They represent toroid-shaped rubber-fabric cover arranged on metal case with end-to-end channel and branch pipe for attaching to rubber-fabric flexible pipe that is used for bypass of transported liquid or gas.
Encircling air pressure plugs are used when it is necessary to preserve pipeline functioning while repairing of its part.
Products have a certificate of the approved form. Instructions, log books, detailed description of assembling and dismantling procedures and safety requirements, storage and transportation guidelines, manufacturer's guarantees are provided alongside with the products.
