Product Overview

Studded fin tubes, also known as nail head tubes or nail-like ribbed tubes, are widely used in petrochemical industries, particularly in the convection chambers of tubular furnaces to enhance heat transfer effects.

Design Features

Studded Fins: Protruding fins increase surface area for heat transfer and promote turbulent flow
Material: Constructed from durable materials including carbon steel, stainless steel, alloy or copper
Robust Structure: Studs arranged in specific formations for effective heat transfer in high-pressure applications

ASTM A213 T9 Alloy Specifications

ASTM A213 covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes, including Grade T9.

Chemical Composition (%)

Grade	C	Mn	P	S	Si	Cr	Mo
T9	0.15	0.30-0.60	0.025	0.025	0.025-1.00	8.00-10.00	0.90-1.10

Mechanical Properties

Grade	Tensile Strength,min	Yield Strength (0.2%Offset,min)
T9	60ksi (415 MPa)	30ksi (205 MPa)
