Detailed description of rubber flexible joints:
 
1- have superior capability in resistance of acid, alkali, oil, and electrolytic
2- become one of the alternatives of stainless steel and been successfully installed in tough work condition
3- suitable madia: chemical/petrochemical, marine, power generation, pulp/paper, steel mills and sater/wastewater treatment.
4-sturctuer: less length, the supply range is from 25mm to 3000mm 
5-pressure can be 1.0MPa/1.6MPa/2.5MPa, which is always used where low cost or space limitation control.
