Description

Rigid Reinforced Pipe

technical field

The utility model relates to the technical field of pipeline structures, in particular to a rigid reinforced pipeline.

Background technique

Common pipes in life are mainly used to transmit fluid substances. At present, due to various factors, most pipes are made of metal, plastic or composite materials.

It is clear to those skilled in the art that pipelines used in different occasions often have different requirements for pipelines. For example, pipelines used in drainage occasions mainly require anti-corrosion, and at the same time have enough rigidity to withstand the load of vehicles on the ground. For pipes used in water supply occasions, the pipes are required to have sufficient resistance to external pressure. Since they are pressure pipes, the rigidity of the pipes is usually not considered due to the existence of internal pressure. However, there are often occasions in engineering practice, such as the application of trenchless pipes, in addition to a certain flexibility of the pipe, it also needs to have a certain rigidity, and plastic pipes and plastic composite pipes often perform unsatisfactorily in terms of rigidity. It needs to have some rigidity while retaining flexibility.
