Question 1

Which flange type is recommended for high pressure applications?

Accepted Answer

Weld neck flanges are recommended for high pressure and high temperature applications because their tapered hub provides excellent stress distribution and a strong welded joint.

Question 2

What are the most common flange types used in piping systems?

Accepted Answer

The most common flange types used in piping systems include slip on flanges, weld neck flanges, socket weld flanges, threaded flanges, lap joint flanges, and blind flanges. For proper selection, engineers often verify pipe dimensions using a pipe schedule chart and confirm load values with a pipe weight calculator available on www.sipeschedule.com.

Question 3

What is the difference between slip on flange and socket weld flange?

Accepted Answer

A slip on flange slides over the pipe and is welded from both sides, making it easy to install and cost-effective. A socket weld flange holds the pipe inside a recessed area and is typically used for small-diameter, high-pressure piping systems.

Question 4

Which standards are used for pipe flange dimensions and ratings?

Accepted Answer

Pipe flange dimensions and pressure ratings follow standards such as ASME B16.5, ASME B16.47, ANSI, DIN, and BS. These standards are commonly used alongside pipe schedule charts, NPT thread charts, and material weight calculators to ensure safe and accurate piping design.
