The original Def Stan was adopted as an AMPP standard under the provisions of the AMPP Standards Committees Operating Manual Procedures for Conversion of Government Agency Standards.
This standard is a guide to corrosion protection against atmospheric corrosion and covers all aspects from the basic mechanisms of aqueous corrosion, though a summary of the differing types to a detailed review of aspects of atmospheric corrosion. It concludes with a detailed survey of the methods of control against corrosion and a focused description of the particular methods of corrosion protection for different metals and alloys.
This standard is intended for use by corrosion control personnel, design engineers, project managers, purchasers, and construction engineers, and managers. It is applicable to underground steel pipelines in the oil and gas gathering, distribution, and transmission industries.
This standard describes methods for qualifying and controlling the quality of fusion-bonded epoxy (FBE) pipe coatings, urethane coatings, epoxy-urethanes, shrink sleeves (special applications), two-part liquid epoxies, and other properly qualified coatings (as long as the proper parameters are met in accordance with this document, e.g., polyolefin, three-layer coatings), provides guidelines for the proper application, and identifies inspection and repair techniques to achieve the best application of plant- and field-applied coating systems.
This document discusses the issues to be taken into consideration with respect to accounting for corrosion on steel piles in non-marine applications. The rate of corrosion, design life and methods of corrosion control are discussed in a manner to provide the reader with guidance as to how to proceed with determining these factors. This standard is applicable to pipe piles, sheet piles, H piles, and other steel piles.
This standard practice describes overcoating of the exteriors of railcars. The purpose of this standard practice is to provide methods for testing and application of overcoating materials for the benefit of railcar owners, lessees, and maintenance providers who are charged with developing and executing programs for the maintenance painting of railcars.
This AMPP standard practice presents guidelines and minimum requirements for citric acid based passivation of marine storage tanks to identify good cleaning practices and improve corrosion resistance. This standard is intended for use by shipboard personnel, ship owning organizations, commodity owners, tank readiness surveyors, chemical producing organizations, ship surveyors and other stake holders.
Biofouling accumulation on a ship’s hull has a direct impact on fuel consumption and associated greenhouse gas (GHG) emissions and may pose a biosecurity risk due to the presence of non-indigenous, potentially invasive aquatic species.
The antifouling system (AFS) is designed to protect the underwater surfaces from biofouling accumulation. Underwater inspections (UWI) of ships are typically carried out to monitor and verify the condition of the underwater hull and the AFS.
Recipients of UWI reports are reliant on the quality of information provided to make adequate decisions relating to hull performance, AFS condition and performance, biofouling management and associated risk assessments. Consistent and good quality reporting is key to effective underwater hull condition record-keeping and management.
This standard is based upon the technical requirements for coating repair developed by the National Marine Ship Standardization Technical Committee Ship Repair Branch Technical Committee in China, but may be applicable for use globally provided it meets the field requirements of marine maintenance and fulfills the environmental protection requirements of the appropriate governing body.
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.
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.
This standard practice presents guidelines for preplanning for, recovering from, and repassivation after a low pH excursion in open recirculating water systems, no matter what the cause. The procedures presented in this standard inno way preclude the use of other procedures but are presented as best practices developed over years of experienceinavarietyofplants.Theprovisionsofthisstandardshouldbeappliedunderthedirectionofqualifiedwater-treatmentpersonnelfromwater-treatmentsuppliersand/orconsultants andplantpersonnel.
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.
This standard is intended for use by coating or lining specifiers, applicators, inspectors, or others who require the use of pressurized water cleaning technology to achieve a defined level of visual cleanliness of concrete surfaces. This standard contains requirements for Thorough Cleaning. Requirements for Light Cleaning are addressed in a separate standard.
