The company can produce various specifications of FRP sand-filled winding pipes and FRP winding process pipes with a diameter of 100-4000mm and a length of less than 18000mm. The working temperature of the pipeline is 40℃ -80℃, the pipeline with special ratio can withstand high temperature of 110℃, and the pipeline will not crack under the freezing medium. If used for large and medium flow pipelines, the construction cost of large-diameter quartz sand-filled pipelines is 30% lower than that of steel pipes of the same diameter, which is equivalent to cement pipes, and has convenient transportation, low construction costs, no maintenance, and a service life of 50 years above.
