AI Technical Summary

Technical Problem

Existing cold-insulated pipe supports have poor stability at low temperatures, and layered cold-insulated materials are prone to axial relative displacement, while polyurethane foam in encapsulated cold-insulated materials has insufficient fire resistance.

Method used

The insulation layer is covered with cylindrical foam glass blocks, combined with axial limiting plates and buffer strips to enhance the integrity and fire resistance of the insulation layer. This avoids the limiting structure being embedded inside the insulation layer. The high fire resistance and low temperature stability of foam glass are utilized, and the stability is improved by combining buffer layers and moisture-proof layers.

Benefits of technology

It improves the stability of cold-insulated pipe supports at low and high temperatures, prevents temperature conduction, enhances cold insulation and fire resistance, and avoids material brittleness.

Abstract

The utility model provides a fireproof cold insulation pipeline support for fixing pipeline, and the cold insulation pipeline support comprises a saddle and a fixing mechanism arranged on the saddle, the saddle is used for adapting the fixing mechanism to be arranged on the base, the fixing mechanism comprises a pipe clamp, a protective layer, a moisture-proof layer and a cold insulation layer which are arranged from outside to inside along the radial direction of the pipeline, the cold insulation layer is formed by coating at least one circular tubular foam glass block on the outside of the pipeline, the end of the pipe clamp is provided with a first axial limiting plate, the first axial limiting plate radiates inwardly along the radial direction perpendicular to the axial direction of the pipeline from the end of the pipe clamp so as to resist the outer edge area of the end surface of the cold insulation layer, according to the utility model, the stability of the cold insulation layer along the axial direction of the pipeline is ensured, the fire resistance of the cold insulation pipeline support is improved, and the problem of brittle fracture caused by the slot embedding of the foam glass due to the brittle characteristic is avoided.
