Description

In pipeline cleaning operations, pigging accessories play a crucial role in optimizing flow, preventing corrosion, and clearing blockages. These versatile devices, used in conjunction with pipeline-cleaning pigs, are equipped with various components that enhance their cleaning capabilities and enable efficient inspection and maintenance. In this article, we will explore the key pigging accessories, their functions, and the materials from which they are made.

Types of Pigging Accessories

Gauging Disc: Accurate Detection and Enhanced Cleaning Efficiency

One essential component of pigging accessories is the gauging disc, which is located in the middle of the pig. It serves multiple purposes, including detecting pipeline deformations and improving cleaning efficiency. Typically made of aluminum, the gauging disc is designed to have a diameter ranging from 80% to 95% of the inner diameter of the pipe. This sizing ensures effective impurity removal and enhances the overall transmission efficiency of the pipeline. Additionally, the gauging disc aids in isolating different media, conducting pressure tests, and identifying pipeline corrosion.

Magnetic Steel: Rust Absorption and Maintenance

Another critical accessory is magnetic steel, often crafted from NdFeB material, which possesses the unique ability to absorb rust within the pipeline. Rust accumulation is a common problem in metal pipelines, leading to reduced efficiency and potential damage. By incorporating magnetic steel into pigging accessories, it becomes possible to mitigate these issues and maintain a clean pipeline interior.

Steel Brush: Thorough Cleaning of Residual Medium

Steel brushes, usually made of carbon steel or nylon, are employed as pigging accessories to tackle stubborn deposits and residual media within pipelines. These brushes are placed at the front end of the pig, offering excellent cleaning efficacy. The robustness of the steel brush ensures the thorough removal of debris and contaminants, contributing to improved pipeline performance.

Spring Steel Brush: Enhanced Cleaning Efficiency and Flexibility

The spring steel brush serves a similar purpose to the standard steel brush but with added flexibility. Constructed using carbon steel and nylon materials, the spring steel brush is strategically positioned within pigging accessories. This configuration enhances cleaning effectiveness by accommodating bends and curves within the pipeline, ensuring optimal removal of residues and deposits.

Carbon Steel Body: Structural Integrity and Connectivity

The carbon steel body forms the main structure of pigging accessories, ensuring the overall durability and connectivity of the components. By utilizing carbon steel, which offers excellent strength and resistance to corrosion, the pigging accessories can withstand the demanding conditions encountered during cleaning operations. The carbon steel body is connected to the cup, creating a sturdy and reliable assembly.

Guide Disc: Smooth Entry and Extended Durability

Made from polyurethane, the guide disc assists pigging accessories during pipeline entry, providing support and extending the running distance. This accessory plays a critical role in ensuring the smooth insertion of the pig into the pipeline. Additionally, the guide disc increases the durability of both the front disc and the cup, enhancing the overall longevity of the pig.

Transmitter: Accurate Pig Location and Tracking

The transmitter serves as an essential accessory for pigging operations. Its primary function is to transmit signals, enabling accurate tracking and locating of the pig within the pipeline. By incorporating a transmitter into pigging accessories, operators can precisely monitor the pig’s progress, ensuring comprehensive coverage and efficient cleaning.

Cups: Versatile Polyurethane Components

Cups, composed of polyurethane, constitute the primary components of pigging accessories. These integral elements provide the necessary sealing and traction to propel the pig through the pipeline. Polyurethane offers excellent wear resistance and durability, enabling the pig to traverse the pipeline smoothly and efficiently.
