Tengzhou City Haiyuan Heat Technology Co., Ltd. is the designated national production D1, D2 grade pressure vessel manufacturers, scientific research, design, manufacture, installation, sales, production in one of the producers. The company has an experienced team of experts in the heat and electrical energy-efficient equipment design, including senior officers Title 10, intermediate grade 19, while recruiting a number of university graduates in recent years, and long-term employment of graduates, the formation of a Support new combination of old, school-enterprise integration, with strong technical strength of the development team. Shell and tube (also known as the column tube) heat exchanger shell and tube heat exchanger is the main case, bundle, consisting of tube plate and seal top portion of the housing mostly round, the interior is equipped with parallel tubes or spiral , fixed at both ends of the tube bundle plate. Carried out within the shell and tube heat exchanger of the two fluids, a flow in the pipe, its stroke is called the tube; a flow in the tube, called a shell of its travel. Bundle of the wall is the heat transfer surface. Tubes of different models, the process is generally 16mm 20mm or 25mm diameter three models, the wall thickness of 1mm, 1.5mm, 2mm and 2.5mm. Import heat exchanger, the diameter of the minimum possible to 8mm, a wall thickness of only 0.6mm. Greatly improving the heat transfer efficiency, in 2012 to gradually promote the domestic market is also open. Shell and tube heat exchangers, spiral bundle designed to maximize the effect of increased turbulence, increase heat transfer efficiency. Asymmetrical design of the internal shell and tube layer can be up to 4.6 times. This asymmetrical design, determine its steam - widely used in the field of water heat exchanger. The maximum heat transfer efficiency can reach 14000w / m2.k, greatly improving production efficiency and cost savings. Contact QQ: 3058594586
