Isolation Balloon Type 2 - Obtained Major 5 Classifications
【HEXA TIMES】No.2 The isolation balloon type 2, developed for isolation during the maintenance of LNG ship safety valves, has obtained certification from the five major classification societies: NK (Japan), ABS (United States), LR (United Kingdom), BV (France), and DNV (Norway and Germany). This product responds to the revision of the IGC Code, which requires "a means to temporarily isolate safety valves during maintenance," and has become an essential system for LNG vessels constructed after July 1, 2016. Additionally, by using this product, it is possible to reduce costs by eliminating the need for additional valves.
Post-installation water shut-off confirmation is possible! The manhole structure features an easy-to-open and close pin insertion mechanism operated by a handle.

A water stop wall / hexagate plug (HGP) has been adopted for the Chubu No. 7 trunk line.
The Fukuoka City Water and Sewer Bureau has adopted the Hexa Gate Plug (hereinafter referred to as HGP) for the construction of the sewer system in the Fukuoka (Imaizumi 2-chome 2) outer area (Contractor: Ando Hazama). This project is part of the "Rainbow Plan Tenjin," a rainwater drainage facility development plan aimed at preventing flooding damage due to expected guerrilla rainstorms in the Tenjin area. The project involves the construction of a rainwater conduit, and this HGP is installed as a temporary wall within the existing Chubu No. 7 main line, where the inspec-through line (shield method) connects, protecting the shield arrival section from rainwater.
We protect underground structures from risks such as flooding due to storms and tsunamis, and fire spread from nearby fires! [Video available]
