Cu-OilTool-Joint (Petroleum Drilling Tool Joint, Beryllium Copper
Alloy C17200)
Product Overview
The Cu-OilTool-Joint is a high-performance joint for petroleum
drilling tools, manufactured from Beryllium Copper Alloy C17200.
This alloy is widely used in the oil and gas industry due to its
high strength, corrosion resistance, hydrogen sulfide (H₂S)
resistance, and excellent machinability.
Material Properties
Material Composition: Beryllium Copper Alloy C17200, containing
1.8% - 2.0% beryllium, along with small amounts of cobalt and
nickel.
High Strength: Tensile strength ranges from 1130 - 1520 MPa, 0.2%
yield strength is 890 - 1380 MPa, and hardness ranges from 340 -
450 HV.
Corrosion Resistance: Excellent resistance to seawater,
non-oxidizing acids, dilute alkalis, and organic solutions, in
compliance with NACE MR0175 standards for H₂S environments.
Anti-galling and Wear Resistance: Demonstrates excellent
anti-galling properties against itself and other materials under
high load conditions, and good wear resistance even with
insufficient lubrication.
Non-magnetic: The alloy has a very low magnetic permeability
(<1.001), making it suitable for applications requiring
non-magnetic materials.
Applications
Petroleum Drilling: Used for manufacturing drill pipe joints, drill
collars, and other drilling tool connections, capable of
withstanding high pressures and high torque.
Oil and Gas Extraction: Suitable for various tools and equipment in
oil and gas wells, such as drill collars, drill pipes, drill bits,
and measurement tools.
Marine Engineering: Due to its corrosion resistance, it is also
applicable to oil and gas equipment in marine environments.
Machining and Forming
Machinability: C17200 alloy has excellent machinability, suitable
for turning, milling, drilling, and other machining processes.
Heat Treatment: Strength and hardness can be further enhanced
through cold working and heat treatment.
Weldability: The alloy has good weldability, suitable for arc
welding, brazing, and other processes.
Product Forms
The Cu-OilTool-Joint can be provided in various forms, including:
Bars: Starting from
海洋工程:由于其耐腐蚀性,它也适用于海洋环境中的石油和天然气设备.
