Sampling Cylinders permit the extraction of a sample from a remote process location and provide safe containment for storage and transportation to the laboratory for analysis. These cylinders are rated to 1800 psi at room temperature for liquids and gases. Some applications include hydrocarbon sampling in refineries, gas sampling in chromatography and condensate sampling in fossil-fuel In similar applications, petrochemical facilities and gas processing plants utilize sample cylinders. Pressure surge accumulators or reaction vessels are other common uses for sample cylinders.

Transportation Specifications: DOT-3E1800 per 49CFR 178.42

Material Traceability

Raw material is heat code traceable. This traceability follows each cylinder through manufacture, heat treating, cleaning and pressure testing.

Cylinder Manufacturing Standards

DOT CFFC, FRP-1, FRP-2, 3A, 3AA, 3AL, 3E, 3HT, 39, NGV2, FMVSS, HSE FW1/FW2, TUV, KHK, MIL-C-7905, MS26545, MIL-R-8573, EN1975, 12245 and others.

Approval of T.P.E.D. { Transportation Pressure Equipment Directive} is imminent.
