Azumi produces various underground materials using its own manufacturing technology such as adapters for prefabricated manhole pipes, prefabricated connecting pipes, and connecting pipes for PE pipes. Azumi’s current flagship underground material is an electro-foamed fusion PE connecting pipe applied with its own technology. The distance of heating elements coated with glass fiber is separately fixed, thus effectively preventing the heating element’s short circuit and the increase in temperature of dual sheet’s dual parts, respectively.
Thanks to the built-in temperature measurement sensor, reliability and safety in construction are considerably increased as the temperature required in foaming and fusion is delicately controlled.
Currently, Finland is playing a pivotal role as an export mainstay, including European countries, the U.S.A., China, and Japan. Established in 1998, the company has been striving to acquire related patents and register new designs for practical uses, in an attempt to secure competitive technology against comparable products worldwide.
