※Extremely low inspection costs

※Equipped with a high dynamic range flat-panel detector (FPD)

※Inspection efficiency: ~3 seconds per frame

※Image quality meets the latest GB/T17925-2009 and NB/T47013.11-2015 standards

Universal material testing machine

※Mechanical Properties Testing: Used to examine the tensile, compressive, and flexural properties of steel cylinder materials to ensure they meet design and safety standards.
※Material Quality Control: By testing parameters such as strength, elongation, and yield point, the quality and consistency of steel cylinder materials are assessed to ensure that the raw materials used in the production process meet requirements.
※Welding Quality Inspection: Strength tests are performed on steel cylinder welds to assess weld quality and ensure the strength and safety of welds.
※Destructive Testing: Destructive testing is performed under specified loads to verify the pressure-bearing capacity and maximum load before rupture of steel cylinders, ensuring their safety in actual use.
※Data Recording and Analysis: Test data is recorded and analyzed to provide a reference for quality control and production process improvements.

Through these functions, universal testing equipment plays a key role in quality control and safety assurance in steel cylinder production lines, ensuring that produced cylinders meet relevant standards and requirements.

Materials chemistry element analysis equipment for LPG cylinders

※Composition Testing: Analyzes the chemical composition of raw materials and welding materials used in steel cylinders to ensure they meet specific chemical composition standards and requirements.
※Quality Control: Accurately analyzes the chemical composition of materials to verify their purity and consistency, preventing the use of substandard materials and thus ensuring the overall quality of the cylinders.
※Material Identification: Confirms the type and brand of materials used in steel cylinders to ensure they meet design specifications and standards.
※Production Process Monitoring: Regularly tests the chemical composition of materials during the production process to promptly identify and correct any deviations, ensuring the stability and consistency of the production process.
※Safety Assurance: Strictly control the chemical composition of materials to prevent safety incidents such as cylinder explosions or leaks caused by substandard materials.

Through these functions, chemical element analyzers ensure the accuracy of material composition during the production process, thereby guaranteeing the quality and safety of finished cylinders.

Burst testing equipment for LPG cylinders

※Safety Performance Verification: By applying high pressure to cylinders until they burst, we verify their extreme pressure-bearing capacity and ensure they will not burst under normal operating conditions.
※Quality Control: We inspect cylinders for defects in manufacturing, such as material and welding defects, to ensure each cylinder meets quality standards.
※Design Verification: We verify the rationality of the cylinder design and evaluate its performance within the maximum pressure range, providing a basis for design improvements.
※Regulatory Compliance: We ensure that cylinders comply with relevant national and industry standards, using burst testing to meet regulatory and certification requirements.
※Safety Assurance: By performing destructive tests simulating extreme conditions, we ensure that cylinders have sufficient safety margins in actual use, reducing the risk of accidents.

Through these functions, burst testing plays a critical role in quality and safety assurance in cylinder production lines, ensuring the reliability and safety of cylinders under various operating conditions. It also provides a direct indicator of weld quality.
