GB 16164-1996 Small Dissolved Acetylene Cylinders
This General Standard, GB16164-1996, lays down the requirements and test methods for the design and manufacture of small dissolved acetylene cylinders. This regulation applies to the design and manufacture of small dissolved acetylene cylinders whose water capacity does not exceed 40L.
The requirements for small dissolved acetylene cylinders are as follows:
1. Structure: The small dissolved acetylene cylinders shall be equipped with a valve device in accordance with the design and a safety device. The plastic fusible plugs should be installed between the safety device and the internal pressure vessel to prevent overpressure inside the cylinder. The inlet of the valve device is to be equipped with a lid that can be opened during filling.
2. Design: The design of small dissolved acetylene cylinders shall conform to the relevant state regulations and standards, and shall not cause any leakage occurrence nor reduce the tank performance.
3. Markings: The small dissolved acetylene cylinders shall be marked with their water capacity and the corresponding unified color code number.
4. Wall thickness: The wall thickness of small dissolved acetylene cylinders shall conform to the corresponding requirements of the relevant state regulations and standards.
5. Quality of materials: The material and chemical composition of the small dissolved acetylene cylinders shall be in accordance with the relevant state regulations and standards.
6. Surface Treatment: The surface of the small dissolved acetylene cylinders must be free from stain and spot, moreover, no oil or grease is allowed.
7. Internal and external test: The internal and external pressure test of small dissolved acetylene cylinders must comply with the requirements of relevant state regulations and standards.
8. Packing: The small dissolved acetylene cylinders must be properly and securely packed during transportation to prevent any damages on the tanks.
Test methods for the small dissolved acetylene cylinders are as follows:
1. Appearance Test: The appearance of the small dissolved acetylene cylinders must be inspected first. During the inspection, any rusty or damaged tanks must be excluded from the process.
2. Thickness Test: The thickness of the small dissolved acetylene cylinders must be measured with ultrasonic wavelength method to ensure their safety and performance.
3. Leakage Test: The leakage test of the small dissolved acetylene cylinders must be conducted with a leak detector to determine the tightness of the tanks.
4. Pressure Test: The pressure test of the small dissolved acetylene cylinders must be conducted with a high-precision pressure gauge to determine their pressure range and safety level.
5. Material Test: The materials of the small dissolved acetylene cylinders must also be analyzed through sample testing to determine their safety and performance.
This General Standard applies to the design, manufacture, inspection and testing of small dissolved acetylene cylinders whose water capacity does not exceed 40L. As long as the requirements and test methods of this General Standard are followed, the small dissolved acetylene cylinders can be safely and effectively used.
