The helical pipe is made of high-grade steel 316L, and stress relief annealed.

Fittings are male or female, couplings, elbow, T-pieces, clamp connections etc. all in brass.

Tubes are available in rolls which allows for easy transport and storage.

Suitable for all standard pipe fittings and insulations.

The connection is always made with a graphite cone sealing.

Advantages helical tube versus copper tube in solar-systems:

  • 316 stainless steel is used as material, ensuring high pressure resistance and good heat transfer,
  • The assembly is extremely easy and the joints can be made on the spot without any special tools,
  • Significant reduction in costs due to reduced installation time no soldering required,
  • A unique conical sealing ensures high temperature stability and a 100 % tightness,
  • Small dimension ( roll) ensures low weight for transport.

Typical applications:

  • solar industry
  • cold/hotwater
  • heat exchangers
  • repair pipe
  • steam and trace heating
  • vessel connections
  • pipe for heat pumps
  • other fluides

Advantages helical tube versus annular tube in solar-systems:

  • No air bubbles during system filling due to helical design
  • 20-50 %(depending on size) more flow volume compared to annular type
  • No deposits because of to helical design
  • A unique conical sealing ensures high temperature stability and a 100 % tightness
  • The assemply is extremely easy and the joints can be made on the spot without any special tools
