| High Light | ASTM A249 TP304L fin tube ，stainless steel extruded fin tube ，air-cooled exchanger fin tube | ||
This is a stainless steel heat transfer tube. The core tube meets ASTM A249 for TP304L, a low-carbon, corrosion-resistant austenitic stainless steel. Its fins are formed by extruding the tube wall itself, creating a seamless, integral one-piece structure. This makes the tube efficient and durable, ideal for demanding heat exchanger applications where reliability is critical. It is commonly used in industries like chemical processing, power generation, and marine engineering for equipment such as boilers, heaters, and coolers. The design ensures robust performance in corrosive environments.
