Description

Technical Field

[0001] The utility model relates to a glass fiber reinforced plastic pipe sleeve joint, in particular to a glass fiber reinforced plastic sleeve joint for sewage transportation. Background Art

[0002] The FRP sleeve joint is a connector used to connect FRP pipes. FRP pipes are widely used and can be used as sewage pipes. However, the existing FRP pipe joints often leak due to the problem of connection sealing. Once a leak occurs, it will cause sewage leakage. Secondly, the connection between the existing FRP pipe sleeve and the FRP pipe is only connected by the friction between the sealing layer and the FRP pipe. After long-term use, the sleeve joint and the FRP pipe are easily separated, especially when the FRP pipe moves axially. Once separated, it will cause a large amount of sewage leakage. For this reason, a FRP sleeve joint for sewage transportation is proposed. Utility Model Content
