Static grounding of pipes and valves
Thread Content
Dear sea friends: Static bypass wires should be installed on both sides of the valves in pipelines with high flow rates in chemical plants. Is there an intuitive way to determine, without calculation, what pipe diameter requires an electrostatic bonding wire?
It can be seen from the installation of fixed supports on the pipeline
Paragraph 5.1 of the \"Regulations for Static Electricity Safety Inspections in Chemical Enterprises\" stipulates as follows: \"When metal equipment is connected to other metal equipment, or pipes are connected to each other using metal flanges, it is not necessary to use additional bonding wires.\" But there must be more than two bolts for connection. ” Code for Lightning Protection of Oil and Oil Facilities 4.6.1: Oil pipelines can be used as their own lightning conductors, and metal bonding wires should be installed at the connections of their flanges and valves. When the flange is connected using 5 or more bolts, it is not necessary to use a metal wire for bridging, but an electrical path must still be established
All components of our company’s compressors need to be connected
All flammable and explosive pipelines should be statically grounded
