Pig Launcher Type A

Description

The Pig Launcher and receiver skid is composed of the skid body, receiver, and launcher. And medium inlet and outlet pipes, blowdown pipes, and vent pipes. And the receiver and launcher have connections with the medium inlet and outlet pipes, blowdown pipes, and vent pipes. The receiver and launcher, medium inlet and outlet pipes, and the blowdown pipes are all fixed on the skid base. An inlet and outlet ball valve are installed at the end of the medium inlet and outlet pipe. The vent pipeline has equipment with a ball valve, vent ball valve, and safety valve. The receiving and launching cylinder is also provided with a pressure gauge and a ball passing indicator. The two blowdown pipes have respectively equipment with blowdown ball valves.

The Pig Launcher and receiver skid can ensure convenient installation by users. It can work only by putting the skid into the corresponding pipeline connection end and connecting the main pipe port. Thus avoiding repeated installation and commissioning during pigging at different positions of the pipeline.

The function of the receiver launcher skid is to clean the pipeline regularly to prevent the reduction of pipe diameter due to the accumulation of sundries in the pipeline transmission medium, affecting the transmission efficiency. Especially for new pipelines, since sundries are not cleaned up during construction. It is necessary to clean up the sundries in the pipeline before the water test and operation of the pipeline.

So if you have any other questions, please contact our professionals to answer them for you.

Purpose of regular cleaning of pipelines:

1. Natural gas pipeline in operation. Remove water, light oil, methane hydrate, iron oxide, carbide dust, carbon disulfide, hydrogen sulfuric acid, and other corrosive substances inside the pipeline. Reduce the corrosion damage to corrosive substances to the inner wall of the pipeline. Redefine the pipeline direction. Detect pipeline deformation, and check the integrity of valves along the line. Reduce the working back pressure.
2. And then the operation of the Oil Pipeline. Pigging before pipeline inspection and intermittent operation of oil pipeline with low throughput to remove condensate, wax, and scale inside the pipeline to reduce oil back pressure, reduce abrasion resistance and reduce oil temperature.
3. Chemical material and edible oil pipeline. Clean the polymerizable material pipeline, and isolate different pipeline transmission media. Realize single pipe multi-variety transmission, and measure pipeline transmission media.

Maintenance of Pig Launcher skid:

1. Firstly, check whether the indication of each instrument on the receiver and launcher is normal every day;
2. Check whether the connection parts of the container and quick opening blind plate have leakage;
3. Tighten the bolts at the joints of the spherical cylinder every quarter;
4. Regularly inspect the rust spots of the spherical cylinder, remove the rust and prevent corrosion of the rust spots found;
5. At last, open the ball cylinder regularly every year to check the inside and check whether the sealing rubber ring is damaged. Seal the sealing part of the quick opening manhole cover and conduct anti-rust treatment on the screw.

Maintenance precautions:

1. The Pig Launcher and receiver skid are pressure vessels, and the maintenance personnel must obtain the pressure vessel operation certificate;
2. Before opening the ball cylinder, check whether the pressure gauge has pressure to ensure that it operates under no pressure;
3. Necessary explosion-proof tools, fire extinguishers, fire blankets, and other facilities are fully prepared during operation;
4. The operation of opening and closing blind plate shall be carried out by one person and supervised by other personnel;
5. In the process of opening and closing the quick opening blind plate, you must stand on the side of the blind plate. So no one can stand in front of the quick opening blind plate to prevent safety accidents.

In the pipeline to be cleaned, the staff shall place the corresponding series of pigs according to the requirements of the operation. The outer edge of the pig cup is elastically sealed with the inner wall of the pipeline. It is powered by the pressure difference generated by the pipeline medium. This power will push the pig along the pipeline. The scraping and scouring effect of the pig itself or the tools it carries. With this power, we can remove scale or deposits in the pipeline

There are many kinds of pigs working for pipeline pigging, which has three types

Type:

1. Pig ball. (round rubber ball);
2. Cup pig. (sizing pig, caliper pig, isolation Pig, two-way pig, etc.);
3. Foam pig. (high, medium, and low-density foam pig).

The advantage of the cup pig is that it can maintain a fixed direction when running in the pipeline. It can carry various testing instruments and other devices. Such as detecting the deformation amount of the pipe. It can replace the medium and clean the space inside the pipe. It can also remove the rust on the pipe wall.
