ASME SA213 Seamless T12 HF Welding Finned Tube for Radiadores
YUHONG Group can handle kinds of industry projects and supply variety of welding 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 ASME SA213 TP12 High Frequency Welded(HFW Fin Tube), it also called solid type fin tube,use steel or stainless steel strip or steel round bar/rod directly welded on the pipe /tube surface. And HFW fin tube can improving heat transfer efficiency much more than bare tube. Due to the welding tightly of the fins to the base pipe / tube, these finned tubes can be often used in vibrating conditions.
HFW Fin tube has many types: Serrated Fin Tube , Flat Fin Tube, Studded Fin Tube .And they are used in many different industries. They 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. We YUHONG sell these fin tubes more than 33 years and sell in over 70 countries.
