厂家如何增强列管式冷凝器的耐腐蚀性

人气:6 评论:0 日期:2019-01-11 10:00:04

列管式冷凝器的电化学的保护法在一定程度上可以分为阴极保护和阳极保护,在运行时其阴极保护主要是利用外加直流电源,这样就可以使得列管式冷凝器的金属表面上的阳极变为阴极而受到保护。这种方法消耗电量大,费用高,采用极少。阳极保护法是把被保护的设备接以外加电源的阳极,使金属表面生成钝化膜,从而达到保护。接下来冷凝器厂家带大家来看看列管式冷凝器的耐腐蚀性,希望对大家有所帮助。

The electrochemical protection method of tubular condenser can be divided into cathodic protection and anodic protection to a certain extent. In operation, the cathodic protection of tubular condenser mainly uses external DC power supply, so that the anode on the metal surface of tubular condenser can be changed into cathode and protected. This method consumes a large amount of electricity, costs a lot, and uses very little. Anodic protection method is to connect the protected equipment with the anode of the external power supply, so that passive film can be formed on the metal surface, so as to achieve protection. Next, let's take a look at the corrosion resistance of tubular condensers, hoping to help you.

1、列管式冷凝器在进行制作时采用耐腐蚀材料,这些材料的耐腐蚀性强,在进行操作时可以提高其设备的使用寿命,但这些高耐腐蚀性的材料价格昂贵,制造成本高,一次性投入的成本大,企业一般难以接受,推广困难。

1. The tubular condensers are made of corrosion-resistant materials, which have strong corrosion resistance and can improve the service life of their equipment when they are operated. However, these materials with high corrosion resistance are expensive in price, high in manufacturing cost and high in one-time investment, which are generally unacceptable to enterprises and difficult to popularize.

2、列管式冷凝器的金属表面,在一定程度上可以通过一定的涂覆方法,其覆盖一层耐腐蚀的涂料保护层,这样就可以有效的避免其金属表面和腐蚀介质的直接接触,这种技术方法经济有效,用于防止气体介质腐蚀,所用涂料大部分为有机高分子混合物溶液。人们逐渐向防油及防溶剂涂料、高温涂料、重防腐涂料及特殊环境用涂料方向发展。

2. To a certain extent, the metal surface of tubular condenser can be coated with a corrosion-resistant coating, which can effectively avoid the direct contact between the metal surface and the corrosive medium. This technology is economical and effective, and can be used to prevent the corrosion of gas medium. Most of the coatings used are organic polymer mixture solution. People are gradually developing toward oil-and solvent-resistant coatings, high temperature coatings, heavy-duty anti-corrosion coatings and coatings for special environments.

3、列管式冷凝器会在腐蚀性介质中,有效的加入少量的某些物质,而这些物质能使金属的腐蚀大大降低,甚至停止,这类物质称为缓蚀剂。缓蚀剂的加入应以不影响列管式冷凝器的生产工艺和产品质量为原则。

3. The tubular condenser can effectively add a small amount of certain substances in corrosive medium, which can greatly reduce or even stop the corrosion of metals. These substances are called corrosion inhibitors. The principle of adding corrosion inhibitor is not to affect the production process and product quality of tubular condenser.

列管式冷凝器在进行操作时需要隔离设备系统,然后将设备里面的水排放干净,在进行制作时采用其高压水清洗管道内存留的淤泥、藻类等杂质后,封闭系统。接上输送泵和连接导管,使清洗剂从列管式冷凝器的底部泵入,从顶部流出。

The tubular condenser needs to isolate the equipment system during operation, and then drain the water inside the equipment clean. After cleaning the mud, algae and other impurities in the pipeline with its high-pressure water, the system is closed. Connect the conveyor pump and the connecting duct so that the cleaning agent can be pumped into the bottom of the tubular condenser and out of the top.
