From Vessel Rupture to Weld Failure and Flange Leakage In real engineering practice, ASME is rarely discussed in philosophical terms.Most engineers encounter it in a much more concrete — and often frustrating — way: Required wall thickness suddenly increases Additional radiographic testing is requested Flange ratings must be reselected Documents are rejected and returned for […]

A Common Engineering Misunderstanding in Atmospheric and Low-Pressure Storage Tanks In the petroleum, chemical, energy, and pharmaceutical industries, atmospheric and low-pressure storage tanks are among the most widely used process equipment.Unlike pressure vessels, the safety of these tanks does not rely on shell strength, but instead depends heavily on the effectiveness of their venting systems.

Pipe expansion joints are essential components in piping systems, designed to absorb thermal expansion, contraction, and other mechanical movements. A common question arises when dealing with the external screws (often called transportation bolts or limit rods) on these joints: should they be removed, or should the nuts be tightened during installation and operation? The answer

In industrial plants, energy metering systems, and water or wastewater applications, inaccurate flow readings are a common complaint.Very often, the first assumption is that the flow meter itself is faulty or poorly selected. However, real field experience shows a different truth: In most cases, inaccurate flow measurement is caused by improper installation and unfavorable process

In industrial manufacturing, fasteners are often categorized as standard or general-purpose components. Common fasteners include bolts, nuts, screws, washers, pins, and rivets, and they seem simple enough to procure based on specifications and install according to design. However, in modern industrial engineering systems, fasteners are far more than mere connecting parts. They are subject to
