🎯 What are engineering codes and standards?
Engineering codes and standards are sets of guidelines and rules that are used to ensure the safety, reliability and performance of engineered systems, such as fire and life safety, electrical systems and mechanical systems.

🎯 What is the difference between code and standard in piping?
Codes usually set forth requirements for design, materials, fabrication, er****on, test, and inspection of piping systems, whereas standards contain design and construction rules and requirements for individual piping components such as elbows, tees, returns, flanges, valves, and other in-line items.

🎯 Why are codes and standards important?
Codes and standards establish minimum acceptable levels of safety, quality, and reliability. Understanding the codes and standards at both the industry and government level will allow you to better understand the expectations of your chosen field.

🎯 Is ASME a standard or code?
ASME is the leading international developer of codes and standards, hereafter referred to as standards, associated with the art, science, and practice of mechanical engineering. ASME is the globally recognized, trusted source of consensus standards

🎯 What are the standards used?
A standard is a document that provides requirements, specifications, guidelines or characteristics that can be used consistently to ensure that materials, products, processes, and services are fit for their purpose. (International Organization for Standardisation).

🎯 What is API and ASME?
The ASME, or the American Society of Mechanical Engineers, provides codes that govern the safety of mechanical equipment. These codes are meant to provide overarching specifications for mechanical engineering applications. The API, or the American Petroleum Institute, on the other hand, produces recommended guidelines.

🎯 What are engineering ISO standards?
ISO standards are internationally agreed by experts. Think of them as a formula that describes the best way of doing something. It could be about making a product, managing a process, delivering a service or supplying materials – standards cover a huge range of activities.

🎯 What is the difference between code and standard in ASME?
Codes are generally accepted sets of rules that tell you what you need to do. Standards provide the “how to” of executing codes. Specifications, unlike codes or standards, outline the requirements of a specific company or product.

🎯 What is ISO vs ASME?
For example, ASME uses inch-based units, fractional dimensions, and bilateral tolerances, while ISO uses metric units, decimal dimensions, and unilateral tolerances.

🎯 Is it ASME or ANSI?
ASME is an accredited Standards Developing Organization that meets the due process requirements of the American National Standards Institute (ANSI). Standards that are developed under an accredited program may be designated as American National Standards.

Non-conformance reports (NCRs) are essential tools for identifying and addressing deviations from requirements, procedures, or standards. Here are some tips to help you write an impactful NCR:

1️⃣ Clearly Identify the Non-Conformance: State the specific requirement, procedure, or standard that was not met. Provide all relevant details to ensure clarity and understanding.

2️⃣ Refer to Supporting Evidence: Include tangible evidence such as photos, documents, or records that demonstrate the non-conformance. This helps substantiate your claim.

3️⃣ Determine the Root Cause: Analyze the situation to identify why the non-conformance occurred. Was it due to inadequate training, equipment failure, or process issues? Understanding the root cause is crucial for implementing effective corrective actions.

4️⃣ Describe the Impact: Explain the consequences of the non-conformance on the product, process, or system. Highlight any scrap, rework, or other significant effects to emphasize the importance of addressing the issue.

5️⃣ Recommend Corrective Actions: Offer specific and actionable solutions to fix the immediate issue and prevent its recurrence. Be thorough in your recommendations to ensure a comprehensive resolution.

6️⃣ Record Relevant Details: Include essential information such as the date, location, individuals involved, and relevant part or asset numbers. These details provide context and aid in tracking and addressing the non-conformance.

7️⃣ Specify Resolution Timeline: Outline both short-term containment actions and long-term preventive measures. Set realistic completion dates for each action to ensure accountability and timely resolution.

Refers to the formation of cracks in a welded joint after a certain period of time following the completion of welding.
These cracks typically occur in the heat-affected zone (HAZ) adjacent to the weld.

𝗗𝗲𝗹𝗮𝘆 𝗖𝗿𝗮𝗰𝗸𝗶𝗻𝗴 𝗣𝗿𝗲𝘃𝗲𝗻𝘁𝗶𝗼𝗻:
► 𝙋𝙧𝙚𝙝𝙚𝙖𝙩𝙞𝙣𝙜 the base metal before welding can reduce the cooling rate and minimize the risk of delay cracking.
The preheating temperature should be based on the material and thickness being welded, as specified in welding codes or recommendations.

► Using 𝙡𝙤𝙬-𝙝𝙮𝙙𝙧𝙤𝙜𝙚𝙣 𝙬𝙚𝙡𝙙𝙞𝙣𝙜 𝙚𝙡𝙚𝙘𝙩𝙧𝙤𝙙𝙚𝙨 (or filler materials) can help minimize the amount of diffusible hydrogen in the weld.
These electrodes are specifically designed to have low hydrogen content or include fluxes that can mitigate hydrogen pickup during welding.

► Applying 𝙋𝙒𝙃𝙏 after welding can relieve residual stresses and promote hydrogen diffusion, reducing the risk of delay cracking.

► Employing proper welding techniques, such as avoiding excessive heat input, controlling inter-pass temperature and maintaining appropriate welding parameters.

You're right, I should clarify which materials are most susceptible to delay cracking in general and why:

► 𝙃𝙞𝙜𝙝-𝙨𝙩𝙧𝙚𝙣𝙜𝙩𝙝 𝙨𝙩𝙚𝙚𝙡𝙨 - Most susceptible overall due to higher levels of residual stress and hardness.
Their higher carbon content and strength lead to hydrogen cracking.

► 𝙏𝙝𝙞𝙘𝙠 𝙨𝙚𝙘𝙩𝙞𝙤𝙣 𝙨𝙩𝙚𝙚𝙡𝙨 - The higher restraint in thicker plates increases residual stresses during cooling, making delay cracking more likely.

► 𝙍𝙚𝙨𝙩𝙧𝙖𝙞𝙣𝙚𝙙/𝙧𝙞𝙜𝙞𝙙 𝙟𝙤𝙞𝙣𝙩𝙨 - Any joint with high levels of restraint, like tubular joints or connections to heavy sections, are more prone to delay cracking due to residual stresses.

► 𝙃𝙞𝙜𝙝 𝙘𝙖𝙧𝙗𝙤𝙣 𝙨𝙩𝙚𝙚𝙡𝙨 - Carbon levels over 0.12% make steel more susceptible by increasing hardness, hydrogen absorption, and promoting carbide precipitation.

► 𝙁𝙚𝙧𝙧𝙞𝙩𝙞𝙘 𝙨𝙩𝙖𝙞𝙣𝙡𝙚𝙨𝙨 𝙨𝙩𝙚𝙚𝙡𝙨 - More susceptible than austenitic grades because they rely more on carbide stren
