Secondary Steel Pipe for Piles

Secondary Steel Pipe for Piles

(OP)
Secondary Steel for Steel Piles

RE: Secondary Steel Pipe for Piles

Same as you, I was thinking something like "recycled".
No, the website (link below) proved us wrong, it is a steel processing after the primary steel making. You may gain more info on "secondary pipes" by gooling.

RE: Secondary Steel Pipe for Piles

What type of pile are we talking about here?

Standard practice for drilled micropiles (also called bored-in piles by NYSDOT) is to use flush joint threaded mill secondary steel casing.  Material certifications are not available for this type of material, so some agencies require random coupon sampling.

And, yes - the 2007 NY State Building Code does recognize micropiles.

RE: Secondary Steel Pipe for Piles

If I may add: Secondary pipe are oil industry rejects, i.e. pipes that don't quite meet API specs.

RE: Secondary Steel Pipe for Piles

(OP)
The piles are 10 3/4" diameter, and should be if not API rejects, ASTM A252, as per IBC.
