5.6.3 Leak test & water flushing description - Step 1 • LEAK TEST & WATER FLUSHING is the first step in preparation for chemical cleaning, to ensure that
the system to be treated is leak free after water flushing and prior to degreasing. It will also removes heavy deposits of oils, greases, soils or foreign matter other than mill scale, rust, or rust scale from internal surfaces of the piping system.
• This pre-cleaning shall be carried out by circulation method, using tap (potable) water. See Appendix 2 for typical layout of the system. During Step 1, no chemical shall be injected into the system.
• Piping to be cleaned will be disconnected or blanked off from mechanical equipment to prevent circulation of chemicals through bearings, cylinders, oil filter cartridges, instruments, screens and filters.
• Valves and equipment may be included in the circulation system, provided that their materials are resistant to chemical solutions involved and prior approval by customer (PTSC & BD POC) is obtained.
• During flushing, the system shall be packed with the water and no air shall be present in high points.
• Use naked eyes to check connection points in the circulation system and look for water leakage (step 1-3). The work shall be immediately suspended to correct any found leaking point. Soap water, dry cloth or similar aids may be used from outside connection points to assist leakage detection. During the flushing operation, if any leak is observed, remedial action shall be taken to stop the leak and flushing shall be continued until the visual inspection of outlet water indicates it has the same appearance of inlet water.
• During flushing, water flow velocity shall be kept within the range of 90 to 150 cm/s (3 to 4 ft/s), prefererably at 150 cm/s.

5.7.3 Degreasing description - Step 2
• DEGREASING WITH ALKALINE is the second step of chemical cleaning, to ensure that any remaining oil, or grease in the internal of the piping system (the test pack) is cleaned before Step 3 is commenced. All particles are further removed.
• The chemical used for degreasing has a mild foaming action, adapted to circulation treatment.
• After flushing the system and chemical bath tank with normal tap water (for carbon piping systems) or clean water of max. 20 ppm of chloride (for stainless steel piping systems), the temperature of the circulation water shall be raised by exchanging heat with a hot oil circuit to 40 - 60oC. This temperature shall be maintained throughout the treating process.
• Degreasing chemical shall be mixed into chemical tank (5 - 7%) and circulated through the system to remove grease and oil.
• Degreasing chemical: ALCA is a mixture of 10 - 25% potassium hydroxide (KOH), 2.5 - 10% diethanolamide of fat acids, 2.5 - 10% trisodium phosphate (MSDS and Data Sheets attached in Appendix)
• Treating duration shall be 2 - 4 hours
• A sample of the degreasing solution sample shall be tested every 30 minutes at the entrance and exit of the system. PTSC and BD POC representative(s) shall witness the analysis.
• Visual check: examination will be done by white light or using ultraviolet instrument and supplemented by wipe measure. The solvent will illuminate if it contains oil or grease (with ultraviolet).
• Step 2-5: neutralization to achieve pH 7 - 9 shall be by adding ALCA.
• Wipes will be kept as an evidence of the progress of the degreasing step.
• When the wipe test shows no traces of oil, the degreasing process is deemed completed.

5.8.3 Pickling description - Step 3
• PICKLING WITH ACID is the third step of chemical cleaning, to ensure cleaning of rust and scale without causing any damage to the circuit and specially valves, more sensitive to acid than the pipes.
• Prior to adding acid cleaning chemical, heated water shall be circulated (steps 3-1 and 3-2) in the system to re-check for any leakage on the flanges, temporary bypass hook-ups and all hose connections. All solutions during the recirculation sequence shall be filtered. Full flow filters or equipment shall be equipped with corrosion-resistant screens capable of removing particles that are 4 micrometers or more in diameter.
• Acid chemical must be tested on samples of pipes to see effectiveness of cleaning and protective againstfurther corrosion.
• Carbon steel piping systems: The chosen pickling product is ARA 400 (MSDS and Manufacturer Data Sheets attached in Appendix 1). ARA 400 consists of 2% glycolic acid, 2.5% citric acid, and 40% phosphoric acid. This product has a mild corrosive action, enough to remove remaining rust and scale without damaging pipe internal part. It also include a corrosion inhibitor (0.5%) and 1% non-ionic surfactant in order to ease the effect of the acids. Water used for Step 3 shall be clean tap water. Acid concentration is maintained from 5 to 7%. Neutralization to pH 7 - 9 shall be by adding ALCA (Step 3-5) of 2% concentration.
• Stainless steel piping systems: ARA 400 is also chosen for pickling of the stainless piping systems. Waterused for Step 3 shall be clean de-mineralized water containing maximum 20 ppm of chloride. The acidconcentration is maintained from 7 to 20%. Neutralization to pH 7 - 9 shall be by adding ALCA of 2%concentration (Step 3-5).
• Treating duration: 4 hours for carbon steel piping systems; 2 hours for stainless steel piping systems.
• Check frequency (Step 3-4): every 30 minutes.
• A sample coupon shall be placed inside the chemical mixing bath tank to evaluate the effectiveness of thecleaning process. Sample coupons shall be inspected after completion of each stage of the cleaning process.
1. The descaling solution sample shall be analyzed every hour. PTSC and BD POC representative shall witness the analysis process.
2. Check sample coupon effectiveness of cleaning.
• Wipes will be introduced at key areas in order to verify effectiveness of the descaling and de-rusted process. After one hour, 1 hour and half, two hours, three and four if necessary.
• Inspection of the test pack at the end of pickling process (Step 3-7) should look for the following indication of acceptance criteria for cleanliness at location of re-entry into pickling tank: cleanliness of 17/15/12 scale, ISO 4406:1999 (equiv. NAS 1638 class 6) for the treated piping systems. To confirm the effectiveness of the cleaning, the first test pack will be chemically cleaned with a pipe coupon installed (representing the actual pipe of the test pack). At step 3-7, this coupon will be removed from the cleaning circuit for checking of internal surface cleanliness.
• Important note: If iron content difference between beginning and during the pickling process (when testing is carried out, Step 3-4) exceeds 5,000 ppm (or 5,000 mg/L), the pickling shall immediately be stopped and the acid mixture be drained from the system followed by proper rinsing until pH of 7 - 8 is reached. Then the type and concentration of acids and inhibitor shall be changed. Approval of the change by customer representative shall be obtained prior to resumption of acid pickling. This situation rarely happens in practice with new piping systems.

• PASSIVATION / NEUTRALIZATION is the fourth step of chemical cleaning, to ensure:
1. That traces of chemicals used in previous steps are removed from internal surface of carbon steelpiping systems, or
2. That a passive protective layer of chromium oxide is re-created on the internal surface of stainlesssteel piping systems
• For carbon steel piping systems: ALCA of 2% is used to neutralize the remaining chemicals on the internal surface of the pipes.
• For stainless steel piping systems: As the passivation chemical, ALCA of 12 - 40% shall be used. This concentration is especially designed to passivate stainless steel.
