Description

Introduction

The Pig Indicator-2 Inch Base Welded, offered by EMT, is a vital instrument in the oil and gas industry that plays a crucial role in detecting the passage of cleaning pigs within pipelines. These pig signalers provide valuable information to operators, enabling them to monitor pipeline conditions and ensure the safe and efficient transportation of oil and gas.

Functions and Use Effects

The primary function of the Pig Indicator-2 Inch Base Welded is to detect the passage of cleaning pigs within pipelines. It is strategically installed at critical points, such as pig launching and pig receiving locations, as well as other crucial points along the pipeline. When a pig passes through the pig signaler’s location, it triggers a response that is transmitted to the control room, indicating the pig’s passage. This real-time information is vital for pipeline operators to monitor the condition of the pipeline and identify any potential issues or maintenance requirements promptly.

With the Pig Indicator-2 Inch Base Welded, operators can accurately track the location of the cleaning pig within the pipeline. By monitoring the pig’s progress, operators can identify and address problems such as corrosion, cracking, or other damage that may require maintenance or repair. This proactive approach ensures the safe and efficient transportation of oil and gas while minimizing downtime and operational disruptions.

4. Easy Maintenance: This pig indicator does not use dynamic seals, which translates to lower maintenance costs and simplified emission controls. Additionally, the design facilitates easy installation, operation, and maintenance, saving valuable time and resources for operators.
5. Enhanced Safety: The Pig Indicator-2 Inch Base Welded complies with NACE MR 0175 standards, ensuring its suitability for pipeline applications where corrosive elements are present. It also possesses explosion-proof properties (Exd II BT4), providing an added layer of safety during operation.

Operation Cautions and Working Principle

To ensure accurate and reliable operation of the Pig Indicator-2 Inch Base Welded, operators must follow essential cautions. Firstly, the flag should be manually reset to the non-triggered state by pressing it down, ensuring it is in a horizontal position, before using the pig signaler. When the trigger is pushed by the passing pig, the flag swings more than 45 degrees, indicating the pig’s passage through the pipeline at that specific location.

The working principle of the Pig Indicator-2 Inch Base Welded is based on a simple yet effective mechanism. Installed inside the pipeline, it physically interacts with the passing pig. When the pig makes contact with the pig signaler, the trigger mechanism is activated, causing the flag shaft to rotate 90° from a horizontal state to an upright position. Operators can determine the pig’s location within the pipeline by observing the flag’s position. This rotation is facilitated by a torsion spring, ensuring a swift and accurate response to pig passage.
