This joint standard practice details the use of blast cleaning abrasives to achieve a defined degree of cleaning of steel surfaces prior to the application of a protective coating or lining system. The focus of this standard is near-white metal blast cleaning, which removes all rust, coating, and mill scale when the extra effort required to remove all stains of these materials is determined to be unwarranted. The requirements presented include the end condition of the surface and materials and procedures necessary to achieve and verify the end condition. This standard is maintained jointly by the SSPC and NACE Task Group (TG) 006.
This standard covers the testing of metals subjected to tensile stresses for resistance to cracking failure in low-pH aqueous environments containing H2S. Carbon and low-alloy steels are commonly tested for EC resistance at room temperature where SSC susceptibility is typically high. For other types of alloys, the correlation of EC susceptibility with temperature is more complicated.
This standard practice details a procedure for electrical detection of minute discontinuities in new coating systems that are applied to conductive substrates. There are two types of testing equipment covered: low-voltage wet sponge testers and high-voltage spark testers. Electrical testing to determine the presence and number of discontinuties in a coating is performed on a nonconductive coating applied to a conductive substrate.
This standard explains the importance of pipeline electrical isolation in achieving and maintaining adequate, reliable, and economical corrosion control. The standard outlines the types of devices used for isolation; precautions to be observed; and selection of devices based on pipeline characteristics, site, and contents. The standard describes isolating flanges, gaskets, sleeves, washers, joints, unions, couplings, and spools, and discusses materials for pipeline casing isolation. Installation, field testing, and maintenance of isolating devices are also included. This standard is maintained by Task Group 539.
This standard establishes a test method for evaluating the resistance of pipeline and pressure vessel steels to HIC caused by hydrogen absorption from aqueous sulfide corrosion.
This joint standard covers the use of blast cleaning abrasives to achieve a defined degree of cleaning of steel surfaces prior to the application of a protective coating or lining system. The focus of this standard is commercial blast cleaning, which removes all visible oil, grease, dust, dirt, mill scale, rust, coating, oxides, corrosion products, and other foreign matter, leaving staining or shadows on no more than 33% of each unit area of surface. The requirements presented include the end condition of the surface and materials and procedures necessary to achieve and verify the end condition. This standard is maintained jointly by the SSPC and NACE Task Group 006.
This standard details a procedure for on-site measurement of the surface profile of abrasive blast-clearned steel surfaces that have a surface profile between 38 and 114 µm. Included is a description of the equipment required to perform the procedure, and two appendices detailing results of round robin testing and a statistical summary. This standard is maintained by Task Group 419.
This standard practice involves testing all pipeline coatings, including coatings on in-service pipelines and new or replacement coatings. High-voltage electrical inspection of pipelines coatings is one commonly used method in the detection of defects. Presented in this standards are acknowledged techniques for the use of holiday detectors currently used on pipeline coatings. A table of minimum testing voltages for various coating thicknesses is provided, as well as guidance for testing voltages, grounding, condition of coating surfaces, and care of equipment.
This standard establishes guidelines to prevent most forms of environmental cracking of weldments in carbon steel refinery equipment, including pressure vessels, heat exchangers, piping, valve bodies, and pump and compressor cases. Weldments are defined to include the weld deposit, base metal HAZ, and adjacent base metal zones subject to residual stresses from welding. It defines standard practices for producing weldments in P-No. 1 steels resistant to environmental cracking in corrosive petroleum refining environments.
