As I lead the development of economy, countries to develop the source industry, long distance oil and gas pipeline is an important means of energy security, in the process of oil (gas) pipeline anticorrosion construction of Q345D steel pipe corrosion protection is an important work of it is the precondition of anticorrosive layer and Q345D steel pipe can be firmly with, today will see the method of Q345D steel pipe anti-corrosion together with Katalor.
1. Solvent and emulsion are used to clean the Q345D steel pipe anti-corrosion surface to remove the oil, dust, lubricant and other similar organics. However, it can’t remove the rust, oxide skin and solder on the Q345D steel pipe surface.
2. Perform chemical pickling on the Q345D steel pipe to remove the oxide scale, old coating and rust.
3. Use tools to remove rust, mainly use steel wire Q345D steel pipe brush and other tools to polish the steel surface, which can remove loose or warped oxide skin, rust, welding slag, etc.
4. The spray derusting, mainly through the high power motor drive the blade high-speed rotation, make Q345D steel pipe grit, segment, minerals and other abrasive wire under the action of centrifugal force on Q345D steel pipe surface spray processing, this approach can effectively clear the rust, oxides and dirt, can achieve the required uniform roughness, is ideal way of cleaning.
Katalor has more uesful information about Q345D steel pipe. So if you have demand of Q345D steel pipe, please contact us freely. We can supply the Q345D steel pipe with high quality and different size.
