SamplingCylindersFTI’s range of high pressure gas sampling cylinders is the ideal solution for a wide array of sample collection and analysis needs. The range is designed for and used across the world in various industries, including petrochemical refineries and well sites, analytic laboratories, alternative fuel technologies, and manufacturing.

Benefits of the FTI range of sampling cylinders:

  • Seamless 316 stainless steel construction. All FTI’s sampling cylinders are made from seamless 316SS tubing, providing consistencies in wall thickness and internal volume, as well as improved integrity and corrosion resistance over standard 304SS offerings.
  • Hot spun dome and neck profiles. All FTI’s sampling cylinders are formed by a CNC-controlled hot spinning process that provides a smooth, contoured sidewall-to-neck transition that eliminates the possibility of crevices or pockets that can trap sample residuals. Further, the smooth interior surface of FTI cylinders make for easier, more effective cleanings between samples.
  • Dual female NPT threads. Tightly controlled female NPT threads are machined into both ends of the cylinders using high precision, computer-controlled milling machines. FTI sampling cylinders are available with various thread measurements in line with available industry standard valves and fittings.
  • Built to global regulatory standards. FTI sampling cylinders are designed, manufactured, tested, and inspected to the major global regulatory standards, such as U.S. Department of Transportation (DOT) and the Transportable Pressure Equipment Directive (TPED) – range available upon request.

H-285Ham-Let H-285 Needle Valve With Rupture Disc

The H-285 forged valve body, union bonnet and knob handle with rupture disc, is designed to be mounted on our sample cylinders.

The Rupture disc provides protection against over pressure in sampling units by venting the media to the atmosphere on a certain nominal rupture values (1900 and 2850 PSI). The rupture disc element is welded to a carrier that is assembled to the valve with an O-ring seal. A rupture disc unit can be easily replaced in the field while the valve remains connected to the sampling unit.
