Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

Dear Construction planner,

Is there soemone there who can confirm the work sequence for activities mentioned in the subject:

AFTER A/G piping installed, the sequence is as follow:

First painting (except the welds)

Second , install heat tracing (if aplicacble).

Third, hydrotest

Fourth, reinstament + final painting.

Final , Insulation.

Is this correct ??? any skilled construction planner out there.

Thanks in advance,

Carmen

Hi Carman

Thanks for the clarification.

This is for one line of pipes among many - your sequence is correct but please consider.

Welds need to be xray tested for integrity.

Hydro Test - could be air pressure test.

If the pipe is at high level then there may be  removal of falswork supports as the final task.

When all pipes are in place and connected then you will need a final test and balance before insulation

Best regards

A/G= above ground

U/G = under ground

Hi Carman

What does A/G mean? Never heard of that before.

Best regards
