The main reasons why stainless steel strips are widely used in the petroleum processing industry are as follows:
1. Good corrosion resistance
Chemical corrosion resistance: During the process of oil extraction and processing, it comes into contact with various corrosive substances, such as oil and gas containing hydrogen sulfide, carbon dioxide, chloride, as well as chemical agents such as acid and alkali liquids. The alloying elements such as chromium and molybdenum in stainless steel strips can form a dense passivation film on their surface, effectively preventing these corrosive substances from reacting chemically with the metal substrate, preventing the steel strip from being corroded, and extending the service life of equipment and pipelines.
Corrosion resistance to seawater: In offshore oil extraction, equipment and pipelines inevitably come into contact with seawater, and the high salinity and complex composition of seawater require high corrosion resistance of materials. Stainless steel strip has good resistance to seawater corrosion, which can resist the erosion of seawater and ensure the safe and stable operation of offshore oil facilities.
2. High strength and good toughness
Enduring high pressure: Many aspects of the petroleum processing industry, such as oil well extraction and pipeline transportation, are subjected to high pressure environments. Stainless steel strip has high strength, can withstand these high pressures, is not prone to deformation, cracking and other problems, ensuring the safety of oil production and transportation processes.
Resistance to impact: During the operation of petroleum equipment, it may be subjected to external forces such as fluid impact and mechanical vibration. The good toughness of stainless steel strip enables it to absorb and buffer these external forces, avoiding equipment damage or leakage accidents caused by brittle fracture.
3. High temperature resistance performance
Adaptation to high temperature environment: Distillation, cracking and other processes in petroleum refining need to be carried out under high temperature conditions. Stainless steel strips can maintain stable physical and chemical properties in high temperature environments, and are not easily softened, deformed or oxidized, ensuring the normal operation of related equipment and components.
Ensure system stability: In high-temperature oil transportation pipelines, stainless steel strips can maintain their structural strength and sealing performance, prevent pipeline leaks or system failures caused by temperature changes, and ensure the stability and reliability of the oil transportation system.
4. Good processability
Easy to form: Stainless steel strips can be processed through various methods such as bending, stamping, welding, etc. to produce various shapes and sizes of components and equipment, such as pipes, elbows, flanges, screening baskets, etc., to meet the application needs of different scenarios in the petroleum processing industry.
Easy to install and maintain: Good processability makes equipment and components made of stainless steel strips more convenient and efficient during installation, which can improve construction efficiency. At the same time, it is also easy to perform cutting, welding, and other operations during equipment maintenance and repair, reducing maintenance costs and difficulty.
5. Good cleanliness and hygiene
Ensure oil quality: The surface of stainless steel strip is smooth, not easy to adsorb impurities and oil stains, which can maintain the cleanliness of petroleum products, avoid pollution to oil products during storage and transportation, and ensure the quality of petroleum products.
Compliance with hygiene standards: In some special fields related to petroleum, such as food grade lubricant production, biodiesel production, etc., there are strict requirements for the hygiene of materials. The non-toxic and non bacterial characteristics of stainless steel strips make them comply with relevant hygiene standards and meet the needs of these special applications.
