Strong Alliance: JIANGJI Machinery Partners with OBIT Terahertz to Build a New Safety Defense Line for Beijing Subway

At a critical juncture in the high-quality development of rail transit construction, an industry collaboration focused on public safety has officially been established. On July 9, 2025, JILIN JIANGJI Machinery Manufacturing Co., Ltd. (hereinafter "JIANGJI Machinery") and OBIT Terahertz Technology (Beijing) Co., Ltd. (hereinafter "OBIT Terahertz") formally signed a strategic cooperation framework agreement. The two companies will jointly provide professional-grade explosion-proof safety equipment for Beijing Subway Line 3 and Line 13, adding a "hardcore" safeguard for the operational safety of the capital's rail transit.

Agreement Finalized, Precisely Addressing Subway Safety Needs

According to the agreement, JIANGJI Machinery will supply OBIT Terahertz with various explosion-proof products, including spherical explosion-proof storage and transport tanks, protective covers for spherical explosion-proof storage and transport tanks, explosion-proof blankets, and hazardous material storage tanks, totaling approximately 130 units. This equipment will be designated for use on Beijing Subway Line 3 and Line 13, focusing on resolving safety pain points in rail transit scenarios, such as temporary storage, transport, and emergency response to hazardous items.

As a well-known machinery manufacturing enterprise in the Jilin region, JIANGJI Machinery leverages its technical expertise in special equipment manufacturing. Its spherical explosion-proof storage and transport tanks are renowned for their high-strength explosion-proof performance, lightweight design, and ease of operation. OBIT Terahertz, a technology enterprise deeply involved in terahertz technology and public safety solutions, aims to integrate high-quality equipment resources through this procurement to create a full-chain "detection-storage-disposal" safety protection system for the Beijing Subway project.

Technology Empowers, Adding a "Protective Shield" for Subway Safety

Beijing Subway Line 3 serves as an east-west backbone line running through the city center, while Line 13 is a "city lifeline" connecting core areas like Haidian and Chaoyang. Both lines experience enormous daily passenger traffic, presenting significant operational safety pressures. The spherical explosion-proof storage and transport tanks deployed this project utilize a multi-layered composite explosion-proof structure, effectively isolating blast waves and fragments from an explosion. The protective covers further enhance the equipment's weather resistance and concealment. The explosion-proof blankets can be quickly deployed and flexibly positioned, covering hazardous sources immediately in an emergency to minimize harm to passengers and facilities.

"The safety of rail transit allows no margin for error. Our cooperation with JIANGJI Machinery is precisely based on the reliability and technical adaptability of their products in practical scenarios," stated the project leader from OBIT Terahertz. The equipment will form a grid-based safety protection network across subway stations using a "fixed-point storage + emergency response" model, building a solid safety barrier for passenger travel.

Industrial Synergy, Exploring New Paths for Public Safety

This cooperation is not only a "two-way effort" between the two companies but also a microcosm of collaborative innovation between the special equipment manufacturing and public safety technology sectors. A leader from JIANGJI Machinery noted, "Providing equipment support for a major public project like the Beijing Subway is both a responsibility and an opportunity. In the future, we will continue to optimize product performance and contribute to the safety construction of urban rail transit in more cities."

Following the signing of the agreement, both companies have initiated the production and commissioning of the first batch of equipment, which is expected to be delivered and put into use on Beijing Subway Line 3 and Line 13 soon. Industry analysts believe this cooperation sets a precedent for "equipment + solution" synergy in the field of rail transit explosion-proof safety and provides a practical reference for improving safety standards in future urban rail transit systems.

Safety is the lifeline of rail transit. The partnership between JIANGJI Machinery and OBIT Terahertz not only injects new safety momentum into the Beijing Subway but also demonstrates corporate responsibility and commitment to using technological innovation to safeguard public safety. In the future, as more intelligent and efficient safety equipment is deployed, the urban rail transit safety protection system will become increasingly robust, providing more solid guarantees for citizen travel.
