Product Description

Welded Helical Serrated Finned Tubes ASTM A312 TP304H For Economizer Boiler

Definition

Serrated spiral fin tubes are essential components of advanced heat exchangers. The combination of serrated fins and spiral configurations maximizes heat transfer while maintaining structural integrity. Tube and fin materials may be carbon, stainless steel, copper, ferritic alloy or austenitic alloy steel and can be of similar or dissimilar material combinations. The fin strip is cut or serrated at equally spaced intervals, with fins attached to the tube using high-frequency welding techniques, ensuring strong and durable connections while minimizing thermal distortion.

Details of ASTM A312 TP304H Base Tubes

ASTM A312 specification covers seamless, straight-seam welded, and heavily cold worked welded austenitic stainless steel pipe intended for high-temperature and general corrosive service. Welded (WLD) pipe is made using an automatic welding process with no addition of filler metal during the welding process.

Grades TP304H, TP309H, TP309HCb, TP310H, TP310HCb, TP316H, TP321H, TP347H, and TP348H are modifications of standard grades and are specifically intended for high-temperature service.

Chemical Composition (%)

S30409	0.04-0.10	2.00	0.045	0.030	1.00	18.00-20.00

Mechanical Properties

Grade	Tensile Strength, min	Yield Strength (0.2% Offset, min)	Elongation min. %	Heat Treating Temperature min.
S30409	75ksi (515 MPa)	30ksi (205 MPa)	35%	1900°F [1040°C]

Advantages

The serrated fins create a larger surface area and promote turbulent flow, significantly improving heat exchange efficiency
The unique fin shape and spiral configuration enhance thermal performance compared to traditional fin tubes
Internal flow is more smooth with reduced flow resistance
Robust construction ensures strong joints, providing durability and reliability in demanding environments
Excellent corrosion resistance, wear resistance, and low contact thermal resistance
High stability and long service life
Simple and economical installation with minimal maintenance requirements

Applications

These finned tubes are suitable for a wide range of industrial applications:

Heat exchangers, boilers, furnaces and refineries: Ideal for oil coolers, condensers, and evaporators
Power Generation: Commonly used in power plants for efficient heat recovery and steam generation
HVAC Systems: Improves energy efficiency in heating, ventilation, and air conditioning systems
Chemical Processing: Critical for reactors and heat exchangers requiring optimal thermal performance
