JU-3W, 4W Ball Joint

Measures for piping expansion/contraction, earthquakes, and land subsidence for building facilities, air-conditioning facilities, factory facilities, seismic isolation buildings, etc.

· In addition to expansion and contraction in the axial direction of piping caused by temperature changes, it absorbs other pipe displacements including axis movement, bending, twisting, etc., caused by ground subsidence, earthquakes, and so on.
· It is used in skyscrapers, regional heating and cooling purposes, plants, storage tanks, factories, etc.
· Use of super packing ensures excellent seals.
· Large displacement is available within limited spaces.
· The small amount of force exerted on the anchor enables the size of the anchor to be reduced.
▪ Piping movements such as thermal expansion or ground subsidence can be absorbed simultaneously.
