Joint Yoochang Thermal System established in 1984 has shared the technical cooperation with A.T.S (U.S) do deliver the best quality of Joint thermal system throughout the world. With our continuous R&D support, we have overcome the barriers of installments of Expansion and Contraction of piping system and developed higher quality of expansion joint. Especially, our joint product shows outstanding absorption in expansion and contraction of piping system which refers to increase of efficiency in building constructions. We also developed underground Slip joint which is possible to install under the round without manhole cover and can be maintained without excavation. This procedure helps to reduce fossil fuel remarkably. Transporting steams as well as medium temperature water, gas, oil and water etc at Industrial Plant, High-rise building and District Heating is what we have done ever since our first establishment. Joint Yoochang is specialized in Industrial plant and High rise buildings where expert skills with transporting piping system such as steam, medium temperature heating water, Gas, Oil, Water are required. Joint Yoochang applied our own innovative techniques to create provisions of the high rise building’s  Column Shortening, Wind sway and Expansion Contraction from high pressure and variation of temperature in high rise buildings. Joint Yoochang Thermal System will promise to perform stable and reliable piping engineering systems to produce the world’s best products.
