Product Details

A flexible connector fabricated of natural or synthetic elastomers and fabrics and if necessary metallic reinforcements to provide stress relief in piping systems due to thermal and mechanical vibration and movement. Performance features include flexibility and concurrent movements in either single or multiple type construction, isolation of vibration and noise resistance to abrasion and chemical erosion.

 

Structure Detail

Tube
Lined with synthetic or natural rubbers to prevent leakage. Manufactured seamless from the inside to the end of a flange. Prevents holes in the body or weakening of fabric. These tubes can be designed to cover service conditions for chemical petroleum, sewage, gaseous and abrasive materials.

Cover
Outer surface composed of synthetic or natural rubbers protects the frame from damage or severe conditions. Special polymer is resistant to oil, sunlight, acid fumes and ozone and it is additionally coated to protect the exterior surface.

Carcass
Consist of fabric or metal reinforcement.
Fabric reinforcement :maintains tube and cover being flexible. Made of fine quality synthetic fabric but natural fabric used within acceptable temperature and pressure conditions. All fabric piles are impregnated with rubber or synthetic compounds to permit flexibility between fabric piles.
Metal reinforcement : wire or solid steel rings maintain the rigidity of the joint being inserted into the body. It extends the operational pressure range and ensures the product’s rigidity in vacuum service.
