6. High-Purity Water Treatment: A stable-pressure, clean fluid distribution system for high-purity water delivery.

Advantages compared to other materials

1. Comparison with metals (stainless steel, aluminum alloy): Metals are susceptible to corrosion by acids and bases, and at high temperatures they readily oxidize, releasing metal ions that can contaminate high-purity media. PEEK Corrosion-resistant with no leaching and no rust, it is compatible with high-purity precision processes, weighs less, and carries no risk of corrosion.

2. Comparison PTFE Polytetrafluoroethylene: PTFE It has low strength and poor creep resistance, and is prone to deformation and collapse under high temperature and high pressure, leading to uneven flow distribution. PEEK High rigidity, dimensional stability, wear resistance, and aging resistance; service life is PTFE of the 3 – 5  倍, with no loss of accuracy over long-term use.

3. Compared with ordinary plastics ( PP 、 PVC ): Ordinary plastics have low temperature resistance, are prone to aging, and exhibit poor corrosion resistance, making them suitable only for normal-temperature, standard operating conditions. PEEK It can withstand extreme temperatures and pressures as well as highly corrosive environments, making it suitable for a wide range of high-end, demanding operating conditions.

Precautions for Use

1. Prior to assembly, remove debris and dust from the boreholes; for high-purity operating conditions, ultrasonic cleaning is mandatory to prevent particulate contamination.

2. Do not strike or crush the product with excessive force; when assembling threaded connections, strictly avoid over-tightening to prevent structural cracking and thread damage.

3. During installation under high-temperature conditions, thermal expansion gaps must be provided to prevent jamming, seizing, or deformation during equipment operation.

4. Do not use concentrated sulfuric acid or strongly oxidizing solvents for soaking and cleaning; for routine cleaning, wipe with deionized water or ethanol, or perform ultrasonic cleaning.

5. Store in a cool, dry place away from light and dust, and avoid prolonged exposure to ultraviolet radiation to prevent material degradation.
