ASTM A376 TP347H SS HF Welded Fin Tube for Radiadores
This page is about ASTM A376 TP347H high frequency welded stainless steel fin tube with fin general material carbon / alloy / stainless steel , we sell these fin tubes more than 33 years and sell in over 70 countries.
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.
These 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. HFW Fin Tube called solid type fin tube, this type fin tube can improving heat transfer efficiency much more than bare tube.
HFW Fin tube has many types: Serrated Fin Tube , Flat Fin Tube, Studded Fin Tube .
