1. Introduction to Corrosion Protection Grades Corrosion protection grades define the surface treatment capabilities of materials and structures to resist environmental corrosion. Corrosion refers to the deterioration of materials (primarily metals) due to chemical or electrochemical reactions with their surroundings, leading to compromised performance. In industrial and architectural applications, selecting the appropriate corrosion protection grade […]

In environments with explosion risks, such as chemical plants, maintaining explosion-proof electrical equipment is critical to ensuring operational safety and protecting the health of employees. These devices must not only withstand harsh conditions but also maintain their explosion-proof characteristics. Below is a comprehensive guide to maintaining explosion-proof electrical equipment, focusing on key points to ensure

To ensure the optimal operation and measurement accuracy of double-flange liquid level transmitters, special attention must be paid to the selection, installation, and maintenance of capillary tubes. Below are the detailed guidelines: 1. Selection of Capillary Tube and Filling Liquid Choose the Appropriate Filling Liquid: Select the filling liquid based on the temperature requirements of

In chemical plants, control rooms—including central control rooms, on-site control rooms, and equipment cabinet rooms—serve as the nerve centers of operations. These spaces house a variety of high-precision electronic devices, such as computers, servers, and communication equipment, which are essential for monitoring and controlling production processes. Given the sensitivity of these devices, the implementation of

In instrumentation field installations, the excessive length of cables beyond the actual required usage can lead to multiple issues. This article explores the four primary risks: economic impact, signal transmission accuracy, construction efficiency, and operational maintenance. 1. Economic Impact Excessive cable length directly contributes to increased procurement costs. With the current rise in non-ferrous metal

Introduction Diaphragm gas meters, also known as membrane gas meters, are widely used instruments for measuring gas flow. With the acceleration of urbanization and the widespread adoption of gas supply systems, accurate gas measurement has become crucial for both residential and commercial users. Diaphragm gas meters are favored for their simple structure, affordability, high accuracy,

1. The Necessity of Insulating Double-Flange Capillary Tubes Whether double-flange capillary tubes require insulation depends on the specific application environment and conditions. Below are the key scenarios: 1.1 Generally, Insulation is Not Required Under normal operating conditions, the filling liquid inside double-flange capillary tubes (e.g., silicone oil) is designed to adapt to environmental temperature changes
