DESCRIPTION

AmsSystem sample cylinders are designed and manufactured in compliance with 49 CFR, the stringent regulation of U.S. Department of Transportation, to provide high reliability and long service life. Spun cylinders are made of seamless tubing to increase the wall thickness of neck transitions and thread areas which provides high strength to reduce the leak risks. The cylinders are internal sandblasted to ensure smooth surface and minimized remaining particles for easy cleaning. Application: Hydrocarbon sampling for refineries; Gas sampling for chromatography experiments; Condensate sampling for fossil fuel and nuclear power plants; As surge accumulators or reaction vessels; As snubbers in reactor feed lines.

Double-Ended, Single-Ended Sample Cylinders

* Working pressures up to 5000 psig (344 bar)

* Working Temperature: -17°C~93°C (0°F~200°F)

* Capacities from 40 to 3785 cm3 (1 gal)

* End connections 1/8″, 1/4″ and 1/2″ female NPT connections

* Cold-formed female NPT thread to provide high strength

* Spun cylinder body machined from seamless tubing to provide consistent wall thickness, size and capacity

* Full-penetration gas tungsten arc-weld construction to ensure no leak for sampling (single-ended cylinder only)

* DOT and non-DOT cylinders available

* Accessories, such as valves, relief devices, outage tubes, carrying handles, caps and plugs available

* PTFE Coating, Electropolishing, SilcoNert® 2000 (Sulfinert®) coated are available

Miniature Sample Cylinders

* Full-penetration butt weld constructions

* Each miniature cylinder is pressure tested at 1667 psig (115 bar) with Nitrogen

* SilcoNert® 2000 (Sulfinert®) coated sample cylinders available

Sampling Assemblies

* Working pressures up to 5000 psig (344 bar)

* Working Temperature: -17°C~93°C (0°F~200°F)

* Sampling assemblies are widely used in liquid, liquefied gas and gas collection and sampling as sampling accessories

* Simple structure for easy assembling and disassembling. Safe and reliable transportation with rupture disc

* Quick-connects at double ends with excellent sealing performance

* Customized upon request

 

 

Rupture Disc Kits

* Components: body, inlet ring, rupture disc and O-ring

* Protect sample cylinder from overpressurization by venting the gas to atmosphere

* Used to be installed in valves or rupture disc tees and sealed by O-rings

* Easily replaced without removing valves or tees from cylinders

 

Rupture Disc Tees

* With 2850 psig (196 bar) rapture disc and 1900 psig (130 bar) rapture disc

* End connections: inlet 1/4″ or 1/2″ male NPT, outlet 1/4″ female NPT

* These compact assemblies are designed for using with XINVAL valves

* Tees are made of 316 SS

* Each tee is supplied with a rupture disc kit

 

Nonrotating-stem Needle Valves with Rupture Disc Kits

* AmsSystem NV4 series needle valves up to 5000 psig (345 bar)

* With 2850 psig (196 bar) rapture disc and 1900 psig (130 bar) rapture disc

* End connections: inlet 1/4″ or 1/2″ male NPT, outlet 1/4″ female NPT

* Stainless steel 316L, 304L, Alloy 400 body materials

Spring Relief Devices

* Working Temperature: -29°C~121°C (-20°F~250°F)

* End connections: inlet 1/4″ or 3/8″ male NPT, outlet 1/4″ female NPT

* Spring relief devices are used with AmsSystem sample cylinders as a safety device

* Lubricant: Silicone-based

* Set pressure is in the middle of the set pressure range.

* When the system pressure reaches the set pressure, the device will open automatically to release the excess pressure in the system. After stabilizing the system pressure, the device will close automatically

Outage Tubes

* 1/4” and 1/2” NPT connections

* 316 SS and Alloy 400 available

* Outage tube is welded to the male thread end of an adapter. Screw the adapter with outage tube into the female thread end of a sample cylinder

* The outage tube provides a vapor space of desired volume in a cylinder with liquefied gas

* Used to keep a certain vapor space in a cylinder

* Customized outage tube length is available

Spare Parts and Accessories

Carrying Handle

The carrying handle provides convenience for transportation of sample cylinders. The handle is made of 304 SS and is available for 290 cm cylinders or larger cylinders.

 

Caps and Plugs

Caps and plugs are used for cylinder valves to protect the connections (tube fitting or NPT thread) from damages during cylinder transportation. For more details, please contact us AmsSystem.

 

End Caps

In order to enable users to transport pressurized samples in safety, end caps are offered by AmsSystem to protect valves from damages. Each end cap is screwed onto a neck ring that has been cold forged to the cylinder neck. End caps are made of carbon steel and are only available for 2250 cm and 3785 cm (1 gal) cylinders . AmsSystem angle pattern valves can be used for cylinders with end caps.
