Stainless steel pressure vessel tank

Stainless steel pressure vessel tank is an important equipment widely used in the industrial field. It is made of high-quality stainless steel material and has many advantages and functions.

Firstly, pressure vessel tanks have excellent corrosion resistance. Stainless steel is a metal material that is resistant to oxidation and corrosion, and can be used for a long time in harsh environments without damage. This makes pressure vessel tanks suitable for handling various corrosive media such as acids, alkalis, etc.

Secondly, pressure vessel tanks have high strength and stiffness. Stainless steel material has good mechanical properties and can withstand high pressures and loads, ensuring the safe operation of containers. In addition, the stiffness of stainless steel can effectively reduce the deformation and vibration of containers during transportation and use.

Thirdly, pressure vessel tanks have good sealing performance. Sealing is a key factor in ensuring that the medium inside the container does not leak. Stainless steel material has low permeability and high sealing performance, which can effectively prevent medium leakage and ensure the stability and safety of the process.

In addition, pressure vessel tanks also have high temperature resistance. Stainless steel materials still maintain good strength and stability under high temperature conditions, and can adapt to some high-temperature processes, such as chemical, petroleum and other fields.

Finally, pressure vessel tanks have a long service life and low maintenance costs. Due to the corrosion resistance and durability of stainless steel materials, pressure vessel tanks have a relatively long service life and do not require frequent maintenance and repair, reducing usage costs and downtime.

Definition of pressure vessel equipment:

The pressure vessel defined in the Regulations on the Safety Supervision of Special Equipment refers to a closed equipment that contains gas or liquid and carries a certain pressure. Its scope is defined as fixed and mobile containers for gases, liquefied gases, and liquids with a working pressure greater than or equal to 0.1 MPa (gauge pressure, and a product of pressure and volume greater than or equal to 2.5 MPa · L) and a working temperature greater than or equal to the standard boiling point; Gas cylinders containing gases with a nominal working pressure greater than or equal to 0.2 MPa (gauge pressure) and a product of pressure and volume greater than or equal to 1.0 MPa · L, liquefied gases, and liquids with a standard boiling point equal to or lower than 60 ℃; Oxygen chambers, etc. There is also a definition in the "Regulations on Safety Supervision of Pressure Vessels", which is similar to the "Regulations" and is subject to the "Regulations". The unit of MPa · L in the Regulations on the Safety Supervision of Special Equipment is L, which is cubic decimeters. Calculate the volume of the container and the volume of the jacket. The pressure is the vapor pressure. You can calculate it yourself to see if it counts as a pressure vessel adjusted by the regulations.

In order to distinguish it from general containers (atmospheric pressure containers), only containers that meet the following three conditions simultaneously are called pressure vessel equipment:

(1) The working pressure (Note 1) is greater than or equal to 0.1Mpa (the working pressure refers to the pressure that the top of the pressure vessel may reach under normal working conditions (gauge pressure); (Excluding hydrostatic pressure)

(2) The inner diameter (non-circular cross-section refers to its size) is greater than or equal to 0.15m. The volume (V) is greater than or equal to 0.025 cubic meters, and the product of working pressure and volume is greater than or equal to 2.5MPa-L (volume refers to the geometric volume of the pressure vessel);

(3) The medium used is gas, liquefied gas, and liquid with a working temperature higher than or equal to its standard boiling point
