Foam pig, shell-shaped appearance, the head is spherical or parabolic, the outer diameter is about 3% ~ 5% larger than the inner diameter of the pipeline, the tail is a butterfly concave, the internal core is high-density foam, externally coated with high strength, good toughness and oil resistance of strong polyurethane material.
The foam pig has an outer diameter that is approximately 3% to 5% larger than the pipeline’s inner diameter. It is made of a durable polyurethane material that offers excellent toughness and resistance. The foam pig’s superior sealing performance creats a pressure differential between its front and rear, propelling it forward through the pipeline.
(1) Remove liquid accumulation and debris (dust) in the pipe, reduce friction loss, and improve the transmission efficiency of the pipeline;
(2) Sweep away the sediment and corrosion products of the pipe wall to reduce under-scale corrosion;
(3) For many other uses such as pipeline inspection;
