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.

Studded fin tubes for industrial heat exchangers
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
