Pipe material is a necessary material for building engineering, commonly used in water supply pipes, drainage pipes, gas pipes, heating pipes, wire conduits, rainwater pipes, etc. With the development of science and technology, new material building materials gradually enter the building market, and the pipe material used for home decoration has experienced the development process from ordinary cast iron pipe to cement pipe, reinforced concrete pipe, asbestos cement pipe, nodular cast iron pipe, galvanized steel pipe, plastic pipe and aluminum plastic composite pipe. With the development of society, the use rate of building pipes is getting higher and higher, and various pipes are also needed in building construction.

[0003] At present, in the process of building pipe production, the compression resistance of the corresponding pipe material needs to be tested and processed, especially the pipe material of new material and composite material. At present, the compression resistance of the pipe material is detected by applying extrusion force to the middle end of the pipe material and observing the deformation of the pipe material. However, in the actual detection process, the deformation of the building pipe of composite new material under the same pressure is related to the pressure time, so there will be a deviation in the deformation test data caused by different pressures, and the space position of the supporting mechanism and the extrusion mechanism needs to be adjusted according to the pipe material of different lengths, which leads to low detection efficiency and certain limitations.
