China High-Performance Alloy Material Technology Company Creates Advanced Material Solutions for Extreme Pressure in Deep Sea Operations Hay:A03NBBW

The extreme pressure of deep-sea operations is a difficult problem that the offshore oil exploration industry must face. Especially for offshore drilling operations, the replacement cost of equipment components and materials is high, and there are high requirements for safe operation. Therefore, the selection has the characteristics of "high bearing capacity, high stability, and high strength", and meets the requirements of wear resistance, corrosion resistance, and ultra-long heavy-duty service. The longevity of the material is a top priority.

High wear-resistant series alloy

Based on the extreme pressure characteristics of deep-sea operations in the petrochemical industry, NBBW has developed high wear-resistant materials & application solutions for oil drilling, including 220, 230 and 350, based on the actual industry, through long-term technology accumulation and scenario application research. The demand for core materials in the oil exploration industry accelerates the breakthrough of core technologies for key equipment components in the industry, solves the problem of extreme pressure in deep-sea operations, and lays a solid material foundation for the development and utilization of deep-sea oil.

220 high-strength wear-resistant and corrosion-resistant aluminum bronze alloy


220 high-strength wear-resistant and corrosion-resistant aluminum-bronze alloy is used for pump bodies, valves, valve seats, guide rods, valve stems, bolts, nuts and other components for the Christmas tree of drilling platforms.


Its surface can form a dense alumina protective layer, which has good high temperature corrosion resistance and oxidation resistance, and also has excellent corrosion resistance in the atmosphere, fresh water and sea water.


At the same time, BearMet220 has the characteristics of being weldable, not easy to be brazed, and well processed under hot pressure.

230 seawater corrosion resistant nickel aluminum white copper alloy material


230 seawater corrosion-resistant nickel-aluminum-white-copper alloy materials are used in ROV, AUV and wellhead underwater sealing connectors, cabin connectors, subsea fasteners, pump shafts and valve shafts, valve stems, hydraulic pistons, drill pipes and fixtures and other fields .


The material has the characteristics of high mechanical strength, good wear resistance, low magnetic permeability, strong resistance to seawater corrosion, and can also achieve resistance to hydrogen embrittlement and stress cracking in seawater.


In addition, 230 also has good resistance to stress corrosion cracking and marine biofouling under the condition of hydrogen sulfide.

350 ultra-high wear-resistant and corrosion-resistant material


350 ultra-high wear-resistant and corrosion-resistant material is a copper alloy material with high strength, high toughness, excellent wear resistance and corrosion resistance. It has an ultra-high strength of 1400MPa and can adapt to harsh service conditions of wear and corrosion resistance. , The corrosion resistance in seawater or acid, oil and gas environment and the wear resistance under high load conditions are better than beryllium copper and aluminum bronze.



At the same time, the material has excellent fatigue strength, higher heavy-duty service life and reliability. Coupled with the non-magnetic and beryllium-free environmental protection characteristics, it is very competitive in the selection of materials for deep-sea drilling operations.


350 is widely used in MWD and LWD drilling tools for oil drilling, oil exploration well guide rods, stone pump components, exploration well probes, deep-sea explosion-proof, separable connecting valves and other oil high temperature resistant, wear-resistant, non-magnetic, high-strength copper alloy components .
