3.Reserved Volume Tube: Safety Guarantee for Liquefied Gas sample 

To address the sample needs of volatile media such as liquefied gas, Hikelok has specially designed a reserved volume tube solution to comprehensively ensure sample safety:

Design Purpose: To provide sufficient vaporization space for cylinders containing liquefied gas, preventing a sharp pressure increase due to liquid expansion when the temperature rises, thereby effectively avoiding safety accidents.

Flexible Structural Design: The reserved volume tube can be welded either on the fitting or at the valve inlet end. The tube length can be customized according to actual needs to adapt to different specifications of cylinders and application scenarios.

4. Cleaning and Testing: Stringent Standards, Quality Assurance 

Hikelok implements strict cleaning and testing procedures for each sample cylinder, controlling product quality from the source to ensure user confidence:

Professional Cleaning Specifications: Executed in accordance with Hikelok cleaning specifications to remove impurities and contaminants from the production process, ensuring the internal cleanliness of the cylinder and preventing sample contamination.

Hydrostatic Testing: Each cylinder undergoes a hydrostatic test at 5/3 times the working pressure before leaving the factory. This rigorous pressure test verifies the product's safety and reliability, ensuring stable operation at the rated pressure.

5. Usage and Maintenance: Standardized Operation for Extended Service Life

Proper usage methods and regular maintenance are key to ensuring the long-term safe operation and extended service life of sample cylinders. The specific operation guidelines are as follows:

Usage Guidelines:

  • Liquefied Gas sample: Fill the cylinder from bottom to top, allowing residual gas inside the cylinder to be discharged from the top port (or reserved volume tube) to prevent excessive pressure caused by liquid expansion.
  • Gas sample: Fill the cylinder from top to bottom, allowing possible condensate in the pipeline to be discharged from the bottom port of the cylinder to ensure sample purity.

Maintenance Points:

Regular inspection and pressure testing of the cylinder are required, including:

  • External Surface: Check for obvious deformation or damage;
  • Internal Surface: Inspect for media corrosion;
  • Fittings and Valves Connected to the Cylinder: Verify normal working status and check for loose connections.

6. Qualifications and Certifications: International Standards, Global Recognition

Hikelok sample Cylinders comply with the requirements of the Transportable Pressure Equipment Directive (TPED), ensuring the compliance and safety of products worldwide. Add "-PD" at the end of the cylinder order model when placing an order to obtain TPED-certified products that meet international transportation and usage standards.

7. Choose Hikelok, Choose Safety and Precision
