FAQ
A1: QPQ treatment significantly improves the surface hardness and corrosion resistance of stainless steel, extends the service life of the rotary joint, and makes it more adaptable to harsh working environments containing moisture and oil.
A2: No. This series is specially designed for low-speed rotation or low-frequency oscillation under working conditions. High-speed operation will affect the sealing performance and service life of the product. It is recommended to select the corresponding high-speed model according to actual working conditions.
