ISO9001 فولاد کربن کتل H Fin لوله برای H-نوع Fined لوله ای اقتصادی
Product Description H-type finned tubular economizer technology is a high-efficiency heat exchange economizer assembled by using H-type finned tubes (also known as H-type finned tubes, ribbed tubes, and sheet tubes). [1] Wear resistance: Wear resistance, can improve the wear life by 3-4 times. [2] Less ash accumulation: The reasons why H-type fins do not accumulate dust are: ① H-type fins are welded on both sides of the pipe that are not easy to accumulate dust, and the air
عنصر تبادل گرما دیگ کارآمد با شکل H لوله بالدار با بالدار مستطیل
Product Description The heat exchange element H-shaped fin tube is also called H-shaped rib tube, which is mainly to weld together two pieces of steel sheet with arc in the middle symmetrically and the plain tube to form a fin (rib). The front shape is quite similar to the letter "H", so it is called H-shaped fin tube. The two fins of H-shaped fin tube are rectangular, approximately square, and its side length is about 2 times the diameter of the light tube, which belongs to
