ASTM A179 L-Type Wound Finned Tube For HRSG And Boilers

Product Specifications

Attribute	Value
Base Tube Standard	ASTM A179
Type	Wound, L Type, LL Type, KL Type
Bare Tube Diameter	16mm-63mm
Fin Pitch	2.1mm-5mm
Fin Height	<17mm

Product Overview

ASTM A179 L-Type Wound Finned Tube is a cost-effective heat transfer solution designed for moderate-temperature applications. It features a seamless low-carbon steel base tube (ASTM A179) with L-shaped aluminum fins mechanically wound under tension. This robust construction creates maximum fin-to-tube contact area, delivering 25% higher heat transfer efficiency than bare tubes in boilers, economizers, and heat recovery units. Ideal for non-corrosive environments up to 150°C (302°F), it balances performance and budget with minimal maintenance.

Chemical & Mechanical Properties

Chemical Composition (ASTM A179 Base Tube)

Element	Content (%)	Role
Carbon (C)	≤ 0.06	Weldability
Manganese (Mn)	0.27-0.63	Strength
Phosphorus (P)	≤ 0.035	Purity
Sulfur (S)	≤ 0.035	Ductility
Silicon (Si)	≥ 0.10	Deoxidation
Thermal Conductivity	51.9 W/m*K (Base)	204 W/m*K (Fin)

Mechanical Properties (System)

Property	Base Tube (A179)	Aluminum Fin (1100)
Tensile Strength	≥ 325 MPa	95-125 MPa
Yield Strength	≥ 180 MPa	35-50 MPa
Max Service Temp.	260°C (500°F)	150°C (302°F)
Fin Bond Strength	-	> 35 MPa (Tested per ASTM E8)
Recommended Medium	Steam/Hot Water	Air/Gases

Key Applications & Value Highlights

Power Plant Boilers: Economizer sections for flue gas heat recovery.
HVAC Systems: Air heating coils in commercial ventilation units.
Industrial Dryers: Conveyor belt dryers for food/paper processing.
Thermal Oil Heaters: Secondary heat exchangers in hydraulic systems.
Biomass Energy: Low-pressure steam generators.

Why Choose Our Wound Fin Tubes?

30% Cost Saving: Most economical finned tube solution vs. extrusion/welding.
Easy Installation: Lightweight design reduces structural support needs.
Scale Resistance: Smooth aluminum fins minimize ash/fouling buildup.
Rapid Delivery: Standard sizes (OD 19-50mm, Length ≤ 12m) in stock.
