EMT Polyurethane Spherical Foam Pigs

The material used for the spherical foam pigs is neoprene, known for its corrosion-resistant properties. We offer two variants of this product: solid balls and hollow balls. The selection between the two depends on the diameter of the pipeline.

Description

The material used for the spherical foam pigs is neoprene, which is known for its corrosion resistance. We offer two variants of this product: solid balls and hollow balls. The choice between the two depends on the diameter of the pipe.

For pipes with diameters greater than 100mm, we recommend using hollow balls. The wall thickness of these hollow balls should be one-tenth of the inner diameter of the pipe. Each hollow sphere is equipped with an air nozzle and filled with water in the center. If the pipe diameter is less than 100mm, solid balls are preferred.

Spherical Foam Pigs

During the colder months, it is important to replace the water in the hollow spheres with a water-based antifreeze such as ethylene glycol. This prevents the product from freezing and ensures smooth operation even in winter conditions.

When the spherical foam pig is working in the pipeline, it needs to maintain a certain sealing property. To do this, the outer diameter of the sphere must be greater than the inner diameter of the gas pipeline.

Before use, the hollow pig ball must be filled with water. After water injection, the diameter of the ball should exceed the inner diameter of the pipe by 5% to 8%.

We offer three types of injector to meet your needs: standard injector, manual booster pump injector and electric booster pump injector.

Features of Spherical Foam Pigs

1. It can completely remove solid and liquid debris from the pipe

2. Neoprene raw materials have high corrosion resistance

3. There are two kinds of solid ball and hollow ball

4. The product is environmentally friendly. Does not cause air and liquid leakage

5. Good wear resistance. reusable

6. There are a variety of specifications, you can choose according to your needs

The term “interference” refers to the difference between the outside diameter of the ball and the inside diameter of the tube. When the ball is not filled with water, the interference is 2% of the inner diameter of the tube. However, once water is filled, the interference increases to 3%-5%. This adjustment allows the ball to adhere tightly to the wall of the tube, preventing any air or liquid leakage.

Although the main function of the pigging ball is to drain fluid from the pipe and separate the medium, it is less effective at removing larger lumps. In addition, it does not have the ability to carry testing instruments in a certain direction, nor can it be used as a traction tool for these instruments.

Spherical Foam Pigs

Advantages of Spherical Foam Pigs

Polyurethane spherical foam pigs have several significant advantages. They are resistant to oil, allowing them to maintain their function and integrity in oil-rich environments. In addition, they can withstand harsh conditions, including high acidity or alkalinity, proving their durability. Their anti-aging properties ensure that they maintain their effectiveness and structural integrity over long periods of use. They are also resilient at high temperatures, expanding their range of applications. To extend service life, these foam cleaners reduce the need for frequent replacement, saving costs in the long run. Its rugged design and ability to resist various factors greatly simplify the design, construction, production and maintenance processes of pipeline engineering, bringing considerable convenience and benefits.

Spherical Foam Pigs Water Injection Method

1. Use a screwdriver to remove the plug from the ball mouth.

2. Insert the hollow needle of the water injection device into the guide hole of the ball nozzle, and then forcibly Pierce the rubber core.

3. Make sure the exhaust valve is closed and the inlet valve is open. First measure the outside diameter of the ball.

4. Exhaust treatment every 3 to 5 minutes. This involves closing the exhaust valve, opening the inlet valve, and repeating the process several times. In between these cycles, water is continued until the diameter of the ball reaches the desired size.

5. When the correct diameter is reached, close the inlet valve and take out the hollow needle. Put a little grease on the plug diagram and tighten it.

What’s more, our packing boxes do not need to be fumigated, thus simplifying and speeding up the shipping process.

Our mission is to deliver high quality spherical foam pig in a timely and efficient manner, and customer satisfaction is our constant goal.

Conclusion

Our company offers a wide range of best-in-class spherical foam pig for every pipe maintenance requirement. These products are made of corrosion-resistant neoprene rubber and come in two variants: solid balls and hollow balls to accommodate different pipe diameters. They are filled with water (in colder months or antifreeze), ensuring an effective seal inside the pipe and reducing any risk of leakage.

Our spherical foam pig is not only durable and resistant to harsh conditions, but also environmentally friendly with excellent wear resistance and reusable. Although their primary function is to drain fluids and separate media inside pipes, they cannot remove larger objects or act as a traction tool for inspection instruments.

After extensive testing, our products meet high standards in terms of hardness, wear resistance, tensile strength and resilience. Its rugged design and oil resistance make it a cost-effective long-term solution for pipeline engineering.

We are always committed to providing excellent customer service and our representatives are here to help you 24/7. Our fast delivery and safe, efficient packaging ensure that you receive your order in perfect condition and time. In our company, customer satisfaction is the driving force behind everything we do. Believe in all our spherical foam pigs need.
