Manufacturing Process:
1. Rod Bar
The incoming rod bars are inspected for any damage, fault and
discontinuities. Before arranging the rod bars for production
process, carry out chemical composition testing, dimensional
inspection & surface quality inspection. High quality
standard is maintained at various stage inspections.
Chemical Composition: See below
table.
2.Manufacturing
Rod bars are manufactured from hot rolled alloy steel. Rod bars
are machine straightened and cold drawn to the required size. The
rod bar ends are hot forged according to API designed sizes. The
rods are then heat treated over the full length.As per
requirement of mechanical properties, the rods are normalized and
tempered to the specified level or quenched and tempered to the
required hardness and strength. Care is taken to achieve
metallographic structure with no residual stresses in the rod.A
sample specimen is cut from the heat treated material and is
tested for ultimate tensile strength, yield strength and
elongation. The rod is then again checked for straightness. The
forged ends are properly aligned with its body. Rods are cleaned
by shot-blasting to remove any scale and oxidation. The forged
ends are machined on C.N.C. Lathe machines as per API dimensions
and checked with API approved gauges.
Mechanical Properties: See below
table.
3. Packaging and Storage
The sucker rods are then coated with rust inhibitors and
carefully palletized in bundles for safe transport and
handling.
