Shown above are specifications associated with steel pipe and water well casing manufacture, their strength requirements, and chemistry as applicable. Titles and grades have been abbreviated in some cases for clarity.

While many pipe specifications cite manufacture from some of these raw material specifications others do not, relying on testing of the finished pipe to assure compliance with physical requirements. In such cases the manufacturer may order raw material according to one of the specifications above, another standard as agreed, or to a steel chemistry which taking in consideration physical changes occurring in the manufacturing process results in the desired product.

The differences between plate, sheet and strip are dimensional but are related to some extent to the mill process used to manufacture the product from the slab stage. This causes some confusion since pipe is manufactured from all three categories. ASTM A 635, a specification frequently used by manufacturers of ERW and spiral seam pipe, covers coils with plate thickness.
