Jianeng Technology Secures Two New Patents for Spring Supports and Hangers
Shandong Jianeng Technology Co., Ltd. has recently been granted two utility model patents for spring supports and hangers, reinforcing its position in the industrial piping support sector.
1.The first patent covers a low-profile linear constant-force spring hanger. This design addresses space-constrained installation scenarios where standard supports cannot fit, while still delivering constant load response throughout the travel range.
2.The second patent involves a monolithic pipe shoe with variable spring support, featuring a synchronized pre-compression adjustment mechanism. This allows for on-site fine-tuning during installation, reducing setup time and improving alignment accuracy compared to conventional designs that require separate adjustment steps.
On the commercial side, Jianeng Technology was awarded the winning bidder for a spring support and hanger procurement project initiated by Donghua Engineering Science & Technology Co., Ltd., with the award notice published in late May 2026. Donghua Engineering, a state-owned enterprise in the petrochemical EPC sector, has a long-standing presence in large-scale chemical and coal-chemical projects across China.
The combination of continuous product development and active project awards suggests steady market demand for engineered spring support solutions, particularly in industries where pipe stress management and thermal movement accommodation remain critical design considerations.
This procurement award adds to Jianeng's growing list of project references in the energy and chemical processing sectors, where its spring hangers are deployed alongside pipe racks, expansion loops, and rotating equipment connections.
