三井金属エンジニアリング List of Products and Services

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 piping, 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, mountainous areas). - The pipe-on-pipe sliding connection allows for easy adjustment and alignment between bridge piping and buried piping. - There is a wide range of compatible connections between MESCO pipes and other types of pipes (such as PVC and cast iron). - There is a rich lineup of products ideal for the installation of mechanical soft-seal shut-off valves and fire hydrants that eliminate the risk of leakage from shut-off valves.

This catalog introduces a variety of pipes and fittings in different shapes, along with examples of construction for various applications. It also covers fusion connections and mechanical connections as methods for connecting pipes and fittings. You can also check the tool rental service and methods for transporting and storing pipes, which will be helpful for product selection and construction method considerations. 【Featured Products】 Pipe Products ■WED ■WE ■WEETDA/WEETA ■GNGWDA/GNGWA ■WNG/WEETS ■PXE ■GNGAR ■GNGRT Fitting Products ■Various Fitting Products ■EF Fitting Connection ■Butt Fusion ■Connection Short Pipe Quick Reference ■Discharge Manhole Connection Diagram ■Mechanical Fitting Others ■Tool Rental ■Properties of Polyethylene ■From Delivery to Construction *For more details, please refer to the PDF document or feel free to contact us.

Lightweight and highly corrosion-resistant polyethylene pipes offer significant advantages over traditional metal pipes in terms of workability and durability. They have received high praise in infrastructure development focused on seismic resistance, and the trend towards larger diameters is rapidly advancing in the fields of water supply, sewage, and industrial piping. Among these, Mesco pipes provide consistent support from design to construction, demonstrating strengths in the construction technology of large-diameter piping. In particular, in exposed techniques (including bridge attachments), we have established safe and efficient construction methods that consider structural conditions and surrounding environments, thereby building reliable lifelines. Furthermore, installation locations vary widely, including buried, exposed, mountainous, bridge, and underwater settings, achieving high durability and workability even under harsh conditions, contributing to the creation of disaster-resistant social infrastructure. ◆Exhibition Information◆ We will be exhibiting at 'InterAqua 2026'.
