Bonna Pressure pipes have a proven efficiency for over 100 years with:

  • Sea outfalls.
  • Power station cooling water pipework.
  • Sewage pumping mains.
  • Sewage treatment works.
  • Industrial plant pipework.

Plus more recently, with drinking water pipelines including the unique ability to be used for jacking under roads, railways and business developments.

Benefits

Design Service

The requirements for each pressure pipe application are unique. A major advantage of the Bonna pressure pipe system is the inclusion of a free, in-house project design service which provides:

  • Design calculations.
  • Layout drawings.
  • Installation manuals.
  • Maintenance manuals.
  • Optional site supervision.

Durability

  • Will withstand full vacuum conditions.
  • High resistance to impact loading.
  • Abrasion resistant internal lining.
  • Low hydraulic coefficient of friction.
  • High resistance to floatation.
  • Resistant to external climatic conditions.
  • Designed to withstand water hammer.

Cost Effectiveness

  • Optimal design for each project.
  • Most ‘as dug’ material can be used as backfill.
  • Thrust blocks are not required for welded joints.
  • Cathodic protection is not required.
  • Pipeline curvature achievable through joint deflection.

Versatility

  • Unrivalled diameter range from DN 250 – 4000.
  • Installation by open cut or jacking.
  • Underwater installation by float and lower, bottom tow or jacking.
  • Joints can be welded, flanged, gasketed or custom made.
  • A wide range of factory produced fittings are available, to virtually any configuration.

Specification & Quality Assurance

All pipes and fittings are designed and manufactured to BS EN 639 and BS EN 641 and manufactured in accordance with a Third Party Certified Quality System complying with BS EN ISO 9001.

Standard Pipe Design

Pipes consist of three primary components:

  • A watertight steel cylinder core with end rings to suit various joint types.
  • An internal protective concrete lining.
  • An external, load bearing, reinforced concrete protective coating.

Some schemes have been supplied up to 24Bar pressure.

Fittings

  • Fittings of any configuration can be produced to suit the specific needs of each project.
  • Fittings are coated internally and externally with reinforced concrete for durability and load bearing strength.
  • Fittings include bends, tees, reducers, short length pipes, diffuser units, flanged adaptors, closure units and settlement compensator systems.
