Quality Control & Testing for Rubber Expansion Joints

Quality Control

Our Quality Control Department carefully monitors each of the different steps involved in the production process of our rubber expansion joints, right from the moment the raw materials are purchased up to the final controls and tests carried out on each Expansion Joint which come off our production line.

All the quality checks and tests are carried out are based on our Quality Control Manual, approved under ISO 9001, as well as our internal rigorous Quality Procedures.

All our Expansion Joints undergo a series of controls and tests at each of the different steps in the manufacturing process and before they leave the factory.

No product is shipped to the customer until its quality and conformance to customer specifications is assured.

The following tests are carried out if requested and/or if stipulated in the terms of a contract:

  • Hydraulic Pressure Test
  • Temperature resistance
  • Spring rate test
  • Movement (axial, lateral, angular and vibration) test
  • Dimensional checks
  • Fluid and chemical compatibility testing
  • Electrical properties
  • Burst destructive test
  • Fluid and Chemical Compatibility Testing
  • Chemical analysis of the elastomers
  • Rubber and Elastomer Physical Testing
  • Abrasion and erosion resistance
  • Brittleness
  • Compression Set
  • Corrosion Resistance
  • Rubber Fatigue

These controls and tests are carried out in line with the procedures and guidelines approved by the Quality Control Department which certifies such tests. These tests may be carried out, monitored and/or certified by independent companies or laboratories.
