Functions of stainless steel industrial pipes

Functions of stainless steel industrial pipes

The corrosion resistance of stainless steel industrial pipes depends on the alloying elements contained in the steel. Chromium is the fundamental element that makes stainless steel pipes corrosion resistant. When the chromium content in the steel reaches about 12, the chromium and the oxygen in the corrosive medium form a very thin oxide film (self-passivation film) on the surface of the steel. , Can prevent further corrosion of the steel matrix. In addition to chromium, the commonly used alloying elements of stainless steel industrial pipes include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of various uses for the arrangement and function of stainless steel pipes.

Everyone must carry out regular cleaning and maintenance on the surface of stainless steel industrial pipes. When cleaning the surface of the stainless steel industrial pipe, be sure to pay attention not to cause surface scratches. It is not necessary to use wire brushes, special grinding tools, etc., to prevent the application of bleach ingredients and abrasive cleaning fluids, and clean the surface with clean water after cleaning. 　　不锈钢工业管是耐蚀性比较好的钢材牌号，因此很多化工企业和水上船舶的不锈钢管大部分都是采用不锈钢工业管，较起其的不锈钢工业管能够省许多保养层面的时间。　　看过上边的內容，坚信大家都早已了解不锈钢工业管的表面清理保养。

Method for treating the surface of sanitary stainless steel pipe

Method for treating the surface of sanitary stainless steel pipe

The research institute verified that the life of the anti-corrosion layer depends on the type of coating, coating quality and construction environment. The surface treatment of the sanitary seamless pipe has an impact on the life of the anti-corrosion layer about 50%. Therefore, it should be strictly in accordance with The anti-corrosion coating specification has continuously explored and summarized the surface requirements of sanitary stainless steel pipes, and continuously improved the surface treatment methods of sanitary stainless steel pipes.
