Tough Jay

Allowable pull-out of up to 5mm in the consideration of Level 2 during an earthquake! It can also be used for diagonal connections.

"Tough J" is a construction method that is strong against live loads and soft ground at all times, preventing pipe bending and, during earthquakes, absorbing the load on pipe joints caused by ground displacement, ensuring the safety of pipe functions. With tension washers, it has the function of preventing longitudinal bending of pipes under normal conditions and following longitudinal bending deformation during earthquakes. Additionally, it absorbs displacement by collapsing under a certain load, preventing excessive stress on bolts and maintaining the integrity of the joint function. 【Features】 ■ Adopted in the sewer pipe rehabilitation method "RPC method," which has obtained technical review certification from the Japan Sewerage New Technology Organization (public interest incorporated foundation). ■ As a seismic connection joint, it allows for a maximum pull-out of 5mm in the consideration of earthquake level 2. ■ Prevents pipe disconnection and maintains the meandering slope of the pipeline, fulfilling the function of maintaining the flow path. *For more details, please refer to the PDF materials or feel free to contact us.
