ASTM A269 TP304L Stainless Steel Extruded Fin Tube for Calderas
YUHONG Group can handle kinds of industry projects and supply variety of extruded fin tubes in the industry. All of our products are domestically sourced, developed, and produced, that means our customers have immediate access to exactly the products they need for their particular application. What´s more, and we can make sure that you can get products with highest quality and manufacturing standards and a local, concerned, customer service presence.
This page is about ASTM A269 TP304L Extruded Single Metal Gombined Metal stainless steel fin tube with fin general material copper / aluminum, we sell these fin tubes more than 33 years and sell in over 70 countries.
Fin tubes are used in many different industries. Fin tubes can use at very high temperatures possible because the strong connection between fin and base tube prevents loosening of fin because of heat stress, oxidization, corrosion etc. This extruded finned tubes configuration can be used in practically any heat transfer applications, and especially suited for high temperature, high pressure applications. And these tubes are used with a wide range of material such as carbon steel, low alloys steel and stainless steel for corrosive flue gas or high temperatures.
