UL fire Pipe

UL Fire Pipe
UL Fire Pipe, also known as a standpipe, is a specialized pipe designed exclusively for firefighting applications. Made from robust materials that can withstand high temperatures and pressures, it’s the preferred choice for many commercial and industrial buildings worldwide. These pipes undergo rigorous testing and inspection by UL, an independent safety organization, ensuring they meet the highest safety and performance standards. Furthermore, our UL Fire Pipe is equipped with unique fittings for quick connections to fire hoses and other firefighting equipment. At UNIACERO, we prioritize safety, and our UL Fire Pipe is a testament to our commitment.
UL Fire Pipe Specification
Our UL Fire Pipe is available in a range of coatings, including galvanizing, FBE, and varnish coatings, each offering distinct advantages. With a coating thickness ranging from 250 microns to 550 microns, our pipes are designed to resist corrosion, UV rays, and chemicals. They operate efficiently in temperatures ranging from -30°C to 80°C and can handle pressures from 0.1 Mpa to 0.25 Mpa.
