Is the gas can a special equipment
The gas valve is a special equipment. Gas gate valves installed on all dirty gas, clean gas pipeline in the CCTV equipment, mainly used for metallurgy, coke, coal gas, chemical companies such as open/close control of gas pipeline. Gas for wedge gate valve gate double ram wedge gate valve for sealing surface machining accuracy requirements is low, easy to seal, the temperature change is not easy to cause the card housing and bruises, convenient maintenance after sealing surface wear, but the structure is more complex, parts, valve size and weight is bigger.
The catalog of special equipment is such regulations: all nominal working pressure is greater than or equal to 0.2 MPa (table), and the product of the pressure and volume greater than or equal to 1.0 MPa, L standard of gas, liquefied gas, and the boiling point is equal to or lower than 60 ℃ liquid cylinders; Oxygen tank. According to the above regulations, it is shown that the domestic gas tank belongs to the cylinder and is in accordance with the above regulations, so it is a special equipment and requires inspection.
One: a gas can is a special equipment. Normal gas tank pressure is about 0.6 MPa, which is about 50L, and 0.6 * 50 is greater than 2.5 MPa. 2: in the special equipment, pressure vessel scope are defined as follows: its range for maximum working pressure is greater than or equal to 0.1 MPa (table), and the product of the pressure and volume of greater than or equal to 2.5 MPa l. gas, liquefied gas and the highest standard of working temperature is higher than or equal to the boiling point of the mobile and stationary containers of liquid container; All nominal working pressure is greater than or equal to 0.2 MPa pressure (table), and the product of the pressure and volume greater than or equal to 1.0 MPa, L standard of gas, liquefied gas, and the boiling point is equal to or lower than 60 ℃ liquid cylinders.
