About the reinforced plastic fiberglass sucker rod
By resin and glass fiber reinforced plastic fiberglass sucker rod according to certain proportion, made by pultrusion and curing.
The advantages of the reinforced plastic fiberglass sucker rod:
1. Light quality: Unit weight of the whole rod is approximately a third of the steel rod.
2. Good elasticity: Can be achieved of subsurface pump plunger stroke, achieve the purpose of production.
3. Corrosion resistance: Joint part is 20 CrMo steel, rod body without corrosion phenomenon in CO2 and H2S.
4. High strength: D level performance can be achieved, the maximum pressure can reach 300 Mpa.
5. Good paraffin effect: Outer layer is the resin, surface smooth, not easy to knot wax
About the steel sucker rod
Grade C Sucker Rod: It is designed for light or moderate loads in the non-corrosion medium, it is not susceptible to sulphuric stress cracking.
Grade D Sucker Rod: It is designed for moderate to high loads in the non-corrosion or light--corrosion medium.
Grade H Sucker Rod: It is the high strength sucker rod. It is designed for moderate to high loads in the corrosion medium. Compared with Grade D
Sucker Rod, it has higher tensile strength, surface hardness and surface residual compress stress.
