  • Materials & welding

Materials & service

  • High-temp Incoloy / Inconel for refinery flue-gas
  • SS316L for chemical service
  • Fabric layup for power-plant ducts (PTFE, glass fibre, ceramic blanket)
  • Rubber bellows (EPDM, NBR, Neoprene) for pumps and pipelines

Engineering & qualification

  • EJMA spring-rate and cycle-life calculation
  • ANSYS FEA validation for critical service
  • Squirm pressure test (column stability)
  • Cycle-life testing on representative samples
  • PMI on every bellows ply
  • Testing & documentation
