Product Overview

Serrated spiral HF (high-frequency) welding fin tubes are advanced heat exchangers designed to enhance thermal performance through a unique fin design. The combination of serrated fins and spiral configurations maximizes heat transfer while maintaining structural integrity. The fins are attached to the tube using high-frequency welding techniques, ensuring strong and durable connections while minimizing thermal distortion.

Design Features

Serrated Fins: Creates larger surface area and promotes turbulent flow for improved heat exchange efficiency
Material: Typically constructed from carbon steel, stainless steel, alloy or copper for durability and corrosion resistance
Spiral Configuration: Allows continuous fluid flow around the tube for enhanced heat transfer

ASTM A335 P9 Alloy Base Tube Specifications

This specification covers nominal wall and minimum wall seamless ferritic alloy-steel pipe suitable for high-temperature service. The pipe is suitable for bending, flanging, forming operations, and fusion welding. Selection depends upon design, service conditions, mechanical properties, and high-temperature characteristics.
