Polystyrene is an aromatic polymer made from the aromatic monomer styrene, a liquid hydrocarbon that is commercially manufactured from petroleum by the chemical industry. Polystyrene is a thermoplastic substance, normally existing in solid state at room temperature, but melting if heated (for molding or extrusion), and becoming solid again when cooling off. Pure solid polystyrene is a colorless, hard plastic with limited flexibility. It can be cast into molds with fine detail. Polystyrene can be transparent or can be made to take on various colors.

ABS is derived from acrylonitrile, butadiene, and styrene. Acrylonitrile is a synthetic monomer produced from propylene and ammonia; butadiene is a petroleum hydrocarbon obtained from butane; and styrene monomers, derived from coal, are commercially obtained from benzene and ethylene from coal. The advantage of ABS is that this material combines the strength and rigidity of the acrylonitrile and styrene polymers with the toughness of the polybutadiene rubber. The most important mechanical properties of ABS are resistance and toughness.

Strahman sampling valves extract fluid directly from the pipeline. They can be used under high pressure or even high vacuum conditions. The ram tip is contoured to match the pipe’s inside surface when closed so as not to disrupt fluid flow in the pipe.There is no flange between the main pipe and valve body. This feature is effective for polymer applications to prevent polymer freezing in the valve.Strahman’s line of sampling valves produces samples without failure. (Sediment or clogging cannot stop this valve from producing a live sample.) In the closed position, the valve piston extends to the inner surface of the pipe and prevents any possibility of the valve inlet becoming plugged. When the valve is in the open position, the piston retracts into the bonnet allowing a full flow.
