Design and Installation Guidance

Tungum alloy tubing C69100 special combination of high strength and ductility make it one of the easier materials to use even in very complex systems.

We have listed some design and guidance notes below. Should you have any other questions related to installing Tungum, please contact us.

Design Guidance Notes

For more detailed information please download this brochure.

Operating parameters to consider
  • Working / design pressure
  • Flow rate
  • Operating environment

These are the basics to consider when selecting tube.

Remember the corrosion resistance, cold working and clean bore characteristics of Tungum Alloy combine to give the advantage of:

  • No need for paint or other protective treatment to safeguard it from the elements
  • Reducing the time and cost incurred installing and purging a system
  • No specialist installation tools required
  • These features and benefits eliminate ongoing maintenance costs
Length of Tungum tube

Tube to specifications BS EN12449 CW700R and ASTM B706-TF00 C69100  is supplied in random lengths of 5.791 metres ( 19 feet ).


Dimensional tolerances for Tungum alloy tubing are stated in the appropriate specification – BS EN 12449 and ASTM B706.

Please refer to these specifications for full details.

To satisfy both specification’s we manufacture Tungum to tolerances that exceed these requirements.

Condition (hardness) of tube supplied

Tungum alloy tubes are solid drawn (seamless), and are supplied in the “W.P” (precipitation hardened) condition within the tensile range required to meet the appropriate specification.

For the BSEN12449 CW700R specification this is condition R430.

For the ASTM B706 UNS69100 specification this is condition TF00.


As a policy, large stocks of Tungum tubing are maintained in both metric and imperial sizes. Whilst this enables most popular sizes to be available Ex. Stock, certain of the lesser used sizes must be considered as being subject to a special order.

If the range does not include your particular size requirement, please call us to discuss.

Supporting this is our network of distributors who offer stock, technical support and advice.

See the Distributors page for details.
