Product Application of Polished RodThe polished rod is a durable and high-quality product manufactured
from high tensile strength alloy steel. It is designed for
longevity and reliability, with a smooth surface that promotes
efficient operation. The production of polished rods complies with
API Spec 11B standards to ensure consistency and adherence to
industry regulations. There are two main types of polished rods available: regular grade
D polished rods and end upsetting polished rods. Regular grade D
polished rods are connected using polished rod couplings, while end
upsetting polished rods are directly connected to sucker rods for
specific applications. Another type of polished rod available is the ultra-high tensile
strength and corrosion-resistant variant. These polished rods are
made of 20CrMo alloy steel and undergo heat treatment through
quenching and tempering. The rod surface is further enhanced with a
nickel-based alloy (Ni35) coating, providing superior resistance to
corrosion and wear. Specifications:
- Material: 20CrMo alloy steel, stainless steel rod
- Types: Regular polished rod, end upsetting polished rod
- Rod diameters: 1", 1-1/8", 1-1/4", 1-1/2"
- Lengths: 25', 26', and 30', with customization options available
for other specifications.
