In the UHMWPE (Ultra-High Molecular Weight Polyethylene) pipeline system, flange connection is extremely widely used. The most prominent features of this connection method are its firm connection, good sealing performance, and ease of installation and disassembly. It can adapt to pipeline systems of different pressures and pipe diameters, playing a crucial role in the mining field.
I. Pipe Flanging Process
1. Preparation Work
Before flanging the pipeline, determine the specifications, models, and lengths of the UHMWPE pipes according to the design requirements and on - site conditions. Check that the pipe surface is free of cracks, scratches, deformation, etc. Then, fix the pipe on a professional flanging device, prepare the corresponding tools, and inspect the equipment to ensure its good performance and normal operation.
2. Heating the Pipe
Before heating the pipe, first slip the matching flange onto the pipe and adjust the position of the pipe to match it with the mold of the flanging machine. Then, heat the pipe to a temperature between 180 - 220°C and slowly move it close to the heating plate to ensure uniform heating.
3. Flanging Operation
Use the mold of the flanging machine to perform the flanging operation on the end of the heated pipe. Generally, the width of the flanging is controlled between 15 - 25mm. Apply pressure to the heated end to form a flat and smooth flange edge.
II. On - site Application
1. Industrial Applications
Flange - connected UHMWPE pipes are widely used in industrial fields such as chemical, mining, and power industries. UHMWPE pipes have good corrosion resistance and high wear resistance, making them an ideal choice for transporting materials such as ore pulp and tailings in the mining industry.
2. Installation Precautions
When performing flange connection of UHMWPE pipes on - site, the following points should be noted. First, strictly follow the design requirements and construction specifications to ensure the quality of the connection. Second, pay attention to the environmental conditions at the construction site and avoid installation in bad weather. At the same time, do a good job in on - site safety protection to prevent safety accidents. Finally, after the installation is completed, conduct pressure tests and leakage inspections on the pipeline system to ensure the sealing and reliability of the pipeline system.
