Metal Expansion Joints Macoga

Macoga is Spanish manufacturer provide elastomeric or rubber expansion joint, metallic expansion joint to oil and gas, refinery, petrochemical, chemical, power, pulse and paper, food,…etc. industrial. Its application for cryogenic to high temperature service such as LNG, boiler, gas turbine, FCCU,….etc

The basic advantages to be gained from using Expansion Joints are:

  • Little space required for installation
  • Absorption of movements in multiple directions due to their inherent flexibility
  • They require no maintenance
  • They reduce load and temperature loss to a minimum

There are three basic movements that can be absorb by an Expansion Joint:

Axial Movement

Axial movement is the change in dimensional length of the bellows from its free length in a direction parallel to its longitudinal axis.

Angular Movement

Angular movement is the rotational displacement of the logitudinal axis of the bellows to ward a point of rotation

Lateral Movement

Lateral movement is the relative displacemnent of on end of the bellows to the other end in a direction perpendicular to its longitudinal axis.
