Shanghai Lianyu Industrial Co., Ltd. is a leading manufacturer of anti-seismic hinges and seismic pipe support systems in China, We offer ISO & UL certified seismic components for industrial, commercial, and infrastructure projects. Our anti-seismic hinges, connectors, and energy-dissipating joints are designed to absorb and dissipate earthquake energy, ensuring structural integrity, pipeline stability, and safety in seismic-prone regions.
Our Anti-Seismic Hinges & Seismic Components Include:
1️⃣ M12 & M16 Anti-Seismic Hinges
-
Designed for longitudinal and lateral seismic support in pipelines and structural frames
-
Compatible with ANCUL-type steel and channel nut connections
-
Surface-treated with electro-galvanized or hot-dip galvanized coatings for superior corrosion resistance
-
Load Capacity: M12 – 14 kN | M16 – 14 kN
2️⃣ Adjustable Hinge C
-
Ideal for single-pipe longitudinal seismic support
-
Handles multi-directional tension and shear forces
-
Made of S235JR steel (DIN EN 10025) with electro-galvanized, hot-dip galvanized, or Dacromet finishes
-
Recommended force: 7.5 kN | Torque: 40 N·m | Thickness: 6 mm
3️⃣ 90° Four-Hole Corner Connector
-
For 90° two-dimensional seismic bracing connections
-
Enhances structural strength and stability

4️⃣ Friction-Based Plastic Hinge (PH) Joint
-
Innovative seismic fuse for beam-to-column joints
-
Uses frictional energy dissipation to prevent brittle failures
-
Allows quick post-earthquake repairs
-
Tested models PH-1 and PH-2 demonstrate high ductility (coefficients 2.75 & 3.14) and plastic rotation angles >0.03 rad
5️⃣ Energy-Dissipating Self-Centering Hinge (EDSC-HJ)
-
Features elastic recovery mechanisms and dampers
-
Reduces seismic displacement and vibration response by 60–70% compared to conventional frames
-
Minimal residual deformation ensures pipeline and structure safety
