PROTECTIVE COATINGS SPECIFICATION
FOR EQUIPMENTS, PIPING & STRUCTURES
6.2.2 Shop Priming Coats
The use of temporary or holding shop primers shall not be
employed, all coatings applications applied at shop shall be in
strict accordance with the requirements of the painting Schedules
A, B, C.
Should vendor’s items be required to employ a temporary/holding
shop primer for transit requirements, all works shall involve the
complete removal of the shop primer and coated to the required
ADGAS Painting Specification prior to installation at site.
N.B: It should be noted that the responsibility of quality assurance
and control rests first and for most with the vendor.
The absence of an ADGAS approved inspector does not in
any way relieve the vendor of any QA/QC obligation.
6.2.3 Site Preparation
Site preparation shall consist of one or a combination of the
following:-
(a) Surface cleaning shall remove all surface contamination
including dirt or grease in accordance with SSPC-SP1
(solvent cleaning and high pressure sweet water washing
with emulsified cleaning agents).
Potable water used for cleaning shall have a chloride
content of less than 30ppm.
Prior to blast cleaning, steelwork shall be dressed, so all
weld splatter and laminations etc. should be removed by
grinding.
SOP 022 Issue-1 Revision 11 Page 22 of 101
PROTECTIVE COATINGS SPECIFICATION
FOR EQUIPMENTS, PIPING & STRUCTURES
(b-1) Blast cleaning to ISO 8501-1-1988 (05 5900/BS 7079). Due
care shall be exercised to prevent other areas and wet
painted surfaces from contamination. Contractors shall
erect necessary screens around the work area to prevent
contamination. Abrasive shall not be allowed to enter the
inside of equipment and piping.
Natural Garnet is the only acceptable substance to be used
with a particle size of between 0.85 and 0.5mm. This can be
used for both carbon and stainless steel equipment and pipe
work.
Before any blasting occurs in a site location the enclosed
form Appendix D must be filled in and signed by the
appropriate personnel responsible. This is in line with
ADGAS Standing Instruction No. H-10-1.
(b-2) Where blast cleaning to Sa 2,5 (near white metal cleaning) is
not advisable due to substrate excessive corrosion, portable
spot blast cleaning equipment with straight bore nozzle
operating at lower pressure (less than 50 psi) can be used.
Spot blast equipment with straight bore nozzle to be kept
far away from the substrate (more than two foot distance.)
while Carrying out SWEEP blast cleaning.
(c) Power tool cleaning using impact tools, rotary wire brushes
and flap discs.
(d) Hand cleaning by scraping or wire brushing.
(e) It should be noted, that mechanical or hand cleaning must
be considered marginal as this method of surface
preparation will not remove mill scale, rust or provide a
surface profile/anchor pattern.
(f) Ultra High Pressure Water Jetting (with or without
abrasive) - at pressure up to 25,000 to 30,000 psi shall only
be considered for use on site pending full ADGAS approval.
6.2.4 Nuts and Bolts
Surface preparation shall be directed to achieve the same standard
as the adjacent surfaces.
6.2.5 Aluminium Surfaces
No preparation or painting is required.
SOP 022 Issue-1 Revision 11 Page 23 of 101
PROTECTIVE COATINGS SPECIFICATION
FOR EQUIPMENTS, PIPING & STRUCTURES
6.2.6 Galvanized Surfaces to receive paint
Surface preparation shall consist of thoroughly degreasing and
treating with a mordant solution (comprising of a phosphoric acid
solution incorporating copper salts in a solvent/water solution-‚T‛
wash or similar).
After the reaction period the surfaces shall be cleaned with potable
water.
Note: Weathered galvanized surfaces should be wire brushed or
blast cleaned if required, first to remove all corrosion
products.
6.2.7 Weld areas and difficult corners
All weld seams, sharp edges and surface irregularities shall be
contoured and surface irregularities ground smooth as required.
