According to industry data, 80% of early failures of PFA branch ports are caused by improper installation processes. Relying on 32 years of R&D and manufacturing experience in fluorine material lining equipment, Jiangsu RANA has established a full-process refined installation process and quality control system from pre-treatment to final inspection, ensuring perfect adaptation between PFA single-flange branch ports and fluorine-lined equipment, and maximizing service life. Jiangsu Rana Fluorine Material Technology Co., Ltd.
The technical team of Jiangsu RANA explains the four core installation process points in detail:
1. Equipment opening pre-treatment: The opening of the container must be polished smooth without burrs, and the opening diameter should be 0.5~1mm larger than the outer diameter of the branch port sleeve. This avoids deformation of the flange surface caused by forced assembly, laying a foundation for subsequent welding and sealing. Jiangsu Rana Fluorine Material Technology Co., Ltd.
2. Lining welding process: As the core key process, the back of the branch port flange and the PFA/PTFE lining layer on the inner wall of the container must be welded by hot air welding. The welding temperature should be strictly controlled at 320℃~350℃, and the weld width should be no less than 10mm, ensuring that the connection is completely fused into one without gaps or leakage channels. Jiangsu Rana Fluorine Material Technology Co., Ltd.
3. Flange sealing assembly: When the external pipeline flange is docked with the branch port flange, PFA coated gaskets or pure PFA gaskets are preferred. The locking torque should be strictly implemented in accordance with standards to prevent the branch port flange from cracking due to excessive torque, and ensure long-term stable sealing of the sealing surface.

4. Dual quality inspection: After installation is completed, a 5kV/mm spark leak detection is first carried out to check for pinhole defects in the lining layer; then a hydraulic pressure test with 1.5 times the working pressure is carried out, with a pressure holding time of 30 minutes without pressure drop or leakage. The equipment can be put into use only after passing both inspections. Jiangsu Rana Fluorine Material Technology Co., Ltd.
As a leading enterprise in domestic fluorine material lining equipment, Jiangsu RANA has an industry-leading 10,000-level clean workshop, and a professional technical team provides full-process installation guidance and technical training. It avoids installation risks from the process source, and provides integrated solutions of "product + process + service" for customers in semiconductor, chemical, new energy and other fields.
