Abstract

The application relates to a manufacturing method of a connecting pipe and the connecting pipe for a pressure-equalizing water mixing tank, and aims to solve the problems of insufficient structural strength and poor corrosion resistance of a traditional connecting pipe under high-pressure working conditions of a heating system. The connecting pipe has high strength and high corrosion resistance by using an alloy steel material with specific chemical components, combining optimized process steps of hot forging and preforming, precision investment casting, deburring and polishing, inert gas protection welding and passivation treatment, and has excellent mechanical strength and corrosion resistance.
