ASTM A312 TP304H Stainless Steel Pipe With SS Fin Strip, Serrated Fin Tube For Furnace
Product Overview
ASTM A312 TP304H serrated fin tube is manufactured from high-temperature stainless steel pipe with stainless steel fin strips mechanically or resistance-welded onto the tube surface. The serrated fins improve heat transfer by disrupting the boundary layer of gas flow, making them ideal for high-temperature furnace and heater applications.
