Ventilation pipe design task, is to organize a reasonable air flow, processing galvanized sheet duct, to ensure the effectiveness of the use of the premise, so that the project initial investment and most of the cost of operation and maintenance. Therefore, galvanized duct board factory, ventilation ducts design is reasonable, Bayannao'er galvanized sheet duct, directly affect the entire ventilation, air-conditioning engineering construction and use of technical and economic results. Thus, the design of ventilation ducts and consider a variety of issues important enough. Total plate duct flange without flange, also known as duct, its production in the form of more efficient than the traditional rectangular duct processing speed, more convenient and less air leakage rate. Langfang galvanized sheet duct | Yanda air conditioning | duct long-term supply of galvanized sheet provided by the Wu County Yanda air-conditioning plant. Langfang galvanized sheet duct | Yanda air conditioning | long-term supply of galvanized sheet duct is Wu County Yanda air-conditioning plant (www.wcydkt.com) (www.wcydkt.com) this year introduced a new upgrade, the above picture only for information, please call Tel picture on this page or to obtain the latest information, contact: Wu Yusong.
