BOILER DESCALING CHEMICALS
Cleanix B77 – The Ultimate Solution for Industrial Scale Removal
General Information
Boilers, chiller condensers, heat exchangers, and pipelines play critical roles in industrial operations, and maintaining their efficiency is essential. Over time, these systems are prone to scale build-up, reducing their efficiency and posing risks of corrosion. Cleanix B77, developed by Chemmax, has emerged as a trusted solution for descaling a wide range of industrial equipment.
Cleanix B77, often referred to simply as B77, was created based on extensive customer feedback, focusing on delivering a product that is effective, fast, thorough, and safe. The result is a high-performance liquid compound that targets and eliminates various types of inorganic scales, such as Silica, Calcium, Magnesium, and rust-based deposits, all while protecting the parent metal from corrosion during the descaling process.
Engineered with a high concentration of active ingredients, B77 not only excels in its performance but also optimizes packaging and shipping costs for industrial users.
Key Benefits and Advantages of B77
1. Exceptional Scale Removal Power
B77 is formulated with a potent combination of inorganic scale removers designed to break down even the toughest deposits. Whether dealing with Silica, Calcium, Magnesium, rust, or mud, B77 attacks these deposits comprehensively, ensuring the scale is dislodged uniformly without causing fragmentation or blockage.
2. Rapid Action
One of the standout features of B77 is its quick response time. The chemical effectively dissolves multiple types of scale simultaneously, significantly reducing soaking time to just 3 to 12 hours, depending on the scales thickness and type. This rapid action helps minimize downtime during maintenance.
3. Simplified Descaling Process
Unlike traditional descaling agents, B77 eliminates the need for several time-consuming steps:
■ No alkaline cleaning is required for removing Silica-based scales.
■ No additional passivation of iron and steel is necessary, which typically takes 12 to 48 hours, as B77 provides passivation during the soaking process.
4. Thorough and Customized Descaling
B77’s multi-component system allows for customization tailored to each customer’s specific needs and equipment. This ensures that all types of scale and rust are thoroughly removed, leaving no residual deposits that could cause corrosion or pipe perforation.
5. Safe for Stainless Steel Surfaces
B77 is free from chloride compounds, making it safe and highly effective for descaling stainless steel surfaces like coils and plate heat exchangers, where other chemicals may cause damage.
6. Prevents Large Scale Flakes
When dealing with thick scale deposits, traditional descaling agents often cause large flakes that can block small-diameter pipes. B77 works by softening and gradually dislodging the scale, preventing blockages and reducing the risk of local overheating or pipe explosions post-cleaning.
7. Corrosion Protection
B77 is equipped with a built-in corrosion inhibitor, ively protecting the parent metal while aggressively removing the scale. This dual action allows for a safe descaling process without compromising the integrity of the equipment.
8. Easy and Efficient Application
B77 is a ready-to-use liquid that does not require dilution before use, making it easy to apply. Its high concentration means smaller volumes are required, reducing overall chemical usage and storage needs.
9. Cold Pickling Capability
B77 performs efficiently at room temperature, eliminating the need for heating during the pickling process. This feature allows for seamless integration into maintenance schedules without disrupting other plant operations.
10. Compatibility and Post-Cleaning Protection
The Cleanix B77 series—including B77, B77-RR, and B77-SR—is fully compatible, enabling users to mix the solutions for comprehensive descaling. Additionally, the Blasaver descaling agent completes the process by providing corrosion protection after the pickling solution is discharged, ensuring long-term equipment safety.
Usage and Dosage Guidelines
For optimal results, B77 is typically diluted to 5-15% of the total water volume after system isolation. Following descaling, using Chemmax’s Maxtreat 3006 N, Maxtreat 3028, and Maxgreen 3100 N helps to stabilize boiler alkalinity and prevent corrosion immediately after the cleaning process.
Chemmaxs technical team provides tailored solutions, conducting on-site surveys to develop the most effective and cost-efficient treatment program for each client. This customized approach ensures that B77 delivers consistent and reliable performance in a variety of industrial settings.
Risk Control: Ensuring Safe and Effective Descaling with Cleanix B77
1. Tube Perforation During Purging
Although B77 is designed to protect the parent metal, boilers with thick, long-standing scale deposits are at a higher risk of tube perforation once the inorganic scale is removed. Over time, scale can conceal underlying corrosion, and once the scale is gone, thin or weakened sections of tubing may be exposed and prone to failure.
➽ Recommended Action:
■ Inspection Plan: Conduct a thorough inspection of the boiler tubes before and after descaling to assess their structural integrity.
■ Replacement Readiness: Have a contingency plan in place to replace any compromised tubes immediately. This proactive approach minimizes downtime and prevents disruptions to production activities.
2. Tube Perforation After Purging
In water tube boilers, scale fragments that remain after initial cleaning can cause blockages and lead to localized overheating and tube breakage. Although B77 is formulated to limit the size of loosened scale fragments, certain fragments may still pose a risk if not properly managed.
➽ Recommended Action:
■ Thorough Cleaning: Perform a comprehensive flush and purge after the descaling process to remove any residual scale fragments.
■ Secondary Purge: If scale fragments persist, consider conducting a secondary purge using B77 to further "soften" and dislodge any remaining deposits.
■ Observation and Monitoring: Regularly monitor the condition of the boiler tubes and inspect for any signs of blockage or wear.
■ Replacement Plan: Prepare for potential tube replacement if structural integrity is compromised, ensuring minimal impact on operational continuity.
