Failure Analysis of Burst of High Pressure Steel Cylinder

High Pressure Steel Bottle Failure Analysis

High pressure steel bottles are widely used in industrial applications due to their high pressure capacity. It is important to understand the potential causes of its failure in order to maximize its performance. In this paper, the failure modes of high pressure steel bottles will be discussed and an analysis of the possible causes of these failures will be provided.

The first type of failure associated with high pressure steel bottles is corrosion. This can occur due to improper storage conditions or contact with aggressive chemicals. Presence of water and salts in the environment can also lead to corrosion. Corrosion of the bottle can cause leaks and the failure of other parts of the bottle due to corrosion-related effects. In order to minimize the risk of corrosion, it is important to ensure that the bottles are stored in dry, clean and suitable environments.

The second type of failure associated with high pressure steel bottles is fatigue failure. This type of failure occurs when a material is subjected to cyclic loading. The cycle of load and unload creates stress and strain concentrates resulting in localized fatigue fracture. The most common cause of fatigue fracture is the use of wrong material or incorrect design. In order to prevent fatigue fracture, it is important to ensure that the bottle is constructed of the correct material and the design is optimized to the application.

The third type of failure associated with high pressure steel bottles is thermal failure. This type of failure can occur due to elevated temperatures around the bottle. If the temperature around the bottle is too high, it can cause the steel to become brittle, resulting in cracking and failure. In order to minimize the risk of thermal failure, it is important to ensure that the environment surrounding the bottle is temperature-controlled.

The fourth type of failure is related to mechanical defects of the bottle. This can include the presence of microscopic cracks and flaws, which can result in premature failure of the bottle. It is important to inspect the bottle for these defects before use in order to ensure reliable performance.

In summary, high pressure steel bottles can fail due to corrosion, fatigue, thermal and mechanical defects. It is important to understand these different failure modes and the possible causes in order to maximize the performance of the bottle. It is also important to inspect the bottle for any defects before use and ensure that it is stored in the correct environment. By properly inspecting, storing and using the bottle, the risk of failure can be minimized.

High-pressure steel cylinder explosion malfunction is one of the common industrial accidents. Generally, the bursting of high-pressure steel cylinders is caused by overload, which leads to local concentrated plastic deformation on the wall at the extreme point, resulting in a large increase in internal stress and eventual failure.

At the same time, outside the cylinder can be divided into high and low pressure parts, when the high pressure part of the wall in terms of plastic to a certain extent, high pressure gas in the cylinder can no longer be confined, so it is explosive. It can be seen that welding, tempering and other factors that affect the mechanical properties of the high pressure steel cylinder wall need to be paid attention to in the production process.

In view of the cause of the high-pressure steel cylinder explosion, we should pay attention to strengthening the inspection of all components during the manufact
