Automated LPG Cylinder Heat Treatment Production Line Solutions

Product Description

The paramount process of heat treating liquefied petroleum gas cylinders is indispensable in manufacturing, serving the vital role of eradicating internal material stress, refining metallographic structure, and significantly boosting both the mechanical properties and pressure resistance strength of the cylinders. Adherence to national standards like GB/T 5842, ISO 22991, etc., is crucial to ensure the safety and longevity of these gas cylinders, reflecting unmatched commitment to quality.
1. Purpose of Heat Treatment
Eliminating Residual Stress: By utilizing meticulous high-temperature tempering or normalizing treatments, this process effectively eradicates internal stress caused by welding or cold working, thereby safeguarding against stress corrosion cracks.
Refining Grain Structure: Elevate the toughness and impact resistance of steel, enabling endurance under cyclic loads in demanding high-pressure environments.
Stable Size: Ensure dimensional stability to mitigate the risk of deformation during the subsequent use phase.
2. Typical Process Parameters
Heating Temperature: Typically set at 880-920ºC for normalizing or 600-650ºC for tempering, with specific adjustments made according to material types such as HP295, HP345, ensuring optimal results.
Heat Preservation Time: Precisely calculated based on cylinder wall thickness (generally 1.5 to 3 minutes per mm) to guarantee consistent heat penetration.
Cooling Method: Normalizing involves air-cooling, whereas post-tempering requires a slow return to room temperature to avert the emergence of secondary stress.
3. Quality Control Requirements
Hardness Testing: Ensuring post-treatment body hardness does not exceed HB220, maintaining superior processing performance.
Mechanical Property Testing: Conduct thorough sampling tensile and impact tests to confirm compliance with tensile strength and elongation standards.
Non-Destructive Testing: Employ 100% magnetic particle or ultrasonic inspections to detect and eradicate surface and internal defects.
4. Precautions
Regular Calibration: Heat treatment equipment must undergo regular furnace temperature uniformity calibration tests (within ±10ºC) to maintain precision.
Temperature Management: Strictly avoid exceeding temperature thresholds or insufficient holding times to prevent material overburning or underperformance.
Environmental Control: Maintain optimal environmental humidity to avert oxidation and decarburization during critical high-temperature phases.
By leveraging scientific heat treatment processes, LPG cylinders achieve the design life expectancy of 30 years, guaranteeing unparalleled safety and reliability in gas storage and transportation.
5. Customized Services:
Tailor-Made Solutions: We offer bespoke solutions aligned with customer requirements. Specific parameters and functionalities can be finely tuned according to the actual equipment configuration, meeting diverse process needs.
