High-performance gap elbow

Abstract

The invention discloses a high-performance gap elbow. The high-performance gap elbow comprises a first joint and a second joint; the first joint and the second joint are connected through a bending pipe; the bending pipe is a multilayer structure consisting of a titanium pipe, a copper pipe and a carbon steel pipe in sequence from inside to outside; the titanium pipe, the copper pipe and the carbon steel pipe are fused with each other; the pipe wall of the copper pipe is a composite casting structure; multiple stainless steel ribs are arranged in the pipe wall of the copper pipe in the radial direction of the pipe body; the stainless steel ribs are distributed by center symmetry with the center shaft of the copper pipe as center; and the ratio of the diameters of the stainless steel ribs to the thickness of the copper pipe is 1: 2. The high-performance gap elbow is mainly formed by fusing three layers of pipes, wherein the copper pipe in middle is not a homogeneous metal pipe; multiple stainless steel ribs are fused in the pipe wall of the copper pipe through a composite casting mode; the stainless steel ribs greatly improve the mechanical performance and the toughness of the whole elbow bending part; and even if a larger angle is bent, the breakage is not easy to generate.

Description

technical field [0001] The present invention relates to an elbow, more precisely, a high performance seamed elbow. Background technique [0002] Elbows are fittings that change the direction of a pipeline. According to the angle, there are three most commonly used ones: 45° and 90°180°, and other abnormal angle elbows such as 60° are also included according to engineering needs. Elbow materials include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. The ways to connect with the pipe include: direct welding, flange connection, hot-melt connection, electric fusion connection, thread connection and socket connection, etc. According to the production process, it can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow, etc. Because the elbow is bent during processing, the mechanical strength and toughness of the bent part are weaker than other parts, and accidents of fractu...

AI Technical Summary

Problems solved by technology

Due to the bending treatment of the elbow during processing, the mechanical strength and toughness of the bending part are weaker than other parts, and accidents of fracture are more likely to occur
