During the\noperation of the main oil pipelines, paraffin deposits form on the inner\nsurface of the pipes, which leads to a decrease in its cross section. The\nthroughput of the pipeline worsens, the quality of the pumped product\ndecreases. Pipe wear and contamination of valves occur. As a result, the cost\nof pumping the product increases. Therefore, it is necessary to timely and\naccurately diagnose and clean the inner surface of the pipes from\nasphalt-resin-paraffin deposits.<\/p>\n\n\n\n
Cleaning\nthe inner cavity of the pipe using polyurethane balls allows to get high\nquality cleaning. This reduces wear, clogging, prevents the reduction of\nthroughput and increases the efficiency of the systems and its durability.<\/p>\n\n\n\n
Using\npolyurethane balls allows:<\/p>\n\n\n\n
- – to clean the interior surfaces of oil pipelines from paraffin and dirt,<\/li>
- – to displace the product and foreign objects from the pipes,<\/li>
- – to separate multi-stage oil products during sequential pumping along the internal cavity of the pipeline.<\/li><\/ul>\n\n\n\n

Due to the properties of the material, polyurethane balls with a metal core<\/a><\/em><\/strong> or without<\/a> it, are used as spare parts for diaphragm pumps for pumping highly viscous and chemically aggressive media (food industry, pulp and paper industry, petrochemical industry).<\/p>\n\n\n\n
Mill loading balls<\/strong><\/p>\n\n\n\n
Balls made\nof polyurethane with a metal core are used as loading balls for mills. Grinding\npolyurethane balls are used for soft grinding and grinding of soft samples in\nlaboratory planetary mills in testing laboratories.<\/p>\n\n\n\n
Cleaning sieves of screens (screen cleaners)<\/strong><\/p>\n\n\n\n
Without\nforced cleaning of the sieves during screening mixtures, after a while the\nsieve is clogged, the amount of sifted product is reduced. Cleaning sieves of\nscreens with the use of polyurethane balls increases the permeability of the\nproduct.<\/p>\n\n\n\n

Balls made\nof polyurethane are durable and wear resistant. They are resistant to repeated\ndeformations and have low abrasion.<\/p>\n\n\n\n
The shape\nof the ball and the trajectory of movement (rotation) of the polyurethane ball\nin the pipeline during cleaning ensure its uniform wear during prolonged use.\nThe average mileage of a ball made of polyurethane is from 200 to 400 km. When\nwashing pipes with polyurethane balls, ball sticking does not occur. The ball easily\npasses all the bends of the narrowing of the pipeline without damage.<\/p>\n\n\n\n
Polyurethane balls are highly resistant to oils and chemically aggressive environments. Easily tolerate temperature fluctuations from -40 \u00b0 C to +70 \u00b0 C. They have dielectric properties. (more info ..<\/a><\/em>).<\/strong><\/p>\n\n\n\n

<\/figure><\/li><\/ul><\/figure>\n\n\n\nHow to choose balls for cleaning the pipeline<\/p>\n\n\n\n
During\noperation of the pipeline due to corrosion, the wall thickness decreases, while\nthe layer of internal deposits on the walls increases. This leads to a decrease\nin the actual internal diameter of the pipeline. Therefore, the selection of\nballs must be made according to the actual value of the inner diameter of the\npipeline and the state of the wall of the pipeline.<\/p>\n\n\n\n
Polyurethane company produces uniform balls from solid polyurethane with a diameter of 25 mm to 70 mm of various hardness and color (more about the relationship between color and hardness of polyurethane ..<\/a><\/em>).<\/strong><\/p>\n\n\n\n
- PU54 \/ M71 – hardness 71 units Shore A, orange<\/li>
- PU54 \/ M80 – hardness 80 units Shore A, green<\/li>
- PU54 \/ M87 – hardness 87 units Shore A, blue<\/li>
- PU54 \/ K92 – hardness 92 units Shore A, black<\/li><\/ul>\n\n\n\n
It is\npossible to manufacture polyurethane balls of different hardness, diameter and on\nindividual request.<\/p>\n\n\n\n
For effective cleaning of the pipeline, a set of balls of various hardness is required – from \u201cespecially soft\u201d 55 units Shore A to \u201csolid\u201d 65-95 units Shore A. At the first start, a soft ball is applied first, then balls with increasing hardness. The use of balls of different hardness allows you to go through narrowing up to 30% of the inner diameter of the pipe and bends at an angle of 900 with a turning radius of up to one inner diameter.<\/p>\n\n\n\n
