Rubber expansion Joints:

Intermech Rubber Expansion joints are designed to compensate axial, lateral or angular displacements and vibrations in piping systems or in equipment which operate at several conditions of pressure and temperature.

Being composed of a rubber body and not welded carbon steel ends connections, these joints become an excellent solution to compensate for thermal and/or mechanical displacements with low spring forces.

Bodies may be manufactured of different rubbers in order to satisfy the most important applicative necessities; including for certain specific situations, internal linings.

Bodies are internally reinforced with synthetic material cloth and metal rings to assure a high mechanical resistance while operating at a positive internal pressure or vacuum.

Intermech Rubber Expansion Joints are supplied from ND 1.1/4" (32mm) up to ND 80" (200mm), being recommended to operate up to 225 PSIG (16 Kgf/cm) and 250 °F (120°C), according to the specific model. For different models and other diameters, pressure and/or temperatures, please contact INTERMECH.

Features:

• Compensation for displacements with small installation lengths and low spring forces.
• Corrosion resistant.
• High absorption of mechanical and sonorous vibration.
• Low weight.
• Exempt of sealing joints.
• Not-welded end connections.
• Electrical discontinuity.
• Excellent ability to resist heat, water, weather and severe atmospheric conditions.

Applications:

• Air-condition systems.
• Pumps, air compressors, blowers, etc.
• Industrial piping systems.
• Marine piping systems.
• Sanitary systems.
• Any piping system where it is necessary to compensate thermal displacements.

Pressure / Temperature:

The allowable operating pressure (P) shown on dimensional table, correspond to temperatures up to 250°F (120°C). Find below the vibration of pressure resistance according to the operating temperature, the test pressures and the minimum burst pressures of the INTERMECH Rubber Expansion Joints.
