What does NACE mean? What is the NACE standard? And its application in the steel pipe industry

DataTime:[2024-7-1]

The direct economic losses caused by metal corrosion worldwide each year are approximately 700 billion to 1 trillion US dollars. Among them, the annual corrosion losses in the United States amount to over 300 billion US dollars, accounting for 4.2% of GDP. China's corrosion losses in 2014 were approximately 2 trillion yuan, accounting for 3% of its GDP that year. The harm of corrosion is self-evident, and besides economic losses, the damage to society and life safety cannot be estimated.

1. What does NACE mean?

Global Corrosion Protection Authority - NACE

NACE International was founded in 1943 by 11 corrosion engineers from the pipeline industry, initially known as the American Society of Corrosion Engineers. After decades of development, today NACE has over 37000 members in 140 countries and regions worldwide, and is recognized as a professional authority in the field of corrosion control worldwide.

NACE International provides technical training, certification programs, industry standards, technical reports, books, publications, government relations, and other activities and services. NACE originated in the field of petroleum and petrochemical, and then covered all major industries. It has developed rapidly in the world through the offshore shipbuilding industry.

In the past few decades of development, NACE has become a global leader in the development of corrosion protection and control regulations, certification, and education. Now, it is widely recognized globally as an authority in providing corrosion control solutions.

What is the NACE standard?

The NACE standard is a non mandatory guideline set by the Technical Committee for the field of corrosion prevention and control. NACE provides corrosion assessment for underground pipelines and material certification for related products. NACE also provides professional qualification certification for technical personnel, such as certification for coating professional service engineers.

The standard "NACE MR0175 Petroleum and Natural Gas Industry - Materials for Use in H2S containing Environments in Oil and Gas Production", jointly released by the American Society of Corrosion Engineers (NACE) in 2001, is a standard specifically designed for corrosion issues in H2S containing oil and gas field development.

2. Introduction to the NACE standard

NACE (National Association of Corrosion Engineers) is an internationally renowned association of corrosion engineers dedicated to researching corrosion and its control technologies. In the field of steel pipes, the NACE standard is widely used to evaluate and manage the corrosion resistance performance of steel pipes. The implementation of the NACE standard is of great significance for protecting steel pipes from corrosion and erosion.

3. The Impact of NACE Standards

1. Improve the corrosion resistance of steel pipes

The NACE standard requires steel pipes to have good corrosion resistance in specific environments to ensure their long-term use under harsh conditions. Through reasonable design and material selection, steel pipe manufacturers can produce high corrosion resistance steel pipes that comply with the NACE standard, improving their service life.

2. Ensure the safe operation of industrial equipment

Many industrial equipment, such as oil and gas pipelines, chemical plants, etc., require the use of steel pipes with excellent corrosion resistance. Steel pipes that comply with the NACE standard can effectively prevent safety hazards caused by corrosion and ensure the safe operation of industrial equipment.

3. Reduce maintenance costs

Steel pipes are prone to corrosion and erosion in harsh environments, while steel pipes that comply with the NACE standard can effectively resist corrosion, reduce maintenance frequency and costs. This has important economic significance for industries that use a large amount of steel pipes, such as petroleum and chemical industries.

4. Promote innovation and development of steel pipe technology

The NACE standard imposes strict requirements on the corrosion resistance of steel pipes, which encourages steel pipe manufacturers to innovate and develop better steel pipe materials and processes. This not only improves the performance of steel pipes, but also drives the development of the entire steel pipe industry.

3. Selection of Steel Pipe Materials in Accordance with NACE Standards

1. Stainless steel pipe

Stainless steel pipe is a commonly used steel pipe material that complies with the NACE standard, and it has good corrosion resistance and mechanical properties. In corrosive environments, stainless steel pipes can effectively prevent corrosion and also resist the effects of high temperature and high pressure, making them suitable for various industrial fields.

2. Corrosion resistant alloy steel pipes

Corrosion resistant alloy steel pipe is another common steel pipe material that complies with the NACE standard. It improves the corrosion resistance of the steel pipe through alloy addition. Corrosion resistant alloy steel pipes have good acid and alkali resistance, high temperature resistance, and mechanical properties, and are widely used in industries such as chemical and petroleum.

3. Plastic coated steel pipes

Plastic coated steel pipe is a type of steel pipe coated with anti-corrosion plastic on the outer layer, which can effectively isolate the contact between the steel pipe and the environment, and play a role in corrosion prevention. Plastic coated steel pipes have excellent corrosion resistance in some special corrosive environments, such as marine environments and underground pipelines.

4. Summary

The application of the NACE standard in the steel pipe industry is of great significance for protecting steel pipes from corrosion and erosion. Steel pipes that comply with the NACE standard can improve corrosion resistance, ensure the safe operation of industrial equipment, reduce maintenance costs, and promote innovation and development of steel pipe technology. Stainless steel pipes, corrosion-resistant alloy pipes, and plastic coated steel pipes are common steel pipe materials that comply with the NACE standard. With the continuous advancement of technology, we believe that the application of the NACE standard in the steel pipe industry will be further expanded and improved, providing us with more high-quality steel pipe products.
