Elbow with petal-shaped structure

Abstract

The bent pipe with the petal-shaped structure comprises the bent pipe body, the petal-shaped hole section is formed in the position of the inlet end or the position close to the inlet end through the circulation channel, and the petal-shaped hole section is defined by the four semicircular inner walls jointly, so that the anti-erosion characteristic of the bent pipe body is optimized, and the bent pipe has the beneficial effects that the technical difficulty is small, and the cost is low. The manufacturing process is simple, and the cost is low.

Description

technical field [0001] The invention relates to the field of gas-solid two-phase flow conveying pipes, in particular to an elbow with a petal-shaped structure. Background technique [0002] Erosion is the process of surface wear and damage caused by particles carried in the fluid hitting the surface at high speed. Erosion will bring major problems to the transportation industry such as oil and natural gas, resulting in thinning of the wall of the elbow or even leakage of oil or natural gas due to damage, which will affect the safe operation of the equipment. As a component that changes the flow direction, the elbow is more likely to fail due to erosion. Studies have shown that the degree of erosion damage at the elbow of the conveying pipeline is about 50 times that of the straight pipe. Erosion damage not only wastes materials, consumes energy, and reduces equipment efficiency, but also accelerates equipment failure and reduces equipment service life, resulting in greater...

AI Technical Summary

Problems solved by technology

Erosion damage not only wastes materials, consumes energy, reduces equipment efficiency, but also accelerates equipment failure and reduces the service life of equipment, thereby causing greater economic losses

[0003] At present, the methods of improving erosion mainly include using composite materials, surface coating, surface modification and other methods to improve the erosion resistance of elbow pipes. This method can reduce erosion to a certain extent, but it is difficult to manufacture and high in cost. Not conducive to green energy
