Abstract

The invention discloses a titanium alloy tube for a heat exchanger. The titanium alloy tube material comprises the following components in percentage by weight: 3-5% of aluminum, 2.5-4.5% of vanadium, 0.2-0.8% of iron, 0.2-0.5% of nickel, 0.05-1% of carbon and the balance of titanium; and all the raw material components are fully mixed together, then the mixture is put into a vacuum melting furnace and is melted at a high temperature to prepare a titanium alloy ingot, then the titanium alloy ingot is subjected to hot rolling to prepare a titanium alloy rod blank, then the titanium alloy rod blank is sent into a perforator for cross piercing so as to obtain a titanium alloy tube, and finally the titanium alloy tube is sent into a sizing mill for sizing. Therefore, the titanium alloy tube disclosed by the invention is light in weight, good in surface quality, high in dimensional accuracy, simple in process and high in finished product percent of pass.

Description

technical field [0001] The invention relates to the field of titanium alloy tubes, in particular to a titanium alloy tube for heat exchangers. Background technique [0002] A heat exchanger is a device used to transfer heat from a hot fluid to a cold fluid to meet the specified process requirements.
