Product Description

Product Description

Premium Double-Ended LPG LNG Seamless Sample Cylinders for High-Pressure Applications

Engineered for rigorous gas and fluid sampling in oil & gas, petrochemical, and offshore environments, our double-ended sample cylinders combine robust construction with unmatched reliability. Available in capacities from 150mL to 1-gallon (3785mL), these cylinders are built to withstand extreme pressures and corrosive conditions.

Key Features:

• Military-Grade Pressure Ratings: Certified for 1800psi, 3000psi, or 5000 PSIG (344 bar) working pressure, ideal for HPHT (High-Pressure High-Temperature) applications.

• Zero-Leak Seamless Design: Manufactured from cold-drawn tubing for uniform wall thickness, eliminating weld failure risks and ensuring maximum safety.

• Superior Corrosion Resistance: Standard 316L stainless steel, with optional high-performance materials including 904L (chloride-resistant), Alloy 625 (Inconel®), Hastelloy®, Monel®, or super duplex steel (UNS S31803/S32750/S32760) for extreme environments.

• Certification: DOT Certified for safe and compliant operation.
  NACE MR0175 Compliance: Certified for sour service (H2S-rich) and chloride stress corrosion cracking (SCC) resistance, making them ideal for offshore and acidic conditions.

• Double-Ended Configuration: Features 1/4" or 1/2" FNPT, Female BSPP, or BSPT ports with needle valve plug protection for secure transport and seamless integration into manifold sampling systems.

• Leak-Free Performance: Equipped with pre-installed needle valves and NPT threads for bubble-tight sealing and quick-connect functionality.

• Specialized Coatings: Optional vulcanization, sulfur passivation, or PTFE coating for enhanced H2S and sulfur resistance (API compliant).

• Precision-Machined Interior: Smooth internal finish minimizes contamination, ensuring accurate and representative samples.

• Customizable Solutions: Available in 150mL, 300mL, 500mL, 1000mL, 1500mL, 2000mL, and 1-gallon (3785mL) sizes, with automated sampling integration upon request.

• Designed for durability and precision, these cylinders deliver reliable performance in the harshest conditions-ensuring safety, efficiency, and accuracy in every sample.

Product Parameters

 

Stainless Steel 316	Excellent general corrosion resistance, good mechanical strength, and weldability. SS316L (low carbon) offers superior resistance to sensitization (carbide precipitation) in welded applications.
6 Moly (6% Molybdenum Super Austenitic, UNS S31254, N08367)	Enhanced pitting/crevice corrosion resistance (PREN >40), high chloride tolerance, and acid resistance surpassing standard stainless steels.
Duplex Steel                                              (UNS S31803 / S32205)	Excellent chloride and stress corrosion cracking resistance.
Super Duplex Steel                                     (UNS S32750 / S32760)	Enhanced strength and pitting resistance for harsh offshore/chemical environments.
Inconel ® 625 (UNS N06625)	Resists oxidation and acidic corrosion.
Hastelloy ® C276                                        (UNS N10276)	Ideal for sulfuric, hydrochloric, and other aggressive acids.
Monel ® 400 (UNS N04400)	Superior performance in seawater and hydraulic flow acid.

Application

 

• Oil & Gas: Wellhead sampling, produced fluids, sour gas (H2S/CO2).(HPHT, sour gas, offshore)

• Chemical Processing: Acid, alkali, and solvent sampling.
  Refinery & Petrochemical Process Monitoring 

• Environmental & Emissions Testing

• Geothermal & Industrial Gas Analysis

• Power Plants: Boiler water, steam, and condensate analysis.

• Pharmaceutical & Food: High-purity fluid transfer.

• Offshore/Marine: Seawater sampling, splash zones, and high-salinity brines.

• Chemical/Petrochemical: Concentrated chlorides, sulfuric/phosphoric acids, and bleach (hypochlorite) solutions.

• Pollution Control: Flue gas desulfurization (FGD) scrubber systems.

• Pulp & Paper: Aggressive bleaching liquors and acidic digesters.

• Alternative to Duplex: When higher ductility or avoidance of sigma phase (from heat exposure) is required.
