Belman A/S Expansion Joints and Bellows

Belman is an experienced provider of high-quality expansion joint solutions. The company is repeatedly chosen by clients worldwide for compensators, steel expansion joints, expansion bellows, metal expansion joints and steel bellows.

The company is chosen by customers worldwide for its high-quality, short delivery times, flexibility, responsiveness, customised solutions, experience, assured quality solutions and commitment.

Belman is part of the Belman Group, which consists of Belman A/S in Denmark, Cardwell Limited in the UK, and OOO Belman Russia in Russia.

Steel compensators to absorb axial, lateral and angular movements

Belman has a standard expansion joint programme from DN40 up to DN6,000 (DN12,000 in certain segments), with a gauge pressure capacity up to 150barG. These flexible connections can absorb axial, lateral and angular movements. Depending on the type of compensator chosen, these movements can be absorbed in combination.

Standard solutions include:

  • Gimbal expansion joints
  • Hinged expansion joints
  • Angular expansion joints
  • Lateral expansion joints
  • Exhaust compensators

The company also provides a wide range of tailored solutions for specific customer requirements.

Customised expansion joint solutions

Customised solutions are one of Belman’s core strengths and this has resulted in the company being the preferred provider of expansion joint solutions, including:

  • Pressure-balanced expansion joints
  • Crossover bellows
  • Corner relief expansion joints
  • Rectangular compensators
  • High-pressure pump connectors
  • Externally pressurised expansion joints
  • FCCU expansion joints
  • Rectangular expansion joints (both 45° and 90° mitred corners, camera and radius corners)
  • Bellows with tantal or PTFE-lining

Belman supplies steel expansion joints that are calculated and designed according to several different design codes, including EN 13445, EN 13480, EN 14917, ASME VII, Div. I, ASME B31.3, ASME B31.1 and AD 2000 or EJMA.

All solutions can be supplied CE-marked in compliance with the pressure equipment directive 97/23/EC.

CAD drawings, 3D illustrations, finite element analysis and technical consulting can also be provided during the development of special solutions.
