Product Description

The process of heat treating liquefied petroleum gas cylinders is an essential phase in their production. It serves to alleviate internal stress within the materials, optimize the metallographic architecture, and significantly enhance both the mechanical properties and the pressure resistance strength of the cylinders. Upholding stringent adherence to esteemed national standards, such as GB/T 5842 and ISO 22991, is imperative. This meticulous adherence guarantees both the safety and the longevity of the gas cylinders, fostering trust and reliability in each product.
1. Purpose of Heat Treatment:
Eliminating Residual Stress: Utilizing high-temperature tempering or normalizing procedures, we actively remove internal stress that arises during welding or cold working. This preventive measure is crucial to avert the formation of stress corrosion cracks, thereby enhancing the durability and integrity of the cylinders.
Refine the Grain Structure: This process is pivotal in augmenting the steel's toughness and impact resistance. It enables the material to effectively withstand cyclic loads, particularly under high-pressure conditions.
Stable Size: The procedure significantly minimizes the risk of deformation during the cylinder's subsequent use, ensuring consistent performance.
2. Typical Process Parameters:
Heating Temperature: This process typically involves a temperature range of 880-920ºC for normalizing, or 600-650ºC for tempering. These specific temperatures are meticulously adjusted based on the material composition, such as HP295 or HP345, to achieve optimal results.
Heat Preservation Time: Carefully calculated based on the wall thickness of the cylinder, typically ranging from 1.5 to 3 minutes per millimeter, ensuring uniform heat penetration throughout the material.
Cooling Method: Normalizing employs air cooling, whereas post-tempering requires a gradual cool down to room temperature to prevent secondary stress, reinforcing material stability.
3. Quality Control Requirements:
Hardness Testing: Post heat treatment, the cylinder's hardness must not exceed HB220, ensuring optimal processing performance and reliability.
Mechanical Property Testing: Comprehensive tensile and impact tests are systematically conducted to confirm that the tensile strength and elongation adhere to stringent standards.
Non-Destructive Testing: A 100% thorough inspection via magnetic particle or ultrasonic methods is mandatory. This ensures the complete elimination of any surface or internal defects, guaranteeing product integrity.
4. Precautions:
Regular Calibration: The uniformity of the furnace temperature must be calibrated regularly, maintaining accuracy within ±10ºC to ensure consistent heat treatment quality.
Strict Temperature Control: It is imperative to avoid exceeding temperature limits or reducing hold time to prevent material overburning or performance deficiencies.
Environmental Control: Maintaining the humidity of the environment is vital to prevent oxidation and decarburization of steel during high-temperature phases, ensuring the material's integrity.
The deployment of a scientifically robust heat treatment process enables LPG cylinders to meet a 30-year design life requirement, assuring the safety and reliability of gas storage and transportation.
