How to Choose the Right Incoloy 800 Tubing for Your Application

How to Choose the Right Incoloy 800 Tubing for Your Application?

One of the critical elements in the success of industrial processes is selecting the right materials. The same applies when choosing incoloy 800 tubing, widely used in various applications where heat resistance, corrosion resistance, and strength are critical requirements. While the incoloy 800 tube has a broad range of applications, choosing the right grade and size can be daunting. This article provides a comprehensive guide on choosing the right incoloy 800 tubing for your application.

What is Incoloy 800 Tubing?

Incoloy 800 tubing is a high-temperature, corrosion-resistant alloy used for piping and tubing in industrial settings. It features exceptional strength and flexibility at temperatures up to around 1150°C (2100°F), along with great heat and oxidation resistance. This makes it ideal for superheater tubes, headers, steam lines, manifolds, and instrumentation lines.

Advantages of Using Incoloy 800 Tubings

Chemical Composition

Incoloy 800 tubing is an alloy that contains nickel, chromium, and iron. This composition gives the tubing several advantages over other types of tubing. For example, the nickel content makes the tubing resistant to corrosion, while the chromium content gives it resistance to high temperatures.

Physical Properties

In addition to its chemical composition, Incoloy 800 tubing also has several advantageous physical properties. For example, the tubing is non-magnetic, meaning it can be used in applications where magnetic materials are unsuitable. Additionally, the tubing has a high melting point, meaning that it can be used in high-temperature applications.


In addition to its other advantages, Incoloy 800 tubing is also cost-effective. This is because the tubing can be easily formed and welded, requiring less material to produce a given product. The tubing has a long lifespan, meaning it will not need to be replaced as often as other types.


Incoloy 800 tubing is also versatile and can be used in various applications. For example, the tubing is commonly used in heat exchangers, condensers, and boiler tubes. Additionally, the tubing can be used in chemical processing equipment and nuclear reactors.

Available in a Variety of Sizes

Incoloy 800 tubing is available in various sizes to meet the needs of different applications. The most common sizes are 1/2 inch (12 mm), 3/4 inch (19 mm), 1 inch (25 mm), and 1 1/2 inches (38 mm).

Choosing the Ideal Incoloy 800 Tubing for Your Application

Consider Your Application Requirements

Consider your application requirements carefully before settling on any incoloy 800h tubing material. In other words, how much heat exposure will the tubing be exposed to? Will it be subjected to high pressure or corrosive chemicals? An in-depth analysis of the application will determine the tubing grade you need. For instance, Incoloy 800H tubing is recommended for reducing environments, while Incoloy 800HT is suitable for high-temperature applications with superior mechanical properties.

Evaluate Tubing Dimensions

Incoloy 800 tubing comes in various sizes and thicknesses to suit different applications. Selecting the tubing dimensions requires considering the required flow rate, pressure, and temperature. Choosing the wrong dimensions could result in inefficiencies, increased energy costs, or even damage to the tubing due to high pressure.

Check Material Quality

A key consideration is the quality of the tubing material. You should ensure that the supplier provides high-quality Incoloy Alloy 800 tubing that meets international standards. Such tubing is produced under strict conditions and goes through quality testing to ensure strength, durability, and corrosion resistance. Investing in high-quality tubing may be more expensive, but it will save you money in the long run since you will not have to replace it regularly.

Verify Supplier Credentials

Your supplier of Incoloy 800 tube also plays a critical role in ensuring that the tubing you receive meets your expectations. Before choosing a supplier, conduct thorough research to verify the supplier’s credentials, experience, and reputation. A reputable supplier should have years of experience supplying high-quality tubing to various industries. Furthermore, their tubing should meet industry standards such as ASME, ASTM, and ANSI.

Consider Production Lead Times

Lastly, considering the production lead times could go a long way in ensuring a smooth production process. Before making an order, enquire about the supplier’s lead times and if they can deliver the tubing within your production schedule. Some suppliers may have strict lead times, while others are flexible. Choosing a supplier with shorter lead times could minimize production downtime.


Choosing the right incoloy 800 tubing is crucial for the success of your industrial process. You can make an informed decision when you consider your application requirements, tubing dimensions, material quality, supplier credentials, and production lead times. Remember, selecting the wrong tubing material can lead to inefficiencies, increased energy costs, and even damage to the equipment. That said, partnering with a reputable incoloy tubing supplier can ensure you get the right tubing for your application at a fair cost and within set deadlines.
