Elbow pipe with auxiliary connecting and fixing structure

Abstract

The invention discloses an elbow pipe with an auxiliary connecting and fixing structure. The elbow pipe with the auxiliary connecting and fixing structure comprises an elbow pipe body. The bending angle of the elbow pipe body is 90 degrees. The middle end position of a horizontal pipeline and the middle end position of a vertical pipeline of the elbow pipe body are provided with a first fixing ring and a second fixing ring correspondingly in a welded manner. The first fixing ring is provided with a first fixing base in a welded manner, and the second fixing ring is provided with a second fixing base in a welded manner. A supporting rod is welded between the first fixing ring and the second fixing ring. According to the elbow pipe with the auxiliary connecting and fixing structure, the elbow pipe body is fixedly provided with the first fixing base and the second base through the first fixing ring and the second fixing ring, the first fixing base and the second fixing base are used for fixing the elbow pipe body, by means of the arrangement of the first fixing base and the second fixing base, the fixation of the elbow pipe body is facilitated, the supporting rod is welded between thefirst fixing ring and the second fixing ring, the supporting rod can conduct auxiliary supporting on the elbow pipe body, the strength of the elbow pipe body is improved, and deformation damage of the elbow pipe body is prevented.

Description

technical field [0001] The invention relates to the technical field of bent pipes, in particular to a bent pipe with an auxiliary connection and fixing structure. Background technique [0002] The bent pipe is bent by a complete set of bending equipment, which is divided into two processes: cold simmering and hot pushing. No matter what kind of machinery and equipment and pipelines, most of them use elbows, mainly for oil, gas, liquid, engineering bridge construction, etc. Analysis of the main reasons for the decline in the quality of elbows and attention methods: 1. When bending, under the action of external force distance M, the outer arm wall of the neutral layer of the tube is thinned by tensile stress &1, and the inner side is subjected to compressive stress. Thickening due to the action, the resultant force N1 and N2 changes the cross-section of the tube. Based on this factor, the main reason for the decline in the quality of the elbow is RX and SX. Therefore, in GBJ...

AI Technical Summary

Problems solved by technology

[0003] However, there are some deficiencies in the use of the existing elbow. The existing elbow has a simple structure and does not have a fixed structure, which makes its fixing more troublesome. Secondly, the elbow and the pipeline connected to it lack an auxiliary limiting structure. As a result, the stability of its connection is low, so it cannot meet the needs of users
