Investigation of the former Thai Zhou Bridge Pipe Factory
WASHINGTON —On June 18, 2025, U. Customs and Border Protection (CBP) issued its notification of initiation of investigation and interim measures as to evasion by Amek Aluminum & Stainless, Inc. ; American Pipe Products Inc. The US Department of Commerce announced the preliminary results of its dumping investigation into Thai circular welded carbon steel pipe (CWP). While backing the inquiry, the embassy also condemned what it described as " smear campaigns " and distortions of facts. A recent investigation reveals that mountain torrents and flooding led to a catastrophic bridge failure in Shaanxi Province, resulting in significant loss of life. Google Scholar provides a simple way to broadly search for scholarly literature. Numerous Thai government agencies are investigating two Chinese companies responsible for the construction of the collapsed State Audit Office in Bangkok, with probes expanding to many other related companies, according to the Ministry of Commerce. The investigations focus on China Railway.

The Role of Seismic Bracing for Pipe Cable Trays
Suspended systems such as piping, equipment and ductwork need seis-mic braces to keep them from swaying during an earthquake. Why is seismic bracing important? International Building Code. This article will explore the importance of seismic resistance in cable trays, discuss when seismic braces are necessary, and help you understand how to make informed decisions for your installation. Before diving deeper into the specifics, it's important to understand the various factors that. Seismic bracing, typically made of high-strength metal, is key component specifically designed to enhance the stability and safety of cable tray systems during earthquakes. Seismic braces can be flexible using aircraft quality cables, or rigid (solid) using steel sections such as pipe, angles, or strut channels. Braces are typi-cally installed. Technical overview of seismic cable tray design considerations including bracing splice reinforcement movement accommodation cable retention and support verification. ) and components (HVAC duct, conduit/cable tray, and piping) within a building or structure to minimize damage.

Spacing of fire protection pipe cable trays
All sizes above are measured from the outer edge of the services. Cables within cable trays can be bundled together into a maximum 100mm diameter bundle and each bundle should be spaced 50mm apart from each outer edge. Cable trays and pipes work together to manage the flow of electricity, fluids, and gases, with cable trays primarily supporting electrical cables, and pipes transporting liquids, gases, and other materials. In complex industrial environments, these components often overlap or interconnect, making. In passive fire protection (PFP), separation distance is the minimum space required between services (e. 8 (Other Mechanical Stresses (AJ)) in that document provides requirements for cable support.
