6.4 SURFACE PREPARATION6.4.1 Abrasive Blast CleaningWhen surfaces are to be prepared by abrasive blasting, Equipment name, Tag-No and other identification plates shall be suitably masked-off to prevent damage during the blasting process. Valve spindles, grease nipples and other mechanical parts sensitive to abrasion or damage by blasting will be similarly protected. Grit containing water-soluble elements shall not be used. After blasting, the treated surface finish shall be inspected to ensure that it complies with SSPC-SP 10 (SSPC VIS 1) or SA 2.5 (ISO 8501-1), with grade D, C, B, and grade A respectively.

a) Surfaces to be painted shall be cleaned in accordance with SSPC-SP 1, SSPC-SP 2, SSPC-SP 3, or SSPC-SP 10.b) Cleaning and painting shall not be carried out together in the same area nor shall blast cleaning not to be carried out in the proximity or recently applied paint.c) In performing the surface cleaning, particular attention shall be paid to joints, angles, pits, and weld areas to ensure that their surface is brought to the required standard.d) After cleaning, all dusts, sand and grits shall be removed from pockets and corners using vacuum cleaner or dry compressed air or clean brush. Dust cleanliness level for blast cleaned surfaces shall be inspected in accordance with ISO 8502-3 and dust acceptance level shall be rating 3 maximum.Between cleaning and priming, the steel shall not be allowed to be contaminated in any way and all surfaces shall be primer coated before discoloration occurs. Application of the prime coat painting shall normally be made over a cleaned area within maximum four (4) hours after completion of cleaning. If any rust bloom does form, surface shall be cleaned again, before application of the prime coat.e) After sandblasting process, above ground surface must be clean by steel shot and steel girts blasting.

6.4.2 Abrasive MaterialAbrasive agents for cleaning shall be sharp, angular, clean, dry and free of contaminants. Expandable abrasive material shall not contain more than 2 percent by weight of ferrous oxide (Fe203) or cuprous oxide (CuO). The abrrasive shall be of a suitable size to produce the required cleanlines and surface blast profil. Silica sand, mixture of chilled iron shot and steel grit may be used. Meta!lic abrasive material shall conform to SSPC - AB 2 and SSPC - AB 3. Recycle iron shot and steel grit may be used after the materials screened and checked for cleanlines and for Silica sand shall not be used recycle.

When using mechanical cleaning tool, Equipment Name, tag-Nos, and other identification plates shall be suitable masked-off to prevent damage during cleaning. Valve spindle, grease nipples and other mechanical parts, sensitive to abrasion or damage by power cleaning, shall be similarly protected. Mechanical cleaning shall be preferably performed by disc sanding. Rotating wire brushes shall be avoided (at least as final cleaning) in order not to polish the surfaces.

6.4.4 Galvanized Steel and Aluminum SuriacesGalvanized metal or aluminum surfaces shall not be painted unless when specified. The surfaces shall be cleaned with mineral spirits to remove dirt, grease, oil, and factory film, and wiped dry in accordance with SSPC-SP 1. Water-based cleansers may be used or galvanized surfaces only. Deposits on weathered metal shall be removed by wire brushing in accordance with SSPC-SP 2 or SSPC-SP 3 before painting. In addition, surfaces shall be etched with a commercial solution of chemical phosphoric metal etch, rinsed with water and allowed to dry prior to painting. Steel surfaces coated by hot-dipped galvanizing that have areas showing poor adhesion or areas damaged during shipment or construction shall be cleaned by abrasive blasting, wire brushing or another mechanical means conforming to SSPC-SP 2 or SSPC-SP 3. These areas shall be recoated with an inorganic zinc (i.e., cold galvanizing) material to yield a dry film thickness (OFT) of minimum 150 microns. Inorganic zinc coating application shall be as per Manufacturer procedure recommendation.

6.4.5 Primed Steel SurfacesPrimed steel surfaces shall be cleaned of dirt, grease, oil, rust, mill scale, and other deleterious materials. When primed surfaces have been subjected to welding, all flux slag deposits, welding flux fume deposits and oxides formed by welding shall be removed 20 centimeters from the weld area by abrasive blasting, wire brushing, or for another mechanical means conforming to SSPC-SP 2 or SSPC-SP3. This procedure also applies to the repair of shop-primed surfaces damaged during shipment or construction.
