The above table gives the calculated minimum elongation values for various nominal wall thicknesses. Where the specified nominal wall thickness is intermediate to those shown above, the minimum elongation value shall be determined as follows:
Grade
1. E=48t+15.00
2. E=40t+12.50
3. E=32t+10.00
where:
E = elongation in 2 in., %, and
T = specified nominal wall thickness, in.

 

Tolerance of Outside Diameter, Wall Thickness, Length and Weight:

Outside Diameter The outside diameter of pipe piles shall not vary more than ±1% from the specified outside diameter.
Wall thickness The wall thickness at any point shall not be more than 12.5% under the specified nominal wall thickness.
Lengths Pipe piles shall be furnished in single random lengths, double random lengths, or in uniform lengths as specified in the purchase order, in accordance with the following limits: Single random lengths    16 to 25ft (4.88 to 7.62mm), inch
Double random lengths      Over 25ft (7.62m) with a minimum average of 35ft (10.67m)
Uniform  lengths        Length as specified with a permissible variation of ±1 in.
Weight Each length of pipe pile shall be weighed separately and its weight shall not vary more than 15% over or 5% under its theoretical weight, calculated using its length and its weight per unit length.
