The Pressure Vessel Has A Wider Operating Temperature Range
Aug 22, 2017

With the development of chemical and petrochemical industries, the working temperature range of pressure vessels is becoming wider and wider, and the capacity is increasing. Some require resistance to medium corrosion. Since the 1960s, the development of nuclear power plants has put forward higher safety and technical requirements for reactor pressure vessels, thus promoting the further development of pressure vessels and widely used in various industrial sectors. The pressure vessel is predominantly cylindrical and has a spherical or other shape. According to the structure, can be divided into multi-layer pressure vessel, around the plate pressure vessel, Pressure Vessel and Pressure Pipe Component groove around the belt pressure vessel, hot sleeve pressure vessel, forging pressure vessel and thick plate welded pressure vessel. Most of the pressure vessels are made of steel, and some made of non-metallic materials such as aluminum, titanium and other non-ferrous metals and FRP, prestressed concrete and other non-metallic materials. The use of pressure vessels in the event of an explosion can cause catastrophic accidents. In order to ensure the safety of the container under the premise of ensuring the design of advanced, reasonable structure, easy to manufacture, the use of reliable and cost economy and other purposes, countries have developed according to their own specific conditions, Pressure Vessel and Pressure Pipe Component the pressure vessel standards, norms and technical conditions, Pressure Vessel and Pressure Pipe Component the pressure vessel The design, manufacture, inspection and use of specific and must comply with the provisions.

The use of pressure vessels is very extensive. It is in the petrochemical industry, energy industry, scientific research and military and other national economic departments have played an important role in the equipment.

The pressure vessel is usually composed of cylinder body, head, flange, sealing element, opening and takeover, bearing and other six parts constitute the container body. In addition, Pressure Vessel and Pressure Pipe Component it is equipped with safety devices, meters and the completion of the role of different production processes.

Pressure vessels due to sealing, pressure and media and other reasons, prone to explosion, burning fire and endanger the safety of personnel, equipment and property and pollution of the environment. At present, all countries in the world as an important monitoring products, designated by the state specialized agencies, Pressure Vessel and Pressure Pipe Component in accordance with national regulations and standards of supervision and inspection and technical inspection.

2. Classification

There are many ways to classify pressure vessels, and are classified from the point of view of use, manufacture and monitoring.

(1) according to the level of pressure is divided into: low pressure vessels, Pressure Vessel and Pressure Pipe Component medium pressure vessels, Pressure Vessel and Pressure Pipe Component high pressure vessels and ultra high pressure vessels.

(2) according to the media is divided into: non-flammable, non-toxic; flammable or toxic; highly toxic.

(3) according to the role of the process is divided into:

① reaction container: used to complete the physical and chemical reaction of the container.

② heat exchange container: used to complete the heat exchange of media containers.

③ separation containers: used to complete the quality of the media exchange, Pressure Vessel and Pressure Pipe Component gas purification, solid, liquid, gas separation containers.

④ storage and transportation containers: for the possession of liquid or gas materials, storage media or the balance of the role of the buffer buffer.
