Flange

In industrial piping systems, flanges play a vital role in connecting pipelines, valves, pumps, and other equipment. They ensure sealing, mechanical strength, and serviceability. However, many engineers and technicians tend to overlook a crucial aspect: the markings etched onto the flange surface. These seemingly minor letters and numbers provide essential information that can determine whether […]

1. Introduction In the fields of industrial automation and fluid control, process connections are critical for ensuring secure installation, excellent sealing performance, and safe operation of equipment. The Japanese Industrial Standards (JIS) system provides a unique approach to flange connections, differing from ANSI and DIN standards commonly used internationally. JIS flanges are widely adopted in

Introduction In industrial piping systems, ensuring electrical continuity and safety is critical—especially in environments where flammable or explosive media are present. One frequently asked question is whether flanges connected by five bolts (or any bolted flange connection) still require bonding straps or jumpers. This article explores the technical rationale and applicable standards behind bonding requirements

Introduction Flanges are crucial components in piping systems, providing secure connections between pipes, valves, pumps, and other equipment. To ensure proper identification and compliance with industry standards, manufacturers mark flanges with specific details. These markings provide critical information about the flange’s specifications, including material, pressure rating, dimensions, and manufacturing details. This guide will explore the

Static electricity bonding for flange bolts is an essential safety measure, especially in industrial piping systems that transport flammable or explosive materials. Proper bonding ensures that any potential static charge accumulation is safely dissipated, preventing the risk of sparks that could lead to hazardous incidents. This article provides a comprehensive guide on how to perform

Flanges are essential components used to connect pipes, valves, pumps, and other equipment in piping systems. They come in various types and designs to suit different applications, pressure levels, and operational conditions. This article provides a detailed overview of the most common flange types, their designations, and their typical applications. 1. Plate Flange (PL) Description:

In the construction and maintenance of pipe systems, selecting the appropriate connection method is critical. Different connection methods offer unique features, advantages, and limitations, making them suitable for specific applications. Common pipe connection methods include clamp, flange, and threaded connections. This article provides a detailed comparison of these methods, discussing their principles, benefits, drawbacks, and

Introduction Flanges are crucial components in industrial piping systems, serving as essential connectors and seals. The markings on flanges provide vital information regarding their specifications, materials, design standards, and manufacturing or testing requirements. Understanding these markings is critical for ensuring proper installation, maintenance, and operational efficiency. 1. Components of Flange Markings Flange markings are typically

Flanges are essential components used to connect pipes, valves, pumps, and other equipment in a piping system. Two common types are slip-on flanges (commonly referred to as SO flanges) and weld-neck flanges (WN flanges). They differ significantly in terms of structure, welding methods, mechanical properties, and applications. This article provides a detailed analysis of these

Proper selection of bolts for flange connections is critical to ensuring safety and reliability in mechanical systems. This article explains the detailed steps to determine the appropriate bolt quantity, diameter, and length when designing or installing flange connections. 1. Understanding the Flange Standard Flanges are manufactured according to various international standards, such as: ASME/ANSI B16.5
