When all HAZOP studies and CSBP Design Reviews have been completed and the P&ID’s are at astage where they have been “frozen” the Contractor shall:

a. Review and mark up P&ID’s to determine extent of each Test Pack and to define totalnumber of Packs.

b. Determine which vessels can be pressure tested “through” and which cannot (review 70%rule and confirm that structure/ foundations have been designed to accommodate the weightof water filled lines and vessels).

c. Consider flanging of vessel nozzles to simplify testing work.

d. Rationalise Piping system test pressures to minimise the total number of Test Packsrequired as a result of maximising test limits.

e. Prepare a master set of colour coded P&ID’s to identify Test Packs and boundaries.f. Revise the Line List to reflect rationalised test pressures.

g. Revise the Line List to include a Test Pack Number against every line.

6.

If parts of a line are not accessible without setting up special access such asscaffolding, then only new, modified or repaired piping, valves and fittings need tobe made accessible for the test for purposes of inspection.

7. If the pressure during a hydrostatic test cannot be maintained due to a pre-existingpassing or leaking valve or fitting, or an inability to fully vent the system, then thetest may be passed by continually pumping up the system to test pressure andinspecting the area of new work for leaks. The Superintendent should perform anassessment of any leaks from existing valves and fittings to see if maintenancerectification work is required. The Superintendent shall arrange for rectification of leaks or passing from new items.

8. Water analysis for water used for hydrostatic tests of austenitic stainless steel linesis not required if CSBP site supplied demineralised water is used.

6.5 SYSTEM DRYING

After hydrostatic testing of the system is complete and approved, all lines and equipment shall becompletely drained of the test fluid. Piping systems vents shall be opened while draining to avoidvacuum. Special attention shall be given to points where water may be trapped, such as in valvebodies or low points.

An air compressor designed to deliver high volume dry air shall be connected to the system highpoint(s). Air shall be blown continuously until all water has been driven out and theSuperintendent accepts the system.

The only exception to this requirement shall be cement-lined pipe, which must be kept in a wetcondition to prevent deterioration of the lining, or if the Superintendent advises that air-drying isunnecessary. An example of when the Superintendent may advise that air-drying is unnecessary iswhen the fluid to flow through the piping is compatible with water, the water is not going to effectany equipment supplied through the piping, and the line is unlikely to suffer from oxygen/watercorrosion between the test and when it is commissioned (e.g. stainless steel lines, very short timeperiod between end of test and commissioning for carbon steel lines).

6.6 CHEMICAL CLEANING OF PIPING SYSTEMS

Chemical cleaning shall not be considered a substitute for line flushing and shall only be performedwhere specified by the Superintendent. Where a piping system is to be chemically cleaned it shallhave previously been flushed, tested and blown dry. Drying may be deferred only if chemicall i i t i di t l f ll h d t t
