Epoxy resin sucker rod
1.Advantage: High strength, Larger torque, high resistance to fatigue and corrosion,
Long service life.
2.Process: Grade D sucker rod → Supersonic frequency processing → Strengthen
shot blasting →Electrostatic spraying.
1) Supersonic frequency processing is based on the grade D sucker rod process, is
made of supersonic quenching process, make its surface to form a layer of 5% ~ 13%
of the hardening layer, the microstructure is plate strip martensite, compressive stress
on the surface of 300-500 mpa, raised the tensile strength, torsional strength and
fatigue strength of the rod body.
2) Strengthen blasting treatment is to remove the surface micro defects, oil, dust, rust
on the surface of the body, and a layer of compressive stress in rod surface, and can
increase the coating layer adhesion, to form micro blast strengthening layer.
3) Electrostatic spraying, spraying the modified epoxy powder evenly onto the surface
of the rod, using electrostatic adsorption principle, spray a layer of powder evenly on
the surface of the rod. The surface powder of the rod is heated to the specified
temperature and the corresponding time is kept, so that it can be melted, smoothed
and solidified to obtain the surface effect of the rod we want. The sucker rod spray
layer adopts corrosion resistant modified epoxy resin material,enveloped and fuse to
the outside of the rod body. The material has excellent resistance to hydrogen sulfide,
carbon dioxide, and salt and other corrosive material in the oil and gas, and pore
defects such as hot coating layer does not exist a whole, fusion in the form of a whole
enveloped to avoid the rod body contact with the fluid, so as to achieve the purpose of
the corrosion.
3.Attention, such as use in horizontal well or high-inclination well, because the
corrosion resistant layer is not wear-resistant, should be used after the moulding
guides, the effect can replace the anti-corrosion sucker rod. Using the temperature
below 180 ºC.
4. Cost performance
The high-strength and long-life with anticorrosion sucker rod is 1.2 times the price of
grade D sucker rod. It is 0.5 times the price of AISI4330 material type anticorrosion
sucker rod. This kind of sucker rod has an inner flexible and outer tenacity features,
service life is 2 times than the grade D sucker rod and material type anti-corrosion
sucker rod , can also be used in small size instead of large size rod, such as 7/8 "rod
can be used instead of 1" rod, will save the purchasing cost and pump hanging weight,
save a space again, and increased the quantity of oil.
