When working with piping systems, understanding the relationship between Nominal Diameter (DN) and Outside Diameter (De) is crucial for accurate pipe selection, installation, and compatibility with fittings. This guide provides detailed insights into the DN and De relationship across different types of materials, including steel pipes and plastic pipes (PVC/PE/PPR). What is Nominal Diameter (DN)? […]

1. Introduction Pipeline purging is a common industrial operation that plays a critical role in ensuring system reliability and safety. It removes impurities such as welding slag, rust, and other debris from pipelines, preventing potential damage to downstream equipment. In applications such as syngas production and compressor systems, effective purging is essential for stable and

Introduction High-temperature steam and dense chemical liquids are at the core of coatings, adhesives, high-performance lubricants, and specialty fluids. For chemical plants, processing these high-viscosity materials means mastering intense heat and shear forces to ensure stable quality and consistent production. This article explores cutting-edge process technologies to overcome common issues such as pipeline clogging and

1. Common Pitfalls in Piping Installation Piping installation is often perceived as a routine task in industrial projects. However, even minor mistakes can lead to catastrophic system failures. Based on years of field experience, here are six common issues encountered during piping installation: 1.1 Poor Interpretation of Drawings and Improper Fit-Up In many projects, construction

In large-scale chemical, power, and petrochemical projects, piping and instrumentation may seem inconspicuous, but they are the “nerves” and “blood vessels” of the entire facility. When designed properly, systems operate reliably, require less maintenance, and deliver accurate data. When designed poorly, they become sources of error, constant alarms, frequent repairs, or even serious safety hazards.

Stainless steel, known for its excellent overall performance and aesthetic surface characteristics, is widely used in various industries—including in level instruments and fluid transport systems. Among its many forms, stainless steel pipes are the most commonly applied components. These pipes can be broadly categorized into two types: seamless stainless steel pipes and welded stainless steel

Introduction With the increasing number of pressure pipelines in various industries, safety management has become a critical concern. Many incidents related to pressure pipelines have been reported due to management loopholes, inadequate maintenance, and unforeseen failures. Therefore, understanding safety precautions, accident prevention strategies, and emergency response measures is crucial to ensuring pipeline integrity and minimizing

The primary purpose of insulating heating pipes and equipment is to minimize heat loss during the transfer process, conserve energy, and improve the economic efficiency and safety of the system. Insulation structures typically comprise multiple layers, including an anti-corrosion layer, an insulation layer, a moisture barrier (for cold insulation systems), a protective layer, and identification

Pipeline stress refers to the various forces and pressures that a pipeline experiences due to internal or external factors. It is a critical consideration in the design, construction, and operation of pipelines, directly impacting their safety, reliability, and longevity. Understanding and managing pipeline stress is essential for minimizing risks and ensuring system stability. This article

Pipeline design is a critical engineering task that ensures the efficient, safe, reliable, and economical transportation of fluids. It integrates principles from mechanical, hydraulic, and structural engineering, making it a multidisciplinary challenge. Industries such as chemical processing, oil and gas, power generation, and water treatment rely heavily on well-designed pipeline systems to maximize production efficiency,
