AMPP SP21507-2022, Standard Practice for Sandwich Plate Repair of Steel Structures

Product Number: AMPP SP21507-2022

Publication Date: 2022

$109.00

Oil and gas industry onshore and offshore drilling, production, storage, and transportation generally experience very corrosive environments. Even though corrosion prevention systems, such as cathodic protection, protective coatings, and liquid/vapor phase inhibitors are usually used for corrosion protection, severe corrosion of the structures is still unavoidable without effective corrosion protection and appropriate corrosion management. The repair of degraded structural members having substantial corrosion damage is critical for maintaining structural integrity for safe and continuous operations.

This standard practice formalizes a methodology of steel sandwich plate repair technology. This methodology uses a new steel plate or prefabricated structural component laid on top of the existing steel plate to be repaired. An elastomer core is used to bond the new plate/component and the existing steel plate to form a steel sandwich plate structure, thereby repairing the existing steel substrate without it being cut and replaced. This method is intended to restore the strength of the damaged structural members, or to reinforce existing structures.

AMPP SP21511-1-2024, Laser Ablation for Surface Preparation of Ferrous Metals, Pulsed Laser

Product Number: AMPP SP21511-1-2024

Publication Date: 2024

$109.00

This AMPP standard, designated AMPP SP21511-1, is intended to enable specifiers to develop project specification re- quirements and end users to achieve the required level of surface preparation or cleanliness using pulsed laser ablation (PLA). For the purpose of this standard, PLA employs pulsed, Q-switched laser technology.

PLA is a media-free, commercially available process that uses high-intensity directed energy in the form of a collimated, monochromatic, pulsed, focused, and scanned laser beam to remove coatings, oxides, contaminants, and hazardous materials (HAZMATs). This process is also referred to as laser ablation coating removal (LACR). PLA may be used to prepare coated or uncoated ferrous metal substrates before the application of a protective coating or lining, or it may be used in conjunction with other surface preparation methods. PLA offers environmental, health, and safety (EH&S) ben- efits as well as a level of precision that cannot be achieved with other surface preparation technologies. This standard is intended to be used by corrosion control professionals in civil infrastructure, defense, nuclear, petrochemical, auto- motive, aerospace, and other related industries. It is for use by coating specifiers, engineers, contractors, inspectors, and others who are responsible for defining a specific level of surface cleanliness or producing a post-laser treatment surface condition specified, using PLA technology.

PLA can remove 100% of existing coatings. However, it is most effective for applications requiring less than 95% of coating removal (by surface area of exposed substrate) when prescribed by appropriate Technical Authority guidance.

The primary functions of PLA cleaning applications are:

a) To remove material from the surface that can cause premature failure of the new coating system. Paragraph A1 of Appendix A (nonmandatory) provides additional information.

b) To enhance the adhesion of a new coating system.

c) To expose the surface profile of the substrate that is underneath the existing coating, rust, other corrosion products, or other contaminants and,

d) To reduce or remove nonvisible contamination that may be present on the substrate. Examples include thin films of oil and grease, and soluble ionic materials such as chlorides, ferrous salts, nitrates, and sulfates. PLA can reduce or completely remove water-soluble contaminants as well as fixed, non-smear- able low-level radiological contamination.

AMPP SP21513-2021, Procedure for Determining Conformance to Concrete Surface Profile Requirements

Product Number: AMPP SP21513-2021

Publication Date: 2021

$109.00

This standard describes a procedure suitable for laboratory and field use to determine conformance to specified surface profile on concrete substrates using Method 1: Depth micrometer as described in ASTM D8271, Method 2: Concrete Surface Profile (CSP) Chips (CSP 1-10) as described in ICRI Guideline No. 310.2R, or Method 3: Replica putty as described in ASTM D7682 (Method 3A-visual or Method 3B-quantitative).

Proper bonding of coatings and linings to concrete surfaces requires proper cleaning and frequently requires the concrete to be roughened to increase the surface area. The roughness, also known as surface profile, can be imparted into concrete by abrasive or water blast cleaning, acid etching or various impact/scarifying power tools. The resulting surface profile depth can influence coating/lining adhesion and performance. Coating/lining manufacturers and/or facility owners frequently specify cleaning and roughening of the concrete surface prior to product installation.

AMPP SP21520-2023, Acceptance Criteria for Cathodic Protection of Steel in Concrete Structures

Product Number: AMPP SP21520-2023

Publication Date: 2023

$109.00

Historically, NACE SP0290, NACE SP0216, and NACE SP0408 included sets of criteria that needed to be satisfied to indicate that a cathodic protection (CP) system is delivering adequate current to passivate the reinforcing steel or reduce its corrosion current to low and non-destructive levels. These criteria were mostly the same, so the aim of this standard is to set out the essential criteria that each one of the above standards must satisfy in a single document. This allows each of the above standards, which deal with different applications of cathodic protection, to concentrate and expand on aspects that are specific for each application. This standard further suggests techniques that can be employed to estimate the level of protection achieved by a non-compliant cathodic protection method.

AMPP SP21523-2022, Non-thermal Plasma Surface Preparation of Metals

Product Number: AMPP SP21523-2022

$109.00

This standard contains the general requirements for the safe and effective use of APC equipment, operated either manually hand-held or through use of automation, to prepare various metallic surfaces for maintenance, repair, recoating, or lining. This standard does not address surface preparation of concrete.

APC is applied to the entire surface specified to be prepared for a new coating or lining. Poorly adhered surface material and coating that cannot withstand the APC process are removed, while, depending on the chosen cleanliness level, any remaining coating is suitably prepared prior to the application of a new coating layer over the existing. In the case of metallic substrates, the underlying surface profile will be revealed whenever surface contamination and coatings are removed.
