ER70S-6 Popular Filler was relative with 3 Standard and state A-No.1 1. AWS A5.18 2023 2. ASME BPVC Section IX 2023 3. NACE SP0472 2020 Reason from NACE SP0472 2020 Methods and Controls to Prevent In-Service Environmental Cracking of Carbon Steel Weldments in Corrosive Petroleum Refining Environments. Because it is impossible to perform production hardness testing on the root pass, the hardness test is usually waived even if a different filler metal is used for the root pass. However, to ensure that the root pass weld deposit is not hard, the same restriction to use only A-No. 1 chemical composition is specified following ASME Boiler and Pressure Vessel Code, Section IX. For more details, please see NACE SP0472.

Oil Storage Tank Welding Standards and Design Oil storage construction is governed by standards issued by the American Petroleum Institute (API) and the National Association of Corrosion Engineers (NACE).  The relevant API standards API 650, API 620, and API 12D respectively govern welded oil tanks, larger welded tanks with higher internal pressures, and the fabrication and erection of field-welded tanks used mostly in upstream production. These three standards cover the welding of oil storage tanks exhaustively.  The NACE MR0175 and MR0103 standards are only tangentially concerned with welding oil storage tankstheir primary concern is sulfide stress cracking in petroleum equipment in what is termed a sour environment. The terms sweet crude and sour crude refer to the hydrogen sulfide contents of crude oil from different sources. Sweet crude contains relatively little in the way of hydrogen sulfide and carbon dioxide, whereas sour crude contains high proportions of hydrogen sulfide and carbon dioxide which can heavily corrode steel. Because of this, NACE standards MR0175 and MR103 specify low carbon stainless steels, corrosion resistant alloys , and the cladding of steel pipes and valves with corrosion-resistant alloys. Welding these materials is considerably more difficult than welding carbon steels. The API standards are far broader, but tend to assume a sweet operational environment. The material they are most concerned with is high carbon steel that has been killed, in other words, thoroughly deoxygenated during forging. Since carbon steels are some of the most commonly welded types of metal, these standards are relatively straightforward and simple to meet. API 620 is the most demanding of these standards. It covers tanks operating with pressures up to 1,03 bar and at temperatures below 121 degrees C, with a focus on lap and butt welds.

* 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).

Valve and Flow Control Specialists distribute ASME 1 and ASME VIII Safety Relief Valves. No matter where you are on this planet we can assist you with these valves. (as requested reposted workplace health and safety) If your company has fired pressure vessels / boilers on site it maybe prudent to check your Safety Valves on the boiler and associated equipment. Fired vessels such as Boilers have strict codes of equipment and operational compliance. With noncompliance to local Codes now a criminal offence in many countries litigation there-after if any industrial issues occur it is very important to know the application, fit the correct valves and ensure checks and balances are covered. The onus of compliance sits squarely with the owner of the asset not the supplier or the maintainer although there maybe some consequence of association. Larger boilers will have flanged steel Safety valves. They can be in refineries, hospitals, food processing plants, sugar mills etc. These are more relevant to the ASME Sec 1 compliance requirements, many of which could have valves 20 to 50 years old still operating and being serviced. Our advice is check the last servicing, does the valve have the ASME Sec 1 “V” mark on the body? Is there a stamp affixed to the manufacturer's identity plate? If the valve does not have these markings and stamp you may wish to investigate. An ASME VIII (usually marked with a "UV") valve on a boiler does NOT comply to ASME 1 requirements. We think many will be surprised when they do check. A proactive boiler service company will ensure their clients asset is complying. Bronze valves can also come under the scope of ASME Sec 1 and is the most stringent code when used on boilers however sometimes there can be less demanding requirements in some countries with their own local codes.
