Top 10 Questions to Ask When Buying Vacuum Insulated Tubing (VIT)

When purchasing vacuum insulated tubing (VIT) for oil, gas, or geothermal applications, it's crucial to ensure you're getting the right product for your specific needs. Below are the top 10 questions you should ask to make an informed decision:

1. What are the detailed specifications of the VIT?

• Ask about the available sizes, wall thickness, pressure ratings, and temperature tolerances.
• Ensure the VIT meets industry standards like API 5CT, ISO 9001, or others that are relevant to your application.

2. What is the insulation efficiency and heat loss rate?

• Request information on the thermal insulation performance, such as the U-value or heat loss rate, which is critical for energy efficiency in high-temperature environments.

3. What is the product's operational temperature range?

• Verify the VIT’s capacity to withstand the specific temperatures in your application, particularly if it involves extreme heat or cold.

4. What kind of testing and quality control measures are in place?

• Ask about the testing protocols for mechanical properties like pressure, temperature tolerance, and corrosion resistance.
• Ensure quality checks such as non-destructive testing (NDT) or hydrostatic pressure tests are performed.

5. What certifications does the product have?

• Inquire about certifications such as API 5CT, ISO 9001, ISO 14001, and others related to safety, quality, and environmental compliance.

6. How customizable is the product?

• Determine whether the manufacturer offers customization options, such as custom lengths, diameters, or insulation thickness, to suit your project needs.

7. What are the lead times and delivery capabilities?

• Confirm the production capacity and lead times to ensure the supplier can meet your project timelines without delays.
• Ask about shipping options and logistics support.

8. What are the warranty and after-sales support terms?

• Understand the warranty coverage and what after-sales support is available, such as technical assistance or replacement policies.

9. How does the product handle extreme environmental conditions?

• Inquire about the VIT’s performance in challenging environments like offshore, desert, or highly corrosive areas. Can the tubing withstand these conditions over time?

10. What is the product's lifespan and maintenance requirements?

• Ask for details on the expected lifespan of the VIT and any maintenance needed to ensure optimal performance and long-term reliability.
