Factors affecting the life of 304 stainless steel pipe
Generally speaking, there are the following points:
1, poor use environment;
304 stainless steel pipe itself has the ability to resist atmospheric oxidation, but also has the ability to corrode in the medium containing acid, alkali and salt. However, the size of its corrosion resistance is changed with the chemical composition of the steel itself, the mixing state, the use conditions and the type of environmental media. In the dry and clean atmosphere, there is absolutely excellent corrosion resistance, but if it is moved to the seaside area, in the sea fog containing a lot of salt, it will soon rust, affecting the service life of 304 stainless steel pipe.
PS: Users in high-pollution areas: such as the seaside, chemical plants, brick factories, electroplating pickling plants, waterworks, sewage treatment plants and other places to use 304 stainless steel pipes, or with corrosive chemical products to clean 304 stainless steel pipes, will cause rust, I hope to keep in mind.
2. Improper processing and installation; When the stainless steel processor is doing the product, when cutting the stainless steel pipe or iron, the iron filings will splash onto the surface of the steel pipe, and if it is not cleaned up in time, it will cause the 304 stainless steel pipe to rust. Installing stainless steel before painting walls or houses can also cause rust in stainless steel products.
3, improper cleaning and maintenance
In the cleaning process can not use the steel ball or steel wire brush to remove water stains on the surface of the stainless steel pipe, because this causes scratches on the surface of the 304 stainless steel pipe, in addition to avoid the use of bleaching ingredients and abrasive detergent, including detergent containing acid and alkali properties of the detergent, and then rinse the surface of the 304 stainless steel pipe with water at the end.
304 stainless steel pipe is an environmentally friendly material, the correct use and maintenance can make the service life extended. The premise is that the quality of the 304 stainless steel pipe you choose should be guaranteed, and choose a quality guaranteed 304 stainless steel pipe brand jblsteel.
