Introduction
1. Scope of the standard
GB/T 34531—2017 is applicable to liquefied dimethyl ether cylinders with a design pressure of 1.6 MPa and a nominal volume not exceeding 150 L.
2. Comparison table of inspection items
| Items | Content requirements | Technical specifications |
|---|---|---|
| Appearance inspection | Inspection for defects such as cracks, bulges, corrosion, etc. | Remaining wall thickness shall not be less than designed wall thickness |
| Wall thickness measurement | Fixed-point thickness measurement and local thickness measurement | Assessment of minimum remaining wall thickness |
| Hydraulic pressure test | Pressure 2.4 MPa, hold pressure for 1 minute | No leakage, visible deformation |
3. Implementation background and technological evolution
With the widespread use of liquefied dimethyl ether, the safety of cylinders has become increasingly prominent. This standard is based on years of practical experience to ensure safe use under extreme temperature conditions.
4. Implementation suggestions
- Regularly train inspection personnel to ensure familiarity with various technical requirements
- Use advanced testing equipment, such as ultrasonic thickness gauges and non-destructive testing instruments
- Establish a cylinder inspection database for traceability management
