To ensure the excellent performance of PE-RT pipes, the selection of high-quality PE-RT raw materials, selection of efficient equipment and production processes, and standardized and effective product quality control are indispensable.
First, select high-quality PE-RT raw materials
PE-RT raw materials are the basis for guaranteeing the quality of PE-RT pipes. Only the selection of real PE-RT raw materials can meet its needs for heat resistance and long-term hydrostatic pressure.
Second, choose reasonable equipment and production technology.
1. The specially designed screw and extrusion process can ensure that the properties of the raw materials are well transferred to the pipe.
2. According to the characteristics of PE-RT raw materials, special molds and cooling systems are used.
The viscosity of PE-RT molten material is relatively large. If the mold and cooling system are not designed properly, it is easy to cause the molten material to stick to the die and sizing sleeve during high-speed production, which will cause unstable production and uneven product dimensions. Easy to leave quality risks.
3. Implement online monitoring and control.
Generally, the dimensional fluctuations of PE-RT coils in the production process are not easily found. In this regard, on the one hand, the stable performance of pipe production dimensions is ensured by means of reasonable screw and die design, extrusion process control and cooling setting control. On the other hand, laser calipers and other devices are used to monitor the outer diameter of the pipe in real time online to ensure that the dimensional change of the pipe can be monitored and adjusted in a timely manner without affecting the installation and use of the pipe. The establishment of an effective product quality control system is a guarantee.
