4 HIPS Pipe Fabrications was established in 2005, and from this point we have been actively involved in numerous RO, purified & WFI water systems. Our RO systems have been installed in many of the NHS hospitals across the UK and Ireland. These systems have been for Sterile Services, Endoscopy and Renal Dialysis. The latest install was for a Pex pipework system for Sunderland Royal Hospital 800 meters in total. Our Pharmaceutical sector have installed purified water systems for Novartis, GSK and MSD, accompanying these systems were full IQ documentation. All pipework is boroscoped and in house passivated

HIPS Pipe Fabrications 5 When stainless steel is subjected to any heat process welding or machining the material looses properties within the infra structure of the metal. The chromium content is decreased and positive irons are deposited onto the welded or machined surface. This welded or machined area of the stainless steel will be prone to corrosion (rust). The only way to overcome this problem when working with stainless steel and heat is to passivate the system. There are several theories as to how the stainless steel should be passivated. The original concept was to firstly degrease the pipe using Potassium Metasilicate or Potassium Hydroxide (Caustic) at a 1% solution to volume. This technique will disperse any grease or foreign bodies from the material. This system is still the best way forward. The second step in the process is to introduce an acid compound to the material to increase the oxidisation and restore the chromium element of the stainless steel. In the past Nitric acid at 40% volume was considered the only way to perform the passivation of the metal. The problem with this is that Nitric Acid is a hazardous material and requires a permit to dispose of the effluent. This can be expensive and in today’s carbon foot print life style a no no. A more efficient process is to use Citric acid. This process is more environmentally friendly and more efficient in the passivation process. The normal percentage to volume is 15% at a temperature of 20 0 C to 40 0 C. The disposal of the effluent is to drain, to decrease the PH of the citric acid caustic can be added until PH is 7, this makes the effluent harmless to the environment. Using citric acid will decrease costs and work with any Environmental Company Policy. The final process is to determine if the passivation has worked. There are several processes that can be used. Using a salt spray onto the material and left for 24 hours, brown rust marks will appear if positive irons are present. A Ferroxyle test can also be used, this is not advised on food and beverage processes, the test solution consists of Potassium Ferricyanide and Nitric acid. This compound then becomes Cyanide. In the past we have introduced a spool piece within the system to be passivated with the major pipework. This spool piece is submitted to the ferroxyle test away from the work place and disposed of. HIPS undertake stainless steel passivation on site and at our work premises, we have a purpose built skid unit and baths which can perform the passivation of the pipework, and smaller spool pieces can be soaked in a bath solution. Full certification will be supplied for all passivation to FDA standards STAINLESS STEEL PASSIVATION
