HOKE FORMED SAMPLING CYLINDERS

HOKE® Sampling Cylinders are designed and manufactured to stringent U.S. Department of Transportation (DOT) specifications as well as European Union Transportable Pressure Equipment Directive 2010/35/EU to provide long performance life and maximum safety to the user.

These cylinders are fabricated from seamless tubing or pipe with increased wall thickness in the threaded area, which prevents expansion when valves are installed. Completely formed ends maximise strength and eliminate potential leak paths. Internal sandblasting removes surface imperfections and removes foreign particles.

Single- and double-ended cylinders are available as standard in a variety of capacities from 10 milliliters to 3.5 gallons.

Design Features:

• Capacity ranges from 10 mL through 3.5 gallons
• Cylinder ends come in 1/8", ¼ ", 3/8" and ½ " NPT female connections (depends on capacity)
• Standard cylinders are formed from seamless drawn 316 SS or MONEL® and Hastelloy®
• Precision spinning operation eliminates internal pockets and provides easy flow of the sample
• All models are internally sandblasted to remove surface imperfections and eliminate foreign particles
• Single- and double-ended cylinders in most capacities are available as standard
• Rugged wall thickness – extra strength around threads
• Cylinders may be ordered with valves, relief devices, dip tubes, carrying handles, collar and flanges and end caps
• The interior of HOKE® cylinders are available with a special FEP lining which provides excellent lubricity and very low permeability. To order, add “TL” following the cylinder part number. Restek®, Silcosteel®, and Sulfinert® surface treatments available for many sizes. Consult factory.
• Special High Tolerance NPT Thread
