SAES-H-001 Coating Selection and Application Requirements for Industrial Plants and Equipment

Maintenance Coating/Painting: Application of coating to preserve the useful state of an existing coating. Repairing is the most common method to maintain a coating. Complete replacement of an existing coating is not maintenance coating.

Medium Corrosive Atmosphere: Urban and industrial atmospheres with moderate sulfur dioxide pollution, identified as Mildly Corrosive as per Table 1 of SAES-A-134.

New Construction Coating: Application of coating on a completely new and uncoated facility, equipment or machinery. New coating also applies to the coating application on completely bare substrate that was previously coated.

Thick Film Coating: Coatings with an average dry film thickness greater than 20 mils (500 microns).

Thin Film Coating: Coatings with an average dry film thickness of 20 mils (500 microns) or less.

Thixotropic Coating: A type of coating that thickens or gels in a relatively short time when at rest, but readily becomes more fluid when agitated or stirred.

Stripe Coat: A coat of paint applied only to edges or to welds on steel structures before or after a full coat is applied to the entire surface. The stripe coat is intended to give those areas sufficient film build to resist corrosion.

Sweep Blast Cleaning: A fast pass of fine nonmetallic abrasive blasting pattern at low pressure (< 275 kPa / 40 psi) over a surface to remove loose material and to roughen the surface sufficiently to successfully accept a coat of paint. This method of cleaning is specified as SSPC-SP 7, Brush-off Blast Cleaning, or as SSPC-SP16, Brush-Off Blast Cleaning of Coated and Uncoated Galvanized Steel, Stainless Steels, and Non-Ferrous Metals.

Ultra-High Pressure Water Cleaning: Removal of surface contaminants (cleaning) by jetting with water at a pressure in excess of 25,000 psi (170 MPa).

Vessels: Where referred to in this standard, the term “vessels” includes, but is not necessarily limited to columns, traps, drums, heat exchangers, and boilers.

Wet-on-Wet Coating Application: Technique of coating application where additional coating passes are employed over a coating that is still wet, making the composite film dries as a whole. A wet coat applied over another wet coat is considered one coat of application.

brushing and blowing down with clean, dry compressed air. Internal surfaces shall be dry brushed and vacuum cleaned.

6.6.2 Abrasive-cleaned surfaces shall be primed or coated before the surface

condition degrades below the specified cleanliness level.

6.6.3 Abrasive blasted surfaces shall call for inspection prior to priming or

coating if the surfaces are hold for more than 4 hours after blasting.

6.6.4 The reference standard for profile measurement shall be the Replica

Tape Method according to ISO 8503-5. This does not preclude the use of other techniques provided that these give similar measurable profile values in microns. Surface comparators are not acceptable.

6.6.5 Ultra high pressure water jetting (cleaning) is acceptable for the surface

preparation of previously blasted equipment in accordance with SSPC- SP WJ-1/ NACE WJ-1 and SSPC-SP WJ-2/ NACE WJ-2. Waterjetting cleaning does not create profile, it only exposes the pre-existing profile.

6.6.6 Wet abrasive blasting can be used where abrasive blasting is not

permitted because of the risk of damage to process equipment. The cleaned surface shall be dry at the time of painting.
