Gas Sample Cylinder are specially designed pressure vessels used to collect, store, and transport gas samples safely—either at high pressure or normal pressure. They are widely used in petrochemical plants, natural gas fields, environmental monitoring, and laboratory analysis. A Gas Sampling Container is a sealed metal container that keeps gases uncontaminated, leak-free, and stable during transportation and testing.
Its main functions:
- The bottle is manufactured from seamless tubing, ensuring consistent wall thickness, dimensions,and capacity.
- Smooth inner neck taper facilitates easy cleaning and eliminates residual samples.
- Cold-formed NPT internal threads offer increased strength.
- One-piece extrusion avoids sample leakage associated with arc-welded constructions.
- Stainless steel-wrapped conductive Teflon-coated handles facilitate easy and durable handling of sampling bottles, preventing damage.
- Customized materials are more resistant to intergranular corrosion.
- Excellent sealing performance ensures a long lifespan.
- Customization is available according to customer requirements.
Typical Applications
- Oil & Gas Industry
- Natural gas composition testing (CH₄, C₂H₆, etc.)
- H₂S, CO₂, sulfur compounds analysis
- Refinery and petrochemical process gas sampling
- Industrial & Environmental Monitoring
- Exhaust gas sampling
- VOC sampling (volatile organic compounds)
- Pollution source monitoring
- Laboratory Analysis (GC / GC-MS)
- Gas sample preservation for chromatography analysis
Common Types of Gas Sample Cylinder
1) Standard Gas Sampling Cylinder (Double-Ended Needle Valves)
Most widely used
Needle valve on each end
Often rated for 3000 psi
2) Single-Ended Sampling Cylinder
Only one valve
Used for low-pressure applications
3) Sampling Cylinder with Dip Tube
Used for multi-phase samples (oil–gas–water).
4) Silonite / Passivated Coated Cylinders
Used for reactive gases such as sulfur compounds, ammonia, and VOCs.
