  API Cold Rolls

Drill pipes undergo repeated, severe tensile stresses during a drilling operation. These cyclic stresses are particularly focused on the thread roots and can cause premature pipe failure. Cold Rolling is a method in which the material introduced between rollers is compacted and compressed. The amount of force we introduce controls the hardness and other material properties of the finished product.