Stripe coating shall be required to all subsequent coats including the
primer, and shall be applied by brush to physically wet in the
substrate, particularly the weld seam.
6.2.8 Site Preparation of Shop Primed Surfaces
Site preparation shall first consist of thoroughly degreasing followed
by the cleaning method as described in section 6.2.2 to remove all
loose shop priming paint and to prepare the surface to the condition
specified. Temporary/holding primers shall be completely removed
and re-worked in accordance with the paint schedules prior to
installation on site.
6.2.9 Agreed Standard of Surface Preparation
For blast cleaned surfaces the contractor shall use the colour
photographic standards as ISO-8501-1, 05 5900/BS 7079 (1988).
For power tool and hand tool cleaning the contractor shall use the
colour photographic standards for hand cleaning ISO 8501-1: 1988 05
5900/BS 7079 (1988) Part-1.
SOP 022 Issue-1 Revision 11 Page 24 of 101
PROTECTIVE COATINGS SPECIFICATION
FOR EQUIPMENTS, PIPING & STRUCTURES
6.2.10 Surface Profile
‘
The surface profile after blast cleaning shall have a min/max height of
50/75 microns for carbon steel and a min/max height of 30/50 microns
for stainless steel (as measured by surface replica technique -
TESTEX).
6.2.11 Rogue Peaks
These may be defined as peaks of exceptional height in the blast-
cleaned surface, which may not be indicated by the normal methods
of surface profile measurement.
The presence of rogue peaks may be demonstrated by:
Viewing the surface through an illuminated magnifier.
Rubbing lightly over the surface with a clean cotton glove. Care
must be taken to ensure that no cotton fibers remain on the steel.
The presence of ‘rash rusting’ on the primed surface, due to the
peaks not being coated with primer.
If rogue peaks are found, they may be removed by lightly
scuffing the surface with emery paper, a metal bar or, preferably,
by hand. It is essential to check that all dust and other
contamination is completely removed after the sanding operation,
also that the operation has been successful in the removal of the
rogue peaks.
6.2.12 Soluble Iron Corrosion Products (Soluble Salts)
When rusted steel has been blast-cleaned and is acceptable to a Sa3 or
equivalent visual standard, it is still probable that the surface is
contaminated with ‘soluble iron corrosion products’ (‚Soluble Salts‛).
SOP 022 Issue-1 Revision 11 Page 25 of 101
PROTECTIVE COATINGS SPECIFICATION
FOR EQUIPMENTS, PIPING & STRUCTURES
Care shall be taken to determine the presence of ‚Soluble Salts‛ and
their adequate removal shall be in accordance with tests described in
BS 5493: 1977: Appendix G Test for detecting soluble rust producing
salts remaining on blast cleaned steel. Refer to Painting Inspection
Procedure, item 3.4.1 (Sheet 2 of 5).
6.2.13 Treatment of Mechanical Damage to Furnished Painted Items
Where the substrate has been exposed, by mechanical damage, the
area shall be re-prepared to the original standard and coated with the
specified system to restore the full film thickness. The surrounding
50mm (2 in) of sound paintwork shall be lightly blasted or abraded to
provide a firm key.
Where very small areas of such damage occur in otherwise sound
coatings, hand or power driven tools may be used to prepare the
exposed substrate.
Repainting shall completely cover the prepared surface and the
surrounding 50mm of intact paintwork.
Areas which have been damaged without exposing the substrate
shall be washed with proprietary detergent solution and rinsed with
fresh water. This shall be followed by abrading the area of damage
including the first 50 (2 in) mm of surrounding intact coating. The
relevant intermediate and finish coats as shown in the painting
schedules shall then be applied in accordance with this specification.

preparation has been carried out and before any deterioration of the
specified standard has occurred. Irrespective of this, the following
maximum time limits are required.
(a) Blast cleaned surfaces, shop and site, within 4 hours.
