On July 8, 2019, FIKE China sales manager conducted online training for our staff. The training is divided into two parts. The first part is FIKE's classic product, pressure relief device (PRD), which is used to release excess pressure in the system to protect the equipment. The second is VOC (volatile organic compounds) emission reduction solution, which responds to the national call for energy conservation and emission reduction. The blasting disc is installed upstream of the safety valve to reduce leakage and cost. FIKE is an international manufacturing company based in the United States that provides engineering solutions for process safety and equipment protection. As a qualified distributor of FIKE in China, our company has been providing bursting discs for many domestic petrochemical enterprises over the years. Through this training, we also found new opportunities. Our company will actively respond to the country's comprehensive management of VOCs and take it as an important development direction in the future.
