Agru Poly-Flo - Double Containment Piping Systems

AGRU’s range of double containment pipes have proved extremely successful in a wide range of applications over a number of years and are continuing to prove their durability with the recent advances and the ever changing requirements of the chemical process engineering field.

The AGRU double containment pipes have been used successfully in a wide range of applications for many years. They fulfil today’s strict requirements in the field of chemical process engineering. AGRU’s newly designed Poly-Flo system is an expansion of their double containment piping system which has proven its value over years.

For leak detection in the double containment piping, different methods are offered and they are installed in the space between the inner and outer pipe. The simultaneous welding (heating element butt welding method) is the most commonly used connection method for piping components, ensuring an easy and cost-effective installation.

This innovative system wins over with optimal space management as well as with a cost- efficient solution.

Advantages:

Production:

  • Higher safety
  • Cost savings vs. fabricated systems
  • More uniform construction

Co-Extrusion:

  • Acts like single wall pipe
  • Fewer concerns during expansion & construction
  • Eliminate separation during directional drilling

SDR execution:

  • Full pressure rating
  • No special welding clamps
  • Similar logistics to single wall products

Installation:

  • Safe and fast installation
  • Outer and inner diameter of fitting and pipe corresponds exactly
  • Safety installation

Price:

  • Price advantage due to innovative production method
  • The pipes and fittings are produced in one step (Injection moulded, extruded)
  • No pre-fabrication of pipes and fittings required

Space:

  • Low space requirement of double containment system
  • Low weight due to small annular space
