Dear Sir or Madam,
Firstly, are you able to get access to USED steel pipe, this is the most important questions.
The pipe will be used in the Baltic sea on the coats of Latvia and Lithuania , at present they get USED pipes from Russia which have already been used previously. The general size seems to be 1220mm x12.5mm x10-12meters in length. They also use 1020-1060mmx 9.5mmx 10-12meters.
As far as construction is concerned they can accept any type of welded pipe.
So if you have the capacity, please quote your best price basis on FOB nearest port.
