API KD Grade Sucker Rod for Oil Drilling with Coupling
API 11B Standard Sucker Rod Oil Drilling Equipment And Sucker Rod Accessories
Products Description:
Sucker rod is the common equipment in the oil extraction. It is manufactured through many process including the testing, straightening and forging. The sucker rod is placed between the polished rod and oil well pump. To deliver power. Sucker rod is manufactured from high quality carbon steel and alloy steel, which is conform to the API Spec 11B standard. Sucker rod has various types including the common sucker rod, hollow sucker rod and FRP sucker rod. Commonly we use the sucker rod coupling to connect the sucker rod. The sucker rod also has various specs to fit different environments and applications.
Features:
1. Sucker rod structure can be injected with hot oil, vapor. It can also be used for running heating cable.
2. The threaded joint is designed with bearing surface to make the joint more reliable.
3. High rigidity to bear large torque.
4. Connection type: coupling connection and direct connection.
5. Metal pallet package for saving space and convenient to transport.
6. There are plastic caps to protect thread of sucker rod.
Grade Detail:
1. Grade D sucker rod: Made of quality heat treated steel alloy, with high tensile and yield strength; suitable for non-corroding or mildly corroding environment.
2. Grade C sucker rod: Moderate strength, not susceptible to sulfide stress cracking, suitable in sour medium.
3.. Grade HL and HY sucker rod: High strength; structure and size matching with grade D sucker rod; withstanding 966-1, 136 MPa (140, 000-164, 720 psi); suitable for deep and large displacement wells
