Product instruction

Sucker rods are manufactured according to API 11B Specifications. Currently, we market 3 types of API sucker rods Grade D Alloy and Grade D Special which are formulated from different alloys:AISI 4130 (Grade D), AISI 4142 (Grade D) and AISI 4720 (Grade KD).
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.

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.
