Hydrostatic Test

Each length of pipe shall be tested by the manufacturer to a hydrostatic pressure that will produce in the pipe wall a stress of not less than 60% of the specified minimum yield strength at room temperature. The pressure shall be determined by the following equation:
P=2St/D

Permissible Variations In Weights and Dimensions

Each length of pipe shall be weighed separately and its weight shall not vary more than 10% over or 5.5% under its theoretical weight, calculated using its length and its weight per unit length.
The outside diameter shall not vary more than ±1% from the specified nominal outside diameter.
Wall thickness at any point shall not more than 12.5% under the specified wall thickness.

Length

Single random lengths: 16 to 25ft(4.88 to 7.62m)
Double random lengths: over 25ft to 35ft(7.62 to 10.67m)
Uniform lengths: permissible variation ±1in

Ends

Pipe piles shall be furnished with plain ends, and the burrs at the ends shall be removed
When the pipe end specified to be bevel ends, the angle shall be 30 to 35 degree
