Optimize Nozzle Placement and Improve Tank Cleaning Efficiency With Tank Cleaning Lances

BETE tank cleaning lances provide a custom-engineered solution for optimal nozzle placement inside a tank. We design and fabricate all lances at our facility to ensure close coordination through every manufacturing phase.

We are capable of symmetrical and asymmetrical designs and can add a retractable feature for Clean-In-Place (CIP) or Clean-Out-of-Place (COP) applications. We can fabricate a customized lance for any BETE tank cleaning nozzle. BETE welders can provide assemblies manufactured to ASME B31.3 Code for Process Piping and other applicable ASME Codes/Standards in various materials.

Retractable Tank Cleaning Lances

Retractable lances allow you to withdraw your nozzle and isolate it from the process so that it does not come in contact with the product. Nozzle maintenance is easy with retractable lance because it can be entirely removed for servicing without taking your process offline. Once you have serviced, cleaned, or inspected the nozzle – reattach it to the lance.

Considerations For Using Tank Cleaning Lances

Several factors explain why a tank cleaning lance may improve your cleaning process. Our engineers can evaluate your new or existing process to recommend solutions for achieving optimal cleaning performance and reliability. Discover why you would use a tank cleaning lance using the slide arrows below.

Tank cleaning nozzles should be positioned in the upper part of the tank when possible. Nozzles placed too close to the ceiling of the tank will cause the sprays to deflect off the curved tank ceiling, resulting in poor cleaning impact. Tank cleaning lances are an ideal solution for optimal placement.

A guideline for nozzle placement is 1/3 the overall height of the tank.

(H3) Nozzle = 1/3 Overall Tank Height (H)
Agitator blades inside a tank.

Agitators, baffles, and pipes prevent spray from reaching the areas behind them, known as spray shadowing.

In such cases, more than one nozzle should be installed inside the tank. The nozzles can be positioned correctly with a lance for the sprays to overlap and ensure complete cleaning coverage.

Retractable tank cleaning lances are the perfect solution when a nozzle cannot remain in the process. Prevent contamination and bacteria build-up by removing the nozzle with the retractable mechanism.

Installation and maintenance are easy with a retractable tank cleaning lance.

Case Studies


FlexFlow® Spray System Improves Cookie Production Efficiency With Precision Lubrication on Bakery Equipment

During cookie production, many bakeries use an automated cutting knife to portion dough onto a conveyor. Without proper lubrication, the cutting knife and conveyor belt become sticky with built-up dough, forcing workers to stop the process so they can clean the equipment manually. This leads to excess labor hours and lost productivity.

Automated Spray System for Chemical Processing Enhances Gas Cooling Performance and Reliability

A demineralized water injection system is needed to quench calciner furnace exhaust gas upstream of dust collection equipment at a chemical processing plant during the manufacture of specialty catalyst. Spray nozzles need to produce small droplet sizes to achieve complete evaporation, which requires pumps for high-pressure water supply, controls, and instrumentation to regulate and monitor the gas temperature.

Avoiding Costly Damage and Repair of Refinery Equipment With Spray Injectors

Quills are not always the best method for injecting chemical inhibitors where spray distribution is critical. For these applications, fabricated spray injectors with a nozzle produce more accurate results for spray injection.
