- Is the inside of galvanised steel pipes also galvanised?
Generally, the inner wall of galvanised steel pipe does not need to be galvanised. Because the inner wall of the steel pipe is not as corrosion-resistant as the outer surface, but usually only by way of steel pipe design and welding process to ensure the integrity of its inner wall, so as to improve the corrosion resistance of the inner wall.
- Advantages and disadvantages of galvanising the inside of galvanised steel pipes
The advantage of galvanising the inner wall of galvanised steel pipe is that it can improve the corrosion resistance of the inner wall, thus improving the service life of the steel pipe. However, the disadvantage is that the cost is higher, and in the production process may appear uneven galvanisation of the inner wall of the steel pipe.
- Application areas of galvanising
Galvanisation is widely used in construction, manufacturing, transport and other fields. For example, in the construction field, galvanised steel pipe is usually used as water pipes, gas pipes and so on. In the manufacturing industry, it is commonly used in the production of refrigeration equipment, automotive parts and so on.
