If the diesel tank is insulated from the outside, is it necessary to apply a topcoat to the inner tank walls?
Thread Content
The diesel tank design institute has provided insulation, and before applying the insulation, paint has been applied to the bottom as well as the two sides and two middle sections. I would like to ask: is this necessary?
Based on what standards? What’s the main reason?
Construct in accordance with the diagram. There’s no reason.
If a storage tank that requires insulation is involved, corrosion protection of the metal surface must be carried out before applying the insulation. It is mainly to prevent electrochemical corrosion of the insulation layer when it becomes damp. However, if 5 coats are applied to achieve a thickness of over 200 microns, it is somewhat over-protective. It is recommended to apply 3 coats of paint; 1 base coat, 1 intermediate coat, and 1 top coat will yield the best results. This ensures construction quality, with thorough inspections; there are 3 colors available for the paint, and the thickness is guaranteed. It should be emphasized here that the corners at the bottom of the tank in the insulation layer need to have enhanced anti-corrosion protection.
Thank you, I’ll add you on WeChat to discuss when we have time
