Swaged nipple also known as reducing nipple, it is a pipe connection made by forging process. It is characterized in that the diameter of one or both ends gradually decreases to a smaller inner diameter to facilitate connection with other pipes of different diameters. It is usually made of high-quality metal materials such as carbon steel, alloy steel or stainless steel, with a specially designed tapered or arc-shaped reduction section inside, which can ensure good fluid flow characteristics and effective sealing between pipes. Reducer pipes are widely used in various industrial fields, especially in the following scenarios. High-pressure oil and gas: used to connect pipelines of different diameters to ensure smooth transmission of fluids. Chemical industry and electric power: In high-pressure and high-temperature environments, swaged nipple can provide stable connections to ensure safe operation of the system.
