Structural features:
The material and pressure bearing capacity of the pig receiving/sending tube must meet the design and medium requirements. Several types of quick-opening blind plates such as clamp type, lock ring type, and buckle type can be selected. They all have reasonable structure and good sealing performance. And it has the advantages of quick opening and closing, convenient operation, safety, and reliability.
At the same time, the button-type quick-opening blind plate has the properties of convenient opening and safe self-locking. (Blind plate self-locking, anti-vibration, anti-loosening, and secondary pressure relief when opening). Which makes the operation more concise and safe; the clamp-type quick opening. In addition to the safety self-locking of the blind plate, when the blind plate is locked. There is no relative rotation between the sealing ring and the sealing surface, and the sealing ring is not easily damaged, thus better protecting the sealing system. Like the blind plate, it has an enormous pressure-bearing capacity and good performance.

Pipe cleaning:
Pipes have great advantages in long-distance transportation. However, deposits or fouling may form on the inner wall of the pipe during long-term use. If grease or wax deposits are formed on the inner wall of the oil pipeline, coke and carbon deposits will also be formed in the industrial gas pipeline. In order to improve the safety factor and service life of the pipeline. Pigs commonly work for cleaning in the oil industry
Pig cleaning relies on the pressure of the fluid in the pipeline being cleaned. Or powered by water or air pressure provided by other equipment. This power pushes the pig to move forward in the pipeline, scraping the dirt off the pipe wall. It can push the dirt and debris accumulated in the pipe out of the pipe. The advancement of the pig in the pipeline is driven by the pressure difference between the front and rear. There are two specific driving methods. One is to use the back pressure of the fluid as the driving force for the pig to walk. It also clears the dirt ahead of the pig in the pipeline as it advances. This method is suitable for cleaning shorter pipes.
PIPELINE PIGS
Another way is to use the pressure created by the fluid leaking from the pig perimeter. This pulverizes the dirt adhering to the pipe wall. Then drain the stain out. This method is more suitable for cleaning long pipes.
The outer diameter of the pig is usually 3%-5% larger than the inner diameter of the pipeline. It has a tight combination with the pipeline. Therefore, it is highly airtight during operation. This makes it easy to clean up the dirt. Especially when we use the liquid as escort fluid. The jet it forms has a strong impact on the dirt on the pipe wall.
Types of pigs
Pigs have two kinds: ordinary pigs and intelligent pigs according to their structure and function.
Ordinary pig
Common pigs have different structures and types. There are two main types: spherical (ie pigging ball) and cylindrical. Cylindrical pigs usually include straight plate pigs, disc pigs, and soft foam pigs. It also includes straight disc mixing pigs, straight plate diameter measuring pigs, disc type diameter measuring pigs, straight plate steel brushing pigs, and other forms.
Intelligent pigging device
The intelligent pig has high-resolution flux leakage technology. It can collect various data on pipeline conditions. Then we process the collected data by computer. In this way, various information such as pipe corrosion, profile, deformation, wall thickness, cracks, the position of pipe width fittings, etc. can be obtained. During the operation of the intelligent pig, the satellite positioning system can also work for positioning. The structure and principles of intelligent pigs are different.
The supporting wheel pig is on the inside of the front and rear leather cups of the ordinary pig. It increases the number of rollers along the perimeter. The rollers support the pig’s body by the spring circumference. Pig Launchers also make the friction between the pig and the pipeline rolling friction. This pig is installed by installing various sensors and detectors. It can detect the profile, deformation, wall thickness, cracks, and other information about the pipeline.
SMART PIGS
Bidirectional electronic pigs can operate in both directions. Therefore, when the pipe is blocked, it can be returned to its original position. It usually adopts a polyurethane leather bowl, which has a strong passing ability. It is wear-resistant and has a long life. Its electronic positioning transmitter is a modified high-performance electronic positioning transmitter. It has a long working time and high power. A dedicated high-performance battery is built into the product. Charging is unnecessary, and the working time is more than 200h. When a jam occurs, the location of the jam can be quickly found by using the positioning receiver. This product uses a conical leather bowl. It has a strong passing ability and good sealing performance. It can still pass through when the pipe is distorted. Pigging ranges from 10cm to over 100cm.
The universal joint intelligent leather bowl pig has all the advantages of a full intelligent pig.
And its new features are as follows:
- Firstly, the pig skin bowl can be attached at will according to the needs, and the pigging train can be formed conveniently and quickly. It can also achieve one launch and multiple missions. Such as completing the tasks of scraping wax, cleaning, removing water (rust), and coating;
- Secondly, the leather bowl is made of imported new materials, and the strength can exceed 2 000km in one way;
- And then, the hanging and dismounting method is adopted, and the installation and dismounting are convenient and simple;
- At last, any elbows, expansion joints, etc. can pass it.
Intelligent pigs use ultrasonic technology to detect blockage and corrosion of pipelines. Intelligent pigs can also use frequency identification technology. It can exclude geomagnetic interference and some electromagnetic interference. At the same time, it can work in the field away from electromagnetic interference. So if the intelligent bigger adopts pattern recognition technology, it can eliminate all kinds of geomagnetic and electromagnetic interference. And it can also work on almost any occasion.
PIPELINE CLEANING
The pipeline runs for a long time. At the same time, it is affected by the temperature, type, and viscosity of the conveying medium. After the pipeline has been running for a period of time, the pipeline cleaning operation needs to be performed. This improves pipeline efficiency. Just as the elderly with hyperlipidemia need regular infusions, keep the blood vessels open.
The pig enters the inside of the pipeline through the teeing device. It is driven by the pressure of the pipeline itself to push the medium forward. During the cleaning process, we will install the pig with leather bowls, steel brushes, magnets, and other components. This performs corresponding cleaning operations on the inside of the pipeline. Our common pigs have the following kinds.
1. Foam pig
Firstly, the foam pig is the first step in the pigging operation. This is also the safest step. Its main material is soft material. Surface cast polyurethane. Once the blockage occurs, the foam pig can be broken after increasing the operating pressure of the pipeline. This will not cause the phenomenon of pipeline stoppage and jamming.
2. Leather bowl pig
Secondly, it consists of a sealed leather bowl, a supporting straight leather bowl, an isolation pad, and a skeleton. It has a strong passing ability. Compared with the straight plate pig, the sealing performance of the leather cup pig is better. But not bidirectional.
3. Straight plate pig
And then, it consists of a sealing straight leather bowl, a supporting straight leather bowl, an isolation pad, and a skeleton. It has a strong passing ability. The straight leather bowl pig is bidirectional. If the pig is blocked, the pig can be returned to the ball through the reverse transfer of the pipeline medium.
4. Steel brush pig
It consists of a sealing leather bowl, supporting leather bowl, isolation pad, steel brush, and frame. It is suitable for pigging operations where impurities or wax deposits are attached to the inner wall of the pipeline. The cleaning ability of the steel brush pig is stronger than that of the square plate pig and the leather cup pig.
5. Diameter plate pig
Add a caliper aluminum plate to the cup pig or straight plate pig. It can check for deformation inside the pipe.
6. Magnetic pigging device
At last, it can absorb rust and all magnetic media inside the pipeline. It is suitable for welding slag, iron, or other ferromagnetic substances in the pipeline. The magnetic pig is equipped with a strong magnetic block in the middle of the skeleton. It can effectively adsorb magnetic media
