不锈钢冷凝器参考标准和钢管选用及其焊接

人气:1 评论:0 日期:2019-07-27 23:16:00

不锈钢冷凝器,其是冷凝器中的一种,而且其对我们来讲,也是非常值得进行熟悉和了解的,因为只有这样,才能认识不同冷凝器种类,并同时,来拓宽自己的知识面,增加这方面的专业知识,这样,才能不断进步和有新的收获。

Stainless steel condenser is a kind of condenser, and it is worth knowing and understanding for us, because only in this way can we know different types of condenser, and at the same time, to broaden our knowledge and increase professional knowledge in this field, so as to make continuous progress and have new income. Win. 1.不锈钢冷凝器中的不锈钢

1. Stainless steel in stainless steel condenser


不锈钢冷凝器中的不锈钢,其是一种金属材料,是能够耐空气、蒸汽以及水等这些介质的腐蚀,此外,还能够耐酸、碱和盐的化学腐蚀。不过,需要注意的是,如果是能够耐弱腐蚀的不锈钢,一般将其称之为不锈钢,而能够耐化学介质腐蚀的钢,称之为耐酸钢,它们在化学成分上,是有一定差异的。

Stainless steel in stainless steel condenser is a kind of metal material, which can resist the corrosion of air, steam and water. In addition, it can also resist the chemical corrosion of acid, alkali and salt. However, it should be noted that if stainless steel can resist weak corrosion, it is generally called stainless steel, and steel that can resist chemical medium corrosion is called acid-resistant steel. Their chemical composition is different.


2.不锈钢冷凝器的耐腐蚀性,是由什么来决定的?此外,其可用于四氢呋喃吗?

2. What determines the corrosion resistance of stainless steel condensers? In addition, can it be used for tetrahydrofuran?


不锈钢冷凝器,其的耐腐蚀性,主要是由钢中所含合金元素来决定的,而不是其它因素或方面。这一种冷凝器,是可用于四氢呋喃的,而且,是没有任何问题的,因为其具有非常好的耐腐蚀性。

The corrosion resistance of stainless steel condenser is mainly determined by the alloy elements contained in the steel, not by other factors or aspects. This kind of condenser can be used for tetrahydrofuran, and there is no problem because it has very good corrosion resistance.


3.冷凝器中钢管种类和相关标准

3. Types of Steel Tubes in Condensers and Relevant Standards


冷凝器中的不锈钢冷凝器这一种,其材质是为不锈钢,所以,其是会用到钢管这一部件的,并且,我们需要知道的是,在钢管种类上,一般是采用无缝钢管,因为这样可以避免出现裂纹或开裂等问题,从而,来保证冷凝器能够正常使用。

The stainless steel condenser in condenser is made of stainless steel, so it can be used in steel pipe. What we need to know is that seamless steel pipe is generally used in the type of steel pipe, because it can avoid cracks or cracks, so as to ensure that the condenser can be used. Normal use.


不锈钢冷凝器的相关标准,其是有很多的,不过其中常用的,是GB/T 30066-2013《热交换器和冷凝器用铁素体不锈钢焊接钢管》这一个。而且,该标准在钢管的尺寸、外形、重量、技术要求、试验方法、检验规则、包装、标志和质量上,都是有详细规定的。

There are many relevant standards for stainless steel condensers, but the most commonly used one is GB/T 30066-2013 "Ferritic stainless steel welded pipe for heat exchanger and condenser". Moreover, the standard has detailed provisions on the dimensions, shape, weight, technical requirements, test methods, inspection rules, packaging, marking and quality of steel pipes.


此外,这一标准,是参考了ASTM A268/A268M-2010《通用无缝和焊接铁素体与马氏体不锈钢管》和JIS G 3463-2006《锅炉与换热器用不锈钢钢管》这两个标准,从而来得到的。所以,其是有很好的实用性的。

In addition, this standard is obtained by referring to ASTM A268/A268M-2010 "General Seamless and Welded Ferrite and Martensitic Stainless Steel Pipe" and JIS G 3463-2006 "Stainless Steel Pipe for Boiler and Heat Exchanger". Therefore, it has good practicability.


4.不锈钢冷凝器的焊接

4. Welding of Stainless Steel Condenser


不锈钢冷凝器的焊接,其也是一重要工作,所以,也是需要有足够重视的,其在操作上,是有一些关键点的,比如,不锈钢的焊接部位,电烙铁应能够将温度提升到规定温度上,而且,应是为母体温度,而不是电烙铁的温度。此外,还要能够保证焊接及焊缝质量,没有任何焊接问题,以免影响到不锈钢冷凝器的正常使用。

Welding of stainless steel condenser is also an important work, so it also needs to be paid enough attention to. There are some key points in its operation. For example, welding parts of stainless steel, electric soldering iron should be able to raise the temperature to the specified temperature, and it should be the parent temperature, not the temperature of electric soldering iron. In addition, the quality of welding and welding seam should be guaranteed without any welding problems, so as not to affect the normal use of stainless steel condenser.
