Special caution shall be taken not to contaminate stainless steel surfaces close to where the work is being carried out, especially if halogenated cleaning agents are being used.

5.2.2 Contamination by Salts, Acids and Alkalis

Residue from chemical products shall be removed by washing with warm water or jet blasting (700 bars). Neutral moisturizing agents may be used if necessary. Clean wet surfaces shall be between 6 and 8 pH.

5.2.3 Rust Removal

Paint shall be applied to surfaces, at maximum, eight (8) hours after rust removal. In no case shall clean surfaces be left overnight without being painted. In the event that rust reappears on any surface, it shall be sand blasted again.

5.2.3.1 Abrasive blasting

Rust shall be removed by abrasive blasting, in accordance with the SSPC-SP standard corresponding to the cleaning grade established for the selected painting system. After preparation, the appearance of the surface must coincide with the corresponding figure in ISO-8501 standards.

Blasting shall not cause surface damage or distortion.

The abrasive to be used shall be clean, dry and free of contaminants and soluble salts and shall conform to applicable SSPC-SP and ISO 8501 standards.

Blasting of areas in contact with demineralized water shall be performed with steel shot and not with sand, to prevent contamination of surfaces with silica.

The grain size of the abrasive shall be within the margins indicated in the standards specified and shall be such that surface roughness after blasting is that recommended by the paint manufacturer, which is normally between 25 and 50 m depending on the thickness of the paint to be applied.

After blasting, surfaces shall be cleaned of dust by blasting with air free of oil and water or by suction and/or brushing.


Rev. 2457-01-I-M-27700-R2



17 deof

37

Surface preparation by wet blasting may be used in certain environments at the discretion of the Engineer, in order to provide increased safety against sparking, to minimize atmospheric and surface pollution or to prepare surfaces which are salt contaminated and spent much of their time in wet conditions. Wet blasting shall be confirmed as suitable by the Manufacturer of the paint that is to be applied to the surface.

Compressors shall supply air free of oil and water, with the necessary flow and pressure in the nozzle.

5.2.3.2 Manual or Mechanical Brushing

This method shall be used only where blast cleaning is impractical and with the approval of the Engineer, for repairing and patching up small damaged areas. Final surface appearance shall be equivalent to cleaning grade of standard ISO-8501 specified in each case.

This method shall also be used to obtain adequate roughness on cold-rolled steels.

5.2.3.3 Chemical Cleaning

The removal of rust using chemicals (pickling, etc) shall be subject to the explicit approval of the Purchaser.

5.3 PAINTED STEEL SURFACES

5.3.1 Surfaces with Defects

If the defects to be repaired cover small zones, they shall be brushed with a mechanical brush down to a firmly adhered coat of paint or, if there is no such coat, down to the bare metal. The dust resulting from brushing shall subsequently be cleaned, followed by the painting system specified.

If the defects to be repaired cover more than 20% of the painted surface, or are spread throughout the surface (regardless of the %) all the layers of defective paint shall be completely removed and the surface shall be prepared and completely painted in accordance with this specification.

5.3.2 Weld Areas and Screw Joints

All weld joints shall be continuous; if this is not possible, the gaps will be sealed with repaintable acrylic or polyester resin filler on both sides of the joint, as long as they are accessible.

After welding, the area shall be cleaned of grease and brushed before painting. Care shall be taken to ensure the complete removal of weld splatter, test fluid residues, burnt paint, etc. The surface affected by the weld shall be left prepared to be completely painted like the rest of the component.

For bolted or screw joints and after fastening the joints, all the perimeters of the joint will be sealed with repaintable, acrylic, or polyester resin filler, compatible with the coat painting.

In this type of joints, the use of paints that plastifies with pressure, used as lubricants is not permitted.

5.3.3 Surfaces Free of Defects

If these surfaces have to be painted, the painted surface shall be cleaned with cloths or brushes using solvents suited to the already applied paint. If the type of paint is not known, tests shall be carried out on small surface areas with different solvents or detergents until it can be established which of them leaves the surface clean without affecting the coating. Very smooth surfaces will have to be lightly shotblasted or brushed to obtain adequate roughness for the paint to adhere. Once the surface is clean and dry, the specified coats of paint shall be applied.

5.4 GALVANIZED STEEL

5.4.1 New Galvanized Surfaces

These surfaces shall be cleaned with a suitable detergent and subsequently washed with water. Solvents may have to be used to remove oil and grease.

Very smooth surfaces will have to be lightly shotblasted or brushed to obtain adequate roughness for the paint to adhere and then, following approval, epoxy primer with accredited adherence to galvanized surfaces or similar product will be applied.

5.4.2 Aged Galvanized Surfaces

All contaminants and reactive products shall be cleaned from zinc surfaces with water and detergents. After cleaning and following approval, epoxy primer with accredited adherence to galvanized surfaces or similar product will be applied.

