Abstract

The invention discloses a method, device and system for identifying defects for pipes. The method for identifying the defects for the pipes comprises the following steps of monitoring the radial sizeof a sintered pipe, and marking a defected pipe section corresponding to a radial dimension exceeding a first preset range value. The method ensures that a pipe diameter re-measuring is only aimed atdefected pipes, greatly reduces the workload of pipe diameter re-measuring, improves the speed and efficiency of the pipe diameter re-measuring, and thus improves the production efficiency and yield of the pipes of an enterprise. The method not only ensures the quality stability of the pipes, but also ensures the credibility and reputation of the enterprise, thereby being conducive to the good development of the enterprise. The method can also reduce the investment cost of re-measuring pipe diameter.

Description

technical field

[0001] The invention relates to the technical field of polymer material manufacturing, in particular to a defect identification method, device and system for pipes. Background technique

[0002] Due to the advantages of low density, light weight, high rigidity, good insulation, high strength, good colorability, and convenient molding, polymer materials make it more and more popular to replace steel with plastic and wood with plastic. In the prior art, transmission extrusion is the main production method of PTFE (polytetrafluoroethylene) pipes, and the equipment used is transmission extruder. At present, transmission extruder is divided into horizontal extruder and vertical extrusion. There are two types of extruders, and the transmission extruder is generally combined with a sintering furnace to form an extrusion unit.

[0003] The production process of the vertical PTFE pipe is as follows: the transmission extruder extrudes the PTFE raw pipe, passes through...
