Features
Shock absorption
Easy installment and keep up
Resistant to medium and temperature, pressure
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.
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.
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.
Without supporting bracket should use flexible stent, installation bolt tightened to use the diagonal method
Such as the pipeline pressure is too high, the application of limit bolts to both ends of the flange together
Flange connection standard adapt GB standard as to other standards, can be explain. Level of the product working pressure 0.1-6.0Mpa.
