Abstract
The invention relates to a U-PVC (unplasticized polyvinyl chloride) pipeline equipment thermal insulating outer protecting system which is formed by using a U-PVC sheet to wrap the outer wall of a pipeline around an axis of the pipeline and along the section extending direction of the pipeline. Sections of two winding edges, on the outer wall of the pipeline, of the U-PVC sheet are overlapped. The overlapped sections are connected through adhesives or nails. The U-PVC sheet can be cut on site according to straight length and diameter of the pipeline. U-PVC bending pipe sheets, U-PVC multi-pass sheets and U-PVC pipe-cap sheets are formed in advance by means of die pressing, and convenient to mount without on-site production. U-PVC is light, good in thermal insulation, flame-retardant, acid- and alkali-resistant, corrosion-resistant, and high in bending strength and impact toughness. Compared with traditional the outer protecting layers with metal in ordination with thermal insulating materials, the U-PVC (unplasticized polyvinyl chloride) pipeline equipment thermal insulating outer protecting system is convenient to machine and assemble, and low in application cost.
