AI Technical Summary
The insulation layer in existing electrically heated insulated pipes is not well-adhered to the inner layer due to thermal expansion and contraction, which affects the insulation performance.
By setting an insulation layer positioning structure layer on the outer wall of the insulation layer, including components such as sleeves, long bolts, horizontal plates and wear-resistant metal blocks, the insulation layer is squeezed to fit tightly against the outer wall of the heating structure layer, increasing the fit, and is protected by an outer sheath.
This improved the adhesion between the insulation layer and the heating structure layer, reduced heat loss, ensured insulation performance, and enhanced the aesthetics of the device.