5.4.3 Zinc Surfaces with Bare Patches

These surfaces shall be cleaned locally by light shotblasting (or brushing), taking care not to remove too much of the zinc coating from areas adjacent to those that have to be repaired. After cleaning, a coat of zinc epoxy primer shall be applied to the surface.

The rest of the surface must also be painted with zinc epoxy primer before proceeding with the finishing painting for the specified system.

5.5 COLD ROLLED STEEL

5.5.1 For thicknesses > 3 mm, an abrasive blasting up to a grade of Sa2 according to ISO 8501 will be performed.

5.5.2 For thicknesses 3 mm, degreasing and phosphating will be performed, completed by a light shotblasting to obtain adequate roughness for the paint to adhere, if needed.

5.6 STAINLESS STEEL AND LIGHT ALLOY

5.6.1 If these materials have to be painted, it shall be performed as follows:

Degreasing by washing with water and neutral detergent, brushing with non-metallic brush, if needed, to eliminate any type of contamination.

Afterwards, light shotblasting, preferably with corundum or glass sphere, will be performed. Otherwise, very fine and dry silica (silica not allowed on surfaces in contact with process fluids) sand will be used. After shotblasting, the surface will be vacuumed to remove residues. The average roughness shall be in the interval 15-30 m.

5.7 CONCRETE AND CEMENT SURFACES

5.7.1 General

5.7.1.1 New concrete and cement surfaces shall be left to cure for at least thirty (30) days before they are painted.

5.7.1.2 Before painting, it shall be verified that there is no filtration and moisture that prevent good adherence of the paint. If there is any filtration or moisture, the paint manufacturer shall recommend a compatible sealant coat that can be applied until the surface is saturated before painting.

5.7.1.3 Before applying the paint, the Supplier shall ensure that it is compatible with the stripping products used.

5.7.1.4 Before cleaning the surfaces, all burrs, worn or protruding edges, etc, shall be made good with the use of mechanical polishers, abrasive discs, etc.

5.7.1.5 Before applying coatings to vertical panels, walls, pillars, etc, all defects such as pitting or blistering shall be repaired to obtain an even coat free of pores and cracks. It is essential that a compatible filler or mortar be applied which covers the surface but does not sink so that, once it is dry, it can be worked with a polisher.

5.7.2 Cleaning

5.7.2.1 Gentle shotblasting should be used to clean concrete and cement. All dust should subsequently be removed by suction or air blasting.

6.13 INTUMESCENT PAINT

6.13.1 General

Intumescent paint is a product whose dry film reacts to a heat source, producing an increase in volume of said film, in the form of foam, which acts as a heat insulation layer protecting the substrate from the heat during a certain length of time.

The time that a load-bearing structure complies with its function without collapsing in the event if fire is called fire stability (EF). The "fire stability" period for a structure depends on the thickness of the intumescent paint system and on the shape of the structure.

6.13.2 Intumescent System

Intumescent systems should also guarantee anticorrosive protection of the steel structure.


Rev. 2457-01-I-M-27700-R2



29 deof

37

An intumescent system is comprised of one layer of anticorrosive primer, one layer of an intumescent paint and one topcoat layer.

The topcoat is a protective sealing layer that can be applied over the intumescent paint to protect it against humidity and the atmosphere and that can also have a decorative function.

An intumescent paint system shall be applied to those surfaces of load-bearing structures that require a 60 minute fire stability (indicated in the corresponding technical specification).

The intumescent systems used must comply with the requirements below, said requirements being certified by the appropriate authorities:

a) Fire stability, EF-60 min., determined with EN-ENV 13381-4:2005 ("Test method to determine the contribution to the fire stability of structural elements, through the application of protection to the steel structural elements") or another similar internationally recognized standard for the applied thicknesses. The thickness of the system is considered to be the sum of the primer, intumescent and topcoat film thicknesses.

b) The anti-corrosive primer should be combustible but not flammable. It should be compatible with the intumescent paint.

c) The topcoat should be combustible but not flammable. It should be compatible with the intumescent paint and should not impede the development and consequent expansion of the foam in the event of fire.

6.13.3 Shape factor or Massivity

The thicknesses of intumescent paint to be applied are determined as a function of the shape factor or massivity of the structure to be protected, which is defined as being the ratio between the perimeter of the section exposed to fire, expressed in meters, and the area of said steel section, expressed in square meters.

Massivity (m-1)= )(m section steel of Area

(m) section steel of Perimeter2

The bigger the massivity of the steel section, the higher the thickness of the dry film required to obtain a certain stability against fire.


Rev. 2457-01-I-M-27700-R2



30 deof

37

The definition of intumescent paint systems for each component will be provided by the paint manufacturers based on their commercial products, their experience in this field and the requirements of this specification.

The Supplier shall send the documentation associated with the system: surface preparation procedures, paint system definition, application procedures, retouch and repair procedures, paint data sheets, etc.

The Supplier shall send the Purchaser all the certificates and tests which certify that the paint complies with the required stability against fire.

The Purchaser will not accept the paint if the documentation has not been previously approved.
