Material Procurement - Long Lead time items for Natural Gas Pipelines
I am developing a schedule for about 100 miles of natural gas pipeline in Virginia, USA. Multiple spreads, one new compressor station, upgrade to an existing compressor station, one new metering station, many road crossings including crossing of a major interstate, minor water crossings. I am not sure at this point about the diameter of the pipe - figure 16".
What are the longest lead time materials that I need to plan ahead for on this project? Any other considerations? I am new to pipeline scheduling and any help would be greatly appreciated.
Thanks,
Rachel

Valves
Hi Rachel,
It will be nice to know the actual diameter of the pipes. Valves for large pipes have to go through engineering design, and manufacturing process and valves manufacturers seem to have their hands full these days. In my few years in pipeline construction, I am yet to have a valve designed and manufactured in only 1 year.
WAEL is right about the induction bend, usually lines pipes that need more than 12 degree bending will have to go through hot induction bending process, maybe in the pipes manufacturers facilities. This is a long lead item
do you have induction bends???
on a butane pipe line from kayan petrochemical complex to jubail industrial port , 5 work packages were delayed due to lack of induction bends.
as for your road crossings it is advisable to simply use NDM jacking method... it is by far the safest and the most cost efficient method.
