ZK International Develops Intelligent Piping System - A Smart Pipe Revolutionizing the Industry

WENZHOU,China,July 18,2018 -- ZK International Group Co.,Ltd. (Nasdaq: ZKIN) ("ZKIN","ZK International" or the "Company"),in conjunction with its wholly owned subsidiary,xSigma Corp.,reveals the development of the world's first smart pipe revolutionizing the stainless steel piping industry. This Intelligent Piping System (IPS) will be powered by TNT Blockchain's patent pending,software and IoT technology.

The IPS' far-reaching new technology will ensure delivery of clean drinking water from its source to the consumer. It will use sensors to detect water quality and fluctuations in temperature,pH levels,and any undesirable particles,which is a process that does not occur today. Water quality readings are done at certain points,but not throughout the entire piping system. This will allow monitors to help the water supply company and engineers detect the source of any problem that occurs to the pipe system,resulting in a much quicker resolution. Similarly,in gas pipelines,the IPS sensors will work to detect gas pressure changes,which may be an indicator of gas leakage.

David Christensen,President of TNT Blockchain commented,"We are thrilled to begin using our one of a kind technology with ZK International's manufacturing and operating process. This is truly revolutionary to the traditional piping industry with commercial and residential uses that are endless. It will ensure quality water is delivered where it is necessary,and it will monitor the integrity and safety of transporting natural gases."

Mr. Jiancong Huang,Chairman and CEO of ZK International,stated,"ZK International was founded on being a forward thinker in the stainless steel and piping industry. We have prided ourselves on incorporating technologies into our products to ensure we are always providing the best quality product to our customers and end users. The development of the Intelligent Piping System was a natural progression for us."
