MACOGA Expansion Joints are designed, manufactured and tested in accordance with:

  • E.J.M.A. (Expansion Joint Manufacturers Association, Inc.)
  • ASME VIII, Div. I, App. 26
  • EN 14917, European Standard for Metal Expansion Joints.

MACOGA Expansion Joints are of two categories

  • Metal Expansion Joints
  • Rubber Expansion Joints

Metal expansion joints

An expansion joint is a device primarily formed by flexible bellows used to absorb movements in a piping system while containing pressure and a medium running through it.

MACOGA uses different methods for producing the bellows depending upon a range of different contributing factors (eg. diameters, the number of sheets used, the materials used, etc.), although in all cases the bellows are manufactured using seamless tubes or metal cylinders welded along their length. The methods used are as follows: Expanding, Elastomeric, Hydraulic and Roll forming.

Our manufacturing range includes Circular Expansion Joints of the following types:

  • Axial
  • Hinged
  • Gimbal
  • Lateral
  • Pressure Balanced
  • Jacketed
  • Externally Pressurized
as well as Rectangular Expansion Joints which, with limitless dimensions, can be supplied with different convolution and corner types:
  • V-shaped – Camera Corner
  • V-shaped – Miter Corner (single or double)
  • U-shaped – Rounded Corner

Rubber expansion joints

Rubber Expansion Joint is flexible connector fabricated of natural or synthetic elastomers, fluoroplastics and fabrics and, if necessary, metallic reinforcements used to absorb movements in a piping system while containing pressure and a medium running through it. Our rubber expansion joints are designed according to the Pressure Equipment Directive PED 97/23/EC for the specified operating conditions and according to the FSA (Fluid Sealing Association) Non-Metallic Expansion Joints Division. MACOGA Rubber Expansion Joints are manufactured considering:
  • Chemical and Temperature resistance of internal layers
  • Pressure-resistant reinforcing fabrics
  • Weather, ozone and UV-resistance of external layers
