Over the past 15 years, China's bridge construction has witnessed unprecedented growth, creating numerous world-record-holding marvels. The number of highway bridges surged from 805,300 in 2016 to 961,100 in 2021, with an average annual increase of 31,200 structures.

Elastomeric bridge bearings are crucial components transferring loads while accommodating movements in bridge structures. This technical analysis compares American (ASTM/AASHTO), European (EN), and Chinese (GB/JT) standards, addressing critical differences in design methodology, material specifications, and testing protocols.

Inflatable pipe plugs are essential tools for a wide range of applications, including pipeline testing, maintenance, repair, and flow diversion. Their effectiveness, however, is entirely dependent on correct installation and usage. Improper handling can lead to failure, damage to the pipeline, or even safety hazards.

Elastomeric bearing pads represent a critical engineering component in modern infrastructure, serving as indispensable elements in bridges, buildings, and various structural applications. These sophisticated devices expertly balance load transfer requirements with necessary flexibility to accommodate movement, rotation, and vibration isolation.
