Inconel 718, or Inconel alloy 718, is a strong nickel-based superalloy. Engineers design it to handle extreme temperatures, high pressure, and harsh environments. This article gives an overview of the types of Inconel 718 tubes and tubing we offer. It covers their specifications, quality control measures, and our fast delivery processes.

1. Product Types Offered by Our Company

We offer different types of Inconel 718 pipes and tubing. This ensures our clients get the right product for their needs. Our product offerings include:

1.1 Seamless Inconel 718 Pipes and Tubes

Description: 718 seamless tubes are perfect for high-pressure and high-temperature uses. People frequently use these tubes in aerospace, nuclear power, and chemical industries, where reliability and performance are crucial.
Common Sizes: Outer diameter (OD) ranges from 6 mm to 500 mm, with wall thickness from 0.5 mm to 60 mm.
Standards: ASTM B163, ASTM B730, ASME SB163.
Additional Information: Customized dimensions and specifications request acceptable.

1.2 Welded Inconel 718 Pipes and Tubes

Description: Welded tubes offer a cost-effective alternative to seamless tubes. Welders join metal strips together. People often use these items where strength and pressure are less critical. However, they still need to resist high temperatures and corrosion.
Common Sizes: Outer diameter (OD) ranges from 6 mm to 500 mm, with wall thickness from 1 mm to 20 mm.
Standards: ASTM A312, ASTM A358, ASTM B674.
As a typical application，we offer nickel alloy heat exchanger welded tubes. These tubes are great for corrosive environments. They are also good for applications needing better heat resistance.

1.3 Round Inconel 718 Pipes and Tubes

Description: Round tubes are one of the most versatile shapes for structural components and fluid transport. We offer both seamless and welded options. This ensures we can meet the needs of industries like aerospace, automotive, and power generation.
Common Sizes: The outer diameter (OD) ranges from 1/8 inch (3.175 mm) to 24 inches (609.6 mm). The wall thickness varies from 0.5 mm to 30 mm.
Standards: ASTM B515, ASTM B730.

1.4 Square Inconel 718 Tubes

Description: Square tubes provide greater strength and rigidity, often used in construction and framework applications. Although manufacturing is more complex compared to round tubes, square tubes offer superior structural support and durability.
Common Sizes: Outer dimensions range from 10 mm × 10 mm to 200 mm × 200 mm, with wall thickness from 1 mm to 10 mm.
Standards: ASTM A554, ASTM B730.

1.5 Capillary Inconel 718 Tubes

Description: Capillary tubes have small diameters and are used in precision applications, such as laboratory instruments, medical devices, and microfluidic systems. We offer these in both seamless and welded forms, depending on your project needs.
Common Sizes: Outer diameter (OD) ranges from 0.3 mm to 6 mm, with wall thickness from 0.1 mm to 2 mm.
Standards: ASTM B517, ASTM B730.

2. Specifications and Standards of Inconel 718 Pipes and Tubes

We make our Inconel 718 tubes and tubing to meet international standards. This ensures they have the best quality and performance. Here are the key specifications for the products we offer:

Seamless Tubes: ASTM B163, ASTM B730, ASME SB163. Outer diameter (OD) ranging from 6 mm to 500 mm and wall thickness up to 60 mm.
Welded Tubes: ASTM A312, ASTM A358, ASTM B674. Sizes ranging from 6 mm to 500 mm in OD, with wall thickness from 1 mm to 20 mm.
Round Tubes: ASTM B515, ASTM B730. Outer diameter ranging from 1/8 inch to 24 inches, with wall thickness from 0.5 mm to 30 mm.
Square Tubes: ASTM A554, ASTM B730. Outer dimensions ranging from 10 mm × 10 mm to 200 mm × 200 mm, with wall thickness from 1 mm to 10 mm.
Capillary Tubes: ASTM B517, ASTM B730. Available in outer diameters from 0.3 mm to 6 mm, with wall thickness from 0.1 mm to 2 mm.

We also offer Werkstoff nr 2.4668, the European designation for the Inconel 718 alloy. This ensures our products meet both international and local standards.

3. Quality Control

We follow strict quality control processes. This ensures that every piece of Inconel 718 tubing meets high standards. Our quality assurance includes:

Material Inspection: We test each batch of Inconel 718 alloy for its chemical composition. This ensures it meets ASTM and international standards.
Dimensional Inspection: We utilize advanced measurement technologies to guarantee that all dimensions are within the specified tolerances.
Non-Destructive Testing (NDT): We use ultrasonic testing, eddy current testing, and other methods. These help us find surface and internal defects.
Mechanical Testing: We conduct tensile strength, hardness, and impact tests. These tests confirm the alloy’s mechanical properties. This ensures the alloy performs well in tough environments.

4. Delivery and Lead Time

As a trusted Inconel 718 tubing supplier, we maintain a large inventory to ensure quick turnaround times. Typical lead times for custom sizes and special orders range from 2 to 6 weeks, depending on complexity. We offer various shipping options to ensure timely delivery to meet project deadlines.
