Norris Steel Sucker Rods are manufactured from
micro alloyed, modified, special
bar quality hot rolled carbon or alloy steel.
Bar and sucker rod dimensions
and tolerances conform to API
Spec 11B, latest edition, and AISI Steel Products Manual. Sucker
rods
are available in 5/8" (15.88mm), 3/4" (19.05mm), 7/8" (22.23mm),
1" (25.40mm), and 1 1/8" (28.58mm) body diameter and
in 25' (7.62m) and 30' (9.14m)
lengths, depending on grade.

All bars are straightened and Eddy Current (electro-magnetic)
inspected for surface defects.
Both ends are upset by automated high speed hot forging. Bars
are full length normalized to relieve residual stresses, air-quenched,
and tempered to refine and homogenize grain structure, and surface
shot-blasted to remove any remaining heat treat scale. An inhibitor-lubricant
is applied to each pin and thread protector installed. A rust
preventive coating protects Norris rods from atmospheric corrosion
in storage and corrosive downhole fluids on a short-term basis.
All rods are bundled according to API recommendations to prevent
handling damage during transportation to the well location.
Quality control inspections are performed at each step of the
manufacturing process, and by batch inspection after each process.
