NAI LOK Stainless Steel 904L SS316 3000psi Double-Ended 1/4 Female NPT Sample Cylinders for Sampling System 1000m
Oil Laboratory Sampling System Stainless Steel 316 5000 Psi 300ml 500ml Gas Sample Cylinder CNG Double Ended 1/4" Fnpt Cylinders
NAI-LOK Sample Cylinder - Double Ended, 1/2" & 1/4" Female NPT - Special Alloy & Duplex Steel Construction
The NAI-LOK Double-Ended Sample Cylinder is a high-performance sampling device designed for demanding industrial applications. Featuring 1/2" and 1/4" female NPT connections, this cylinder ensures secure and leak-proof fluid sampling in high-pressure and corrosive environments. Constructed from special alloys and duplex steel, it delivers exceptional resistance to corrosion, erosion, and extreme temperatures, making it ideal for oil & gas, chemical processing, petrochemical, and power generation industries.
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.
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.
