Chemical Cleaning

Restore peak performance and maximize asset lifecycle through integrated chemical and mechanical solutions engineered for reliability, efficiency, and long-term operational integrity.

A Chemical Cleaning Service is a specialized industrial service designed to remove contaminants, deposits, and operational residues from process systems using controlled chemical and mechanical methods. The objective is to restore system cleanliness to specification, ensure operational integrity, and protect critical equipment from premature failure.

This service is commonly executed during commissioning, pre-commissioning, shutdown maintenance, or system restoration to eliminate contaminants such as mill scale, welding slag, rust, hydrocarbons, varnish, debris, and chemical residues.

Scope of Services

1. Hot Oil Flushing (HOF)

A high-temperature oil circulation process used to remove particulate contamination from lubrication and hydraulic systems. The process ensures system cleanliness meets required standards (e.g., ISO cleanliness codes) before commissioning rotating equipment such as turbines, compressors, and pumps.

2. Lube Oil Flushing (LOF)

A controlled flushing procedure using lubricating oil to remove solid contaminants from piping systems and reservoirs. This process safeguards bearings, gears, and precision components by ensuring contaminant-free lubrication systems.

3. Steam Blowing & Air Blowing

Mechanical cleaning methods that utilize high-velocity steam or compressed air to remove debris, welding residues, and loose particles from pipelines. These methods are critical for boiler systems, steam lines, and process piping prior to start-up.

4. Chemical Cleaning

A chemical-based treatment process that removes scale, corrosion products, oil, grease, and other deposits from pipelines, heat exchangers, boilers, tanks, and process equipment. Typically includes degreasing, pickling, passivation, neutralization, and preservation stages.

Purpose & Benefits

  • Achieves required cleanliness standards before commissioning
  • Protects critical rotating and static equipment
  • Prevents premature wear and system failure
  • Enhances operational reliability and efficiency
  • Extends asset lifecycle

Chemical cleaning services are essential in industries such as Oil & Gas, Power Generation, Petrochemical, and Heavy Industry, where system cleanliness directly impacts safety, performance, and long-term asset reliability.
