- Q: What is the difference between internal and external coating of steel pipes?
- The main difference between internal and external coating of steel pipes lies in the purpose and location of the coatings. The internal coating is applied on the inner surface of the steel pipe to protect it from corrosion and ensure smooth flow of the contents within the pipe. It is commonly used to prevent contamination of the transported liquid or gas and to extend the lifespan of the pipe. On the other hand, the external coating is applied on the outer surface of the steel pipe to protect it from environmental factors such as moisture, chemicals, and physical damage. It helps to prevent corrosion and maintain the structural integrity of the pipe, especially in harsh conditions. Overall, while the internal coating focuses on the functionality and preservation of the transported contents, the external coating primarily aims at safeguarding the pipe itself from external influences.
