Tube cleaning is probably the most common application of water blasting, and the one that suffers the most from a lack of understanding of the dynamics involved. Inefficiencies in the tools used can easily reduce the cleaning power of the high pressure pump to as little as 10% or less of it's full capability. AWE personnel have resolved tube cleaning problems all over the region, often just by improving the efficiency of existing equipment. Many consumers have been amazed at what can be achieved with the application of the correct equipment and expertise. If you have a tube cleaning problem, Let us carry out a technical analysis. Its free, and we can resolve most problematic situations. RENT THE SOLUTION TO YOUR TUBE CLEANING PROBLEM Rigid Tube Lancing Systems for Cleaning Heat Exchanger Tubes Rigid Tube Lancing Systems are the best choice for reasons of safety and productivity. Compared to manual rodding, drilling, or circulating solvents or chemicals; rigid lancing systems are more effective. They also keep the operator farther away from the hazards of high pressure water, chemical splashback and exposure. Compared to flexible lancing systems, rigid lancing systems produce more force forward for unplugging, more torque for drilling, and keep the operator further away from the hazards of the job. That's why lancing systems have spread around the world over the last 15 years.
With the operator positioned 10 feet or more away from the tubesheet, at a pneumatic control panel, the lance moves into the tube with up to 400 lb of force. That allows the waterjet power to be applied forward, where it can go to work on plugged tubes. Because the lance stroke and rotation are air-driven at constant speeds, tube cleaning results are very uniform. The tube is more polished. So heat transfer is better, and longer-lasting than with manual methods.
Low labour costs are the most common reason to use old style manual lancing methods. But rigid lancing systems are reducing turnaround timing and making money for their owners. The reason is simple. Continuous process operations can lose as much as $15,000 in production revenue per hour of downtime. Smart maintenance service contractors are responding with technology, and bringing real value to their customers with rigid lancing systems. With such clear economic incentives, it makes no sense to accept the safety risks of manual methods. Lancing Systems are modular in design, making it easy and economical to convert lancing configuration, pressure level, and stroke length when needs change.
