Among stainless steel pipe suppliers, stainless steel seamless pipes are generally used outdoors. The outdoor environment is still relatively bad. For the bad environment, it will seriously affect the work of stainless steel seamless pipes. The common factors are oxidation and corrosion, etc. we should do a good job in maintenance, Now let's talk about the outdoor maintenance of stainless steel seamless pipe?

The products of Square Stainless Steel Seamless Pipe after pickling and passivation shall be subject to the corresponding salt spray test. The designed outdoor cabinet is generally required to have no obvious White Embroidery in 30 day salt spray test (if yellow rust and red rust appear, it is absolutely unqualified). The specific product depends on your product specification. In addition, electrostatic powder spraying coating is also a feasible way, which is much better than ordinary painting. Good powder has quite good weather resistance and better adhesion than painting, but its process requirements are very high, and the phosphating before treatment must be strictly in place. Moreover, the ability to resist unnatural factors is poor (if man-made damage), and it is not suitable for occasions with a large amount of liquid.

For the interface part or the part with welding, its flatness shall be maintained as far as possible, otherwise it will have a great impact on the performance of surface treatment. If it is rough, it can be polished properly.

In the production process, some stainless steel seamless pipes need to be placed outdoors. Stainless steel should be pickled and passivated in the whole area after processing. Due to many impurities in domestic stainless steel, it is easy to have redundant reaction during pickling and passivation, resulting in discoloration or uneven protection. Imported stainless steel is much better.

The above is the description of outdoor maintenance of stainless seamless pipe.
