A critical aspect in petrochemical industry is plant maintenance to correct fluid flow problems. Plant maintenance and efficiency depends on correcting cavitation, which decreases flow capability, leads to pipe damage, increased noise emission, valve/pipe component erosion and mechanical vibration. Adding a CRV® to correct fluid flow problems is proactive, corrective and preventive maintenance.

Problem - Pump Cavitation: Pumping systems experience cavitation, cavities or bubbles form in the liquid that is being pumped due to low pressure from the suction side of the pump.    

Problem - Pump & Check Valve Vibration: Check valves, respond to flow and pressure disturbances. Such turbulence cause the pin to fail, leakage though the pin starts, and the valve seat will not seal. CRV® installation reduced the noise, extended seal, bearing, impeller life, increased delivered head and flow.

Problem - Elbow Erosion: Elbow erosion is eliminated by preventing turbulence, internal pressure gradients, and cavitation, through the use of an internally hardened CRV®.                                              

Case 1: Replaced elbow every 3 weeks: cost $150,000.

Savings since installation of CRV®: Over $3 million annually.

Case 2: Refinery blow down - spent catalyst replaced elbow 3 times a year: cost $300,000/day of lost production.

Savings since installation over $4 million annually.
