A steel sucker rod is one of the important equipment of oil
field.Can provide seven kinds of the level of sucker rod,including
C, K, D, KD, HL, HY and KH.C, K, D sucker rod press design and
manufacture standard of API Spec 11 B, KD, HL, HY grade rod design
and manufacture according to standard SY/T5029-2006, KH level rod
according to standard within the company.
C grade sucker rod series - is mainly used for light, medium load,
no corrosion or corrosion shallow Wells or in deep well pumping,
material is carbon steel or manganese steel.
Grade D sucker rod is made of high quality alloy steel, after heat
treatment with high strength, plasticity is good, long life and
other characteristics, it is suitable for light when there is no
corrosion or corrosive medium in the deep Wells under the
environment of use.
HL, HY grade rod is made of high quality alloy steel manufacturing,
have the characteristics of ultra high strength, used in deep well,
big strong pump used in production.
And K, KD and KH level of sucker rod with different content of Ni
Cr - Ni - Mo high quality alloy steel manufacturing, have
anticorrosive, resistance to corrosion function, respectively
applicable to strong corrosion of shallow, middle and deep Wells.
