Rubber expansion joints
Our product line includes rubber expansion joints in sizes from 25 to 3800 mm, with standard or customized shapes and flanges
What is a rubber expansion joint?
A rubber expansion joint is a flexible connector manufactured with natural or synthetic fabrics and elastomers. They can also be manufactured with metallic reinforcements to relief the stress from the piping system caused by vibrations and/or thermal and mechanical movements.
The installation of a rubber expansion joint allows to compensate piping system movements, protecting them from stress caused by expansions, ensuring proficiency and cost savings in production phases.
Performance characteristics include flexibility and simultaneous movements in single or multiple arch construction, vibration isolation, and resistance to noise from abrasion and chemical erosion.
Definition
made of natural or synthetic fabrics and elastomers. A version with metallic reinforcements is also available to relief the stress from the piping system caused by vibrations and/or thermal and mechanical movements.
Manufacturing details
Made of natural or synthetic rubber without seems, which extends all the expansion joint’s length to the outer edge of its flanges. Its characteristic is to eliminate the possibility of fluid penetrating the carcass and weakening its structure.
Systems in which rubber expansion joints are used
The rubber expansion joints, designed, and manufactured by BBV Group, are used in all systems that convey pressurized fluids and/or operate under vacuum conditions at various temperatures:
- thermal power plants and refineries
- sewage treatment and water treatment and desalination plants
- paper mills
- chemical and metallurgical plants
- main and auxiliar generators in factories
- buildings and on-board ships
- air conditioning and heating and ventilation systems in commercial and public buildings, schools, apartments, shops, hospitals, hotels, and on-board ships.
