【HaiChuan Pipeline Discussion】Is it a good idea to connect the valve to the pipe segment first before bringing them together?

Anyone who can play this kind of thing is an experienced player :)
In the future, when removing the valve, it may not be possible to maintain the same dimensions
It can only be installed in this way; otherwise, scaffolding must be set up for positioning.
Shouldn’t there be an operating platform at the valve position?
For example, when tightening nuts, due to space constraints and safety considerations, it may be necessary to build temporary scaffolding; the existing operating platforms do not meet the actual requirements. Therefore, in actual field applications, ground pre-tensioning is generally used. After all, installation and subsequent maintenance are not tasks carried out by the same team; one should first take care of their own responsibilities, leaving the rest to others.
This is correct; the ground does these things well, ensuring safety, improving efficiency, and facilitating supervision and inspection
Before lifting, check whether the interiors of the two pipe sections are clean
So, there are advantages and disadvantages to each. After the ground is prepared and lifting and welding are carried out, it becomes extremely difficult to replace the valves later on, as there is no longer any possibility of adjusting the elastic distance. Commonly known as a “job that destroys families”!
