Industry insights, technical guides, and the latest news from Flanges.IO.
Everything you need to know about pipe flanges in one place. From weld necks to blinds, this guide covers every major flange type, how they work, and where they are used in industrial piping systems.
Choosing the right flange type can impact system performance, safety, and cost. We break down the key differences between weld neck and slip on flanges to help you make the right decision.
Pressure class ratings determine how much pressure a flange can withstand. Learn how to select the right class for your application, from Class 150 all the way to 20K.
Material selection is critical for flange performance and longevity. Compare carbon steel and stainless steel flanges across corrosion resistance, temperature range, cost, and application suitability.
The terms ANSI and ASME are often used interchangeably, but they refer to different organizations with distinct roles. This guide clarifies the relationship between ANSI and ASME standards and what it means for flange specifications.
Blind flanges are used to seal the end of a piping system, pressure vessel, or valve opening. Learn about blind flange dimensions, pressure ratings, materials, and the applications where they are essential.
Threaded flanges (also called screwed flanges) connect to pipes without welding. Discover when to use them, their pressure limitations, and why they are popular in low-pressure, non-critical applications.
Lap joint flanges offer unique advantages for systems that require frequent disassembly. Learn how they work with stub ends, their cost benefits, and the applications where they outperform other flange types.
Proper bolt torque is critical for leak-free flange joints. This guide covers recommended torque values by flange size and class, torquing sequence, and common mistakes to avoid during installation.
Why do piping engineers choose flanged connections over welded joints? From easy maintenance access to system flexibility, here are the top five benefits that make flanges essential to modern piping systems.
