Technical Field

The utility model relates to a conveyer pipe technical field specifically is a inside lining heat preservation cold water conveyer pipe.

Background

Need carry cold water among the present industrial production, need utilize the pipeline to carry cold water, when carrying cold water, liquid is in the contact of flow in-process and pipeline inner wall, and the pipeline outer wall directly exposes in the environment, and it is great to receive external environment to influence the cold loss, needs keep apart the heat preservation, avoids cold water to lose the great energy loss that causes of cold loss when carrying.

There is certain defect current heat preservation cold water conveying pipe when using, and current conveyer pipe sets up the heat preservation in the outside of pipeline, keeps warm through outside heat preservation, and heat retaining effect is relatively poor, and the inner wall of pipeline directly contacts with water in addition, causes the inside of pipeline to rust easily after long-time the use, influences the life of pipeline.

The applicant is applying the utility model discloses the time, through the retrieval, discovery chinese patent discloses a "heat retaining pipeline", and its application number is "202020608018.0", and this patent mainly sets up the heat preservation at pipeline body outer wall, sets up the cavity in the heat preservation, can utilize the air bed in the cavity to insulate against heat, is scalded by the pipeline when avoiding personnel to contact pipeline, the utility model discloses a set up the heat preservation in the inside of pipeline, paint tetrafluoroethylene on the surface of heat preservation, can surface water and the inner wall direct contact of steel pipe, the inner wall of surface steel pipe corrodes, has improved the life of steel pipe effectively.

Therefore, the utility model provides a inside lining heat preservation cold water transport pipe to solve above-mentioned problem.

SUMMERY OF THE UTILITY MODEL

The utility model provides a not enough to prior art, the utility model provides a inside lining heat preservation cold water transport pipe has solved above-mentioned problem.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a inside lining heat preservation cold water delivery pipe, includes the steel pipe body, the one end of steel pipe body is provided with the flange, one side of flange begins flutedly, the inner wall of steel pipe body is provided with first heat preservation and second heat preservation respectively, the one end of second heat preservation is passed the inside of steel pipe body and is extended to the inside of recess, and one side of second heat preservation is provided with the fillet.

Preferably, the inner wall of the steel pipe body is subjected to sand blasting for rust removal.

Preferably, the inner wall of the steel pipe body is alternately sprayed with glass fiber and epoxy resin.
