M Barnwell Services offers a variety of different rubber expansion joints as well as accessories (UV protection panels / flange protection hoods, etc.) that are specifically engineered for the movements and vibrations in piping systems.

The Rubber Expansion Joint range will:

  • Enhance thermal stability
  • Relieve system strain because of thermal change, load stress, pumping surges, wear of settling
  • Compensate for misalignment
  • Eliminate electrolysis between dissimilar metals
  • Lower mechanical noise
  • Absorb movement and vibration

Applications within piping systems include Axial Movement, Lateral Movement, Angular Movement, Torsional Movement, and Vibrations / Oscillations / Noises.

Rubber Expansion Joints

All of our Rubber Expansion Joints carry safety ratings that exceed product specifications in areas such as pressure and movement. Non-metallic expansion joints and flexible couplings are ideally suited for a wide variety of industries including petrochemical, offshore drilling, water and gas, compressor pump and valve, food and manufacturing.

Types of Rubber Expansion Joints we offer:

PIPING EXPANSION JOINTS

Expansion joints for piping systems are flexible connectors, made out of PTFE, natural or synthetic elastomers, with combinations of rubber, fabric and metal reinforcement.

DUCTING & LOW PRESSURE EXPANSION JOINTS

Ducting and low pressure expansion joints are lightweight flexible connectors designed for gaseous media made out of natural or synthetic elastomers, with combinations of rubber and fabric reinforcement especially for scrubbers, precipitators, baghouses, and fans in air handling systems.

COMMON ACCESSORIES

Rubber expansion joint accessories include retaining rings, control units/tie rods, and metal flow liners.
