High pressure servo or proportional valved systems should have an I.S.O. 15/13/11 cleanliness standard. Cartridge and solenoid valved systems should have an I.S.O. 17/16/13 cleanliness standard.
During the fabrication, metal shavings and cutting oil may be left in the piping. Hydrocarbons react violently when they are exposed to oxygen which may lead to fire or explosion. Metal shavings and rust blooms are another source of ignition.
Water treatment is a process of continuously monitoring the integrity of an industrial water system. Different chemicals are added to the water to control calcium carbonate, iron and other elements Water treatment is expensive and is primarily used to slow down the inevitable build up of elements. Chemical cleaning is a more aggressive process that is designed to remove existing contamination in water systems. Strong concentrations of chemicals are circulated through the cooling systems. Most cooling systems can be cleaned and restored to optimal operating levels in 4-24 hours.
In most cases, the chemicals can be circulated through the main supply and return feeds. This allows us to clean the equipment in place and elimimnates disassembling the equipment.
Modern hydraulic systems are very sophisticated and their components are engineered to operate under precise conditions. Construction debris, slag or iron particles can potentially plug or scar various components. The down-time to replace a hydraulic valve can cost thousands of dollars. By chemically cleaning and oil flushing your hydraulics, the debris is removed from your piping ensuring a clean system.
Passivation is the spontaneous formation of a hard, non-reactive surface film that inhibits further corrosion.
Most pipe is made from recycled sources. It is typically ingrained with dissimilar metals from the melting and extruding processes. Dust, debris and other miscellaneous contaminants are also typically present on piping surfaces. These factors all lead to pre-mature corrosion. Passivation removes these impurities and creates a barrier that prevents corrosion.
We recommend the derouging and/or passivation of high purity steam and water systems annually.
Rouge is typically a red-brown ferric oxide found in WFI or steam systems. It can be easily removed. In severe cases, an oxide build-up may be present. This requires more aggresive cleaning procedures.
Gel Passivation is ideal for large stainless steel surfaces. A gel agent is added to the derouge or passivation chemical and is sprayed on the surface in need of passivation.
Most piping systems can be passivated in an 8-12 hour day. Larger piping systems may require additional time to set up hoses and equipment.
