Specification for safe use of non refillable welded steel cylinders for industrial use

The safe use of non refillable welded steel cylinders for industrial use must comply with strict regulations, and the following are key points:

Check before use

Appearance inspection: Check the surface of the steel cylinder for defects such as corrosion, dents, cracks, etc. The cylinder body should be free of wrinkles, and accessories such as the valve and cap should be intact and undamaged.

Identification verification: Confirm that the manufacturing mark, filling medium, test pressure, large filling amount, and other markings on the steel cylinder are clear and complete, consistent with actual usage requirements, and clearly marked with the words "non repeated filling".

Pressure check: Before use, check whether the pressure inside the bottle is normal, ensure that the pressure is within the specified range, and avoid overpressure or underpressure use.

Environmental requirements for use

Temperature limit: The usage environment temperature should be between -40 ℃ and 60 ℃, avoiding prolonged storage or use in high, low, or direct sunlight environments.

Stay away from heat and fire sources: Steel cylinders should be kept away from open flames, heat sources, electrical equipment, etc. The distance from the fire source should not be less than 10 meters to prevent danger caused by a sharp increase in pressure inside the cylinder due to temperature rise.

Good ventilation: The place of use should maintain good ventilation and avoid use in enclosed spaces to prevent gas leakage and accumulation, which can form explosive mixtures.

Operating Specifications

Proper placement: Steel cylinders should be placed upright and anti tipping measures should be taken, such as using fixed brackets or straps to secure them. It is strictly prohibited to place it horizontally or upside down to prevent leakage of the medium inside the bottle or other safety issues.

Slow switching valve: When opening or closing the bottle valve, special tools should be used to move slowly and avoid excessive force that may damage the bottle valve or generate static sparks.

Special tool usage: The pipes, valves, pressure reducers, and other equipment used to connect the steel cylinder should match the interface of the cylinder and ensure that the connection is firm and well sealed. Do not use mismatched or damaged tools and equipment.

Prohibition of unauthorized modification: It is strictly prohibited to carry out unauthorized modification, welding, cutting and other operations on steel cylinders to avoid damaging the structural integrity of the cylinders and causing safety accidents.

Filling and usage restrictions

Strictly prohibit repeated filling: Non refilled welded steel cylinders can only be filled once and should be scrapped according to regulations after use. They cannot be refilled and used again.

Control the filling amount: The filling unit should strictly fill according to the rated filling amount of the steel cylinder, and should not overfill to ensure that the pressure and capacity of the medium inside the cylinder are within a safe range.

Specialized cylinder: Steel cylinders should be used according to the prescribed filling medium, and should not be mixed or mistakenly filled with other gases to avoid danger caused by gas reactions.

emergency response

Leakage handling: If a cylinder leak is found, the cylinder valve should be immediately closed, the cylinder should be moved to a well ventilated and safe area away from sources of fire, and professional personnel should be notified in a timely manner for handling. It is strictly prohibited to use open flames, electrical equipment, etc. at the leakage site to prevent explosions or fires.

Fire response: In the event of a fire, immediately dial the fire alarm number and take appropriate firefighting measures. Select appropriate fire extinguishing agents based on the properties of the medium inside the steel cylinder, such as carbon dioxide, dry powder, etc. It is strictly prohibited to use water to extinguish fires caused by certain flammable and explosive gases.

Personnel protection: When handling safety accidents, operators should wear necessary protective equipment such as goggles, gloves, masks, etc. to avoid contact with leaked gases or injury.

The safe use of non refillable welded steel cylinders for industrial use is crucial. The user and operator should strictly comply with relevant safety regulations, conduct regular safety inspections and maintenance, and ensure the safe operation of the steel cylinders. If any safety hazards or abnormal situations are found in the steel cylinder, it should be stopped from use in a timely manner and professional organizations should be contacted for handling.
