Introduction

Core changes in the standard revision

Technical field	2022 edition	2023 edition
Model representation	Roman letter modification number	Chinese character modification number (example: YSP23.9/壹/10)
Structural type	Gas-liquid two-phase bottle	Single liquid phase bottle (YSP118/液/49.5 needs to be marked with "液")
Safety management	No clear restrictions on where to use	YSP118 series is prohibited from being installed indoors in buildings, and other models are prohibited from entering crowded places.

Key design parameters

Working conditions:Ambient temperature -40℃~60℃, nominal working pressure 2.1MPa
Volume range:Nominal volume ≤150L (new YSP118/49.5 large capacity model)
Material requirements:

Chemical composition: C≤0.20%, Mn content 0.7-1.50%
Mechanical properties: Yield ratio ≤0.85 when tensile strength ≥490MPa

Key points of manufacturing process control

Welding specifications

Weld type	Technical requirements
Butt weld	Reinforcement height 0-2.5mm, misalignment ≤0.1S₀
Electronic tag welding	Laser welding, must pass 144h salt spray test

Heat treatment requirements

Overall heat treatment temperature deviation ±25℃, temperature curve must be automatically recorded, and re-heat treatment must be performed after repair

Inspection and testing system

Batch inspection rules:

Radiographic inspection: 20% random inspection of longitudinal circumferential welds
Burst test: volume deformation rate ≥12% (R_m>490MPa)
Pressure cycle: 12,000 times 3.2MPa pressure test

Electronic identification verification: Need to pass 800-1000℃ flame combustion test for 1 minute

Implementation suggestions

Manufacturers

1. Establish electronic tag welding process assessment files
2. The water pressure test data retention period is extended to 8 years
3. Note that the diameter of the YSP118 series shield is increased to 380mm

User

1. Regularly check that the steel stamp depth is ≥0.7mm
2. The liquid phase bottle needs to be connected to a special gasification device
3. It is strictly forbidden to modify the electronic traceability mark without authorization
