In the Sinopec Engineering Incorporation "pipeline electrostatic grounding design regulations", "static grounding connection material selection table" mentioned in the flange plate, what is that?
You may refer to the resistance between the two gas pipeline flange of the connecting plate is less than 5 ohm, usually used 2-3mm copper, 25-30mm width 200-250mm length, the two flange two screw holes connected tightly to the recent. There is also the key to the selection of aluminum plate is to ensure that the grounding resistance value. The design drawings shall be subject to the requirements.
The flange connection is a machine with a flange at the back and a hollow shaft used to connect the motor. This is called the connecting flange
What we do in SINOPEC are all cross wiring, do two pieces of welding in the flange at both ends of the pipe wall, and then connected with copper wire.
