Introduction

Analysis of the core content of the standard

Technical dimensions	HG 2823 requirements	GB 325 benchmark	Differences
Structural design	Triple round curling + reinforcement ring	Double curling	Sealing level increased by 30%
Airtightness test	80kPa (type inspection)	50kPa	Pressure resistance index increased by 60%
Coating thickness	≥0.020mm	No clear requirements	New special requirements for anti-corrosion

Details of key technical requirements

4.1 Structural specifications

Steel drums must be made of whole steel plates, and the barrel body welding is limited to the use of resistance welding technology. Structural requirements:

Two external convex ring ribs or 5-7 corrugations for reinforcement
19±1mm reinforcement rings are set on the top/bottom of the barrel
The distance between the spiral injection port and the air vent is 1415±4mm

4.2 Performance indicators

Typical application case: A chemical plant used steel barrels of this standard to contain CFC-11. After a 1.8m drop test, there was no leakage in the barrel and the deformation of the ring ribs was <3%, which fully met the safe transportation requirements for ozone-depleting substances.

Key points for the implementation of the standard

Quality control system

Establish a three-level unqualified classification mechanism according to GB 2828:

Class A defects: directly affect the sealing (such as weld quality)
Class B defects: dimensional deviation (ring rib height deviation> 2mm)
Class C defects: appearance defects (coating sagging)

Inspection process optimization

Suggestions for manufacturers:

The first piece of each shift must be inspected for air tightness (50kPa)
Sampling 3 pieces per month for 80kPa enhanced inspection
Use a magnetic thickness gauge to monitor coating quality

Technology Evolution Analysis

Based on GB 325, this standard mainly strengthens:

Improving the sealing level in view of the high volatility of CFC-11
Increasing the requirement for single-use in consideration of the environmental sensitivity of ozone depleting substances
Introducing polyvinyl chloride lining anti-corrosion technology
