REPAIR OF DAMAGED GALVANIZED
Cold Galvanized repairs in gratings, galvanized pipes external will be performed according to
the following procedure:
-
Flaked or delaminated areas to be removed by means of a scraper up to bare metal. All
loosely adhering paints must be remove.
-
After al flaked film has been removed; oil and grease must be removed by emulsion
cleaning or by suitable detergents. Remove zinc salts and other soluble salts by high
pressure fresh water hosing. (Zinc salt may also require scrubbing with nylon or wire
brush to remove.)
-
When the surface is dry, feather edges to sound and intact paint. Roughen the adjacent
areas of the existing paint by coarse sand paper to ensure inter-coat adhesion.
-
Remove dust completely on all surfaces to be painted before the application.
-
The surface must be completely dry and clean with the temperature above the dew
point to avoid condensation.
-
Check surface preparation, microclimate condition and other requirements prior to
paint application to ensure proper application condition is observed at all time (surface
temperature, dry and wet bulb temperature, relative humidity, dew point temperature,
etc.).
-
Observe proper and correct mixing ratio as indicated in the Product Data Sheet as well
as proper application equipment. Mix the paint of corresponding base and curing agent
as per the mixing ratio required. Stir the mixed paint thoroughly by means of a clean
mechanical mixer a homogenous mixture is obtained.
-
Apply zinc rich epoxy primer at specified wet film thickness corresponding to the
required dry film thickness. Normal range dry is: 40-80 micron.
-
Allow the coating to be fully dry/cured after completion of paint application. Provide
adequate ventilation as necessary to facilitate proper drying/curing.
8. SURFACE PREPARATION
Surfaces contaminated by oil and grease shall be solvent cleaned according to SSPC SP 1
prior to any blast cleaning.
Blasting abrasive quality shall be according to SSPC AB 1, SSPC AB 2, or SSPC AB 3, as
applicable.
Abrasive material for blast cleaning, consisting solely of steel shot shall not be used for
surfaces to be coated with inorganic zinc-rich primers or fusion-bonded epoxy coatings. A
mixture consisting of steel shot and at least 25 percent (wt.) steel grit is acceptable.
SSPC SP 11 is suitable surface preparation for small repair areas or for field welds where
SSPC SP 10 or better had been originally specified and/or performed. SSPC SP 11 provides

Inorganic zinc coatings exposed in a severe industrial environment shall be top
coated with system aa, ep, or uu as deemed most appropriate by the Owner’s
Engineer for the local site conditions and service environment.
(2) This system must be heat cured. Small items may be baked in an oven to obtain
cure but with larger pieces of equipment, this heat cure normally takes place as the
equipment is put into high temperature service.
(3) *If thermal spray aluminum is specified, the Owner’s Engineer shall specify the
sealer, if one is to be Used.
(4) *Coating suitable for expected temperatures shall be specified
(5) VENDOR’s requirements and SSPC PS GUIDE 8.00 shall be followed when applying
topcoats to inorganic zinc rich primers.

11. INSPECTION AND TESTING
Surface preparation cleanliness shall be evaluated using SSPC VIS 1 or SSPC VIS 3 visual
Standards.
Surface roughness (anchor pattern or profile) shall be determined according to NACE RP0287
or ASTMD 4417. This shall be performed on all items before application of prime coat.
Dry film thickness measurement shall be made of each coat and of the total system, according
to the procedure established by SSPC PA 2, with the exception that the inspector may inspect
any and all areas and make as many measurements as deemed necessary. Any items which are
not acceptable to the inspector and/or the OWNER'S ENGINEER shall be repaired immediately
and approved before application of subsequent coatings. Inspector shall notify Engineer of any

13. PIPING AND TANKS IDENTIFICATION
During the work on the plant, a label sing should be painted with the name of the fluid, the pipe
diameter and the pipe specification plus the arrow indicating the direction of flow. In insulated
piping, the labeling will be done on the jacket that covering this insulation.
The distance between labels shall be as agreed between the Contractor and the Owner based
on the Construction best practices within the process units, as well as applicable specifications
and codes.
Moreover, pipe racks, provided it is legible (first level), tracks and large section are labeling in
each interference, cross road and battery limit with a maximum of 50 m unlabeled in free
straight sections, whenever legible (in elevation racks are not applicable). It will also be labeled
in ascending and descending pipe rack sections.
The labeling will be black letter on white background. The flow indicative arrow’s size shall be
proportional to the size of the letter and the diameter of the pipe. The size of the letters will
be made according to the dimensions indicated in the following table, being the type of letters
according to the Owner indication:
Table 5 – Letter size according to diameter of the pipe
O.D. Piping
Letter Size
¾” to 1 ¼”
1 ½” to 2”
2 ½” to 6”
8” to 10”
More 10”
½” aprox.
¾” aprox.
1 ¼” aprox.
2 ¼” aprox.
3 ½” aprox.
In addition, in the case of hazardous fluids (type M), that are identified in the Plant; a yellow
ring shall be painted next to the label. The ring width shall be the size of the letters of the label.
Project Specification TAL‐GEN‐MET‐SPE‐0001 be follow for identification and labeling of new
and existing storage tanks ones that change of service.
