What is the best material to use for tank insulation in hot water projects? How should I do insulation?

Hot water project, tank insulation materials currently on the market most of the polyurethane pressure template or polyurethane on-site foaming. Due to the polyurethane field foam insulation by climatic conditions, construction difficulties and other impacts, the current market are basically using polyurethane pressure template insulation. When using polyurethane pressure template insulation, polyurethane pressure template must maintain more than 40-50mm thickness.

Specific practices are:

1, welding and installation of insulated water tank liner;

2, polyurethane compression template insulation material assembly;

3, with filler will be polyurethane compression template gap cloth;

4, welding and installation of the tank outer layer of stainless steel;

5, and then to the outer stainless steel plate gaps in the insulation treatment.
