30 Years' Expertise in liquid transfer and pigging system
Why Pigging Systems? At the end of a product transfer, some material inevitably remains in the pipeline, causing waste and economic loss. Traditional methods, such as flushing with water or cleaning agents, are inefficient, incomplete, time- and labor-intensive, and generate large volumes of wastewater and pollutants.
A pigging system is designed for pipeline cleaning, maintenance, and product recovery. It works by propelling a pig—slightly larger than the pipeline’s inner diameter—through the line using compressed air (or nitrogen) or cleaning liquids. The pig effectively scrapes the inner walls, pushing residual product to a recovery container, enabling thorough cleaning while maximizing product recovery and minimizing waste. The pig’s outer layer is made from elastic, wear-resistant materials such as polyurethane or special rubber, and often contains built-in magnets for position tracking via magnetic sensors.

By recovering the remaining valuable product in the pipeline, the BJVP pigging system directly reduces material waste, lowers production costs, and thus improves the profitability of the enterprise. Companies are able to use raw materials more efficiently and reduce additional procurement costs due to lost products.
When transferring different media, the remaining liquid can be swept into any designated branch pipeline, thereby avoiding cross-contamination.
Highly efficient residue removal minimizes product waste and ensures 99.8%+ material recovery rate.
When the liquid transfers through the main pipe, the remaining liquids can be swept to any designated branch pipe so that the cross contamination will be avoided, adaptation to diverse process requirements.
Easy to operate, simple to manage, eliminating costly human mistakes.
Significantly reduces pipeline infrastructure requirements and saves valuable floor space - up to 40% less piping compared to traditional systems.
The pigging system reduces the use of wastewater and other cleaning agents generated by flushing pipes, reducing environmental pollution, and achieve sustainable development.
Pigging systems are Widely used in a variety of industries such as:
1. Paints & Coatings
2. Chemical Additives
3. Lubricating Oils
4. Food & Beverage
5. Petroleum and NaturalGas
6. Pharmaceutical & Biotechnology
Helping businesses reduce waste and increase profitability.
Recover product, efficiently remove residue, and withstand demanding conditions including high temperatures, high pressure, corrosive media, and frequent operations. Pipelines typically utilize welded or flanged connections for sealing performance, primarily serving the oil & gas, chemical industry.
Prioritize thorough cleaning, zero residue, and contamination-free processes. After pigging, pipelines are flushed with water or cleaning agents. For rapid disassembly and sanitation, hygienic tri-clamp (Tri-Clover) connections are used, making them ideal for food, pharmaceutical, and cosmetic industries.
Main Equipment in Pigging System Includes: Launching/Receiving Stations(Core Components), Intermediate Pigging Stations, Cleaning Pigs (various materials, Such as Foam Pigs), Piggable Pipeline Sections, Reinforced Pipe Sleeves, Pig Tracking Sensors, Industrial-Grade Communication Cabling, PLC-Based Control System, Pig Loader/Unloader(Optional) and Control Systems.
Pig launcher & receiver for efficient, safe pipeline cleaning & product recovery
The PLC system provides centralized monitoring of the pigging station, including: 1. Product valve actuation status (open/closed); 2. Pneumatic control valve positions; 3. Real-time pig tracking through the pipeline. Pigging Station Utility Parameters Valve & Cylinder: 304SS, Power Supply: 24V DC, IP Rating: IP65, Design Pressure: 20 bar, Temperature Range: -30°C to 120°C, Average Ball Speed: 1.0-1.5 m/s, Actuation Pressure: 5-8 bar.
The pigging station of the pipeline cleaning system is the core component of pipeline cleaning technology, mainly used for the launch, reception, and control of cleaning balls (sweeping balls).

Made of elastic material, good sealing and wear resistance
A pigging pig is an elastic projectile with a diameter slightly larger than the pipeline’s inner diameter, made of elastic materials (such as rubber or polyurethane). Driven by the medium inside the pipeline (gas or liquid), it performs cleaning tasks. Typically cylindrical with conical ends for smooth passage through bends. Advanced sensors and control systems can be embedded to monitor position and speed in real time, enabling precise control and automation.
VP adopts advanced global polyurethane manufacturing technology and has developed solutions with different materials for various operating conditions, ensuring excellent elasticity, sealing, and wear resistance. Common materials include: Composite PU, Fluoroelastomer, Silicon Rubber, and Steel Brush.
Industrial-grade pigging pigs feature a modular, detachable structure (large-diameter body and lips) for easy maintenance and cost reduction.
Sanitary-grade pigging pigs use a seamless one-piece design to eliminate dead zones and prevent residue buildup.
A pigging system uses pigging pigs to efficiently recover products, clean, or separate media inside pipelines. The operation steps are as follows:
1. Launch Preparation: Insert the pigging pig into the launching station and close the inlet valve.
2. Pig Propulsion: Use a driving medium (air, nitrogen, or cleaning liquid) to push the pig into the pipeline, where it scrapes the pipe wall and moves forward.
3. Product Recovery: The pig pushes residual liquid to the receiving station for recovery.
4. Pig Retrieval: After completing the task, the pig enters the receiving station and is collected through valve switching.
5. System Reset: The pig returns to the launching station, ready for the next operation.

Smart Pigging Control: Automated, Safe & Efficient Operations
Pipeline Pigging Control System is an automated or semi-automated system designed to manage and control pipeline pigging operations. It ensures the safe and efficient operation of Pigs within pipelines, enabling them to perform tasks such as cleaning, inspection, isolation, or media transfer.
BJVP control center is equipped with a comprehensive set of software and hardware for DCS control, where control systems are tested before shipment, Remote Control service and support is available to the customers, Compliant with Industrial Automation Safety Standards (IEC 61131-3).
Central control room master control (on-site monitoring).
On site control (central control room monitoring).
The system enforces a single control right through a permission interlock protocol to avoid signal conflicts and security risks caused by dual control operations.
Minimize resistance and wear for smooth pigging
Long Radius Elbows are necessary to ensure Pig move through smoothly in a pipping system. BJVP designs and manufactures long radius elbows in various types of materials.
1. The straight pipe segment between two elbows shall not be less than 10D;
2. Elbows must be equipped with straight pipe segments at both ends, with a length not less than 1.5D;
3. Elbows shall not connect directly to the pigging station; a straight pipe of ≥6D is required;
4. Standard angles of 45°, 60°, and 90° are recommended for elbows; non-standard angle elbows should not be used;
5. Elbows must have a bending radius of 5D or larger;
6. Each pigging station requires independent support, with supports every 4–6 m along the pipeline.
