* A NACE Compliant Valve: QRC Valves: https://lnkd.in/d4iCSXG7 In the world of industrial valves, selecting the right choice for your specific application is crucial to ensure optimum performance. One key factor in this decision-making process is the compliance with industry standards like NACE (National Association of Corrosion Engineers). This article reviews requirements for a NACE compliant valve, then summarizes some key elements of the MR0175 and MR0103. What is a NACE Compliant Valve?: A NACE compliant valve is one with a design that meets requirements as per NACE MR0175/ISO 15156 and NACE MR0103/ISO 17945. Meeting these requirements makes them capable of withstanding corrosive environments, especially sour service. The term “sour service” refers to corrosive environments where there is exposure to a relatively high percentage of hydrogen sulfide (H2S). In such environments, hydrogen atoms can preferentially seep into hard materials like high-strength metals and heat affected zones (HAZs) that have not been stress-relieved. As hydrogen builds up in these materials, there is a corresponding pressure build up, resulting in cracks and eventual failure. This phenomena is referred to as hydrogen induced cracking (HIC), and in the presence of stress, the failure could be by sulfide stress cracking (SSC).

CUI get worst when pipeline operate at low temperature, material are prone to Embrittlement/Brittle fracture. API and NACE code provides guideline from insulation removal to inspection,mitigation and box up but still control of corrosion under insulation is a challenging task because it can originate at those parts where you expect least. Some of important references when dealing with CUI Identification of susceptible and critical points as per API 574 & API 583 Insulation removal & Inspection of areas at damage and non damage insulation as per API 570 table 02 Damage mechanisms as per API 571 Injection and mixing point inspection for refineries as per NACE SP 0114 Surface preparation for NDE as per NACE No 02 SSPC SP-10 Removal of scale on live equipment and removal of insulation at susceptible points on live line is a risky task Despite being of various advancements CP systems, different coating techniques CUI is a challenging moreover interesting task to deal with.Behavior of corrosion and damage mechanisms are different at elevated and at lowest temperatures. Corrosion is a slow poisoning to equipment as it deteriorates material, reduces integrity and provide basis for equipment failure. Providing appropriate design, selection of accurate material & insulation, adoption of methods as per frequencies and environment,Root cause analysis, frequent monitoring tend to control corrosion at higher extent. #api570 #API583 #nace #asnt #ansi #corrosionprotection #corrosion #corrosionprevention #refineries #oilandgas #oilindustry #petrochemicalindustry #refineries #inservice #inspection #inspectors

Lessons Learned during 10 Years of External Corrosion Direct Assessment (ECDA) Application - NACE Conference Paper No. 5601 some important highlights from this valuable paper: 1-Use the right number of ECDA regions based on corrosion risk and reliability of the indirect inspections tools.  2-Selecting the ECDA regions may have a significant influence on the final number of digs and ultimately on the cost of the project. The best way to select the “right” number of regions is to assess the pre-assessment data in terms of risk of corrosion and accuracy of indirect inspection tools. Should a region have a significantly higher risk of corrosion or should the indirect inspection tools become “less reliable”, a new region would typically be required.   3-The sound engineering practice beyond the NACE Standard SP0502-2010 facilitates using the ECDA approach in other integrity assessments.  4-ILI and ECDA may be used not only alternatively, but they may also be used interactively to optimize each individual process. 

API 570 is a standard developed by the American Petroleum Institute (API) that outlines the requirements for inspection, repair, alteration, and rerating of in-service metallic piping systems used in the petroleum and chemical process industries. #This_standard #applies to piping systems that have been in service and are subject to corrosion, cracking, or other damage that may affect their integrity. The purpose of API 570 is to ensure that these piping systems are maintained and operated in a safe and reliable manner. #NDT #DT #QUALITY #ASME #inspection #casting #calibration #welding #QC #AQ #ASTM #APi #ASNT #STANDARD #PT #UT #VT #MT #RT #corrsion #WPS #PAUT #PQR #defect #stainless #stress #ASTM #APi #ASNT #STANDARD #vessels

The standards #ASME PCC-2 and #ISO 24817 set out the requirements for #engineered #composite #repairs. Providing repairs that comply with these requirements enables the operator, supplier, and regulator to have confidence in the solution provided. However, the detailed requirements need expert assessment and understanding to be implemented as intended. Playing an integral role in writing and developing both ASME and ISO standards since their inception, we have built our process to do just this. Our in-house controls provide an auditable approach allowing us to demonstrate compliance of repairs installed with the governing standards while allowing operators to continue to work safely. We manage the entire process of supplying the repair so that operators only have one point of contact.
