API 11B Oil Production Tools Sucker Rod From China Supplier With Factory Price
API 11B Oil Production Tools Sucker Rod from China Supplier with factory price
1) Material: Alloy Steel
2) Grade: D
3) Standard: API 11B
4) API and ISO certified
5) Description
The sucker rod is a steel rod that used to transfer the movement and power of pumping unit to the downhole pump.
The product conforms to API Specification 11B (Oil extraction rod Standard) and other related standard, authorized to use the API monogram.
All sizes of sucker rod (standard, heavy, polish rod) which conform to API specification latest version 11B are available in grade K, C, D and HL.
Sucker Rod adopts ultra audio induction quenching technology to further process from the Grade D sucker rod. The metallographic structure is acicular martensite; the crystalline grain is fine and even. After shot- blasting, the rod has higher tensile strength (980~1200 MPa), surface hardness (HRC≥42) and surface residual compress stress (≤-200MPa). Also the rods provide with higher fatigue strength.
The unique of the ultra high strength sucker rod is that the rod has a thin compression layer 10-15% at the rod surface that remains under compression even under normal operating tensile loads.
6) Advantage
a. Increase the effective stroke of the plunger, improve pump efficiency and increase oil production.
b. Reduce the number of workover and wash well to avoid hypercoagulable, high wax plugging wells wells, dead wells and other accidents.
c. Reasonable structure, reliable sealing.
d. Mechanical performance to the level of D-level bar.
