It is possible to improve the seismic resistance of pipeline connections at low cost. The area occupied by ground work is small, which reduces the impact on traffic and other factors.
This is a joint for sewer pipes that can be installed regardless of whether they are new or existing, and can flexibly respond to ground fluctuations and displacements (horizontal displacement and bending displacement) caused by seismic motion. It generates minimal waste materials, is low-cost, and minimizes impacts on traffic and other areas, thereby reducing risks in case of emergencies. We offer joints that accommodate various installation conditions such as pipe type, pipe diameter, installation angle, and construction site conditions through a diverse lineup of joints. 【Features】 - There are seismic-resistant flexible joints corresponding to manholes and pipelines, as well as between pipelines. - Seismic-resistant flexible joints can be installed for various types of pipes (Hume pipes, PVC pipes, ceramic pipes, FRP pipes, ribbed pipes). - It is designed to withstand level 2 seismic motion. - The selection of seismic-resistant flexible joints can be made based on construction conditions. Please consult us first. For more details, please contact us or download the catalog.

Company information
The Imperial Hume Pipe East Japan Co., Ltd. is a company located in Minato-ku, Tokyo, that handles the sales and construction of concrete secondary products. It manufactures and sells various concrete products such as hume pipes, synthetic steel pipes, and assembled manholes (Adholes), and also produces and constructs seismic flexible joints and non-excavation seismic retrofitting work (seismic joints). ○ What is a hume pipe? A reinforced concrete pipe manufactured by compacting concrete using centrifugal force. It is mainly used as pipeline material for sewage systems. ○ What is a seismic flexible joint? It is a joint between pipes and between pipes and manholes. It can be used for new installations as well as for non-excavation seismic retrofitting work on existing manholes.
