What are the production factors that affect the coating of seamless pipes

What are the key factors affecting the coating of seamless pipes?
C276 seamless pipe can be used in many places in natural environments because of the variable structure of the exterior design, which can consider the perspective that ordinary seamless pipes cannot complete, and has won everyone's recognition and favor. In the production process of C276 seamless pipe, in order to improve its performance indicators, its surface will be coated. During the production process, the following four factors often affect the coating of C276 seamless pipes. Let's take a look!
During the entire process of stainless steel passivation, seamless pipes will produce suppressed metastable structures. Once in a geographical environment, it can cause chemical changes. Therefore, harmful substances attached to the surface of seamless pipes should be removed before painting;
2. Potassium thiocyanate will seriously affect the coating of C276 seamless pipe, so the composition of Potassium thiocyanate should be strictly controlled during the whole passivation process, and the structure of C276 seamless pipe will be damaged if it exceeds the standard. Generally, pharmaceutical factories will limit the amount of Potassium thiocyanate and carry out the next practical operation according to the relative preparation to ensure the coating of seamless pipes;
The moisture content in C276 seamless pipe is relatively low, and the passivation characteristics of stainless steel are relatively low, which will have a certain degree of impact throughout the entire coating process. In order to achieve better practical coating effects, it is necessary to improve its essential influencing factors.
As is well known, the surface of seamless pipes is relatively smooth. This is because the smoother the surface, the less likely it is to get dirty. During the manufacturing process, seamless pipes will be polished and coated. In the actual manufacturing process, the corrosion resistance of seamless pipes should be improved.
