters, heat exchangers, and waste heat recovery systems
Oil & Gas: Gas cooling systems, air coolers, and fired heaters
Refining: Crude oil heaters, catalytic reforming units, and hydrogen plants
Industrial Heating: Air heaters and heat recovery systems for process applications
High-Temperature Systems: Incinerators and chemical processing equipment
