Product Description

Product Description

The description "Heat Exchanger Stainless Steel Coil Tubing 316L 321 304 stainless steel coil pipe for oil and gas" suggests a highly specialized use of stainless steel tubing designed for heat exchangers in the oil and gas industry. Each component of the description indicates specific material grades and applications. Here's a deeper look:

Material Grades Explained:

1. 316L Stainless Steel:

   • Contains 16-18% chromium, 10-14% nickel, and 2-3% molybdenum, along with a low carbon content. The addition of molybdenum improves its resistance to corrosion in chloride environments and enhances overall corrosion resistance.
   • 316L is well-suited for harsh environments, particularly in marine conditions and acidic environments, which makes it ideal for oil and gas applications where corrosion from seawater and harsh chemicals is a concern.

2. 321 Stainless Steel:

   • Includes about 17-19% chromium and 9-12% nickel with titanium addition at least five times the carbon content. This composition prevents chromium carbide formation by stabilizing against chromium depletion.
   • 321 is particularly useful in applications where high temperatures are common, as it resists oxidation and intergranular corrosion even at temperatures up to 900°C.

3. 304 Stainless Steel:

   • Known for its excellent corrosion resistance and value, 304 contains 18% chromium and 8% nickel. It is the most common form of stainless steel used around the world, suitable for a wide range of atmospheric environments and many corrosive media.
   • Although less resilient in chloride environments than 316L, it provides substantial durability and resistance to a broad range of chemicals and temperatures.

Coil Tubing:

• Stainless Steel Coil Tubing: This refers to stainless steel that has been formed into long, coiled rolls. Coil tubing is used in applications requiring a high level of resistance to corrosion and heat. Stainless steel coil tubing ensures fewer connections and joints, enhancing the integrity and fluid flow characteristics.

Applications in Oil and Gas:

• Heat Exchangers: Utilized extensively in heat exchangers, which require tubing that can withstand aggressive chemicals and high temperatures while maintaining effective heat transfer properties.
• Oil and Gas Production: Used for downhole, subsea, onshore, and offshore oil and gas production where high resistance to corrosion and heat is crucial.
• Chemical Injection Lines: Stainless steel coil tubing is often used for chemical injection lines in the oil and gas sector due to its corrosion resistance, which ensures the safe and effective delivery of chemicals at high pressures.

General Utility:

• Durability: These stainless steel grades are chosen for their long-lasting nature and resistance to harsh environmental conditions.
• Efficiency: The seamless nature of coil tubing contributes to greater efficiency in heat transfer applications and reduced risk of leaks.

The combination of 316L, 321, and 304 stainless steels in coil form makes this product exceptionally suitable for critical and high-performance applications across the oil and gas industry, where both environmental resistance and high thermal performance are necessary.
