The Vortab Company Vortab Flow Conditioners

The efficiency and service life of pumps can be extended by following the manufacturer’s installation recommendation for pipe straight run entering the pump. When cramped pump houses or restricted pipe runs make this impractical and costly, Vortab Flow Conditioners from The Vortab Company can help to overcome this challenge by delivering a uniform, swirl-free flow profile to the pump inlet in as little as six pipe diameters.

Upstream flow disturbers, such as elbows, expanders or reducers, and valves, often produce non-uniform, non-repeatable and swirling fluid flow entering the pump that can lead to pump cavitation and other issues causing premature wear. The result is extra maintenance, expensive repairs and/or premature replacement, which can take equipment offline. Vortab products can provide effective process conditioning to protect pumps.

Vortab Company’s product line of process flow conditioners, with its exclusive flow profile and anti-swirl tab design, correct flow disturbances to mimic adequate pipe straight run and produce a highly repeatable, symmetrical flow profile. The pressure drop flow conditioning technology can reduce energy costs and minimise process design considerations. Their use can also eliminate the extra pipe cost and technician labour for additional lengths of pipe straight run and/or moving equipment around to accommodate new pumps.

Swirl reduction and velocity profile correction occur naturally in long lengths of straight pipe due to diffusion, friction and turbulent mixing. The flow conditioner’s anti-swirl and inclined vortex generating profile correction tabs, projecting from the inside pipe surface, generate vortices that accelerate these natural pipe effects to create a uniform, non-swirling, symmetrical flow profile in a much shorter section of pipe.

The simple, flexible designs of the Vortab Elbow (Model VEL) and the Vortab Insertion Sleeve (Model VIS) configurations can provide a cost-effective, easy-to-install solution that supports proper pump installation. They can be made from carbon steel, 316L stainless steel or Hastelloy C-276 and in almost any pipe size. A variety of process connections is also available — ANSI flanges, male NPT threads, butt welded preps or retaining wafers.

The Vortab range of flow conditioners is available from AMS Instrumentation & Calibration in a range of sizes and connections.
