Here's the deal. When I looked into this issue way back when, industry sources stated India as the sole supplier. Yes, I do goto industry sources for information. A flap over this issue has developed since then, with Trans-Canada making statements about domestic sourcing which are under Congressional investigation. Did I over-simplify? Maybe...or maybe not.
Committee Democrats to TransCanada: Immediately Disclose Origin of Steel to be Used on Keystone XL Pipeline | Committee on Energy and Commerce Democrats
TransCanada has repeatedly assured Congress that 75 percent of the steel used in the Keystone XL pipeline will be made in North America, Congressman Doyle observed. And yet, this company has been unwilling or unable to provide us with documentation to back up that statement... After looking into this issue in some detail, I have concluded that TransCanada has already purchased most, if not all, of the steel for the Keystone XL pipeline from foreign mills." U.S. Rep.

Doyle Calls for Truth in Advertising on Keystone Pipeline Jobs | Congressman Mike Doyle
(The below excerpt is from the Arkansas Times)
"I point you again to the Cornell study that has debunked the exaggerated job claims on this project, including claims of domestic jobs for steel and pipe production. For example:
It therefore seems likely that the rest of the pipe needed for KXL will probably be manufactured in Welspuns Indian plants and then shipped to the U.S for final processing (double jointing and coating) or manufactured in Welspuns Arkansas plant, which imports raw coiled steel and other production inputs (notably from India and South Korea.)
These arrangements allow TransCanada to state that approximately 75% of the pipe for the US portion of the proposed project would be purchased from North American pipe manufacturing facilities. This claim is misleading on two levels. Firstly, it is possible to purchase from a North American facility, but this does not necessarily mean that the steel was produced in those facilities. Secondly, the jobs created in Canada-while important to the Canadian economyshould not then be pitched as American jobs to the media and the American public."
