Product Application of Polished Rod
Polished rods are primarily used in the oil and gas industry for connecting sucker rods to the pump unit. They play a crucial role in the operation of pumping systems by transmitting the reciprocating motion from the sucker rod to the pump, enabling the extraction of fluids from the well.
Manufacturing Specification: API 11B
Material:
- Chemical Composition: The chemical composition of polished rods can vary depending on the specific requirements and manufacturers. Typically, they are made from AISI recommended series steels that adhere to certain chemical and mechanical property requirements.
a) Carbon Steel: AISI 1035-1050
b) Stainless Steel: AISI 304/316 or 431
c) Alloy Steel:
- AISI 4120-4140
- AISI 4315-4340
- AISI 4615-4625
- AISI 8620-8630
It's important to note that the chemical composition and limits of the polished rods are detailed in the manufacturer's material specifications. Polished rod liners, if applicable, should adhere to the specified chemical composition and may be required to have a sprayed metal coating.
Mechanical Properties for Finished Product:
The mechanical properties of polished rods are essential for ensuring their strength and durability. The ultimate tensile strength requirements vary depending on the material used.
a) Carbon Steels: The ultimate tensile strength should be within the range of 90,000 psi to 160,000 psi (621 MPa to 1,103 MPa).
b) Alloy Steels: The ultimate tensile strength should be within the range of 95,000 psi to 160,000 psi (655 MPa to 1,103 MPa).
c) Stainless Steels: The minimum ultimate tensile strength should be 70,000 psi (482 MPa) for AISI 304/316 and 90,000 psi (620 MPa) for AISI 431.
These mechanical property requirements ensure that the polished rods can withstand the high loads and pressures encountered during oil and gas production operations.
Please note that the specific manufacturing specifications and material requirements may vary among different manufacturers. It is important to consult the manufacturer's documentation and product specifications for precise information when considering the application of polished rods.
