A) Shock absorption expansion joint ; B) Easy installment and keep up ; C) Resistant to high temperature , pressure .
1. This product can greatly reduce vibration and noise pipeline system but can not solve all kinds of pipe interface displacement, degree of axial stretching problems. 2. The material can be made according to different acid, alkali, corrosion, oil, heat and other kinds of species to adapt to various of media and the environment. 3. Material is a polar rubber, sealing, light weight, easy installation and maintenance, long life, but to avoid contact with sharp metal instruments, so as not to puncture the sphere. 4. Without spporting bracket should use flexible stent, installation bolt tightened to use the diagonal method. 5. Such as the pipeline pressure is too high, the application of limit bolts to both ends of the flange together. 6. Flange connection standard adopt GB4216.3-4216.5 standard, as to other standards, can be explain. Level of the product working pressure 0.6MPa, 1.0MPa, 1.6MPa, 2.5MPa.
