Is it correct to weld grounding lugs across the pipeline valve onto the valve itself?

Is the grounding lug installed correctly?
No, the grounding lug should not be welded directly to the valve; instead, it should be welded to a stable part of the pipeline to ensure effective grounding and safety. Valves themselves are generally not suitable as welding points. .
Design institutes should have standard graphics. You can ask them for it. Welding is generally not done on valves; instead, two wires are used to cross and bridge over the valve.
There are jumper wires; they are fixed at the fasteners on both sides of the flange, and they are available for purchase on Taobao. This doesn’t allow welding on the pipe, right?
It is recommended to weld it onto the flange, or use a copper plate for bridging, in order to avoid unnecessary complications when replacing or repairing the valve.
This part should be under the nut; that’s definitely not right
Hehe, it’s amazing that such strange phenomena still occur these days; it’s worth reflecting on :)
Regarding static grounding, the relevant standards only set requirements but do not specify exactly how to proceed, which leads to various practices on site. Regarding the method of static electricity bonding, the only reference available at present is the hand-drawn atlas from the 1980s titled \"General Diagrams for Static Electricity Grounding Installation in Chemical Enterprises\" CD90B4-88. Here, we pay tribute to the dedication of the experts from that era.
There are electrostatic grounding maps that you can take a look at
Just buy a ready-made crossover cable – it’s also aesthetically pleasing.
The high temperatures associated with welding also have an impact on gaskets and valve seals
