Chemical Cleaning

Chemically engineered cleaning and passivation for heat exchangers, boilers and process circuits — removing the scale, deposits and contamination that throttle thermal efficiency, and preparing new systems for commissioning.

Chemically engineered cleaning and passivation for heat exchangers, boilers and process circuits — removing scale, deposits and contamination that throttle thermal efficiency, and preparing new systems for commissioning.

Acid Cleaning (scale, rust, and mineral deposit removal)

Alkaline Cleaning (grease, oil, and carbon deposit removal)

Solvent Cleaning (organic contaminants, oils, waxes, coatings)

Degreasing

Passivation (stainless steel and corrosion-resistant alloys)

Pickling (surface preparation for steel and stainless steel)

Biocidal Cleaning (biological contaminant removal and prevention)

Oxidation Cleaning (disinfection and stain removal)

The result: Restored heat-transfer efficiency, prevented corrosion, extended asset life, and equipment ready for inspection, coating, or return to service.

Capabilities

What We Do

Heat Exchanger Cleaning & Descaling

Priority: Highest frequency — mandatory for operational efficiency
Scale, fouling, and deposit build-up on heat exchanger surfaces is one of the most common and costly problems in petrochemical, power generation, and pulp & paper plants. Chemical descaling restores heat transfer efficiency without costly equipment removal or replacement. A non-negotiable maintenance requirement across all of SJA's target clients.

Boiler Chemical Cleaning

Priority: Shutdown-critical — tied to planned maintenance cycles
Industrial boilers accumulate scale, iron oxide deposits, and corrosion by-products that reduce efficiency and create safety risks. Chemical cleaning — using alkaline degreasing, acid descaling, and passivation sequences — is performed during planned shutdowns to restore boiler performance and extend service life.

Pipeline & Piping System Flushing

Priority: Pre-commissioning & maintenance critical path
New and existing pipelines require chemical flushing to remove mill scale, weld slag, construction debris, biological growth, and hydrocarbon residues before commissioning or after extended downtime. Includes alkaline flushing, acid pickling, and inhibitor passivation to protect pipe internals from corrosion.

Degreasing & Surface Preparation

Alkaline or solvent degreasing of metal surfaces prior to inspection, coating, or repair. High demand in fabrication and maintenance environments. Include if SJA delivers this as a standalone service – Write more content for landing page Claude

Vessel, Tank & Reactor Chemical Cleaning

Priority: Shutdown-driven — high value per job
Storage vessels, reactors, and process tanks require periodic chemical cleaning to remove hydrocarbon residues, polymer build-up, scale, and biological contamination. Chemical cleaning reduces confined space entry requirements and minimises the volume of waste generated compared to manual cleaning methods.

Pre-commissioning Chemical Cleaning

Priority: Project-phase — high margin, builds long-term relationships
New plant, equipment, and piping systems must be chemically cleaned before start-up to remove fabrication residues, protective coatings, and contamination that would damage process equipment or contaminate product. Includes flushing, degreasing, pickling, and passivation as a complete pre-commissioning package.
