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.
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.
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 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.
The purpose of this standard Test Method is to provide guidance on the testing and evaluation of coatings for aerospace applications. This Test Method has been developed for use by researchers, manufacturers, and organizations responsible for the manufacture, specification, and use of corrosion protective coatings for aerospace structures. The Test Method details measurement techniques to continuously monitor the combined environmental and mechanical effects that drive coating degradation in laboratory tests. While for many industries, judgements of coating performance may be primarily aesthetic, this Test Method describes direct, continuous measurements of coating degradation processes that are important to aircraft structural integrity.
This standard provides a method for collecting reproducible potentiodynamic data, enabling the comparison of data across various experiments and laboratories. This method is intended for those with experience in potentiodynamic data collection across all of industry and academia. This method has been adapted from Appendix B of MIL-STD-889. Users interested in submitting data for acceptance into MIL-STD-889 shall refer to the latest version of MIL-STD-889
This Technical Report provides sound technical information on the corrosion risk of exhaust gas scrubbers to ship owners, shipyards, marine engineers, scrubber designers and suppliers. Marine scrubbers used on ships are mainly wet scrubbers, which are open-loop, closed-loop, or hybrid types. Each system is discussed with respect to a description of each type of scrubber, washwater environments, materials of construction (metals and non-metals), pitfalls of inspection, fabrication, and welding of metals, service performance and applications history including descriptions of corrosion failures and successes, and repair and maintenance guidance.
