Chemical Cleaning & Passivation

Our chemical cleaning services ensure new and existing piping systems achieve the highest levels of cleanliness, performance, and compliance. We deliver pre-commissioning and maintenance cleaning solutions aligned with ASTM A380 guidelines, removing oils, weld oxides, heat tint, and process contaminants through controlled cleaning, descaling, and passivation. For pharmaceutical systems, all new and modified installations are cleaned and passivated in accordance with ASME BPE requirements, supported by comprehensive QA, documentation, and validation.

Our capabilities include:

• Pre-commissioning chemical cleaning of new piping systems (ASTM A380 aligned)

• Passivation and decontamination to restore corrosion resistance and product integrity

• Scheduled maintenance cleaning of existing piping to remove fouling, scale, and residues

• Pharmaceutical-grade cleaning in accordance with ASME BPE standards

• Hot and cold chemical cleaning processes, with strict control measures to maintain temperature, concentration, and circulation conditions

• Closed-loop chemical circulation cleaning, ensuring effective cleaning of complex and inaccessible systems

• Customised SOPs, tailored to meet specific client, site, and regulatory requirements

• Contaminant investigation and chemical analysis, enabling development of targeted cleaning procedures for unknown or complex contamination issues

By combining proven industrial cleaning methodologies with flexible, client-focused delivery, we ensure your systems are clean, compliant, and ready for reliable operation.
