ASTM A335 P9 Chromium-Molybdenum Alloy Studded Finned Tubes for High-Temperature Furnace Applications

Product Description

ASTM A335 P9 Chromium-Molybdenum Alloy Studded Finned Tubes are high-performance tubes designed for demanding high-temperature applications in furnaces, boilers, and heat exchangers. Manufactured to meet ASTM A335 P9 standards, these tubes feature studded fins created through advanced high-frequency welding (HFW) technology, ensuring superior heat transfer efficiency and durability.

Material & Composition

ASTM A335 P9 tubes are made from chromium-molybdenum alloy steel, which provides excellent resistance to oxidation, corrosion, and high-temperature creep. The precise chemical composition ensures optimal performance in extreme conditions.

Mechanical Properties

These studded finned tubes exhibit exceptional mechanical properties, making them ideal for high-temperature and high-pressure environments.

Manufacturing Process

Our ASTM A335 P9 studded finned tubes are produced using high-frequency welding (HFW) technology, ensuring precise fin attachment and excellent thermal conductivity. The seamless base tube is manufactured through hot extrusion and cold drawing, guaranteeing uniform structure and dimensional accuracy.
