A Manufacturing Execution System (MES) is a crucial production management system designed for manufacturing enterprises. It connects the enterprise’s planning layer (ERP) with the on-site control layer (PLC, SCADA, etc.), enabling real-time monitoring of production processes, data collection, quality management, and process execution. The main goal is to improve production efficiency, product quality, and responsiveness. […]

In chemical production, startups and shutdowns are routine but critical operations. Short-term shutdowns generally have minimal impact on instruments, with limited adjustments needed by instrumentation personnel. However, this document focuses on large-scale shutdowns and startups, such as those due to major overhauls, extensive stoppages, or events requiring prolonged halts and subsequent restarts of operations. Note

Introduction Japanese Industrial Standards (JIS) define various thread types for different industrial applications. These threads are widely used in mechanical components, piping systems, and precision instruments. This article provides an overview of the most common JIS thread types, their characteristics, applications, and examples. 1. JIS Parallel Pipe Thread (JIS B 0202) Designation: PF (Equivalent to

1. Incident Overview In chemical production or other industrial scenarios involving instrument heat tracing and steam systems, errors during the welding of heat tracing pipes can lead to severe issues. For example, heat tracing pipes may be mistakenly connected to oil system pipelines in the steam system or accidentally linked to isolated oil systems during

The installation height of combustible and toxic gas detectors is a critical factor in ensuring the safety and effectiveness of gas detection systems. Proper installation height depends on the physical properties of the gas, the characteristics of the detection environment, and the location of potential gas release points. Below is a detailed guide on determining

Instrument verification and calibration reports are critical documents in the metrology industry. Companies often conduct testing and measurement to obtain these certificates, which serve two primary purposes: ensuring compliance with regulatory audits and maintaining cost control to support smooth production operations. However, are verification and calibration reports the same? What are the key differences between