SOP 022 Issue-1 Revision 11 Page 29 of 101
PROTECTIVE COATINGS SPECIFICATION
FOR EQUIPMENTS, PIPING & STRUCTURES
(b) Power tool and hand tool cleaned surfaces, within 12 hours.
7.7 Over coating
Where possible the subsequent application shall be applied over the
priming paint as soon as the primer is dry and hard enough to receive the
next coating and in general guidance from Manufacturers data sheets.
Before application of the next coating the contractor shall ensure that the
previous coating is thoroughly dry and clean from all harmful matter, such
as grease, oil, dust, etc. Swab samples of the surface may be taken at the
discretion of ‚Company‛.
7.8 Contrasting Colours
Where it is necessary to apply more than one coat of a particular
paint to obtain a specified dry film thickness, then the first coat shall
be selected sufficiently different in colour, in order to distinguish
from the next and subsequent coats.
7.9 Bolted connections
Shop bolted connections shall be prime coated and brought together
whilst the paint is still wet. Bolted connections using high strength
friction grip bolts shall not be painted and the contractor shall ensure
that all surfaces for these bolts are adequately masked off before
painting. The size of masking shall be a minimum of 25mm greater
than the connected surface.
7.10 Stripe Coating
Stripe coating shall be required to all welds, bolts, nuts, angles and
sharp edges to all subsequent coats including the primer prior to
spray coat application to maintain dry film build.
7.11 Cold Applied Tape
Cold Applied tape wrappings shall be applied in full accordance with
the manufacturer’s recommendations.
SOP 022 Issue-1 Revision 11 Page 30 of 101
PROTECTIVE COATINGS SPECIFICATION
FOR EQUIPMENTS, PIPING & STRUCTURES
Tape wrapping shall be applied over the compatible primer coat in a
continuous overlapping spiral with a minimum overlap of 50% and
with sufficient tension to provide good adhesion without wrinkling
or necking of the plastic carrier. The tape shall begin and terminate
in a square end, such that all of the substrate is covered by a double
thickness of tape. The tape shall be applied in such a manner that it
does not bridge discontinuities in the surface of the substrate. Where,
surface discontinuities cannot be accommodated by the tape without
bridging, and then the surface shall be profiled with compatible
moulding putty, before tape application. The moulding putty shall
be specifically formulated for this purpose and obtained from the
same manufacturer as the tape.
Where piping emerges from the ground the tape wrapping shall
extend 18‛ (450mm) above ground and overlap the above ground
painting system by a minimum of 4‛ (100mm). Finish shall be Off-
white or Light Grey for U.V. resistance.

7.13 Surface Preparation
Surface preparation shall include the removal of all rough weld
capping and surface laminations, and profiling of all sharp edges,
corners etc. followed by dry abrasive blasting to the standard in
SCHEDULE ‘C’.
7.14 Extent of Coating
The lining shall extend over the total internal surface including the
bore of nozzles and over the faces of all flanges, unless the latter are
weld overlaid with corrosion resistant alloy (CRA), in which case the
lining shall terminate on the CRA. To ensure correct sealing, glass
flake coatings on flange faces shall be press moulded or machined
that after fully curing.
Where sacrificial anodes are installed, care shall be taken to minimize
damage to the coating at the attachment points and to ensure that the
active surfaces of the anodes are not coated.
The lining shall be inspected for any irregularities such as raised
areas, pinholes, soft spots, disbandment, discontinuities and
delaminations. The final inspection shall include electrical
discontinuity testing over 100% of the coated surface in accordance
with NACE RP-0188-90. All indicated coating holidays shall be
thoroughly investigated and all defective coating removed and
replaced fully in accordance with the requirements of this
specification. The electrical discontinuity test shall be repeated over
all repaired areas.
7.15 Repairs to Glass Flake Linings
Any pinholes located by high voltage holiday detection,
delaminations, soft spots or other coating defects shall be ground out
and fresh lining material applied, with each coat of the repair
material overlapping the surrounding intact material by a minimum
of 25mm.
