In Reply to Liju P R at 14:50 Apr-18-2019 (Opening).

Several papers can be found on NDT.net that relate to TOFD on HDPE butt fusion joints.
Carlos Correia is perhaps the most recent: https://www.ndt.net/article/ndtnet/2017/1_Correia.pdf

We provided an example of HDPE TOFD using low velocity polymer wedges: https://www.ndt.net/article/ndtnet/2016/11_Ginzel.pdf

Late in 2018 Innovation Polymers introduced the TOFD wedges that use interchangeable inserts of different acoustic velocities to permit different refracted angles; https://www.ndt.net/search/docs.php3?id=23490&content=1


Product Spotlight

Exertus Dual 120

The Exertus Dual 120 Projector has the ability to accept Iridium 192 sources or Selenium 75 source
s. This projector incorporates design and safety features that make it flexible, compact and lightweight. The Projector is lighter than most of its competitors. It incorporates an improved source channel, based on a new helicoidal design, which makes maintenance easier. The helicoidal design also allows smoother movement of the source assembly inside the device, making it easier for the operator and improving safety. The Projector also has a unique safety feature not found in competitive products. The source assembly locking mechanism is triggered by the source holder capsule at the front of the source assembly, thereby always assuring the operator that the source has returned to the safe position. The Exertus Dual 120 is ISO3999:2004 compliant.
