Description

Definition of polyurethane foaming pig

The polyurethane foaming pigs mainly composed of leather bowls, skeletons, connectors, etc., are all made of polyurethane material and can carry electronic transmitters. It has the characteristics of strong passing ability, large deformation, high strength, not easy to jam, strong adaptability to the elbow, and so on. It is mainly used for pigging and descaling of long-distance pipelines with complicated natural conditions and irregular scaling. Our company can design different types of soft pigs according to the actual situation of the pipeline.

Advantage of polyurethane foaming pig

Wide adaptability: According to the design requirements of a long-distance pipeline, there will be valves, tees, and elbow parts in the pipeline. At the same time, such parts, in order to meet the design requirements, sometimes have differences with the wall thickness of the pipeline, the bending radius of the pipeline elbow is insufficient, and other reasons, resulting in changes in the internal diameter of the pipeline. There will be certain risks with conventional pigs. So it can be smoothly through this kind of pipeline without jam and customized according to the requirements of various diameters and structural forms.

Long-running distance: polyurethane foaming pig appliance has good wear-resisting properties. There are split-layer caused by deformation and different pipe diameters in the pipeline. Polyurethane foaming pigs can pass through elastic deformation without jamming and damage.

 

Good cleaning effect: polyurethane foaming pig in deformation can also be closely combined with the pipe wall, and can be very good for cleaning the dead corner of the pipeline; The polyurethane foaming pig has a large contact sealing area with the inner wall of the pipe, and all the straight sections are tightly combined with the pipe wall to completely remove the dirt on the pipe wall; Multi-layer cleaning can be used. Multi-layer cleaning refers to filling the cleaning agent between two polyurethane foam balls, making the cleaning process more simple and saving the construction cost of the pipeline cleaning operation.

 

Supporting equipment requirements are not high, simple operation: mechanical pig without receiving, serving device, receiving, serving more difficult, and out of the ball to do a good job of safety protection, the site construction personnel should be experienced to complete; Polyurethane foaming pig has the advantages of low construction cost, less input personnel, and high economic benefit because of its elastic deformation ability, can adapt to various complex working conditions.

 

Green environmental protection, no pollution to the environment: polyurethane foaming pig production process does not produce pollutants, can be reused; No damage is caused to the pipeline in the construction process, and the whole cleaning and cleaning process is lossless.

Pipelines are cleaned evenly and thoroughly, without affecting normal production; Due to its characteristics of high tearing and not easy to break, polyurethane foaming pig can carry detection equipment, which can detect the inside of the pipeline during operation, and carry a tracker to monitor the running state of the pig.

Feature of polyurethane foaming pig

 

1. Compact structure

The whole system is held together very tightly, the mandrel and the tail flange are molded together, all the cleaning bowl isolation ring brushes and other components are stacked on the front, and the front friction and pressure are applied back to the shaft. If the front fastening nut is loose, the whole system will never unravel and the mandrel will be sufficiently tensioned and threaded through the pipe as the component thickness and structure change.

 

2. Good cleaning effect and uniform wear

The mandrel is made of hard, hollow polyurethane, The whole weight of the system is over 35 % lower than that of the metal structure. The bending and cleaning effect of the system is better than that of the steel shaft system. Because of its lightweight, the leather bowl is not easy to deform in the pipeline, so the pipeline cleaning is uniform so that the components wear evenly. The hollow polyurethane shaft is easier to bend than the steel shaft, and the ability to pass is strong. When the bend turns sharply, the risk of being touched and damaged is small, and the pipe will never be stuck in the pipe because the curvature radius of the pipe bend is small.

 

3. Components (such as wire brush or polyurethane scraper or steel scraper and other auxiliary cleaning parts) can be prepared or assembled according to the user’s needs. It can be completely assembled or reassembled by one person operating independently. The combined system can complete pipeline cleaning, water removal, metering products, isolation, wax removal, rust removal, pipe coating, and water pressure test.

 

4. Can be prepared and assembled according to user needs

The system can be formulated or combined with components (such as wire brush or polyurethane scraper or steel scraper and other auxiliary cleaning components) as required by the user. It can be completely assembled or reassembled by one person operating independently. The combined system can complete pipeline cleaning, water removal, metering products, isolation, wax removal, rust removal, pipe coating, and water pressure test.

 

5. Good flexibility, strong sealing

The structure is designed to make two or three leather bowls sealed, thus improving the flexibility and tightness of the pig. Valves and elbows are allowed through any form of the piping interface (weld).

 

6. Lightweight, high strength

This type of pig is more than 50 percent lighter with no loss of strength or life compared to other metal pigging structures. The solid and durable polyurethane body is an order of magnitude stronger than a metal pig, with additional head reinforcement if needed.

 

7. Low price, wide use

Economic integration, no expensive spare parts, neither scattered in the pipe nor stuck in the pipe. No need for maintenance, with good performance and price ratio. It can be used for pipe cleaning, scraping wax, and descaling inside coating anti-corrosive layer, but also for pipe emptying full hydraulic test, and fluid isolation.
