Seeking unprecedented cost performance because of the integrated resources and expertise for expansion joint
Bellows expansion joints, the main product of the Expansion Joint (EJ) Division, are applied in a wide range of industrial facilities, such as urban gas installations, electric power plants, iron making plants, petrol and petroleum chemistry plants, liquefied natural gas (LNG) and liquefied petroleum gas (LPG) plants, and carrier vessels. They are evaluated highly for their industry-leading performance. Technoflex&Tola holds an overwhelming production share particularly in the field of large-diameter (10m) expansion joints for nuclear power plants, where we outclass all our competitors. We have always played a role as a pioneer in the expansion joint field, developing community central heating and air-conditioning leak detection systems and for underground two layers piping systems, as well as plastic coated expansion joints for underground piping, joints for earthquake-reducing buildings, and reinforced materials for oil retaining and liquids retaining walls. In order to respond to overseas competitiveness we will seek further improvements of cost performance through utilization of our domestic and overseas production bases as well as of the technical capacity based on our rich experience.
