Seamless elbow for technical communication

Seamless elbow is a common and important pipe connection, which is widely used in various industrial fields. It can connect the pipeline along the curve direction to realize the bending and turning of the pipeline, so as to meet the layout requirements of complex pipeline systems. This paper will introduce the related knowledge and application of seamless elbow from the perspective of technical communication.

First, the basic principle of seamless elbow

Seamless elbows are made by bending the pipe along a specific curve. The basic principle is to make use of the plastic deformation property of the pipeline, through the action of external force to make the pipe plastic deformation, so as to achieve the bending of the pipeline. In order to ensure the bending quality and connection reliability of the pipeline, it is necessary to control the bending Angle, bending radius and bending direction.

Second, the manufacturing process of seamless elbow

The manufacturing process of seamless elbow mainly includes cold bending and hot bending. Cold bending refers to the bending of the pipe at room temperature, which is suitable for some pipes with small diameters and thin walls. Hot bending is the use of high temperature heating, so that the pipe becomes soft after bending, suitable for some large diameter and thick wall of the pipe. In the manufacturing process, the appropriate process needs to be selected according to different pipe materials and requirements.
