PU Coating Foam Pig

The PU Coating Foam Pig used on the pipeline is a type of plastic foam. The length of the polyurethane foam pig is 1.75~2 times the diameter of the pipe. Its interference is generally 25 mm or 5% to 10% of the pipe diameter. Therefore, it has high elasticity, toughness, and certain wear resistance. And its deformation is more than 50%. The foam pig has a strong passing ability and is easy to pass through the elbow. And it can pass through with its high deformability even if it is blocked. Or the user can increase the pressure to crush it. In this way, the blockage of the pipeline can be removed by itself, and no pressure-holding accident will occur. Moreover, the foam debris of the foam pig has no damage to the inner wall of the pipeline. So it can clean pipes with inner wall coating.

Description

The PU Coating Foam Pig used on the pipeline is a type of plastic foam. The length of the polyurethane foam pig is 1.75~2 times the diameter of the pipe. Its interference is generally 25 mm or 5% to 10% of the pipe diameter. Therefore, it has high elasticity, toughness, and certain wear resistance. And its deformation is more than 50%. The foam pig has a strong passing ability and is easy to pass through the elbow. And it can pass through with its high deformability even if it is blocked. Or the user can increase the pressure to crush it. In this way, the blockage of the pipeline can be removed by itself, and no pressure-holding accident will occur. Moreover, the foam debris of the foam pig has no damage to the inner wall of the pipeline. So it can clean pipes with inner wall coating.

But its disadvantage is the general ability to remove debris. Its primary function is to absorb water and clean the pipeline. And it can only be used once and has a shorter running distance than other pigs.

This product of ours is made of foam rubber or foam plastic. Its shape is a cylinder with a conical head. Hardened steel brushes with wear-resistant carbide are cross-wound on their outside. Its main feature is soft, easy-to-pass 900 bends with a small radius of curvature. It can remove impurities such as scale and corrosion products in the pipeline.

PU Coating Foam Pig product features:

Wide adaptability:

According to the design requirements of a long-distance pipeline, valves, tee, and elbow parts will be in the pipeline. At the same time, in order to meet the design requirements, such components sometimes differ from the wall thickness of the pipeline. Moreover, the insufficient bending radius of the pipe elbow will cause the internal diameter of the pipe to change. Therefore, there are certain risks when we use conventional pigs. However, the polyurethane foam pig is due to its elastic and compressible properties. Therefore, it can smoothly pass through such pipes without being blocked. At the same time, we can also customize various diameters and structural forms according to the requirements of the pipeline.

Long-running distance:

The polyurethane foam pig has good wear resistance. Even if there are deformations and dislocations caused by different pipe diameters in the pipeline. Polyurethane foam pigs can also be elastically deformed to pass without jamming and damage.

Good cleaning effect:

The polyurethane foam pig can fit closely with the pipeline when it is deformed. So it can clean up the dead ends of the pipes very well. However, the sealing area of ​​the polyurethane foam pig in contact with the inner wall of the pipeline is large. All its straight sections are tightly combined with the pipe wall. This can completely remove the dirt on the pipe wall. And it can be cleaned with a multi-layer cleaning method. Multi-layer cleaning refers to filling the cleaning agent between two polyurethane foam balls. This makes the cleaning process easier. It can also save the construction cost of the pipeline cleaning operations.

The requirements for supporting equipment are not high, and the operation is simple:

When the mechanical pig does not have a receiving and serving device, it is more difficult to collect and serve. In addition, safety protection must be done when the ball is played, and it needs to be completed by experienced on-site construction personnel. Due to its elastic deformation ability, the polyurethane foam pig can adapt to various complex working conditions. It has the advantages of low construction cost, less investment, and high economic benefits.

Green and environmentally friendly, no pollution to the environment:

The production process of the polyurethane foam pig does not produce pollutants and can be reused. It does not cause damage to the pipeline during construction. And the whole cleaning and cleaning process can achieve non-destructive operation.

The pipeline is cleaned evenly and thoroughly without affecting normal production.

1Polyurethane foam pigs have the characteristics of high elasticity and are not easy to break. The product can carry detection equipment, which can detect the internal conditions of the pipeline during operation. At the same time, it carries a tracker to monitor the running status of the pig.

Pipe cleaning is an operation that cleans the inner wall of the pipe to prevent scaling. During the transportation of oil, some viscous substances are often deposited on the inner wall of the pipe. Especially waxes in crude oil transportation. We have several pigging stations on the pipeline. The wax removal work is generally carried out at the pigging station, and the pig is put into the pig from the entrance. The scraper pig moves forward with the conveyed material. It can scrape off the sticky substances attached to the inner wall of the pipe to achieve the purpose of cleaning the pipe.

The following is the role of pigs in pipeline cleaning:

Natural gas pipeline in use:

it can clear a variety of sundries. Examples include water accumulation in pipelines, light oil, methane hydrate, and iron oxide carbide dust. There are also magical erosive substances, such as two bowls of carbon and hydrogen acid. In addition, it can reduce the corrosion damage to corrosive substances to the inner wall of the pipeline. And in this way, the direction of the pipeline can be re-defined and the deformation of the pipeline can be detected. It can also check the valve integrity rate along the line and reduce the working back pressure.

Crude oil pipeline in use:

And it can clean the pipeline before detection in the pipeline. It can also run pipelines intermittently at low volumes to clean up the pipeline. This product can remove condensed oil, and wax deposits, and scale inside the pipeline. In this way, the purpose of reducing the oil back pressure, reducing the friction resistance, and reducing the oil temperature can be achieved.

Chemical materials and edible oil pipelines:

Clean up the pipelines of polymeric materials: isolate different pipeline transportation media to realize single-pipe multi-product transportation and metering pipeline transportation medium.
In the new pipeline:

Sectional pigging and line sweeping pressure test:

Remove debris, floating rust, drainage, and exhaust in the pipeline.

General pigging pressure test:

To detect pipeline deformation and construction quality. Exhaust before the hydraulic test, drain before production, dry, medium isolation.

Water delivery and water injection pipelines:

Remove scale and sediment.

Pigging operations and their significance

The pigging operation depends on: the type of pig, the propelled medium pressure, and the control operating speed. According to different purposes, choose different pigs. For example, for cleaning or descaling purposes. In addition, it is advisable to control the running speed to 8 km/h. Remove fluid buildup in the tubing. Its operation should not cause the water hammer phenomenon. The operating speed of the intelligent pig depends on the performance of the instrument, generally 8 to 10 kilometers per hour.

Regular pigging operations can remove mechanical impurities and deposit-free water in the natural gas pipelines in transit. During the construction and long-term operation of gas pipelines, some harmful substances will be deposited. Such as natural gas condensate, water, solid impurities, electrolytes, etc.; reduce mechanical impurities and effusion.

Therefore, we need to further protect the metering facilities, pressure regulating facilities, and inner sealing surfaces of the valves in the gas transmission station. This can improve the quality of air, and pipeline transportation efficiency, and reduce the corrosion of the inner wall of the pipeline. It can also detect and track the internal situation of the pipeline in time. This ensures that the gas pipeline runs in a safe and stable state. Therefore, the service life of the pipeline can be extended.
