Product Description

The heat treatment of liquefied petroleum gas cylinders is an indispensable phase in the manufacturing journey, dedicated to eradicating internal stress within the material. This process meticulously refines the metallographic structure while amplifying the mechanical prowess and pressure endurance of the cylinders. Stringent adherence to national standards, such as GB/T 5842 and ISO 22991, is paramount to guarantee the safety and longevity of these essential gas cylinders, ensuring they meet the highest benchmarks of service excellence.
1. Purpose of Heat Treatment
Eliminating residual stress is key: By applying high-temperature tempering or normalizing treatment, the internal stress generated during welding or cold working is thoroughly eliminated, safeguarding against stress corrosion cracks, thus fortifying the integrity of the LPG cylinders.
Refining the grain structure significantly boosts the steel's toughness and impact resilience, perfectly equipping it to handle cyclic loads under high-pressure conditions, ensuring reliability and durability.
Achieving stable size is crucial for minimizing deformation risks during future use, ensuring consistent performance and reliability over time.
2. Typical Process Parameters
Heating temperature typically ranges between 880-920ºC for normalizing, or 600-650ºC for tempering. These parameters are finely tuned based on the specific material, such as HP295 or HP345, to achieve optimal results.
Heat preservation time is calculated meticulously based on the cylinder's wall thickness, generally 1.5 to 3 minutes per millimeter, to guarantee uniform heat penetration throughout the material.
Cooling method involves air-cooling for normalizing, while post-tempering requires a gradual cooling to room temperature to prevent the onset of secondary stress, ensuring material integrity.
3. Quality Control Requirements
Hardness testing ensures the bottle body post-heat treatment has a hardness of ≤HB220, maintaining excellent processing performance and quality standards.
Mechanical property testing includes rigorous sampling tensile and impact tests, verifying that the tensile strength and elongation align with stringent standards, ensuring robust performance.
Non-destructive testing, via 100% magnetic particle or ultrasonic inspection, is conducted to meticulously eliminate any surface and internal defects, upholding product integrity.
4. Precautions
Regular calibration of heat treatment equipment to ensure furnace temperature uniformity (within ±10ºC) is vital for consistent output quality.
Strictly avoiding exceeding temperature limits or insufficient holding time is crucial to prevent material overburning or underperformance, preserving material properties.
Controlling environmental humidity is essential to avert oxidation and decarburization of steel during the high-temperature phase, ensuring material quality is maintained.
With the application of scientifically optimized heat treatment processes, LPG cylinders can confidently fulfill the 30-year design life requirement, guaranteeing safe and reliable gas storage and transportation.
5. Customized Services:
Tailored solutions are available to meet specific customer demands. Parameters and functions can be fine-tuned according to the actual equipment configuration, ensuring that the unique process requirements of each customer are met with precision.
