Pig pigging technology

Pig is a bullet-like material made of special polyurethane material and has strong shrinkage.

high strength. Pig cleaning technology is a way to remove fouling, sediment or foreign matter from pipes.

technology. The working principle is that after the Pig is put into the transmitter, the emission medium is advanced in Pig.

The direction creates a pressure difference, forming a forward thrust, allowing Pig to advance along the pipeline, after running

In the process, Pig is slightly deformed. The Pig itself or its accessories continuously accumulate in the tube with the tube wall

Contact with scale, crushing, scraping, scouring, vibrating, crushing, removing pipes

Scale, sediment and foreign matter inside. At the same time, the needle is passing through the Pig cylinder and tube.

When the gap formed by the inner wall forms a high-speed annulus jet, under its action, the front

Will form a pseudo-vacuum-like area that is good for the operation of the Pig and is scraped

The slag is impacted and stirred, and discharged out of the pipe in time, effectively preventing the slag from being in the pipe

The accumulation inside avoids the occurrence of blockage.

Pig cleaning technology is characterized by long, short distance, large diameter, and scale

The quality is relatively soft, the cleaning of difficult-to-dissolve pipes, the cleaning time is short, and the installation is simple,

Convenient, no environmental pollution, efficient, economical,

With Pig cleaning technology, the pipes to be cleaned should meet the following conditions:

1. A metal or non-metal pressure pipe that can withstand pressure.

2. Pipes with a pipe diameter greater than 50mm.

3. The radius of the national pipe diameter elbow is not less than 1.5 times the pipe diameter.

4. The maximum deformation of the pipe diameter is not more than 20% of the pipe diameter.

5. The intercept valve on the pipeline shall be a ball valve or a dry gate valve.

6. The inner diameter of the pipe parts on the pipe is the same as the inner floor of the pipe.

7. Pipeline fare quality temperature is not one 70C.
