Degreasing and Passivation of Stainless Steel


In the past number of years pharmaceutical, electronic and food processing firms have insisted that all new stainless steel piping and equipment should be degreased and passivated after installation. This work is commonly included as part of the mechanical installation contract. In order to compete for this type of business, mechanical engineering contractors often find themselves having to provide this service, which is not part of their regular business.
 

Though not a complex process in itself, the procedures required for this work are complicated by the following factors:

• This is often a once off process, requiring the use of temporary equipment and piping.
• There are a number of safety issues that will need to addressed. The chemicals and the temperatures required for the procedure, makes the process potentially hazardous.
• Clients often demand a rigorous testing procedure.
• Often the design of the piping, makes the design of logical cleaning circuits a difficult process.
• Disposal of spent reagent chemicals and rinse water is often a problem.

Water Technology Limited have been involved in this type of activity for over ten years, and have tackled project both on site, and at our premises in Togher, Cork.

• Equipment
  Our portable equipment is designed to access difficult areas, enabling us to confine the procedure to the area immediately around the equipment being treated.
• Planning and Safety
  We have the expertise to handle the most complex of cleaning procedures, safely and efficiently. From the project planning right through to the disposal of the used chemicals. We can advise on the safety measures that are required to ensure that the procedures can be handled as safely as possible.
• Safety
  Safety considerations are always a priority with this type of operation. Water Technology Limited have a number of procedures designed to reduce the risks involved as much as possible. We can provide chemicals in pre-diluted form. Our equipment enables us to confine the operation to the area immediately around the equipment involved and we have the necessary equipment to deal with possible chemical spillages quickly and efficiently.
• Monitoring and Documentation
  Our experienced staff can handle any of the chemical analysis requires to ensure that the correct chemical conditions are maintained for the duration of the procedure. Full documentation can be provided as required by the client. To view a typical passivation certificate click on the following link.
