Enhanced the mechanical properties of the outer sleeve.

2.Reduced the wall thickness of the outer sleeve.

3.Reduced the water absorption rate of the thermal insulation layer.

4.Increased the closed cell rate of the insulation layer.

5. Reduced the axis eccentricity of the insulation pipe.

6.Enhanced the uniformity of the overall pipe insulation density.

7. Increased the compressive strength of the insulation layer.

8. Reduce the thermal conductivity of the insulation layer, minimizing energy loss.
