On a New Journey in Industrial Anti-Corrosion, Naflon Group Advances with Technological Strength

Naflon Group has successfully developed a large-diameter negative-pressure-resistant winding process pipeline, which will be applied in a domestic high-end fluorine new materials industrial park project. As a company dedicated to the research, development, and manufacturing of PTFE-lined valves and piping equipment, this achievement not only demonstrates our strong technical capabilities but also reflects our solid commitment to promoting industrial upgrading.

Excellent High-Temperature Resistance
By introducing a special metal mesh structure into the PTFE layer and combining them through a winding process, the thermal expansion and contraction of the PTFE layer are synchronized with the steel shell. This structure also enhances strength, improving both positive and negative pressure resistance. The product can withstand long-term alternating high and low temperatures, significantly extending its service life.

Outstanding Negative-Pressure Resistance
A special integrated steel-lined winding support structure is used, where the wound PTFE support greatly enhances the negative-pressure resistance of the PTFE layer. The product can operate under full vacuum (FV) conditions at 180 °C. Through the combination of a metal mesh and PTFE winding process, together with the wound PTFE support, it effectively addresses the demanding conditions of full vacuum operation at high temperatures.

Large-Diameter 3D Simulation and Structural Optimization
Using three-dimensional simulation and real-time vacuum testing, the structural design has been optimized to solve the challenges of excessive internal stress in large-diameter PTFE-lined pipelines, ensuring consistent product performance at an advanced industry level.

With a professional R&D team and a comprehensive quality assurance system, Naflon Group strictly adheres to standardized procedures throughout the entire process of material selection and process control, ensuring the high reliability of product performance. The successful development and application of the large-diameter negative-pressure-resistant winding process pipeline strongly demonstrate the company’s technological innovation capabilities. Upholding the corporate spirit of “Commitment to Anti-Corrosion and Pursuit of Innovation,” we are dedicated to providing customers with superior products and solutions. We sincerely invite partners from all sectors to engage in communication and cooperation for mutual growth and shared success.
