Discussion on Electrostatic Grounding and Flange Bridging
Static electricity protection and lightning protection are important contents in the safety disaster prevention of petrochemical unit.There is much debate on the requirements and implementation for static electricity grounding and metal flange bridging.Starting from the basic conception and principles,the requirements and characteristics of electrostatic protection and lightning protection based on current standards and specifications with combination of engineering practice are analyzed.The contents on the aspects such as electrostatic discharge and grounding,electrostatic bridging of flanges,relevant in standard requirements,and the origin of 0.03 Ω resistance are discussed with emphasis.Engineering suggestions and issues to be noted are put forward.
