Invitation Letter | SGR Invites You to the 29th China International Trenchless Technology Seminar and Exhibition, Tianjin

 SGR will be exhibiting at the 29th China International Trenchless Technology Seminar and Exhibition (ITTC2026)

Dates: April 22-24, 2026

Location: National Exhibition and Convention Center (Tianjin), Halls S13 and S14

Booth No.: A21

The annual premier event for the trenchless industry is highly regarded by professional attendees and buyers

With the assistance of the China Machinery Industry Association and the professional guidance of international associations such as the Trenchless Technology Committee of the Geological Society of China, the International Association for Trenchless Technology, and the Japan Trenchless Technology Association, the 29th China International Trenchless Technology Seminar and Exhibition (ITTC2026) will be held from April 22nd to 24th at the National Exhibition and Convention Center (Tianjin).

The annual China International Trenchless Technology Seminar and Exhibition (ITTC) is showcasing the vibrant energy and development potential of China's trenchless technology industry with an unexpectedly large scale and a wealth of cutting-edge technologies. Feedback from exhibitors and visitors at previous symposia indicates that ITTC reflects the growing demand for trenchless technology in China's national economic development. The active participation of international experts and speakers, along with the large influx of international professional visitors and buyers, demonstrates the international market's attention to and recognition of China's trenchless technology development.

 SGR reducers are widely used in trenchless horizontal directional drilling rigs

Horizontal directional drilling rigs are construction equipment used to lay flexible underground pipelines without excavating the ground surface. Their working principle is to control the drill bit to move underground along a predetermined trajectory through a guiding system. First, a pilot hole is drilled, then the hole diameter is enlarged through a hole-reaming operation, and finally the pipeline is pulled back into the hole, thereby achieving trenchless crossing under obstacles such as roads, rivers, railways, and buildings.

The N-series trenchless horizontal directional drilling reducer, developed and manufactured by SGR plays a crucial role in driving the rotation and propulsion of the drill rod in horizontal directional drilling rigs. Based on the principle of power splitting and combining, the N-series reducer uses internally and externally meshing planetary gears for transmission, resulting in high power density, strong load-bearing capacity, and diverse power options, including conventional motors, hydraulic motors, or permanent magnet motors. The gears are made of high-strength alloy steel, quenched and ground, offering high strength, good wear resistance, and a long service life. The reducer uses a ductile iron housing, exhibiting low impact deformation and high strength.

SGR provides a full range of N-series trenchless horizontal directional drilling reducers in various specifications. The push-pull reducers have a reduction ratio of 12-52 and a torque from 2000 Nm to 80000 Nm, while the rotary reducers have a reduction ratio of 5-20. Mass production is available, with fast delivery, and can meet the application needs of various scenarios.

 We cordially invite you to visit the exhibition and discuss the trends and future of trenchless technology.

From April 23rd to 25th, 2025, SGR made a grand appearance at ITTC2025 with its N-series planetary gear reducers and C-series worm gear reducers, bringing high-quality mechanical transmission solutions to the audience.

With ITTC2026 just around the corner, SGR will continue to bring you high-quality planetary gear reducers and worm gear reducers. SGR's business and technical teams will also be on-site to explain product principles and technical solutions, addressing all your concerns when purchasing reducer products.

From April 22nd to 24th, join SGR at booth A21 in Halls S13 and S14 of the Tianjin National Convention and Exhibition Center. See you there!
