1.0 SCOPE

1.1 This specification establishes the minimum requirements for shop priming and painting for the different areas within the project. The specification scope covers the surface preparation, priming, and painting of engineered equipment, tanks, vessels, and shop fabricated structural steel, piping and plateworks at Las Bambas Project for Xstrata Tintaya S.A.

The terms "Shop Priming" and "Painting" define the extent of the Seller's painting responsibility prior to his release of the equipment to the Buyer. The term "shop" does not limit the work location to the Seller's shop, since the work may be performed at a subcontractor's or supplier's facility under the Seller's shop control. However, this specification does not apply to field painting at the jobsite.

1.2 The following surfaces shall be prepared and painted by Seller in accordance with the Coating Schedule (section 7.0 of this Specification), unless otherwise noted:

1.2.1 Structural and miscellaneous steel items, including ladders, platforms, handrails, beams, columns, stairs, clips, brackets and supports.

1.2.2 Exterior surfaces of carbon-steel tanks, vessels, platework, exposed ductwork, apparatus and piping unless noted below.

1.2.3 In general, all exposed non-machined surfaces of carbon steel or cast iron.

1.3 Machinery, motors, electrical and control panels, valves, and equipment may be prepared and painted according to Manufacturer's standard procedures, if those procedures provide a coating system suitable for the intended service conditions, as determined by Buyer.

1.4 The following surfaces shall not be painted:

1.4.1 Nonferrous metal such as aluminum, copper, or brass.

1.4.2 Stainless or alloy steel.

1.4.3 Glass, tile or ceramic surfaces.

1.4.4 Valve stems, rotating shafts or other machined contact surfaces.

1.4.5 Inside surfaces of chutes, launders, vessels, apparatus and piping except where specified.

1.4.6 Inside surfaces of carbon steel storage tanks, except where specified.

1.4.8 Areas within 2 in. of surfaces to be welded after coating.

1.4.9 Nameplates.

1.4.10 Non jacketed elastomer insulation.

1.4.11 Instruments.

1.4.12 Steel Structures Embed (shear key).

1.4.13 Plates for slip critical joints.

1.5 All surfaces not being painted as listed in the preceding paragraph shall be kept entirely free of paint and protected from damage during surface preparation and painting operations.

2.0 CODES AND STANDARDS

2.1 The quality of items and services shall meet the requirements of this specification, the applicable codes and standards, and project procurement documents. If these requirements conflict with Seller’s normal procedures, the former shall govern.

2.2 The galvanizing applicator shall be a galvanizing specialist with experience in the

application of zinc coatings by the hot-dip method. The work shall result in galvanized surfaces free of blisters, bare spots, flux, ash inclusions, and other evidence of poor workmanship.

5.3 Where abrasive blast cleaning is specified, prepared surfaces shall be painted before any visible rusting or other deterioration of the surface occurs. Abrasive blast cleaning shall not be permitted when surfaces are less than 3°C (38°F) above dew point, or when the relative humidity is greater than 90%.

5.4 Abrasives used for blast cleaning shall be clean, dry and free of oil or other contaminants. The particle size shall be capable of producing the specified anchor profile. Recycled sand and cast iron or malleable iron shot shall not be used.

5.5 Surface profile shall be measured in accordance with the requirements of ASTM D4417.

5.7 Prior to abrasive blast cleaning, oil, grease and other contaminants shall be removed by solvent cleaning in accordance with SSPC-SP-1.

5.8 Burrs, slivers, scabs and weld spatter visible after blast cleaning shall be removed, and repaired areas shall be reblasted to specification.

5.9 The compressed air system used to prepare the substrate and apply coating materials shall be as follows:

5.9.1 Air supply lines shall be equipped with effective traps to remove moisture and oil.

5.9.2 Prior to using compressed air, the quality of the air downstream of the separator shall be tested by blowing the air onto a clean white blotter or cloth for two minutes, in accordance with the requirements of ASTM D4285, to check for any contamination, oil, or moisture. This test shall be performed at the beginning and end of each shift and at not less than four-hour intervals. The test also shall be made after any interruption of the air compressor operation or as required by the Buyer. The air shall be used only if the test indicates no visible contamination, oil, or moisture. If contaminants are evident, the equipment deficiencies shall be corrected and the air stream shall be re-tested. Separators shall be bled continuously. All lines shall be tested individually prior to use.

6.8 Galvanizing:

6.8.1 Galvanizing shall be performed only after the section to be galvanized is completely assembled. Assembly of sections to be galvanized shall be to the largest section that can be hot-dip galvanized. Components of bolted assemblies shall be galvanized separately. Edges requiring field welding shall be protected from galvanizing for a distance for 25 mm (1 in.) from the edge.

6.8.2 Precautions outlined in ASTM A385 to obtain high quality galvanized coatings shall be observed. It shall be Seller’s responsibility to safeguard against embrittlement and warpage. Potential problems that require a design modification shall be brought to Buyer’s attention before proceeding

6.8.3 Steel surfaces other than bolts, nuts, and washers, shall be hot dipped galvanized in accordance with ASTM A123 to obtain a minimum of 1.0 oz of zinc on each galvanized surface. This will provide a DFT of 43 microns (1.7 mils) for the zinc coating.

6.8.4 Nuts, bolts, washers, and miscellaneous steel hardware shall be hot dip galvanized in accordance with ASTM A153. Female threaded openings shall be re-tapped after galvanizing. Bolts and other items with male threads shall not be re-tapped.

6.8.5 Fabricated assemblies shall be totally immersed in the zinc bath. Dipping of assemblies in more than one operation is not allowed.

6.8.6 Zinc coatings shall be free of voids, blisters, flux spots, inclusions, dross, acid, and black spots. The zinc shall be well adhered to the steel so that it may not be removed during normal handling and erection activities. Lumps, globules, or heavy deposits of zinc that could interfere with the assembly operation or the part’s intended use are not allowed.

6.9 Coatings, other than galvanizing, shall be free of runs, sags, voids, drips, over-spray, loss of adhesion, blistering, peeling, flaking, mudcracking, or inadequate cure. Defects shall be corrected as they are detected during applications.

6.10 Inorganic zinc prime coats shall be tested for hardness and adequate cure by the following method. After the primer has been allowed to cure for re-coating in accordance with the manufacturer's latest published instructions, the surface of the primer shall be scratched with the edge of a coin held at an approximate 60 to 70° angle to the surface, using moderate force. When properly cured, the inorganic zinc primer shall show a metallic sheen where the surface was scratched and no more than a very small amount of zinc powder shall be removed from the coated surface.

6.11 Coated and galvanized items shall be stored off the ground and protected from damage during lifting or handling. Non-abrasive supports shall be used for shipment and storage.
