Problems solved by technology

However, due to the influence of various factors, it will also cause corrosion of the copper-nickel alloy tube of the condenser, which has become a prominent problem of whether the power plant can operate safely and economically.
In recent years, corrosion and leakage accidents of copper-nickel alloy pipes have occurred in some power plants, causing major economic losses. In power plants, once copper pipes leak and corrode, the method of shutting down and replacing copper pipes is often used. This method is caused by the replacement of copper pipe materials. Certain direct economic losses, especially power generation losses caused by downtime will be extremely huge. Sudden shutdown may even cause power grid paralysis, which will have a huge impact on society

Abstract

The invention discloses a corrosion resistant copper-nickel alloy. The corrosion resistant copper-nickel alloy comprises the following raw material components of, by weight, 55-68 parts of Ni, 20-30 parts of Cu, 0.5-1.5 parts of Fe, 0.05-0.3 part of C, 0.25-1.6 parts of Si, 0.3-1 part of Mn, 0.3-1 part of Ti and 0.5-2.5 parts of Al. The copper-nickel alloy is good in corrosion resistant effect, strong in anti-cavitation and electrochemical corrosion capacity, meanwhile quite high in strength and toughness and high in tensile strength.

Description

technical field [0001] The invention relates to the technical field of alloy materials, in particular to a corrosion-resistant copper-nickel alloy. Background technique [0002] Copper-nickel alloys have been widely used in the national economy (such as electric power, marine, etc.) in recent years because of their excellent electrical conductivity, thermal conductivity, corrosion resistance, and easy processing and molding. The condenser, which is an important part of the generator set, mostly uses brass tubes or white copper tubes (copper-nickel alloys) for its tubes. In general, copper-nickel alloys are used more because of their better corrosion resistance. However, due to the influence of various factors, it will also cause corrosion of the copper-nickel alloy tube of the condenser, which has become a prominent problem of whether the power plant can operate safely and economically. In recent years, corrosion and leakage accidents of copper-nickel alloy pipes have occu...
