镀锌管在生活中常见的应用

镀锌钢管的呈现,曾经给咱们带来便当,但是跟着年代的开展,镀锌钢管已逐渐被筛选,淡出历史的舞台。但你知道镀锌钢管是什么吗?镀锌钢管有着怎样的历史呢?镀锌钢管理论重量表又是怎样的?下面就跟随小编一起来了解镀锌钢管吧。

The presentation of galvanized steel pipe once brought us convenience, but with the development of the times, galvanized steel pipe has been gradually screened out of the stage of history. But do you know what galvanized steel pipe is? What's the history of galvanized steel pipe? What's the theoretical weight table of galvanized steel pipe? Let's learn about galvanized steel pipe with a small editor.
镀锌钢管是什么
What is galvanized steel pipe
镀锌钢管分为冷镀锌管、热镀锌管,开端镀锌钢管作为水管运用,几年后管内就产生了大量锈垢,流出黄水不仅污染洁具,并且夹杂着不光滑内壁滋生的细菌,锈蚀造成水中重金属含量过高,严重危害人体健康。所以在六七十年代,发达国家开端研发新型管材,并陆续禁用镀锌钢管。我国也发文明确从2000年起禁用镀锌钢管,现在大多新建小区已很少运用镀锌钢管了,但也有些小区还在运用镀锌钢管。
Galvanized steel pipes are divided into cold galvanized pipes and hot galvanized pipes. At the beginning, galvanized steel pipes were used as water pipes. After a few years, a large number of rust scales were produced in the pipes. The yellow water not only polluted the sanitary wares, but also was mixed with the bacteria growing in the uneven inner wall. The corrosion caused the high content of heavy metals in the water, seriously endangering human health. Therefore, in the 1960s and 1970s, developed countries began to develop new pipes, and gradually banned galvanized steel pipes. In China, galvanized steel pipes have been banned since 2000. Nowadays, galvanized steel pipes are rarely used in most new communities, but some are still using galvanized steel pipes.
热镀锌钢管
Hot dip galvanized steel pipe
热镀锌钢管是使熔融金属与铁基体反应而产生的合金层,从而使基体和镀层二者相结合。热镀锌是先将钢管进行酸洗,去除钢管表面的氧化铁,酸洗后送入氯化铵或氯化锌水溶液或氯化铵和氯化锌混合水溶液槽中进行清洗,然后再送入到热浸镀槽中。热镀锌具有镀层均匀、附着力强、运用寿命长等长处。热镀锌钢管基体与熔融镀液发生杂乱的物理及化学反应,形成耐腐蚀且结构紧密的锌一铁合金层。合金层与纯锌层、钢管基体融为一体,其耐腐蚀功能强。
The hot-dip galvanized steel pipe is an alloy layer formed by the reaction of molten metal and iron matrix, so that the matrix and coating are combined. Hot dip galvanizing is to pickle the steel pipe, remove the iron oxide on the surface of the steel pipe, and then send it to the solution tank of ammonium chloride or zinc chloride or the mixed solution tank of ammonium chloride and zinc chloride for cleaning, and then send it to the hot dip galvanizing tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The matrix of hot-dip galvanized steel pipe reacts with the molten bath in a disordered physical and chemical way, forming a zinc iron alloy layer with corrosion resistance and tight structure. The alloy layer is integrated with pure zinc layer and steel pipe matrix, which has strong corrosion resistance.
冷镀锌钢管
Cold galvanized steel pipe
冷镀锌钢管便是电镀锌,镀锌量很少,只要10-50g/m2,其自身的耐腐蚀性比热镀锌刚管差许多。为了保证质量,正规的镀锌管生产厂家一般不选用电镀锌,只要那些规划小、设备陈旧的小企业才会选用电镀锌,而他们的价格天然也比较便宜。冷镀锌钢管的镀锌层是电镀层,锌层与钢管基体独立分层。锌层较薄,简单附着在钢管基体上,比较容易脱落,其耐腐蚀功能差。建设部早已正式下文,筛选技术落后的冷镀锌刚管,禁绝将其作给水、煤气管。在新建住所中,也严令禁止运用冷镀锌钢管作为给水管。
The cold galvanized steel pipe is galvanizing, the amount of galvanizing is very small, as long as 10-50g / m2, its corrosion resistance is much worse than the hot galvanized steel pipe. In order to ensure the quality, the regular galvanized pipe manufacturers generally do not choose galvanizing, as long as those small enterprises with small planning and old equipment will choose galvanizing, and their prices are naturally cheaper. The galvanized layer of cold galvanized steel pipe is electroplated layer, and the zinc layer is separated from the steel pipe substrate. The zinc layer is thin and simply attached to the steel pipe matrix, which is easy to fall off and has poor corrosion resistance. The Ministry of construction has already formally selected the backward cold galvanized rigid pipes, which are forbidden to be used as water supply and gas pipes. It is also strictly prohibited to use cold galvanized steel pipes as water supply pipes in new residences.
镀锌钢管使用
Use of galvanized steel pipe
镀锌钢管表面有热浸镀或电镀锌层的焊接钢管。镀锌可增加钢管的抗腐蚀能力,延伸运用寿命。镀锌钢管用途很广,除作输水、煤气、油等一般低压力流体的管线管外,还用作石油工业特别是海洋油田的油井管、输油管,化工焦化设备的油加热器、冷凝冷却器、煤馏洗油交换器用管,以及栈桥管桩、矿山坑道的支撑架用管等。热镀锌带钢管被广泛使用于各类现代制作工业。
Welded steel pipe with hot dip or electro galvanized coating on the surface of galvanized steel pipe. Galvanizing can increase the corrosion resistance of steel pipe and extend its service life. Galvanized steel pipes are widely used, not only as pipelines for water delivery, gas, oil and other general low-pressure fluids, but also for oil well pipes and oil pipelines in petroleum industry, especially in offshore oil fields, oil heaters, condensing coolers, coal distillate wash oil exchangers for chemical coking equipment, trestle pipe piles, support frame pipes for mine tunnels, etc. Hot dip galvanized steel pipe is widely used in all kinds of modern manufacturing industries.
