The quality of the drainage water conveying device is guaranteed. The zolhwSr water conveying device is used in the pipeline where no displacement is allowed. In addition to bearing the load, the fixed support must also bear the thrust and moment of various thermal displacements of the pipeline. This is a structure that requires the fixed support to have sufficient strength and rigidity. The rooting part of the fixing bracket should be firm and reliable. The fixing bracket is designed to compensate for thermal expansion of the pipeline. It is a good product. It is the location where the internal pressure and external force of the pipeline generate stacking stress. In the installation, the non-fixed and The non-fixed bracket is fixed by steam directly buried steel sleeve steel insulation pipe. It is composed of steel pipe for transporting medium, anti-corrosion jacket steel pipe, and ultra-fine glass wool filled between steel pipe and jacket steel pipe. Graphite and silicon calcium tile shell can also be used And filled with polyurethane foam compound.
