Right Angle High Vacuum Valve (GD Series)

A pressure vessel is a closed container capable of withstanding internal or external gas or liquid pressure. This type of equipment is widely used in various industrial fields such as chemical, petroleum, pharmaceutical, and food processing, for storing, transporting, or processing various media. According to their different purposes and design characteristics, pressure vessels can be divided into various types, such as reactors, heat exchangers, separators, etc.

 

 

 

###The main components of a pressure vessel

 

 

 

-Shell: The part that constitutes the main body of a pressure vessel, usually welded from steel plates.

 

-Head: Connected at both ends of the shell, used to seal the container. Common forms include hemispherical, elliptical, and flat plate shapes.

 

-* * Takeover * *: Installed on the shell, used to connect pipelines or other equipment to achieve input and output of media.

 

-* * Support * *: Support the entire weight of the container and secure it to the foundation.

 

-* * Safety attachments * *: including but not limited to safety valves, bursting disc devices, etc., used to ensure the safety of personnel and equipment during operation.

 

 

 

###Design and Manufacturing Standards

 

 

 

In order to ensure the safe and reliable operation of pressure vessels, various countries have formulated strict design and manufacturing specifications and technical requirements. For example, in China, the design, manufacturing, installation, and use of pressure vessels need to comply with the "Regulations on Safety Supervision of Special Equipment" and relevant national standards; Internationally, a series of specifications developed by ASME (American Society of Mechanical Engineers) are widely used.

 

 

 

###Security considerations

 

 

 

Due to the fact that pressure vessels often carry media under high pressure or high temperature conditions, their safety is crucial. In addition to using high-strength materials for manufacturing, regular non-destructive testing (such as ultrasonic testing, magnetic particle testing, etc.) is also required to check for cracks, corrosion, and other issues. At the same time, correctly setting and maintaining safety attachments is also one of the effective measures to prevent accidents from occurring.

 

 

 

In short, pressure vessels are one of the indispensable and important equipment in modern industry, but at the same time, they also have extremely high requirements for design and manufacturing due to their special working environment. Proper selection, rational use, and regular maintenance are of great significance for ensuring its long-term stable operation.
