Chemical Cleaning
Chemical cleaning covers a wide range of services from new construction to ongoing maintenance activities.
Chemical cleaning is usually performed on process piping and equipment to remove deposits like scale, loose rust, waxes, paraffin, oils, dirt or any other foreign materials that could result in operating and maintenance problems. A newly built or operational plant requires chemical cleaning to remove all the rust to enhance the operation and heat transfer and to avoid any further corrosion in plant.
