Buried expansion joint for communication 'MST-V'

Buried expansion joint for communication 'MST-V'

Buried expansion joints aimed at maintaining pipeline functionality.

The "MST-V" is a buried expansion joint designed to flexibly respond to complex variations in PVC communication pipelines due to earthquakes, ground subsidence, and differential settlement measures in soft ground areas, with the aim of maintaining pipeline functionality. The main material is rigid polyvinyl chloride, and during installation, the movable parts are protected by the included poly sleeve. 【Product Overview】 ■ Main Material: Rigid Polyvinyl Chloride ■ Product Standards: In-house standards (conductivity and airtightness performance comply with the Ministry of Land, Infrastructure, Transport and Tourism, the Ministry of Defense, Tokyo Metropolitan Government, and NTT) ■ Applicable Pipelines: Mainly communication cable protection pipelines in buried sections, bridge concealment sections, and fire protection equipment sections. *For more details, please download the PDF or feel free to contact us.

Seismic expansion joint "Flexi-Joint"

Seismic expansion joint "Flexi-Joint"

Seismic expansion joints that absorb stress on communication conduits caused by ground subsidence and distortion.

The "Flexi-Joint" is a seismic expansion joint that adapts to movements such as ground fluctuations with an eccentricity of ±90mm. The ball sections on both sides can bend up to 15 degrees at one point and 30 degrees in the same direction, allowing for flexible piping. There is no need for alignment work for pipe connections, and thanks to its unique mechanism, there is no leakage, ensuring complete insulation for communication cables. 【Features】 ■ For fiber optic and power cables ■ Adapts to movements such as ground fluctuations with an eccentricity of ±90mm ■ Equipped with a generous expansion range of -60mm to +100mm ■ No leakage due to a unique mechanism, ensuring complete insulation for communication cables ■ No need for alignment work for pipe connections *For more details, please refer to the PDF document or feel free to contact us.
