2507 Stainless Steel Coil for Oil & Gas Pipelines: 316LMOD/316Ti - Superior Corrosion and Fatigue Resistance

1. Product Overview

Our 2507 stainless steel coil, featuring 316LMOD/316Ti, is specifically engineered for the demanding oil and gas pipeline industry. This coil represents a pinnacle of modern metallurgy, offering outstanding performance in harsh environments where corrosion and fatigue are constant threats. The 2507 grade is a super duplex stainless steel that combines the benefits of austenitic and ferritic stainless steels, resulting in a material with high strength, excellent corrosion resistance, and remarkable fatigue endurance.

2. Surface Treatment and Technique

• Surface Treatment: Polished
  • The polished surface of our 2507 stainless steel coil not only enhances its aesthetic appeal but also provides practical benefits. A polished finish reduces surface roughness, minimizing the adhesion of contaminants and corrosive substances. This smooth surface is easier to clean, which is crucial in oil and gas applications where the presence of dirt, oil, and other impurities can accelerate corrosion.
• Technique: Hot Rolled
  • The hot - rolled manufacturing process is employed to produce our stainless steel coils. Hot rolling involves heating the steel to high temperatures and then passing it through rollers to achieve the desired thickness and shape. This process imparts several advantages. Firstly, it refines the grain structure of the steel, improving its mechanical properties such as strength and toughness. Secondly, hot - rolled coils have better formability, allowing for easier fabrication into various pipeline components.

3. Standards and Compliance

• Standard: ASTM
  • Our 2507 stainless steel coil adheres to the American Society for Testing and Materials (ASTM) standards. ASTM standards are widely recognized and respected in the international market, ensuring that our product meets the highest quality and performance requirements. Compliance with ASTM standards guarantees that the coil has consistent chemical composition, mechanical properties, and dimensional accuracy. This is essential for oil and gas pipeline applications, where strict quality control is necessary to ensure the safety and reliability of the infrastructure.

4. Key Features: Corrosion and Fatigue Resistance

• Corrosion Resistance
  • In the oil and gas industry, pipelines are constantly exposed to corrosive substances such as saltwater, hydrogen sulfide, and carbon dioxide. Our 2507 stainless steel coil offers exceptional corrosion resistance due to its high chromium, molybdenum, and nitrogen content. Chromium forms a passive oxide layer on the surface of the steel, which acts as a barrier against corrosion. Molybdenum further enhances the resistance to pitting and crevice corrosion, which are common forms of corrosion in oil and gas environments. Nitrogen improves the overall corrosion resistance and also increases the strength of the steel.
• Fatigue Resistance
  • Pipelines in the oil and gas sector are subject to cyclic loading, such as pressure fluctuations and vibrations. Fatigue failure can occur when a material is repeatedly stressed below its ultimate strength. The 2507 stainless steel coil has excellent fatigue resistance, thanks to its unique microstructure and high strength - to - weight ratio. The duplex structure of the steel provides a better balance between strength and ductility, allowing it to withstand repeated loading without cracking or failing prematurely.

5. Applications in Oil and Gas Pipelines

• Onshore and Offshore Pipelines
  • Our 2507 stainless steel coil is suitable for both onshore and offshore oil and gas pipelines. Onshore pipelines may be exposed to soil corrosion, moisture, and chemical contaminants, while offshore pipelines face the additional challenges of saltwater corrosion and high - pressure environments. The corrosion and fatigue resistance of our coil make it an ideal choice for these applications, ensuring long - term reliability and reduced maintenance costs.
• Subsea Pipelines
  • Subsea pipelines are subjected to extreme conditions, including high hydrostatic pressure, low temperatures, and aggressive seawater. The high strength and corrosion resistance of our 2507 stainless steel coil enable it to withstand these harsh conditions. It can be used for the transportation of oil, gas, and other fluids in subsea environments, providing a durable and safe solution for the oil and gas industry.
