Will the degree of zero is ultra-low temperature, cold storage is a special equipment?
Cold storage is made up of special equipment.
From liquid ammonia tank (bottle), condenser, pressure pipe and so on.
The following is a list of special equipment catalogs for pressure vessels and pressure piping:
Pressure pipe, refers to the use of a certain pressure, for the delivery of gas or liquid tubular equipment, the scope of the provisions of the maximum working pressure greater than or equal to 0.1MPa (gauge pressure), the media for the gas, liquefied gas, steam or flammable, explosive , Toxic, corrosive, the highest operating temperature is higher than or equal to the standard boiling point of the liquid, and the nominal diameter greater than or equal to 50mm pipe. Nominal diameter less than 150mm, and its maximum working pressure of less than 1.6MPa (gauge pressure) of the non-toxic, non-flammable, non-corrosive gas pipeline and equipment, except for the body of the pipeline. Among them, the oil and gas pipeline safety supervision and management should also be in accordance with the "Safety Production Law", "Oil and Natural Gas Pipeline Protection Law" and other laws and regulations.
Pressure vessel, refers to the gas or liquid, carrying a certain pressure of the closed equipment, the scope of the provisions of the maximum working pressure greater than or equal to 0.1MPa (gauge pressure) of the gas, liquefied gas and the maximum operating temperature is higher than or equal to the standard boiling point of the liquid , A fixed container and a movable container having a volume greater than or equal to 30 L and an inner diameter (non-circular cross-section refers to a maximum geometric dimension within the cross-sectional boundary) greater than or equal to 150 mm; a nominal operating pressure greater than or equal to 0.2 MPa (gauge) The product of pressure and volume is greater than or equal to 1.0MPa ? L of gas, liquefied gas and standard boiling point is equal to or below 60 ℃ liquid cylinders;
