Compatible with various pipe types! Sewer pipe fittings "Seismic Flexible Joint Series"

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 newly constructed or existing, and can flexibly respond to ground movement and displacement (horizontal displacement and bending displacement) caused by seismic activity. It generates minimal waste materials, is low-cost, and minimizes impacts on traffic and other factors, thereby reducing risks in case of emergencies. We propose 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 for manholes and pipelines, as well as between pipelines. - Seismic-resistant flexible joints can be installed for various types of pipes (concrete 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 tailored based on construction conditions. Please consult us first. For more details, please contact us or download the catalog.

MESCO-made mechanical seismic joint for pipes Suppon MWX

MESCO-made mechanical seismic joint for pipes Suppon MWX

Kawanishi Waterway Machinery × Mitsui Mining & Smelting Engineering Dedicated mechanical seismic joint that maximizes the performance of MESO pipes!!

The Suppon MWX is a seismic joint designed specifically for pipes, manufactured by Mitsui Mining & Smelting Engineering Co., Ltd. (MESCO), that does not require disassembly. It accommodates nominal diameters from Φ40 to Φ200. The allowable water pressure can reach up to 2.0 MPa using a dedicated in-core. It can be installed without the need for flange processing or welding work when connecting bridge-mounted pipelines, and can be put into service immediately after installation with just one wrench. Additionally, it does not require special tools, allowing for installation unaffected by environmental conditions (weather or mountainous areas). - The pipe-on-slide connection allows for easy adjustment and alignment between bridge piping and buried piping. - There is a wide range of options available for connecting MESCO pipes with other types of pipes (such as PVC and cast iron). - There is a rich lineup of products ideal for installing mechanical soft-seal shut-off valves and fire hydrants that eliminate the risk of leakage from shut-off valves.
