Gas cylinder unit

Technical specifications for gas cylinders and gas units

In the field of compressed gas applications, cylinder gas units refer to various use scenarios where high-pressure cylinders are used as the main source of gas supply. In order to ensure the safety and efficiency of gas use, relevant operations must follow the following technical specifications:

1. Classification of application scenarios

1. field of industrial production

• Metal processing processes such as welding and cutting
• Pneumatic tools power supply
• Chemical raw material gas storage and transportation

2. public service areas

• Medical institution oxygen supply system
• Fire-fighting equipment gas storage device
• Laboratory specialty gas storage

3. Commercial service scenarios

• Car repair tire inflation services
• Food packaging nitrogen filling system
• Diving sports breathing gas supply

2. Gas metering method

1. pressure measurement
   The pressure of the remaining gas in the cylinder is displayed by a pressure gauge, and is converted into the actual usage volume combined with the gas state equation. Pay attention to the impact of temperature changes on pressure readings.

2. mass flow method
   Equipment such as Coriolis mass flow meters are used to directly measure gas mass consumption, which is suitable for high-precision measurement demand scenarios.

3. volume conversion method
   Calculate the theoretically available gas volume based on the nominal volume and filling pressure of the cylinder. Gas compression coefficient and temperature compensation factors need to be considered.

3. Safety operation specifications

1. storage management

• Gas cylinders should be stored vertically in a ventilated and dry place away from heat sources and corrosive substances
• Empty and full bottles need to be managed in different areas and wear obvious status signs

2. use requirements

• Connecting pipes require metal hoses that meet pressure levels
• Check the integrity of seals before operation, and use under excessive pressure is strictly prohibited
• The work site is equipped with gas detection and alarm devices

3. emergency treatment

• Close the main valve immediately and vent when a leak is detected
• Prohibition of using open flames to detect leak points
• Conduct and record emergency drills regularly

4. Management recommendations

1. Establish a cylinder usage ledger to record key data such as filling date and pressure changes
2. Conduct quarterly air cylinder appearance inspection and valve tightness test
3. Sign standardized service agreements with qualified gas suppliers

This specification applies to the use and management of conventional compressed gas cylinders, and special gases (such as flammable and toxic gases) need to be implemented with reference to special safety standards.
