  • 你知道怎么清洗不锈钢法兰吗?
  • 本站编辑:杭州崇贤重型机械有限公司发布日期:2021-06-25 16:30 浏览次数:
一般情况下不锈钢是法兰比较主要的材料,它比较被关注的地方就在于它的质量。这也是不锈钢法兰厂家生产中比较重要的话题。那么如何正确迅速清洗掉法兰上残留的污渍呢?
Generally speaking, stainless steel is the most important material for flanges. The most important concern is its quality. This is also the most important topic in the production of stainless steel flange manufacturers. Then how to clean the residual stains on flanges correctly and quickly?
法兰1
制造法兰比较常用的就是304不锈钢。这个材料制成的法兰于会在20℃下,并且在10%硝酸中被腐蚀的速度为每年小于0.1毫米;在10%沸醋酸中被腐蚀速度为每年小于0.1毫米;在50%柠檬酸中被腐蚀速度为每年小于0.1毫米;20%氢氧化钾中被腐蚀速度为每年小于0.1毫米。而在60℃下80%磷酸的中被腐蚀速度还是为每年小于0.1毫米;但在50℃下2%硫酸中的腐蚀速度则为每年0.016毫米。所以采用内衬由冷轧不锈钢带焊接而成的不锈钢管配以不锈钢焊接管件,就可以用来输送弱酸性或是弱碱性的化工流体了。
304 stainless steel is the most commonly used flange for manufacturing flanges. The flange made of this material will be at 20 degrees centigrade and is corroded in 10% nitric acid at less than 0.1 millimeters per year; the corrosion rate in 10% boiling acetic acid is less than 0.1 millimeters per year; the corrosion rate in 50% citric acid is less than 0.1 millimeters per year; 20% potassium hydroxide is corroded less than 0.1 mm a year. The corrosion rate of 80% phosphoric acid at 60 C is less than 0.1 mm per year, but the corrosion rate of 2% sulphuric acid is 50 millimeters per year at 50 C. So the stainless steel tube, which is welded by the inner lining of the cold rolled stainless steel belt, is fitted with a stainless steel welded pipe, which can be used to transport weak acid or weakly alkaline chemical fluids.
不锈钢法兰在制作经常是在有粉尘的场地进行的,这些粉尘它们会不断地落在设备表面。这些是可以用水或碱性溶液去除掉的。但对于有附着力的尘垢需要使用高压水或蒸汽进行清理。然后是浮铁粉或嵌入的铁的问题。在任何表面上,游离铁都会生锈并使不锈钢法兰产生腐蚀。所以必须清除。浮粉一般可随粉尘一起清除掉,如果粘着力很强的话,就必须按嵌入的铁来处理。
Stainless steel flanges are often produced in dusty grounds, which are constantly falling on the surface of the equipment. These can be removed by water or alkaline solution. However, the dust and dust with adhesion need to be cleaned by high pressure water or steam. Then the problem of floating iron powder or embedded iron. On any surface, free iron will rust and corrode stainless steel flanges. So it must be cleared up. Floating powder can usually be removed with dust. If adhesion is strong, it must be treated with embedded iron.
