产品描述：列管式换热器 （tubular exchanger）是目前化工及酒精生产上应用**广的一种换热器。它主要由壳体、管板、换热管、封头、折流挡板等组成。所需材质 ，可分别采用普通碳钢、紫铜、或不锈钢制作。在进行换热时，一种流体由封头的连结管处进入，在管流动，从封头另一端的出口管流出，这称之管程；另一种流体由壳体的接管进入，从壳体上的另一接管处流出，这称为壳程。 Shell and tube heat exchanger, tubular exchanger) are the most widely used chemical and alcohol production of a heat exchanger. It is mainly composed of shell, tube plate, heat exchange tube, head, baffle and so on. The required materials can be made of ordinary carbon steel, copperorstainless steel. During heat transfer, a fluid enters through the joint pipe of the head, flows through the pipe and flows out of the outlet pipe at the other end of the head. Another fluid enters the shell by means of a tube, and flows out of another tube on the shell. This is called shell side. 主要特征：换热器种类繁多，单从化工行业中使用最广泛的产品来看，列管式换热器的使用最多，出现频率最高，列管式换热器主要分为固定管板式、浮头式和U型管三种，列管式换热器结构简单、坚固、适应性强，尤其在高温、高压和大型装置中应用更为普遍。 固定管板式换热器是列管式换热器中结构最简单的，因此使用比较普遍，固定管板式换热器主要是由圆柱形壳体、换热管、管板、封头和进出口组成。管束可以采用焊接法或胀接法固定，壳体上需要焊接法兰，方便清洗时或者检查时拆卸。端盖和壳体上有冷热进出口接管，冷热两种流体分别在管内流动。列管式换热器按照管束放置的位置可以分为立式和卧式，立式的结构是管束垂直地面，卧式恰恰相反。 列管式换热器结构简单，造价相对便宜，在一些领域很受欢迎。巩义市荣华换热器公司生产的换热器、列管式换热器广泛使用在石油、化学、电力等行业，凭借优质的质量保证设备正常运行。 There are many different kinds of heat exchanger and single from the perspective of the product of the most widely used in chemical industry, the use of shell and tube heat exchanger, the highest frequency, shell and tube heat exchanger is mainly divided into fixed tube plate, floating-head type and U type tube three, shell and tube heat exchanger of simple structure, strong, strong adaptability, especially in high temperature, high pressure and large equipment application is more common. The fixed tubeplate heat exchanger is the simplest structure in the tubular heat exchanger, so it is widely used. The fixed tubeplate heat exchanger is mainly composed of cylindrical shell, heat exchanger, tubeplate, seal head and inlet and outlet. The tube bundle can be fixed by weldingorexpansion joint, and the flange needs to be welded on the shell, which is convenient to be removed during cleaningorinspection. The end cover and the shell have a cold and hot inlet and outlet pipe, and the cold and hot fluids flow in the pipe respectively. The tubular heat exchanger can be divided into vertical type and horizontal type according to the position of the tube bundle. The vertical structure is the vertical ground of the tube bundle, while the horizontal type is just the opposite. Tubular heat exchangers are popular in some fields because of their simple structure and relatively low cost. The heat exchanger and tube heat exchanger produced by gongyi ronghua heat exchanger co., LTD are widely used in petroleum, chemistry, electric power and other industries.
