2. Types of Inconel 625 Pipes and Tubing

As a trusted supplier, we provide Inconel 625 pipe and 625 tubing. Each product serves specific uses that require high performance in tough conditions.

2.1 Pipes (Inconel 625 Pipe):

  • People often use Inconel 625 pipe in places with high temperatures and high pressure. People also use it in corrosive environments. Common applications include chemical processing plants, offshore platforms, and power plants.
  • Features: Inconel 625 pipe is strong and resists corrosion. It performs well at high temperatures. This makes it great for exhaust systems and gas turbines.

2.2 Tubing (Inconel 625 Tubing):

  • Applications: Manufacturers use Inconel 625 tubing in tough, hot environments. You can find it in fluid transport systems, heat exchangers, and aerospace parts.
  • Features: 625 tubing possesses slimmer walls compared to pipes. Engineers design it for strength. It resists oxidation, fatigue, and thermal expansion.

2.3 Seamless vs. Welded Pipes:

  • Seamless pipes: These pipes offer superior durability and strength, especially in high-pressure applications.
  • Welded pipes are a cost-effective choice for low-pressure situations. Welded Inconel 625 pipes keep their strong resistance to corrosion and high temperatures.

4. Surface Treatment of Inconel 625 Pipes and Tubing

At Southerly Alloy Co., Ltd, we know how important surface treatments are. They improve the durability and performance of Inconel 625 pipe and 625 tubing. We offer several surface treatment options to meet your needs:

  • Pickling and Passivation: This process removes surface oxides and contaminants, improving corrosion resistance.
  • Electropolishing: For applications requiring smooth and reflective surfaces, electropolishing is available to reduce surface roughness and improve wear resistance.
  • Shot Peening: This process improves fatigue resistance. It helps make Inconel 625 tubing perform better in high-stress situations.
  • Coating: We can also apply various coatings to enhance surface protection in particularly aggressive environments.

5. Chemical Composition and Performance

The exceptional properties of Inconel 625 are largely because of its unique chemical composition. Below is a detailed breakdown of the alloy’s chemical components:

ElementComposition Range (%)
Nickel (Ni)58 - 70
Chromium (Cr)20 - 23
Molybdenum (Mo)8 - 10
Iron (Fe)Balance
Niobium (Nb)3.15 - 4.15
Titanium (Ti)0.4 - 1
Aluminum (Al)≤ 0.4
Copper (Cu)≤ 0.5
Manganese (Mn)≤ 1
Silicon (Si)≤ 0.5

This composition gives Inconel 625 its distinctive features, such as:
