Yuhong Enamel Co., Ltd. is a joint venture of Hebei and Hongkong with a registered capital of 6 million yuan. Covering 10000 m2, it is located in the Zaoqiang county seat, a favorable site with convenient communications. Its leading products enamel heat conduction elements for air preheaters of boilers in power plants and for fume heaters of fume desulfurization equipment are national patent products(Patent No.: ZL95207529.6 and ZL 02 2 45787.9), and have passed technical certification by relative dept. (Certificate No.: 98.018).        At beginning of its foundation, the company propounded a tenet of "Expand sales with quality and make friends with sincerity". After several years of unremitting efforts, our products have been adopted by dozens of power plants and petrochemical companies and got their recognition. Excessibe sulfur and dust in fume discharged by boilers using fuel of coal and oil in power plants can lead to serious corrosion and dust accumulation of heat conduction elements at low temperature section of the air preheater, influencing normal operation of the boiler and reducing energy efficiency. Because enmel heat conduction elements have smooth surface, resistant to corrosion and easy to wash, they can fundamentally resolve this problem, prolong life lime of the air preheater, reduce working cost of the boiler and increase comprehensive benefits of the power plant or petrochemcial company. 　　 Except enamel, we can also produce heat conduction elements of other materials such as plain carbon steel, kaodeng steel, etc. We have one flow line to produce all kinds of corrugated plates with annual output of 2400 tons, one plate type automation production line for heat conduction elements with annual output of 2400 tons, two horizontal medium frequency automatic lines with annual output of 2000 tons of enamel pipes of largest length of 13m and largest diameter of 400mm, and two well type elctrical resistance furnace with annual output of 2000 tons of enamel pipes of largest diameter of 400mm and largest length of 5.5m. Professional high-precison equipment and advanced rational technics paved a solid basis for product quality. The company pursues perfection in technology, employing 10 people with senior technical title and 20 technicians, training working technical personnel every year to provide stronger technical guarantee for product quality. In October, 2001, the company successfully passed ISO9001 international quality system certification. 　　 On the basis of enamel heat conduction elements, the company succeeded in another key program, the enamel tube bundle applied in desulfurization by electricity plants, namely, the 12m long enamel finned tube, whose technics is original in China and performance is advanced in the world and marketing prospect is very promising. 　　 Yuhong Company always makes every firm step forward with a positive attitude. We will always cooperate with every customer sincerely with first-rate products, proper prices, satisfying after service and friendly public relationship.
