Distortion: at the construction site, due to the limitations of construction site, space and construction tools, the construction personnel will use the plasticity of stainless steel pipe instead of forced construction according to the construction specifications. Therefore, it is necessary to consider the distortion factors at the connection between pipe and pipe fittings.
Good corrosion resistance: a thin protective film will be formed on the surface of the stainless steel pipe, although the protective film is about 3 × 10-6mm, but it is very strong and tough. Even if it is damaged, as long as there is oxygen nearby, it can be regenerated immediately to prevent rust. As long as the characteristics of stainless steel are known and used correctly, there is no need to worry about rust under less corrosive conditions such as water pipes or hot water up to 100 ℃, nor about the reduction of inner diameter or increase of resistance caused by common "rust protrusions" in galvanized steel pipes, It can obtain water flow that will not be blocked.
Due to its light weight, it can be easily handled and constructed and reduce costs. 304 stainless steel pipe only needs about one third of the thickness of galvanized steel pipe due to its excellent corrosion resistance and mechanical properties. Therefore, the weight of the pipe is greatly reduced, and the cost is also reduced, making the handling easier and the installation more convenient.
For stainless steel pipe rust removal, the surface of steel shall be cleaned with solvent and emulsion first. This method is only used as an auxiliary means of anti-corrosion and can not really remove the rust of stainless steel pipe.
You can also use steel brush, wire ball and other tools to remove the loose scale and rust on the surface before cleaning, but in this way, if you still do not take good protective measures, it will be eroded again.
