Description

ASME SA312 TP347H Stainless Steel Seamleess Pipe with SS Fin Strip for Heater


Product Overview

ASME SA312 TP347H Stainless Steel Fin Tube is manufactured by applying stainless steel fin strips onto a seamless TP347H pipe, typically using high-frequency welding (HFW) or embedded finning techniques. It’s ideal for high-temperature heater applications requiring superior creep strength, oxidation resistance, and structural stability under thermal stress.



Chemical Composition

Base Tube: ASME SA312 TP347H

Element Composition (%)
Carbon (C) 0.04–0.10
Manganese (Mn) ≤ 2.00
Phosphorus (P) ≤ 0.045
Sulfur (S) ≤ 0.030
Silicon (Si) ≤ 1.00
Chromium (Cr) 17.0–19.0
Nickel (Ni) 9.0–13.0
Columbium (Nb) 10×C to 1.10 (stabilizer)

Fin Strip: Stainless Steel (typically SS304 or SS347)

Element Composition (%)
Chromium (Cr) 18.0–20.0
Nickel (Ni) 8.0–12.0
Carbon (C) ≤ 0.08 (304) or ≤ 0.10 (347H)
Manganese (Mn) ≤ 2.00
Silicon (Si) ≤ 1.00

Mechanical Properties

SA312 TP347H Base Tube

Property Value
Tensile Strength ≥ 515 MPa
Yield Strength ≥ 205 MPa
Elongation ≥ 35%
Hardness (HB) ≤ 217 HB
Operating Temperature Up to 1000°C

Fin Strip (Stainless Steel)

Property Value
Tensile Strength 500–750 MPa
Oxidation Resistance Excellent >800°C
Corrosion Resistance Excellent

Advantages

  • Superior High-Temperature Strength: TP347H performs well under creep conditions in high heat zones.

  • Excellent Weldability: Seamless tube and fin strip have stable austenitic structure ideal for HFW or TIG welding.

  • Resistance to Oxidation & Carburization: Both base and fins resist scale formation at elevated temperatures.

  • Stable Grain Structure: Niobium stabilizer in TP347H prevents intergranular corrosion and ensures long service life.

  • Low Thermal Stress Fatigue: Suitable for cyclic operations in furnaces and fired heaters.

Typical Applications

  • Petrochemical Heaters

  • Fired Heaters in Refineries

  • Steam Superheaters

  • Radiant and Convection Tubes

  • Furnace Coils and Heat Recovery Units

  • High-Pressure Boilers and Reheat Coils
