SPECIAL OVERLAYING

Special Overlaying Technology for Concrete Pumping Applications

KMT’s patented overlaying technology is leading an innovation of Concrete Pumping Parts.

To talk about this phase in the technology, it is necessary to address Dr.Nam,Kee-Seok in KIMS(Korea Institute of Material Science).
He had studied the overlaying technology to improve a wear-resistance of pipe. He was wondering if this technology would be able to be applied to a pipe for concrete pumping applications. And then, the cooperation development between KMT and KIMS started.
But it was not easy to develop a new technology. They had to undergo many trial and errors on a component proportions and heating conditions and so on. The days that they had to face another problem after they had solved a problem continued. They pursued their own technologies, continuing by a process of trial and error, until they eventually developed their own overlaying technology for concrete pumping applications. The R&D support program from Korea Government (Ministry of Trade,Industry and Energy,Ministry of SMEs and Startups) was also great help to them at these days.
It took over 7 years for them to finish their development and then they named their own pipe for concrete pumping applications as “EXLOY 1000”. The meaning of “EXLOY 1000” is an excellent alloy which has a 1,000 HV(Hardness of Vickers).
They had a lot of trouble with commercialization & industrialization although they had developed a new product applied to a new technology.
This was mainly because there was no general awareness of a pipe for concrete pumping applications in Korea at that time. The mistaken belief of “inserting another pipe inside of a pipe would be the only way to increase a service time of the pipe” was strongly held by many people.
KMT has made a constant effort to overcome this kind of concrete pumping applications user’s mistaken belief.
At the result of those efforts, not only concrete pumping applications manufacturers but also concrete pumping applications users love EXLOY 1000 very much now.
We have been fielding a growing number of inquiries from South Korea, the U.S., and many countries in Europe about representative KMT products, but we are certain that these products cannot be imitated by other companies.
