Tungsten cylinder：

Wanan Sample Cylinder is widely used on petroleum device, chemical device and so on, especially leak-proof sampling for toxic, harmful, flammable, explosive and some other dangerous gas or liquid with medium or low pressure, like residual oil hydrotreating unit, heavy oil catalytic cracking unit, gas fractionation unit and so on. Sample collected by Wanan sample cylinder is authentic, accurate, no residual liquid, no residual gas emissions, protecting operators from harmful media, meanwhile no harm to environment, and eliminating accident from flammable, explosive median during sampling.

Features:

♥ Smooth internal neck transition allows easy cleaning and eliminates trapped fluids.
♥ Cold-formed female NPT threads provide greater strength.
♥ Heavy-wall end connections provide strength and resist flaring.
♥ Full-penetration gas tungsten arc-weld construction provides leak-tight sample containment.
♥ Sizes from 40 to 3785 cm3 (1 gal)
♥ Working pressures up to 5000 psig (344 bar) 
♥ 304, 316L stainless steel resists intergranular corrosion.
♥ 304L and 316L stainless steel double-ended cylinders are available with dual certification to DOT and TC requirements.
