ASTM A213 TP347H Alloy-Steel Solid Fin Tube For Boiler

Product Overview

Helical solid fin tubes, also known as high frequency welding fin tubes, are manufactured using a specialized process that utilizes high-frequency electrical currents to fuse metal edges without additional filler materials.

Material Specifications

ASTM A213 TP347H (UNS S34709) are seamless austenitic steel tubes designed for applications in boilers, superheaters, and heat exchangers. Grades designated with 'H' provide superior creep-rupture strength at elevated temperatures.

Chemical Composition (%)

Grade	C	Mn	P	S	Si	Cr	Ni	Nb
TP347H	0.04-0.10	2.00	0.045	0.030	1.00	17.0-19.0	9.0-13.0	8×C-1.10

Mechanical Properties

Grade	Tensile Strength (min)	Yield Strength (0.2% Offset, min)	Elongation (min)	Hardness (max)
TP347H	75ksi (515 MPa)	30ksi (205 MPa)	35%	192 HBW / 200HV / 90 HRB

Product Advantages

Increased heat exchange area reduces heat transfer and metal flow
Excellent corrosion resistance, wear resistance, and thermal stability
Low contact thermal resistance with anti-ash capability
Reduces required installation space while maintaining high reliability
Enhanced stiffness and seismic performance

Applications

Ideal for power stations and high-temperature equipment in the oil industry, including:

Boilers and Steam Generators
Heat Exchangers and Furnaces
Economizers and Combustion Heaters
Large Air Coolers
Drier Heaters
