Inspection for long range microbore tubes by using sensor equipment with guided wave


A Korean research and development laboratory for electricity has developed the technology for testing pipelines by using long range microbore tube with guided wave. The technology is suitable to examine inside and outside defects and searching thinning-wall of the pipe. The technology is valuable for various pipeline related industries. The company prefers to cooperate with partners based on commercial agreement with technical assistance, research cooperation, licensing and services agreement.

Partner sought

- Type of partner sought: SME or large enterprise preferable with experience in consortium - Specific area of activity of the partner: Any partners especially construction companies, manufacturers and power stations are appreciated. Cooperative work is possible with partners who need pipes as their equipment such as for water, steam, oil, and chemicals. - The task to be performed: It would be great to work together with partners who have diverse experience in real field based on theoretical knowledge about signal analysis for distinguishing signals of thinning pipe are appreciated. For cooperative partnership, the company wants to share specific rights and advice about technology based on license agreement and commercial agreement with technical assistance. Moreover, with both research cooperation and services agreement, the company tries to find partners who are cooperative for develop and improve the technology together.


A Korean research laboratory is affiliated with a public enterprise. The laboratory is a central research institute in Korea which plays a pivotal role in the electric power industry. Over 50 years, the laboratory is developing and supplying technologies related to electricity. The laboratory is now considering to fulfill technological demands in electric power industry with developing technology in the new energy industry as a next growth engine in Korea. The laboratory offers technology for examining pipelines by long-range microbore tube based on the guided wave principle. The purpose of the technology is to identify damage from inside or outside of the tube and a partial thinning condition of the pipe by using the principle of the Piezo-activated guided wave. In the fixed position, the technology enables the faster test of 200meter distance by signal exchange for one time. The technology strengthens the contact force outside of the tube by using tension springs. Furthermore, it is possible to analyze and evaluate in a stable way because of built-in sensors for guiding the operation. There are several examples of application including demonstration case. The technology is applied to test pipes for firefighting and industrial water, boilers and reheat steam in power stations. Furthermore, it could be utilized to evaluate the condition of gas pipelines in several Korean gas and oil companies. It also supports the integrity assessment of equipment for renewable energy such as inspecting gantries for offshore wind power generators. Furthermore, the technology would be applied to the construction industry by testing integrity about underground pipelines including those under bridges. The type of partnership would be based on commercialization with technical assistance, licensing, research cooperation and services agreement.

Advantages and innovations

The aim of the technology is to solve the main drawbacks while enhancing the advantages of the existing way of pipe testing. Most microbore tube has small parameters (less than 60milimeters). This condition makes impossible to affix sensors so it is necessary to use other instruments for widening the gap in tubes in a forceful way. However, this technology facilitates the test with tubes which distance is more than 50milimeters as the size of equipment for detecting and measuring is less than 60 millimeters. Moreover, the test is bidirectional in long range by one operation. Therefore, the time and cost required could be cut into almost half comparing with general local examinations while increasing credibility of the test.

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
