American Petroleum Institute (API) is one of the largest organizations covering all aspects of the oil and gas industry. From upstream to downstream, API regulates standards and codes to help the petroleum industry grow while supervising its sustainability by adhering to environmental safety. In this article, PetroSync gives detailed information about API definition, the members of API, some of the well-known API standards and codes, as well as step-by-step to earn API certification.

What is API – American Petroleum Institute?

The American Petroleum Institute (API) is an association that represents the oil and gas industry in the United States.  API has arranged seminars, workshops, conferences, and symposia addressing public policy matters since it was established back in 1919 focusing on recommended practices regarding safety.

Further, API covers equipment, operations, effective water management, spill prevention, and environmental protection as part of its concern. Commonly used in federal and state oil and natural gas regulations, API standards have become one of the most cited standards by international regulators.

API has also established specific standards with the aim of promoting personnel and public safety in the oil and gas industry, including drilling, refinery operations, and well-servicing operations.

API lays the ground rules for companies and manufacturers to develop safety programs suitable for their operational needs. As a leading association with over 800 produced standards, API offers training and certification programs for workers in the industry.

Who Are The Members of The American Petroleum Institute (API)?

API members consist of producers, refiners, suppliers, pipeline operators, marine transportation companies, and service and supply companies that cater to all sectors of the oil and gas industry.

API has a vast membership base of over 600 corporate members, including some of the industry’s largest and most well-known brands. Some of the well-known members are from Petroleum companies such as ExxonMobil, Chevron, ConocoPhillips, BP America, and Shell Oil Company.

By connecting its members, API provides a forum to collaborate on common goals and advocate for policies that benefit the industry. If your company plans to join the community, you can check their official website.

What Are API Standards for the Oil Gas Industry?

American Petroleum Institute (API) standards promote established, reliable engineering, operational practices, and safe, interchangeable equipment and materials from drill bits to environmental protection. These encompass manuals, standards, specifications, recommended practices, bulletins, guidelines, and technical reports.

Companies can enhance their operational proficiency, guarantee compliance with regulations and safe procedures, and reduce the likelihood of equipment breakdowns leading to potential risks if they adhere to API codes and standards.

The standard provides guidelines for selecting the right refractory material for specific applications and ensuring it’s installed correctly. It also outlines procedures for inspecting the refractory lining to check for any defects or issues that could affect its performance. Following API 936 helps maintain the quality and safety of refractory linings in industrial equipment, such as furnaces and kilns, which are crucial for many manufacturing processes.

9. API 560 – Fired Heaters for General Refinery Service Online Training

API 560 is a standard that focuses on fired heaters used in refineries for heating various substances during the refining process. These heaters play a crucial role in heating crude oil and other materials to specific temperatures for processing.

The standard covers everything from the design and construction of these heaters to their operation and maintenance. It provides guidelines for ensuring that fired heaters are built safely and efficiently, meeting industry standards for performance and environmental protection.

API 560 outlines specifications for different types of fired heaters, including their components like burners, tubes, and refractory materials. It also includes requirements for safety systems and emissions control to minimize risks and environmental impact.

Following API 560 helps ensure that fired heaters in refineries operate reliably, efficiently, and safely, contributing to the smooth operation of refinery processes and compliance with regulatory standards.

What Is The Difference Between API Standard, API RP, and API MPMS?

1. API Standards (API STD)

API Standards are like rulebooks for the oil and gas industry. They provide detailed instructions on how to design, build, and operate equipment and systems used in the industry. These standards are essential because they ensure that everything, from storage tanks to wellhead equipment, meets specific technical requirements.

By following these standards, companies can maintain safety, quality, and consistency in their operations. For example, API STD 650 lays out the guidelines for constructing storage tanks, while API STD 6A defines the requirements for wellhead and Christmas tree equipment.

2. API Recommended Practices (API RP)

API Recommended Practices are helpful guides that provide advice on how to perform various tasks in the oil and gas industry. These practices are not mandatory but are considered industry best practices. They focus on specific areas and offer guidance on how to achieve desired outcomes safely and efficiently.

For instance, API RP 581 offers guidelines and a structured approach for assessing and managing the risk associated with the operation of equipment in the oil and gas industry. These recommended practices help companies make informed decisions and improve their processes.

3. API Manual of Petroleum Measurement Standards (API MPMS)

The API Manual of Petroleum Measurement Standards is a comprehensive resource that explains the detailed procedures and methods for accurately measuring and quantifying petroleum and petroleum-related products.

This manual is crucial for ensuring accurate measurements in the industry, as even small errors in measurement can have significant financial and operational consequences. By following the guidance in the API MPMS, companies can maintain precision and consistency in their measurement processes, which is essential for fair transactions and operational efficiency.

What is The Difference Between API Standard and ASME Standard?

API standards are designed mostly for the petroleum industry, addressing aspects like equipment design, fabrication, inspection, testing, and operational practices. Meanwhile, ASME standards have a broader application, extending to various engineering fields like mechanical, civil, chemical, and nuclear engineering.

Both API and ASME standards serve important roles in maintaining safe and reliable engineering practices, yet their scopes differ as API focuses on oil and gas, while ASME caters to multiple industries.

How To Get an Individual Certification Program (ICP) by API?
