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。

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.

Share the calculation formula for the pressure of stainless steel pipes: The water pressure that stainless steel pipes can withstand is not the same as the pressure value of different materials; the outer diameter and wall thickness are also very important factors, the thicker the wall thickness, the pressure value that can be withstood The larger, for example, the same outer diameter, 10 thick stainless steel pipes can withstand much higher water pressure than 5 thick stainless steel pipes; in addition, it is also related to the outer diameter, the larger the outer diameter, the pressure that can be withstood The smaller, such as the same wall thickness, the larger the outer diameter, the smaller the pressure value it can withstand;
