R&d and manufacturing technology of seamless e

Seamless elbow is an important pipe connection, widely used in petroleum, chemical industry, electric power, metallurgy, shipbuilding, aerospace and other fields. The development of its R&D and manufacturing technology is of great significance for improving the reliability and efficiency of pipeline connections. This paper will focus on the research and development and manufacturing technology of seamless elbow in order to provide reference for researchers and practitioners in related fields.

First, the concept and application field of seamless elbow

A seamless elbow is a pipe connector used to connect pipes in different directions or to connect pipes to equipment. It has a seamless structure and can withstand the working environment under harsh conditions such as high pressure, high temperature and corrosion, and is widely used in petroleum, chemical industry, electric power, metallurgy, shipbuilding, aerospace and other fields. The main function of the seamless elbow is to change the flow direction of the pipeline, make the pipeline layout more reasonable, reduce the resistance of the pipeline system, and improve the efficiency of fluid transportation.

Second, the manufacturing process of seamless elbow

1. Material selection: Seamless elbows are usually made of carbon steel, alloy steel, stainless steel and other materials, and suitable materials are selected according to the requirements of the working environment.

2. Elbow forming: The forming of se
