1. The sealing system has excellent physical properties and corrosion resistance and has a special form of three layers of sealing folds between the main devices, to ensure the tightness of the steel pipeline.
2. The rubber inner ring type has special elasticity, which can overcome the axial and radial displacement without affecting the basic sealing performance of the steel pipeline.
3. The sealing system achieves radial tension by fixing stainless steel expansion rings to achieve the sealing function. These fixed stainless steel expansion rings are installed by hydraulic machinery without the use of robots or chemical adhesives.
4. The sealing device can not only be used to repair the steel pipeline but also can be used as a steel pipe joint sealing matching device to improve the overall steel pipeline quality and performance for new steel pipeline systems.
