ARCADE / ELAFLEX / DILATOFLEX RUBBER EXPANSION JOINTS

Swivel flanges

Full face flanges

Multi arches

Elaflex ERV

Our rubber ARCADE and ELAFLEX expansion joints with rotating flanges are our top of the range products, able to answer all your most demanding applications.

This type of expansion joint is ideal for:
- misalignment
- vibration
- expansion
- absorption of shock and noise
- reducing turbulence and fluid retention

We stock this standard expansion joint in EPDM and Nitrile. Also available on request in any size and length from DN32 to DN5000, it is equipped with stabilizing steel flanges PN10, PN16 or ASA, stainless steel 304L or 316L.

Rubber expansion joint with 3 arches and over are manufacture to be integrated in process where axial or lateral movements are wide.

The ARCADE multiple arches rubber expansion joint can be full face for better resistance to movement and vacuum. They can be stabilized and equipped with tie rods. With adequate rubber, they will be suitable for any type of medium and application. These expansion joints are a first choice solution.

To complete the range of Premium expansion joints, we propose full face rubber expansion joints. These expansion joints are manufacture with the best rubber on the market. Their construction resists almost full vacuum and high forces tension. 
​
Features
- reinforced by rings embedded in the mass and layers of polyester mesh
- Superior durability and reliability: the quality of the chosen materials and the customized manufacturing guarantee a greater longevity
- Wide variety of elastomers: Natural rubber, Neoprene, Nitrile, Butyl, EPDM, CSM (Hypalon). In special material: food, flame resistant, Viton and PTFE.
- Fiber and metal reinforcement: polyester, nylon, Kevlar or Nomex. For metal reinforcements, they can be cast in the mass or be in support for the suction for example with a vacuum ring in UB6, stainless steel 304, stainless steel 316 ...
- steel flange: flanges or segments

HVAC AND WATER expansion joint

There are many processes where the conditions of service are just basics. In such situations, simple molded expansion joints at reduced prices are sufficient.
Kenovel stocks EPDM compensators for water and weak acids, Nitrile for hydrocarbons and Hypalon for strong acids at very attractive prices. The construction lengths including flanges are 130, 150 or 200mm or style10 dimension (see table).
They are intended for simple and moderately demanding applications. Such as HVAC, hot water, iced water, glycol water, hydrocarbons, chemicals etc. These low cost expansion joints hold up to 16 bar at 20° C or 90° C with 2 bar pressure, and all  linear combinations of temperature and pressure between these two datas.
Our expansion joints are reinforced with a pressure-resistant frame and rotating steel flanges following PN10, PN16 or ASA 150. They have excellent ability to absorb vibration and noise, as well as corrosion. Their burst pressure is 60 bar up to DN300.

HVAC AND WATER double arches

In addition, to complete the range of economic solution, we extended our stock with double arches expansion joints. With 2 convolutions, a longer but standard overall length and an optional reinforcement ring, they reach considerable movements in all directions : axial, radial and angular. 
They offer a low cost solution for all your classical situation. However they don't compromise with low quality, but are actually manufacture with strict compliance to high standards. 

Full face expansion joint

To complete the range of low cost expansion joints, we stock full face rubber expansion joints. These expansion joints are manufacture with the rubber covering the face of the flange. Even though the flanges are fix, their construction better resist to vacuum and application where the forces could pull out the rubber outside floating flanges.
