Procurement period of pipes

My poject is using CS pipes 20" dia. or more, and fittings previosuly estimate 33 wks of lead in time but the vendour is quite quick getting it ready in 20 wks.

Call your vendors for more accurate answer. Don’t rely on planners, because planners do also ask suppliers for this kind of information.

It depends upon your supplier exclusively. His factory profuction capacity, stock at that period and projects in his hand.

So, its better to call ur vendor rather than asking from planners.

I have been trying to get CS tube and the lead time varies from country to country.
Sometimes the client insists that tube or pipe has to be of european or Nth American origin which can be a lead time of 35 weeks (especially if its seamless & not welded). Whilst I have been getting better lead times from China and Estonia.
Our procurement dept are now trying every corner of the globe.
