ANSI/ASME B16.5 and B16.47 standards define standardized pressure–temperature limits for flanged piping systems. Each pressure class corresponds to a specific rating that varies based on material group and operating temperature. This article explains these ratings, ranging from Class 150 through
ANSI/ASME flanges are the primary connection components which are used in industrial piping systems across oil & gas, petrochemical, power generation, water treatment, and mechanical/HVAC applications.ANSI/ASME B16.5 covers NPS ½” to 24” in pressure classes 150 to 2500. Flange types
ANSI/ASME flanges are built specifically for high-pressure piping systems, as they can maintain a reliable seal under demanding conditions. They work by compressing a gasket between two machined flange faces using bolts. This creates a controlled, leak-proof seal that is
Slip on and weld neck flanges represent two distinct approaches in piping connections, each with specific advantages and trade offs. This guide reviews the pros and cons of slip on and weld neck flanges, explaining how they differ and when
The American National Standard Institute (ANSI) Sectional Committee B16 has been defining publishing safety and dimensional standards for piping systems since 1922. Sectional Committee B16 was reorganized as an ASME (American Society of Mechanical Engineers) standards committee in 1982 with
Slip on flanges and blind flanges, two of the most common options, serve very different roles within the same piping system. Slip-on flanges provide cost effective connection points for pipes and equipment, while blind flanges ensure a secure closure at
ASME/ANSI flanges are standardized components used to connect pipes, valves, pumps, pressure vessels, and other equipment in industrial piping systems. The modern standards governing these flanges are published by the American Society of Mechanical Engineers (ASME). People often call these
In piping projects, slip-on flanges offer several key benefits: lower cost, easier installation, standardized pressure ratings, and the ability to handle large-diameter lines with minimal preparation. They are recognized in standards such as ASME & AWWA, and are available in
Slip-on flanges are a practical choice across many industrial settings, valued for their cost-effectiveness, ease of installation, and reliable performance under moderate conditions. Even though they are not designed for the highest pressure or most demanding service lines, they still
In this introduction to flanges, we’ll cover what flanges are, how they’re made, and the different ways they connect piping systems. The article also provides an overview of pressure and temperature ratings, material options, and industry standards that guide proper
