How much paint is required per square meter on the outer surface of 20G DN89*4 steel pipes? The primer is made of epoxy paint, while the topcoat is made of perchloroethylene paint.
0.1 kg per square meter is fine, 1 kg is also fine; the person in charge can apply more coating if they want to, or less if they prefer, as long as no one checks the thickness of the coating.
Generally, it’s 0.3g per square meter, right? Anti-corrosion experts will provide an answer to this. Also, what does 20G refer to in the original post?
20G is a type of carbon steel.
General design documents have specific requirements, and calculations can be carried out in accordance with those requirements. Based on my calculations, with four coats of primer applied, 0.442 kg of paint is required per square meter for DN80 pipes using polyethylene primer.
